HS1GL RTG Equivalent & Substitute Parts

Part Overview

The HS1GL RTG 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 is RoHS3 compliant with REACH unaffected designation.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when design revisions call for equivalent electrical performance from different manufacturers or product lines.

Substitute Part Grouping Explanation

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

Parametric Equivalents share identical or functionally equivalent electrical specifications:

Voltage - DC Reverse (Vr) (Max): 400 V
Current - Average Rectified (Io): 1 A
Voltage - Forward (Vf) (Max) @ If: 1.3 V @ 1 A
Package / Case: DO-219AB (Sub SMA)
Operating Temperature - Junction: -55°C to 150°C
RoHS Status: ROHS3 Compliant

Parametric equivalents may differ in reverse recovery time (trr), capacitance characteristics, and packaging format (Cut Tape vs. Tape & Reel), but maintain electrical performance within the same application envelope.

Similar Parts share the same package and voltage rating but operate at reduced current ratings (700 mA vs. 1 A) and employ different recovery characteristics. These parts are suitable only when the application current requirement does not exceed the lower rating.

Engineering Selection Recommendations

For Direct Substitution (Parametric Equivalents):

ES1GL RVG and HS1GL RVG are direct parametric equivalents to HS1GL RTG. Both maintain the 400 V / 1 A electrical specification and DO-219AB package format. ES1GL RVG and HS1GL RVG are classified as Active product status, ensuring continued availability and manufacturing support. Both parts are RoHS3 compliant and REACH unaffected, meeting regulatory requirements identical to the primary part.

HS1GL RVG is the preferred equivalent when maintaining the same base product line (HS1G series) is required. ES1GL RVG provides an alternative from the ES1G series with improved reverse recovery time (35 ns vs. 50 ns), resulting in lower switching losses in high-frequency applications.

ES1GL is a parametric equivalent but carries Not For New Designs product status, limiting its use to legacy system maintenance or existing inventory utilization only.

For Current-Limited Applications:

S07G-GS08 and S07G-GS18 are similar parts from Vishay General Semiconductor rated for 700 mA average rectified current. These parts are suitable only when the application circuit operates at or below 700 mA. Both parts carry AEC-Q101 automotive qualification and Active product status. Selection between S07G-GS08 and S07G-GS18 depends on reverse leakage measurement conditions (400 V vs. 200 V specification).

Frequently Asked Questions (FAQ)

Q: Can ES1GL RVG replace HS1GL RTG in all applications?

A: ES1GL RVG is a parametric equivalent with identical voltage and current ratings. The primary difference is reverse recovery time (35 ns vs. 50 ns). In applications where switching frequency and recovery characteristics are not critical design parameters, ES1GL RVG provides direct substitution. Applications involving high-frequency switching or stringent EMI requirements should evaluate the faster recovery time as a design benefit rather than a compatibility concern.

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

A: HS1GL RVG and HS1GL RTG are both from the HS1G base product line with identical electrical ratings (400 V, 1 A, 1.3 V forward voltage). The primary difference is packaging format: HS1GL RTG is supplied in Sub SMA format, while HS1GL RVG is supplied in Tape & Reel (TR) format. Both maintain the same reverse recovery time (50 ns) and capacitance characteristics within specified tolerances. Selection depends on manufacturing process requirements (cut tape vs. reel-fed assembly).

Q: Are Vishay S07G-GS08 and S07G-GS18 suitable replacements?

A: S07G-GS08 and S07G-GS18 share the 400 V voltage rating and DO-219AB package but are rated for 700 mA average rectified current, not 1 A. These parts are suitable only when the application circuit operates at or below 700 mA continuous current. If the design requires 1 A capability, these parts are not appropriate substitutes. Both parts carry AEC-Q101 automotive qualification, making them suitable for automotive applications within their current rating.

Q: Why does ES1GL show "Not For New Designs" status?

A: ES1GL carries Not For New Designs product status, indicating the manufacturer has transitioned this part number to newer alternatives. Existing inventory remains available for legacy system support and maintenance. New designs should specify ES1GL RVG (Active status) or HS1GL RVG (Active status) instead. ES1GL is appropriate only for sustaining production of existing products or emergency replacement scenarios.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) affects switching speed and switching losses. HS1GL RTG and HS1GL RVG specify 50 ns trr, while ES1GL and ES1GL RVG specify 35 ns trr. Faster recovery (lower trr) reduces switching losses and EMI in high-frequency applications. In low-frequency or DC applications, trr differences have negligible impact on circuit performance. Application frequency and power dissipation requirements determine whether trr differences are significant.

Q: Can packaging format be changed between Cut Tape and Tape & Reel?

A: Packaging format (Cut Tape vs. Tape & Reel) affects manufacturing process compatibility, not electrical performance. Cut Tape format (ES1GL) is suitable for manual assembly or low-volume pick-and-place operations. Tape & Reel format (ES1GL RVG, HS1GL RVG) is required for high-speed automated assembly lines. Selection depends on manufacturing equipment and production volume, not circuit application requirements.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts (ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, S07G-GS18) are RoHS3 compliant. All parts are REACH unaffected. Regulatory compliance is maintained across all substitution options.
