ES1BL RVG Equivalent & Substitute Parts

Part Overview

The ES1BL RVG 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 ES1BLH.

Substitute parts are necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when design specifications permit operation with equivalent electrical characteristics within defined parameter ranges.

Substitute Part Grouping Explanation

Substitution of the ES1BL RVG is determined by the following critical parameters:

Mandatory Matching Parameters:

Voltage - DC Reverse (Vr) (Max): 100 V
Package / Case: DO-219AB (Sub SMA / SMF variants)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

Current - Average Rectified (Io): Equal or greater than 1 A
Voltage - Forward (Vf) (Max) @ If: Within acceptable forward voltage drop range
Reverse Recovery Time (trr): Equal or faster than 35 ns
Current - Reverse Leakage @ Vr: Equal or lower than 5 µA @ 100 V
Operating Temperature - Junction: Equal or wider range than -55°C to 150°C

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts with identical electrical specifications and packaging, differing only in product status, packaging format (Tape & Reel vs. individual), or automotive qualification grade.

Similar Parts: Parts meeting the mandatory matching parameters with allowable variations in current rating, forward voltage, or recovery time characteristics, provided these variations do not exceed the specified limits.

Engineering Selection Recommendations

Parametric Equivalents (Direct Substitutes):

ES1BL and ES1BLH are parametric equivalents of ES1BL RVG with identical electrical specifications. ES1BL differs only in packaging format (Tape & Reel) and product status (Not For New Designs). ES1BLH provides the same electrical performance with automotive-grade qualification (AEC-Q101) and is suitable for applications requiring automotive compliance. Both maintain the same 100 V reverse voltage, 1 A current rating, and 35 ns reverse recovery time.

Similar Parts with Current Rating Variations:

ES07B-GS08 (Vishay) is rated for 500 mA average rectified current, which is lower than the 1 A requirement of ES1BL RVG. This part is suitable only for applications where the actual circuit current does not exceed 500 mA. ES07B-GS18 (Vishay) is rated for 1.2 A, exceeding the 1 A specification and providing additional current margin. Both Vishay parts feature faster reverse recovery time (25 ns vs. 35 ns) and lower reverse leakage current (10 µA vs. 5 µA).

Similar Parts with Recovery Time Variations:

RS07B-GS08 (Vishay) is rated for 500 mA with a reverse recovery time of 150 ns, which exceeds the 35 ns specification of ES1BL RVG. This part is not suitable for applications requiring fast recovery characteristics.

Higher Current Rating Alternative:

VS-2EFH01HM3/I (Vishay FRED Pt® series) is rated for 2 A average rectified current with superior performance characteristics: 16 ns reverse recovery time, 2 µA reverse leakage current, and extended operating temperature range (-65°C to 175°C). This part is suitable for applications requiring higher current capacity and improved thermal performance.

Product Status Consideration:

ES1BL and ES1BLH are marked "Not For New Designs." For new product development, ES1BL RVG (Active status) or active alternatives such as ES07B-GS18, RS07B-GS08, or VS-2EFH01HM3/I are recommended.

Frequently Asked Questions (FAQ)

Q: Can ES1BL (Tape & Reel packaging) be used as a direct substitute for ES1BL RVG?

A: Yes. ES1BL is a parametric equivalent with identical electrical specifications. The difference is packaging format and product status. ES1BL is supplied in Tape & Reel format and is marked "Not For New Designs," whereas ES1BL RVG is Active status. Electrical performance is identical.

Q: Is ES1BLH suitable for automotive applications?

A: Yes. ES1BLH carries AEC-Q101 automotive qualification and is suitable for automotive-grade applications. It maintains identical electrical specifications to ES1BL RVG with the addition of automotive-grade certification.

Q: Can ES07B-GS08 replace ES1BL RVG in all applications?

A: No. ES07B-GS08 is rated for 500 mA average rectified current, which is half the 1 A rating of ES1BL RVG. It can only be used in applications where the actual circuit current does not exceed 500 mA. Verify circuit current requirements before substitution.

Q: What is the advantage of VS-2EFH01HM3/I over ES1BL RVG?

A: VS-2EFH01HM3/I provides higher current capacity (2 A vs. 1 A), faster reverse recovery time (16 ns vs. 35 ns), lower reverse leakage current (2 µA vs. 5 µA), and extended operating temperature range (-65°C to 175°C vs. -55°C to 150°C). It is suitable for applications requiring higher performance and thermal margin.

Q: Are all substitute parts available in DO-219AB package?

A: Yes. All listed substitute parts use the DO-219AB package (Sub SMA or SMF variant), ensuring mechanical and thermal compatibility with the original ES1BL RVG footprint.

Q: Why is RS07B-GS08 listed as a substitute if it has 150 ns recovery time?

A: RS07B-GS08 is listed as a similar part but is not recommended for applications requiring fast recovery characteristics. The 150 ns recovery time exceeds the 35 ns specification of ES1BL RVG. Substitution is only appropriate for applications where recovery time is not a critical parameter.

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

A: Both are Vishay parts with identical voltage and recovery specifications. ES07B-GS08 is rated for 500 mA, while ES07B-GS18 is rated for 1.2 A. ES07B-GS18 provides current capacity matching or exceeding the 1 A requirement of ES1BL RVG and is the preferred Vishay alternative for direct current replacement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant, meeting environmental and regulatory requirements equivalent to ES1BL RVG.
