Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1.5SMC10A-M3/9AT are identified based on the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Voltage - Reverse Standoff (Typ): 8.5V to 8.55V
• Voltage - Clamping (Max) @ Ipp: 14.4V to 14.5V
• Current - Peak Pulse (10/1000µs): Minimum 103A
• Package / Case: DO-214AB, SMC surface mount
• Type: Unidirectional Zener TVS Diode
• RoHS Status: ROHS3 Compliant

Substitution Groups:

Group 1 - Direct Equivalent (Vishay Manufacturer): 1.5SMC10A-E3/57T maintains identical electrical specifications and series designation with the main part, differing only in packaging configuration (Tape & Reel variant).

Group 2 - Cross-Manufacturer Equivalent (Taiwan Semiconductor Corporation): 1.5SMC10A (TSC) provides matching voltage and power ratings with a minor increase in peak pulse current (108A vs 103A), maintaining the same base product number and electrical performance envelope.

Group 3 - Voltage-Compatible Substitutes (EVVO Semi & Alpha & Omega Semiconductor): SMCJ8.5A and SMDJ8.5A operate at 8.5V reverse standoff voltage with 14.4V clamping voltage, representing a 0.05V tolerance variation within acceptable engineering margins. SMDJ8.5A provides higher peak pulse power (3000W vs 1500W) for applications requiring enhanced transient suppression capability.

Parameter Comparison

Engineering Selection Recommendations

1.5SMC10A-E3/57T (Vishay): Direct equivalent with identical electrical specifications. Recommended as primary substitute when Vishay sourcing is required. Packaging configuration differs (Tape & Reel variant) but maintains full electrical and mechanical compatibility. ROHS3 compliant with MSL 1 rating.

1.5SMC10A (Taiwan Semiconductor Corporation): Cross-manufacturer equivalent with matching voltage ratings and base product number. Peak pulse current specification (108A) exceeds minimum requirement by 5A. Operating temperature range reduced to -55°C minimum (vs -65°C for main part). ROHS3 compliant with MSL 1 rating. Suitable for applications not requiring extended low-temperature operation below -55°C.

SMCJ8.5A (EVVO Semi): Voltage-compatible substitute with 8.5V reverse standoff (0.05V below main part specification). Clamping voltage 14.4V (0.1V below main part). Peak pulse current 104.2A meets or exceeds requirement. Operating temperature -55 to 150°C. ROHS3 compliant with MSL 1 rating. Packaging configuration: Cut Tape & Digi-Reel.

SMDJ8.5A (Alpha & Omega Semiconductor): Voltage-compatible substitute with enhanced power dissipation capability (3000W vs 1500W). Suitable for applications requiring higher transient energy absorption. Peak pulse current 208.4A significantly exceeds requirement. Operating temperature -55 to 150°C. ROHS3 compliant. Moisture sensitivity level not specified in provided data.

Frequently Asked Questions (FAQ)

Q: Can 1.5SMC10A-E3/57T be used as a direct replacement for 1.5SMC10A-M3/9AT?

A: Yes. Both parts are manufactured by Vishay with identical electrical specifications (8.55V reverse standoff, 14.5V clamping voltage, 103A peak pulse current, 1500W power rating). The difference is packaging configuration (Tape & Reel variant). Both are ROHS3 compliant with MSL 1 rating and -65 to 150°C operating temperature range.

Q: What is the difference between the Vishay 1.5SMC10A-M3/9AT and the Taiwan Semiconductor 1.5SMC10A?

A: Both maintain identical voltage specifications (8.55V reverse standoff, 14.5V clamping). The TSC version has slightly higher peak pulse current (108A vs 103A) and a reduced operating temperature minimum of -55°C instead of -65°C. Both are ROHS3 compliant with MSL 1 rating.

Q: Can SMCJ8.5A or SMDJ8.5A be used instead of the main part?

A: SMCJ8.5A and SMDJ8.5A are voltage-compatible substitutes with 8.5V reverse standoff (0.05V tolerance variation) and 14.4V clamping voltage (0.1V tolerance variation). Both meet or exceed the 103A peak pulse current requirement. SMDJ8.5A provides double the power dissipation (3000W vs 1500W). These substitutes are suitable for applications where the voltage tolerance variation is acceptable within circuit design margins.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (1.5SMC10A-E3/57T, 1.5SMC10A from TSC, SMCJ8.5A, and SMDJ8.5A) are ROHS3 compliant. Moisture sensitivity level is MSL 1 (Unlimited) for all parts except SMDJ8.5A, which does not specify MSL in the provided data.

Q: What is the operating temperature difference between the main part and substitutes?

A: The main part 1.5SMC10A-M3/9AT operates from -65°C to 150°C. The Vishay substitute 1.5SMC10A-E3/57T maintains this range. Cross-manufacturer substitutes (TSC 1.5SMC10A, EVVO SMCJ8.5A, and AOS SMDJ8.5A) operate from -55°C to 150°C, with a 10°C higher minimum temperature limit.

Q: Which substitute offers the highest transient suppression capability?

A: SMDJ8.5A from Alpha & Omega Semiconductor provides the highest peak pulse power rating at 3000W (double the main part's 1500W) with peak pulse current of 208.4A. This part is suitable for applications requiring enhanced transient energy absorption capability.

Q: Can packaging configuration affect substitution compatibility?

A: All substitute parts use the same DO-214AB (SMC) surface mount package as the main part, ensuring mechanical and PCB layout compatibility. Packaging configuration variants (Tape & Reel vs Cut Tape & Digi-Reel) affect supply and handling but do not impact electrical performance or board-level compatibility.
