SM5S24A-E3/2D Equivalent & Substitute Parts

Part Overview

The SM5S24A-E3/2D is a unidirectional Zener-type transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This component is designed for general-purpose transient voltage suppression applications, featuring a 24V reverse standoff voltage and 38.9V maximum clamping voltage. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SM5S24A-E3/2D is determined by the following critical parameters:

• Voltage - Reverse Standoff: 24V (nominal)
• Voltage - Breakdown (Min): 26.7V
• Voltage - Clamping (Max) @ Ipp: 38.9V
• Current - Peak Pulse (10/1000µs): 93A
• Power - Peak Pulse: 3600W
• Package / Case: DO-218AB
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C to 175°C (TJ)

The SM5S24A-TP qualifies as a direct substitute, maintaining identical electrical specifications and package configuration while differing only in manufacturer (Micro Commercial Co) and packaging format (Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

The SM5S24A-TP provides functional equivalence to the SM5S24A-E3/2D across all critical electrical and mechanical parameters. Both components maintain identical voltage suppression characteristics, peak pulse current ratings, and thermal operating ranges within the DO-218AB surface-mount package.

The SM5S24A-TP carries AEC-Q101 automotive qualification, whereas the main part does not specify this certification. For applications requiring automotive-grade components, the SM5S24A-TP is suitable. Both parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1).

Selection between these parts should be based on procurement availability, packaging requirements (the substitute is supplied in Tape & Reel format), and any specific qualification mandates within the application environment.

Frequently Asked Questions (FAQ)

Q: Can SM5S24A-TP be used as a direct replacement for SM5S24A-E3/2D?

A: Yes. Both components share identical electrical specifications (24V standoff, 26.7V breakdown minimum, 38.9V clamping maximum, 93A peak pulse current) and are packaged in DO-218AB surface-mount configuration. Substitution is electrically and mechanically valid.

Q: What is the difference between the main part and the substitute?

A: The primary differences are manufacturer (Vishay vs. Micro Commercial Co), product status (Obsolete vs. Not For New Designs), and packaging format (the substitute is supplied in Tape & Reel). The SM5S24A-TP includes AEC-Q101 automotive qualification.

Q: Are there packaging considerations when switching to SM5S24A-TP?

A: The substitute is supplied in Tape & Reel (TR) format, whereas the main part packaging is not specified. Verify that your procurement and assembly processes accommodate Tape & Reel packaging if switching suppliers.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both SM5S24A-E3/2D and SM5S24A-TP are ROHS3 compliant and carry REACH Unaffected status.

Q: What is the operating temperature range for these components?

A: Both parts operate across -55°C to 175°C junction temperature (TJ), suitable for industrial and automotive environments.
