ES1GL RQG Equivalent & Substitute Parts

Part Overview

The ES1GL 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 35 nanoseconds, making it suitable for applications requiring rapid switching performance.

Alternative equivalent and substitute parts are necessary when the ES1GL RQG becomes unavailable, when specific packaging formats are required for manufacturing processes, or when design requirements necessitate components with comparable electrical characteristics from different manufacturers or product lines.

Parametric Equivalent Parts (ES1GL RQG, ES1GL RVG, HS1GL RVG) maintain identical or functionally equivalent electrical specifications across voltage, current, and forward voltage ratings. These parts are interchangeable at the circuit level when packaging format requirements are met.

Similar Parts (S07G-GS08, S07G-GS18) share the same package and voltage rating but operate at reduced current capacity (700 mA versus 1 A). These parts are suitable for applications where the lower current rating is acceptable and do not require the full 1 A specification.

Engineering Selection Recommendations

Parametric Equivalent Selection (ES1GL RVG, HS1GL RVG):

ES1GL RVG is the primary parametric equivalent to ES1GL RQG. Both components maintain identical electrical specifications across all critical parameters including voltage rating, current capacity, forward voltage, and reverse recovery time. ES1GL RVG is available in Tape & Reel packaging format and carries Active product status, making it suitable for new designs and high-volume manufacturing applications.

HS1GL RVG is also a parametric equivalent with Active product status. This part exhibits a slightly longer reverse recovery time (50 ns versus 35 ns) and higher capacitance (15 pF versus 8 pF), which may affect performance in applications with stringent switching speed requirements. HS1GL RVG remains compliant with all regulatory requirements and is suitable for applications where the extended recovery time is acceptable.

Alternative Equivalent Selection (ES1GL):

ES1GL is a parametric equivalent available in Cut Tape and Digi-Reel packaging formats. This part carries Not For New Designs product status, indicating it is maintained for legacy applications and existing designs only. ES1GL should not be selected for new product development.

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

S07G-GS08 and S07G-GS18 are similar parts manufactured by Vishay General Semiconductor. These components share the same 400 V voltage rating and DO-219AB package but operate at 700 mA average rectified current, representing a 30% reduction in current capacity compared to the ES1GL RQG specification. Both parts feature Standard Recovery characteristics (>500 ns) with significantly longer reverse recovery time (1.8 µs), making them unsuitable for applications requiring fast switching performance. These parts carry AEC-Q101 automotive qualification and are suitable only for applications where the reduced current rating and slower recovery characteristics are acceptable.

Frequently Asked Questions (FAQ)

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

A: Yes. ES1GL RVG is a parametric equivalent with identical electrical specifications. Both components share the same voltage rating (400 V), current capacity (1 A), forward voltage (1.3 V @ 1 A), and reverse recovery time (35 ns). The primary difference is packaging format: ES1GL RQG is supplied in Sub SMA format while ES1GL RVG is supplied in Tape & Reel format. Verify that your manufacturing process accommodates Tape & Reel packaging.

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

A: Both parts meet the primary electrical specifications of 400 V reverse voltage and 1 A current capacity. HS1GL RVG exhibits a longer reverse recovery time (50 ns versus 35 ns) and higher junction capacitance (15 pF versus 8 pF). These differences may impact switching performance in high-frequency applications. HS1GL RVG is suitable for applications where the extended recovery time does not compromise circuit performance.

Q: Can S07G-GS08 or S07G-GS18 replace ES1GL RQG?

A: S07G-GS08 and S07G-GS18 are similar parts with the same voltage rating and package but reduced current capacity (700 mA versus 1 A). These parts are suitable only if your application requires less than 700 mA average rectified current. Additionally, these parts feature Standard Recovery characteristics (1.8 µs) compared to the Fast Recovery characteristics (35 ns) of ES1GL RQG, making them unsuitable for applications requiring rapid switching performance.

Q: Why is ES1GL marked as Not For New Designs?

A: ES1GL carries Not For New Designs product status, indicating that Taiwan Semiconductor Corporation has designated this part for legacy applications only. New product designs should select ES1GL RVG or HS1GL RVG, both of which carry Active product status and are supported for ongoing production.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed in this reference—ES1GL RQG, ES1GL, ES1GL RVG, HS1GL RVG, S07G-GS08, and S07G-GS18—carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance.

Q: What packaging formats are available for equivalent parts?

A: ES1GL RQG is supplied in Sub SMA format. ES1GL RVG and HS1GL RVG are supplied in Tape & Reel format. ES1GL is supplied in Cut Tape and Digi-Reel formats. S07G-GS08 and S07G-GS18 are supplied in Tape & Reel format. Verify that your manufacturing equipment and assembly process support the selected packaging format.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All parts listed maintain an operating temperature range of -55°C to 150°C junction temperature, ensuring compatibility across thermal specifications.

Q: What is the Moisture Sensitivity Level for these parts?

A: All parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
