ES1BL RTG Equivalent & Substitute Parts

Part Overview

The ES1BL RTG is a general-purpose rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 100 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 AEC-Q101 automotive qualification available in variant forms.

Substitute parts are necessary when the ES1BL RTG reaches end-of-life status, when alternative packaging formats are required for manufacturing processes, or when design specifications permit higher current ratings or improved performance characteristics within the same voltage class and package family.

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1BL and ES1BLH are parametric equivalents of ES1BL RTG with identical electrical performance. ES1BL is marked "Not For New Designs" and is suitable only for legacy system maintenance or repair applications. ES1BLH includes AEC-Q101 automotive qualification and is recommended for new automotive designs requiring the same 1 A, 100 V specification.

For Active Product Status with Enhanced Performance:

ES07B-GS18 (Vishay) is an Active product offering 1.2 A current rating with identical 100 V reverse voltage and improved reverse recovery time of 25 ns. This part is suitable for designs where higher current margin or faster switching performance is beneficial within the same thermal and package constraints.

ES07B-GS08 (Vishay) is an Active product with 500 mA current rating and AEC-Q101 qualification. This part is suitable only for applications where the 1 A requirement can be reduced to 500 mA, as it does not meet the minimum current specification of the ES1BL RTG.

VS-2EFH01HM3/I (Vishay FRED Pt® series) is an Active product with 2 A current rating, superior reverse recovery time of 16 ns, and extended operating temperature range (-65°C to 175°C). This part is suitable for high-performance applications requiring lower switching losses and wider temperature operation, with AEC-Q101 automotive qualification.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited). Parts with AEC-Q101 qualification (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) are suitable for automotive applications. Selection should be based on current requirement, switching performance needs, and product lifecycle status of the target application.

Frequently Asked Questions (FAQ)

Q: Can ES1BL RTG be replaced with ES1BL or ES1BLH?

A: Yes. ES1BL and ES1BLH are parametric equivalents with identical electrical specifications (100 V, 1 A, 35 ns reverse recovery time). ES1BL is marked "Not For New Designs" and should be used only for maintenance of existing systems. ES1BLH includes AEC-Q101 automotive qualification and is the preferred equivalent for new designs.

Q: What is the difference between ES07B-GS08 and ES07B-GS18?

A: Both are Vishay products in DO-219AB package with 100 V reverse voltage and Active product status. ES07B-GS08 is rated for 500 mA average rectified current, while ES07B-GS18 is rated for 1.2 A. ES07B-GS18 meets or exceeds the 1 A requirement of ES1BL RTG and is the appropriate Vishay substitute. Both have 25 ns reverse recovery time and AEC-Q101 qualification (ES07B-GS08 only).

Q: Can VS-2EFH01HM3/I be used as a direct substitute?

A: Yes, with design considerations. VS-2EFH01HM3/I meets all mandatory parameters: 100 V reverse voltage, DO-219AB package, surface mount, fast recovery speed, and ROHS3 compliance. It exceeds the 1 A current requirement with 2 A rating and offers superior performance with 16 ns reverse recovery time and extended temperature range (-65°C to 175°C). It is suitable for applications where higher current capacity and faster switching are acceptable.

Q: Are all substitute parts available in the same packaging format?

A: No. ES1BL RTG is supplied in standard packaging (format not specified in input). ES1BL is supplied in Tape & Reel (TR). ES1BLH is supplied in Tape & Reel (TR). ES07B-GS08 is supplied in Cut Tape (CT) & Digi-Reel®. ES07B-GS18 is supplied in Tape & Reel (TR). VS-2EFH01HM3/I is supplied in Tape & Reel (TR). Verify packaging compatibility with your assembly process before selection.

Q: Which substitute part has the best performance characteristics?

A: VS-2EFH01HM3/I offers the best performance with 16 ns reverse recovery time (versus 35 ns for ES1BL RTG), 2 µA reverse leakage current (versus 5 µA), and 2 A current rating. It also provides extended operating temperature range (-65°C to 175°C versus -55°C to 150°C) and AEC-Q101 automotive qualification. Performance improvement comes with higher current capacity, which may require circuit design verification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts (ES1BL, ES1BLH, ES07B-GS08, ES07B-GS18, VS-2EFH01HM3/I) are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: Which substitute parts have automotive qualification?

A: ES1BLH, ES07B-GS08, and VS-2EFH01HM3/I carry AEC-Q101 automotive qualification. ES1BL and ES07B-GS18 do not list AEC-Q101 qualification. For automotive applications, select from the qualified parts.

Q: What is the impact of different reverse recovery times?

A: Reverse recovery time (trr) affects switching speed and switching losses. ES1BL RTG has 35 ns trr. ES07B-GS08 and ES07B-GS18 have 25 ns (faster). VS-2EFH01HM3/I has 16 ns (fastest). Faster recovery reduces switching losses and heat generation, beneficial in high-frequency switching applications. Slower recovery (higher trr) is acceptable in lower-frequency applications.

Q: Can ES1BL RTG be replaced with a lower current rating part?

A: No. ES07B-GS08 is rated for 500 mA, which is below the 1 A requirement of ES1BL RTG. Using an undersized part creates risk of component failure under rated load conditions. Only use substitute parts with equal or higher current ratings.
