Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. The ESH1BHE3_A/I carries automotive-grade qualification per AEC-Q101, which is the highest qualification standard among the listed parts.

Vishay General Semiconductor Parts (ESH1BHE3_A/I, ESH1B-E3/61T, VS-1EMH01-M3/5AT): These parts share common manufacturer origin and maintain consistent compliance certifications. The VS-1EMH01-M3/5AT operates within the FRED Pt® series and demonstrates improved reverse recovery time (15.2 ns) compared to the main part (25 ns), while maintaining all critical electrical parameters.

Taiwan Semiconductor Corporation Parts (ESH1B, ESH2BA): These parts provide equivalent electrical performance with identical primary ratings. The ESH1B demonstrates faster reverse recovery time (15 ns) than the main part. The ESH2BA maintains identical reverse recovery time (25 ns) to the main part and specifies reverse leakage current at 200 V, providing additional margin.

Selection among substitute parts depends on inventory availability, supply chain requirements, and design flexibility across qualified manufacturers. All parts are suitable for direct substitution in applications requiring 100 V, 1 A general-purpose rectification in DO-214AC surface mount packages.

Frequently Asked Questions (FAQ)

Q: Can ESH1B-E3/61T replace ESH1BHE3_A/I in automotive applications?

A: Yes. Both parts are manufactured by Vishay General Semiconductor, share identical primary electrical ratings (100 V, 1 A, 900 mV forward voltage), and are packaged in DO-214AC (SMA). Both maintain ROHS3 compliance and Active product status. The ESH1B-E3/61T is available in higher inventory quantities (10,100 pcs vs. 965 pcs).

Q: What is the difference between VS-1EMH01-M3/5AT and ESH1BHE3_A/I?

A: Both parts meet identical voltage (100 V), current (1 A), and forward voltage (900 mV @ 1 A) specifications. The VS-1EMH01-M3/5AT operates within the FRED Pt® series and exhibits faster reverse recovery time (15.2 ns vs. 25 ns). Reverse leakage current is 2 µA @ 100 V compared to 1 µA @ 100 V for the main part. Both are surface mount DO-214AC packages with identical operating temperature range.

Q: Are Taiwan Semiconductor Corporation parts (ESH1B, ESH2BA) compatible with the Vishay ESH1BHE3_A/I?

A: Yes. Both ESH1B and ESH2BA meet all critical electrical parameters: 100 V reverse voltage, 1 A average rectified current, 900 mV forward voltage @ 1 A, fast recovery speed classification, and DO-214AC surface mount packaging. Both maintain ROHS3 compliance and -55°C to 175°C operating temperature range. Reverse recovery times are 15 ns (ESH1B) and 25 ns (ESH2BA), both within fast recovery classification.

Q: Does the automotive-grade qualification of ESH1BHE3_A/I affect substitution?

A: The ESH1BHE3_A/I carries AEC-Q101 automotive qualification. Substitute parts ESH1B-E3/61T and VS-1EMH01-M3/5AT are also manufactured by Vishay and maintain equivalent compliance. Taiwan Semiconductor Corporation parts (ESH1B, ESH2BA) do not specify AEC-Q101 qualification in the provided data. Design requirements for automotive applications should confirm qualification status with the manufacturer.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. All substitute parts share identical DO-214AC (SMA) package specifications and surface mount mounting type. PCB footprints, solder pad layouts, and assembly processes remain unchanged. No design modifications are required for mechanical or electrical integration.

Q: What is the significance of reverse recovery time variation among these parts?

A: Reverse recovery time (trr) ranges from 15 ns (ESH1B) to 25 ns (ESH1BHE3_A/I, ESH1B-E3/61T, ESH2BA). All values fall within the fast recovery classification (≤ 500ns, > 200mA). Faster recovery times reduce switching losses in high-frequency applications. Selection depends on specific circuit performance requirements and thermal management considerations.

Q: Are moisture sensitivity levels specified for all parts?

A: The main part ESH1BHE3_A/I does not specify Moisture Sensitivity Level (MSL) in the provided data. Substitute parts ESH1B-E3/61T, VS-1EMH01-M3/5AT, ESH1B, and ESH2BA all specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
