Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

ES1BL and ES1BLH are parametric equivalents of the HS1BL M2G, maintaining identical voltage and current ratings. Both parts are manufactured by Taiwan Semiconductor Corporation in the DO-219AB package. ES1BL carries "Not For New Designs" status, indicating it is in mature phase. ES1BLH includes automotive-grade qualification (AEC-Q101) and is suitable for applications requiring automotive reliability standards. Both parts demonstrate improved reverse recovery time (35 ns versus 50 ns) and are RoHS3 compliant.

For Higher Current Applications:

ES07B-GS18 (Vishay, 1.2 A) and VS-2EFH01HM3/I (Vishay, 2 A) exceed the 1 A current requirement while maintaining 100 V voltage rating and DO-219AB package compatibility. ES07B-GS18 is suitable for applications requiring marginal current headroom. VS-2EFH01HM3/I provides the highest current capacity (2 A) with the fastest reverse recovery time (16 ns) and lowest reverse leakage (2 µA). Both Vishay parts carry Active product status and AEC-Q101 automotive qualification.

For Lower Current Applications:

ES07B-GS08 (Vishay, 500 mA) is suitable only for applications where the circuit current requirement does not exceed 500 mA. This part is not recommended as a direct replacement for the HS1BL M2G in circuits designed for 1 A operation.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and REACH unaffected status. Parts with automotive qualification (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) are suitable for automotive applications requiring AEC-Q101 certification. The HS1BL M2G itself does not carry automotive qualification and is classified as standard grade.

Frequently Asked Questions (FAQ)

Q: Can ES1BL be used as a direct replacement for HS1BL M2G?

A: ES1BL is a parametric equivalent with identical voltage (100 V) and current (1 A) ratings in the same DO-219AB package. The primary difference is product status: ES1BL is marked "Not For New Designs," indicating mature lifecycle phase. Electrically, ES1BL provides improved performance with faster reverse recovery time (35 ns versus 50 ns). ES1BL is suitable for replacement in existing designs.

Q: What is the difference between ES1BL and ES1BLH?

A: Both parts are parametric equivalents with identical electrical ratings (100 V, 1 A). ES1BLH includes automotive-grade qualification (AEC-Q101) and is designated for automotive applications. ES1BL is standard grade. Both have identical reverse recovery time (35 ns) and reverse leakage (5 µA @ 100 V). Selection between these parts depends on application requirements for automotive certification.

Q: Can VS-2EFH01HM3/I replace HS1BL M2G in all applications?

A: VS-2EFH01HM3/I exceeds the HS1BL M2G specifications in current capacity (2 A versus 1 A) and provides superior performance characteristics including faster reverse recovery time (16 ns versus 50 ns) and lower reverse leakage (2 µA versus 5 µA). The part maintains 100 V voltage rating and DO-219AB package compatibility. This part is suitable for replacement and provides performance margin. Extended operating temperature range (-65 to 175°C versus -55 to 150°C) provides additional thermal margin.

Q: Why would ES07B-GS08 not be suitable as a replacement?

A: ES07B-GS08 is rated for 500 mA average rectified current, which is 50% of the HS1BL M2G rating (1 A). This part is unsuitable for circuits designed to operate at 1 A. Using an undersized current-rated diode in a 1 A circuit creates thermal stress and reliability risk. ES07B-GS08 is only appropriate for applications with confirmed maximum current requirements not exceeding 500 mA.

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

A: All substitute parts use the DO-219AB (Sub SMA) surface mount package, ensuring mechanical and footprint compatibility. However, packaging format (tape & reel, cut tape, or bulk) varies by part number and supplier. ES1BL and ES1BLH are supplied in Tape & Reel format. ES07B-GS08 is supplied in Cut Tape & Digi-Reel format. ES07B-GS18 and VS-2EFH01HM3/I are supplied in Tape & Reel format. Verify packaging format with supplier for procurement requirements.

Q: Which substitute part is recommended for new automotive designs?

A: For new automotive designs requiring AEC-Q101 qualification, VS-2EFH01HM3/I is the recommended selection. This part carries Active product status, automotive-grade designation, and AEC-Q101 qualification. It provides superior electrical performance (16 ns reverse recovery time, 2 µA reverse leakage) and extended operating temperature range (-65 to 175°C). ES1BLH is an alternative if the 1 A current rating is sufficient and the extended temperature range of VS-2EFH01HM3/I is not required.

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

A: Reverse recovery time (trr) indicates the speed at which the diode transitions from forward conduction to reverse blocking. The HS1BL M2G has 50 ns trr. Substitute parts with lower trr values (ES1BL/ES1BLH at 35 ns, Vishay parts at 16-25 ns) switch faster, reducing switching losses and electromagnetic interference. Lower trr is beneficial in high-frequency switching applications. In low-frequency rectification applications, trr differences have minimal impact on circuit performance.

Q: Are there any compliance or certification differences between substitute parts?

A: All parts are RoHS3 compliant and REACH unaffected. Automotive-grade parts (ES1BLH, ES07B-GS08, VS-2EFH01HM3/I) carry AEC-Q101 qualification, suitable for automotive applications. The HS1BL M2G is standard grade without automotive certification. ES1BL is also standard grade. Selection of automotive-qualified parts is mandatory for automotive applications; standard-grade parts are not acceptable substitutes in automotive designs.
