HS1GL RQG Equivalent & Substitute Parts

Part Overview

The HS1GL RQG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 400 V DC reverse voltage and 1 A average rectified current in a Sub SMA surface mount package (DO-219AB). This component is classified as Active product status and features fast recovery characteristics with a reverse recovery time of 50 ns, making it suitable for standard rectification applications requiring moderate switching speeds.

Equivalent and substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from qualified alternatives that meet the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the HS1GL RQG are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical or superior electrical specifications across all critical parameters: 400 V reverse voltage rating, 1 A average rectified current, 1.3 V forward voltage drop at 1 A, fast recovery speed classification, and DO-219AB package format. These parts differ only in packaging configuration (Cut Tape versus Tape & Reel) or minor variations in reverse recovery time (35 ns versus 50 ns) and junction capacitance (8 pF to 15 pF), which remain within acceptable operating ranges for general-purpose rectification.

Similar Parts share the same package and voltage rating but operate at reduced current ratings (700 mA versus 1 A) and employ standard recovery characteristics (>500 ns) rather than fast recovery. These parts are from an alternative manufacturer (Vishay) and include automotive-grade qualification (AEC-Q101). Selection of similar parts requires confirmation that the reduced current rating and slower recovery characteristics are acceptable for the target application.

The key parameters determining substitution eligibility are:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A (parametric equivalents) or 700 mA (similar parts)
Package / Case: DO-219AB
Mounting Type: Surface Mount
Speed Classification: Fast Recovery (parametric equivalents) or Standard Recovery (similar parts)

Engineering Selection Recommendations

Parametric Equivalent Selection (ES1GL RVG, HS1GL RVG, ES1GL)

The parts ES1GL RVG and HS1GL RVG are direct parametric equivalents to the HS1GL RQG, maintaining identical voltage and current ratings with fast recovery characteristics. Both are classified as Active product status, ensuring continued availability and manufacturing support. ES1GL RVG and HS1GL RVG are available in Tape & Reel packaging, suitable for high-volume automated assembly processes. The ES1GL is available in Cut Tape and Digi-Reel packaging formats but carries Not For New Designs status, limiting its use to legacy system support or inventory management scenarios.

Selection between HS1GL RVG and ES1GL RVG depends on packaging requirements and reverse recovery time tolerance. HS1GL RVG maintains the 50 ns reverse recovery time of the original part with 15 pF junction capacitance. ES1GL RVG offers improved reverse recovery performance at 35 ns with reduced junction capacitance of 8 pF, providing superior switching characteristics for applications sensitive to recovery time and capacitive effects.

Similar Part Selection (S07G-GS08, S07G-GS18)

The Vishay S07G-GS08 and S07G-GS18 diodes are similar alternatives from an alternative manufacturer, sharing the 400 V voltage rating and DO-219AB package format. These parts operate at 700 mA average rectified current, representing a 30% reduction from the 1 A rating of the HS1GL RQG. Both parts employ standard recovery characteristics (1.8 µs reverse recovery time) rather than fast recovery, and include automotive-grade qualification (AEC-Q101).

Selection of S07G-GS08 or S07G-GS18 is appropriate only when the application circuit operates at or below 700 mA average rectified current and when standard recovery speed is acceptable. The reduced current rating and slower recovery characteristics make these parts unsuitable as direct replacements in circuits designed for the full 1 A capability of the HS1GL RQG.

Compliance and Certification

All listed parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility across industrial and consumer applications. Moisture sensitivity level is uniformly classified as MSL 1 (Unlimited) across all parts, indicating no special moisture control requirements during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG be used as a direct replacement for HS1GL RQG in production?

A: Yes. ES1GL RVG is a parametric equivalent with identical voltage (400 V), current (1 A), and package (DO-219AB) specifications. The 35 ns reverse recovery time of ES1GL RVG is superior to the 50 ns of HS1GL RQG, and the reduced junction capacitance (8 pF versus 20 pF) provides improved high-frequency performance. Tape & Reel packaging is suitable for automated assembly. No circuit modifications are required.

Q: What is the difference between HS1GL RVG and ES1GL RVG?

A: Both are parametric equivalents with identical voltage and current ratings. HS1GL RVG maintains 50 ns reverse recovery time and 15 pF junction capacitance, matching the original HS1GL RQG performance profile. ES1GL RVG offers faster recovery at 35 ns and lower capacitance at 8 pF. Both are Active product status. Selection depends on whether the application benefits from improved switching speed and reduced capacitance.

Q: Why are S07G-GS08 and S07G-GS18 listed as similar rather than equivalent?

A: These Vishay parts differ in two critical parameters: current rating (700 mA versus 1 A) and recovery speed (standard >500 ns versus fast ≤500 ns). The 30% reduction in current rating makes them unsuitable for circuits designed to operate at full 1 A capacity. Standard recovery characteristics introduce significantly longer switching delays (1.8 µs versus 50 ns), affecting circuit performance in switching applications. These parts are suitable only when application requirements permit reduced current and slower switching.

Q: What packaging formats are available for equivalent parts?

A: HS1GL RQG is supplied in unspecified packaging format. Parametric equivalents are available in multiple formats: ES1GL in Cut Tape and Digi-Reel, ES1GL RVG in Tape & Reel, and HS1GL RVG in Tape & Reel. Tape & Reel format is standard for high-volume automated assembly. Cut Tape format is suitable for lower-volume or manual assembly processes. Digi-Reel is a bulk packaging option. All formats use the identical DO-219AB component package.

Q: Is ES1GL suitable for new designs despite Not For New Designs status?

A: ES1GL carries Not For New Designs product status, indicating that the manufacturer recommends against its use in new circuit designs. While electrically equivalent to HS1GL RQG, ES1GL should be reserved for legacy system support, field replacements, or inventory management of existing products. For new designs, select ES1GL RVG or HS1GL RVG, both classified as Active product status.

Q: Can these diodes be used in automotive applications?

A: HS1GL RQG, ES1GL, ES1GL RVG, and HS1GL RVG do not carry automotive-grade qualification. S07G-GS08 and S07G-GS18 are qualified to AEC-Q101 automotive standards. If automotive qualification is required, S07G-GS08 or S07G-GS18 must be selected, with confirmation that the 700 mA current rating and standard recovery speed are acceptable for the application.

Q: What is the significance of reverse recovery time in diode selection?

A: Reverse recovery time (trr) determines how quickly the diode transitions from conducting to blocking state when reverse voltage is applied. HS1GL RQG and HS1GL RVG specify 50 ns, while ES1GL and ES1GL RVG specify 35 ns. S07G-GS08 and S07G-GS18 specify 1.8 µs. Shorter recovery times reduce switching losses and electromagnetic interference in high-frequency applications. Longer recovery times are acceptable in low-frequency rectification circuits. Application switching frequency determines whether recovery time differences are significant.

Q: Are all parts RoHS3 compliant?

A: Yes. All listed parts (HS1GL RQG, ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18) are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory requirements for industrial and consumer electronics applications.
