Substitute Part Grouping Explanation

Substitute parts for the ESH3D-M3/57T are classified based on strict electrical and mechanical parameter equivalence. The primary substitution criteria are:

Mandatory Equivalence Parameters:

Voltage - DC Reverse (Vr) (Max): 200 V
Current - Average Rectified (Io): 3 A
Package / Case: DO-214AB, SMC
Mounting Type: Surface Mount
Operating Temperature Range: -55°C minimum to 150°C minimum

Secondary Consideration Parameters:

Voltage - Forward (Vf) (Max) @ If: Acceptable range 900 mV to 1.2 V @ 3 A
Reverse Recovery Time (trr): Fast Recovery (≤500 ns) or Standard Recovery (>500 ns)
Current - Reverse Leakage @ Vr: 5 µA to 10 µA @ 200 V
Packaging Format: Tape & Reel (TR) or Cut Tape (CT)

Parts meeting all mandatory equivalence parameters are classified as direct substitutes. Variations in secondary parameters indicate performance trade-offs or application-specific suitability.

Engineering Selection Recommendations

ESH3D-E3/57T (Vishay): This part is a parametric equivalent to the ESH3D-M3/57T with identical electrical specifications and operating temperature range. Both devices are Active product status from the same manufacturer. The ESH3D-E3/57T is supplied in Tape & Reel packaging and maintains fast recovery characteristics with 40 ns reverse recovery time. Selection of this substitute is appropriate for direct replacement in applications where Vishay sourcing is preferred and inventory availability is a consideration.

ESH3DHE3_A/H (Vishay): This part meets all mandatory electrical equivalence parameters and is supplied in Cut Tape packaging format. The device carries automotive grade classification with AEC-Q101 qualification, making it suitable for automotive applications requiring formal qualification documentation. The operating temperature range extends to 175°C, matching the main part specification. This substitute is appropriate for applications requiring automotive-grade components or when Cut Tape packaging is acceptable.

S3D-TP (Micro Commercial Co): This part is classified as manufacturer recommended but carries "Not For New Designs" product status. While electrical equivalence is maintained at the 200 V / 3 A rating, this device exhibits higher forward voltage (1.2 V versus 900 mV) and standard recovery characteristics (>500 ns versus 40 ns fast recovery). The maximum operating temperature is limited to 150°C. This substitute is suitable only for legacy design support or applications where performance trade-offs are acceptable and new design qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can ESH3D-E3/57T be used as a direct replacement for ESH3D-M3/57T?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications: 200 V reverse voltage, 3 A average rectified current, 900 mV forward voltage at 3 A, and 40 ns reverse recovery time. Both are Active product status and operate across -55°C to 175°C. The primary difference is packaging format (Tape & Reel for both), making this a direct parametric equivalent.

Q: What is the difference between ESH3DHE3_A/H and the main part?

A: The ESH3DHE3_A/H is electrically equivalent but supplied in Cut Tape packaging instead of Tape & Reel. This part carries automotive grade classification with AEC-Q101 qualification. Selection depends on packaging requirements and whether automotive qualification is necessary for the application.

Q: Why is S3D-TP marked "Not For New Designs"?

A: The S3D-TP product status indicates this part is in mature or end-of-life phase and is not recommended for new design implementations. While electrical equivalence exists at the 200 V / 3 A rating, the device exhibits higher forward voltage (1.2 V) and slower recovery characteristics (standard recovery >500 ns). This part is suitable only for legacy system support or replacement applications.

Q: What are the key electrical differences between S3D-TP and ESH3D-M3/57T?

A: The S3D-TP exhibits three notable differences: (1) Forward voltage is 1.2 V at 3 A compared to 900 mV, resulting in higher power dissipation; (2) Recovery speed is standard (>500 ns) versus fast recovery (40 ns), affecting switching performance; (3) Reverse leakage current is 10 µA versus 5 µA at 200 V. Maximum operating temperature is also limited to 150°C versus 175°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts—ESH3D-E3/57T, ESH3DHE3_A/H, and S3D-TP—are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part ESH3D-M3/57T.

Q: What packaging formats are available for these diodes?

A: ESH3D-M3/57T and ESH3D-E3/57T are supplied in Tape & Reel (TR) format. ESH3DHE3_A/H is supplied in Cut Tape (CT) format. S3D-TP is supplied in Tape & Reel format. All parts use the same DO-214AB (SMC) package case.

Q: Can I use ESH3DHE3_A/H in a non-automotive application?

A: Yes. The ESH3DHE3_A/H meets all electrical and mechanical requirements for general-purpose applications. The automotive grade and AEC-Q101 qualification are additional certifications that do not restrict use in non-automotive designs. This part is suitable for any application requiring the specified electrical parameters.
