S1GL RVG Equivalent & Substitute Parts

Part Overview

The S1GL RVG 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. This component is classified as Active product status and is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Substitute parts become necessary when the primary part number reaches end-of-life status, inventory constraints occur, or design requirements necessitate alternative qualified sources. The S1GL RVG maintains electrical and mechanical compatibility with specific alternative diode models that share identical or functionally equivalent electrical characteristics within the 400 V rectifier diode category.

Substitute Part Grouping Explanation

Substitution eligibility for the S1GL RVG is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

Voltage - DC Reverse (Vr) (Max): 400 V minimum
Package / Case: DO-219AB (Sub SMA compatible)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Technology: Standard recovery rectifier

Secondary Compatibility Factors:

Current - Average Rectified (Io): Equal or greater rating

Operating Temperature Range: Minimum -55°C to 175°C junction temperature
Moisture Sensitivity Level: MSL 1 (Unlimited)

The S1GL part number from Taiwan Semiconductor Corporation qualifies as a parametric equivalent with identical electrical specifications but differs in packaging format (Tape & Reel versus bulk). The S07G-GS08 and S07G-GS18 from Vishay General Semiconductor represent similar manufacturer alternatives with reduced current rating (700 mA versus 1 A) but maintain full voltage compatibility and automotive-grade qualification (AEC-Q101).

Engineering Selection Recommendations

S1GL (Parametric Equivalent): This part maintains identical electrical specifications to the S1GL RVG across all critical parameters including voltage rating, current capacity, forward voltage, and reverse recovery time. The primary difference is packaging format (Tape & Reel versus bulk). However, this part carries "Not For New Designs" status, limiting its application to legacy system maintenance or existing inventory utilization only.

S07G-GS08 and S07G-GS18 (Similar Alternatives): Both Vishay parts provide full 400 V voltage compatibility and maintain identical reverse recovery time (1.8 µs) and forward voltage characteristics. The reduced current rating (700 mA versus 1 A) requires circuit-level verification to confirm adequate margin for the application's maximum current demand. Both parts carry Active product status and AEC-Q101 automotive qualification, providing long-term availability and enhanced reliability assurance. Operating temperature range is reduced to -55°C to 150°C junction temperature, which must be evaluated against application thermal requirements.

Selection between S07G-GS08 and S07G-GS18 depends on reverse leakage current specifications: S07G-GS08 specifies 10 µA @ 400 V, while S07G-GS18 specifies 10 µA @ 200 V, representing different measurement conditions.

Frequently Asked Questions (FAQ)

Q: Can the S1GL RVG be directly replaced with the S1GL part number?

A: The S1GL provides identical electrical performance across all specified parameters. However, the S1GL carries "Not For New Designs" status, restricting its use to replacement applications in existing systems. Packaging format differs (Tape & Reel versus bulk), which may affect procurement and assembly processes.

Q: What is the primary limitation of the S07G-GS08 and S07G-GS18 alternatives?

A: The current rating is reduced from 1 A to 700 mA. Applications requiring the full 1 A capacity must verify that circuit operation remains within the 700 mA maximum average rectified current limit. These parts are suitable for applications with lower current demands or where design margin permits operation at reduced current levels.

Q: Are the Vishay S07G-GS08 and S07G-GS18 parts suitable for automotive applications?

A: Both parts carry AEC-Q101 automotive qualification and Automotive grade designation, making them suitable for automotive-grade applications. The S1GL RVG does not carry automotive qualification.

Q: What is the difference between S07G-GS08 and S07G-GS18?

A: Both parts share identical electrical specifications and current ratings. The difference lies in reverse leakage current measurement conditions: S07G-GS08 specifies 10 µA @ 400 V, while S07G-GS18 specifies 10 µA @ 200 V. Selection depends on application leakage current requirements at the specific voltage of operation.

Q: Can the S1GL RVG be used in high-temperature applications?

A: The S1GL RVG supports operating junction temperatures up to 175°C. The Vishay alternatives (S07G-GS08 and S07G-GS18) support maximum junction temperatures of 150°C. Applications requiring operation above 150°C junction temperature must use the S1GL RVG or S1GL equivalent.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The S1GL RVG, S1GL, S07G-GS08, and S07G-GS18 are all ROHS3 compliant with REACH Unaffected status, meeting environmental regulatory requirements for commercial and industrial applications.

Q: What is the moisture sensitivity level for these diodes?

A: All listed parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.
