Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SMCG36A-M3/9AT is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 36V (Typ), breakdown voltage minimum of 40V, and clamping voltage maximum of 58.1V at peak pulse current
• Current Handling: Peak pulse current of 25.8A at 10/1000µs pulse duration
• Power Dissipation: Peak pulse power rating of 1500W
• Package Configuration: DO-215AB surface-mount package with SMC Gull Wing footprint
• Electrical Type: Unidirectional Zener TVS diode with single channel
• Compliance: ROHS3 compliance and MSL Level 1 rating

The substitute part SMCG36A-E3/57T meets all these criteria identically, differing only in the tape and reel configuration code (E3/57T versus M3/9AT), which represents different packaging and supplier logistics parameters that do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCG36A-M3/9AT and SMCG36A-E3/57T are active production components from Vishay General Semiconductor - Diodes Division with identical electrical and mechanical specifications. Selection between these parts should be based on:

• Supply Availability: The SMCG36A-E3/57T maintains higher inventory levels (2391 Pcs) compared to the SMCG36A-M3/9AT (739 Pcs), making it preferable for high-volume procurement or extended lead-time mitigation.
• Compliance Requirements: Both parts meet ROHS3 compliance and carry MSL Level 1 rating, suitable for unrestricted moisture exposure environments.
• Packaging Configuration: The difference between M3/9AT and E3/57T designations reflects supplier-specific tape and reel configurations. Verify compatibility with your assembly equipment's tape specifications before final selection.

Frequently Asked Questions (FAQ)

Q: Can SMCG36A-E3/57T be used as a direct replacement for SMCG36A-M3/9AT in production?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the tape and reel configuration code. Confirm that your pick-and-place equipment is compatible with the E3/57T tape specification before implementation.

Q: What do the suffixes M3/9AT and E3/57T represent?

A: These suffixes denote Vishay's internal tape and reel packaging configurations, including reel size, tape width, and quantity per reel. They do not affect the electrical performance or physical footprint of the diode itself.

Q: Are there any temperature or compliance differences between these parts?

A: No. Both parts operate across the identical temperature range (-55°C to 150°C junction temperature) and carry the same ROHS3 and MSL Level 1 certifications.

Q: What is the DO-215AB package footprint compatibility?

A: Both parts use the DO-215AB surface-mount package with SMC Gull Wing configuration. PCB footprints and reflow profiles are identical between the two part numbers.

Q: Which part should I specify for new designs?

A: Either part is acceptable for new designs. Consider SMCG36A-E3/57T if supply chain continuity is a priority, given its higher current inventory level.
