SM6T27A-M3/52 Equivalent & Substitute Parts

Part Overview

The SM6T27A-M3/52 is a unidirectional transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the 23.1V reverse standoff voltage range with a 37.5V maximum clamping voltage and 16A peak pulse current rating. The device is designed for general-purpose transient protection applications and is currently in active production status with RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SM6T27A-M3/52 are qualified based on the following critical parameters that determine functional and mechanical compatibility:

• Voltage - Reverse Standoff (Typ): 23.1V
• Voltage - Breakdown (Min): 25.7V
• Voltage - Clamping (Max) @ Ipp: 37.5V
• Current - Peak Pulse (10/1000µs): 16A minimum
• Power - Peak Pulse: 600W
• Package / Case: DO-214AA, SMB
• Mounting Type: Surface Mount
• Type: Zener
• Unidirectional Channels: 1

All identified substitute parts maintain these electrical specifications within the allowed tolerances for the product category. Packaging format variations (Tape & Reel, Cut Tape, Bulk) do not affect electrical or mechanical compatibility and represent different supply chain configurations of the same component design.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active production status and are electrically and mechanically compatible with the SM6T27A-M3/52 based on the critical parameters provided.

P6SMB27A-E3/52 (Vishay): Direct manufacturer equivalent with identical electrical specifications and RoHS3 compliance. Packaging format differs (Cut Tape & Digi-Reel vs. Tape & Reel) but does not affect component functionality or PCB assembly compatibility.

P6SMB27A (Eaton): Functionally equivalent with 16.3A peak pulse current (exceeds 16A minimum requirement). Operating temperature range is -55 to 150°C (lower minimum than SM6T27A-M3/52 at -65°C). RoHS compliant. Suitable for applications where the -55°C minimum temperature specification is acceptable.

SZP6SMB27AT3G (onsemi): Electrically equivalent with 16A peak pulse current and -65 to 150°C operating temperature range matching the original part. Includes AEC-Q101 automotive qualification. Capacitance specification provided (700pF @ 1MHz). RoHS and REACH compliance status not specified in available data.

Frequently Asked Questions (FAQ)

Q: Can P6SMB27A-E3/52 be used as a direct replacement for SM6T27A-M3/52?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications (23.1V reverse standoff, 25.7V breakdown minimum, 37.5V clamping maximum, 16A peak pulse current, 600W peak power). The packaging format difference (Cut Tape & Digi-Reel vs. Tape & Reel) does not affect electrical performance or PCB assembly compatibility.

Q: What is the difference between the Eaton P6SMB27A and the Vishay SM6T27A-M3/52?

A: The Eaton part has a slightly higher peak pulse current rating (16.3A vs. 16A) and a higher minimum operating temperature (-55°C vs. -65°C). All other electrical parameters are identical. The Eaton part is suitable for applications where the -55°C minimum temperature is acceptable.

Q: Is the onsemi SZP6SMB27AT3G suitable for automotive applications?

A: The onsemi SZP6SMB27AT3G carries AEC-Q101 automotive qualification. If your application requires automotive-grade components, this part meets that requirement. All electrical specifications match the SM6T27A-M3/52.

Q: Do all substitute parts have the same package dimensions?

A: Yes. All substitute parts use the DO-214AA (SMB) package, which has standardized dimensions and PCB footprint compatibility. Surface mount assembly processes are identical across all listed parts.

Q: Are there any compliance differences between the substitute parts?

A: The Vishay parts (SM6T27A-M3/52 and P6SMB27A-E3/52) are ROHS3 compliant. The Eaton P6SMB27A is RoHS compliant. The onsemi SZP6SMB27AT3G compliance status is not specified in the provided data. All parts are REACH unaffected or REACH compliant based on available information.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All listed parts meet the same electrical and mechanical specifications for the 23.1V reverse standoff, 37.5V clamping voltage, and 16A peak pulse current rating. They are pin-compatible and functionally interchangeable in the DO-214AA (SMB) package.
