P4SMA100A-M3/61 Equivalent & Substitute Parts

Part Overview

The P4SMA100A-M3/61 is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates in the DO-214AC (SMA) package and is designed for general purpose transient voltage suppression applications. The part is currently active in production status with full RoHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA100A-M3/61 are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution logic is based on the following critical parameters:

• Voltage - Reverse Standoff (Typ): 85.5V
• Voltage - Breakdown (Min): 95V
• Voltage - Clamping (Max) @ Ipp: 137V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

Parts are grouped into two categories: direct manufacturer equivalents (identical specifications and packaging) and manufacturer-recommended alternatives (compatible electrical performance with allowable parameter variations within the same product series).

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet applicable regulatory compliance requirements. The P4SMA100A-E3/61 (Vishay) is a direct equivalent to the P4SMA100A-M3/61, differing only in packaging designation (E3/61 versus M3/61 tape and reel configuration). Both Vishay parts are RoHS3 compliant and operate across the full temperature range of -65°C to 150°C.

The P4SMA100A (Eaton) is a manufacturer-recommended alternative that maintains identical voltage specifications and clamping characteristics. This part features higher peak pulse current (3A versus 2.2A) and peak pulse power (400W versus 300W), providing enhanced transient suppression capability. The Eaton part operates across a narrower temperature range (-55°C to 150°C) and carries RoHS compliance certification. Selection between these parts depends on supply availability, procurement lead times, and application-specific thermal requirements.

Frequently Asked Questions (FAQ)

Q: Can P4SMA100A-E3/61 be used as a direct replacement for P4SMA100A-M3/61?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications, voltage ratings, and package type (DO-214AC, SMA). The designation difference (M3/61 versus E3/61) reflects tape and reel packaging configuration only and does not affect electrical performance or mechanical compatibility.

Q: What are the key differences between the Vishay P4SMA100A-M3/61 and the Eaton P4SMA100A?

A: The primary differences are manufacturer and peak pulse ratings. The Eaton part provides higher peak pulse current (3A versus 2.2A) and peak pulse power (400W versus 300W). Both maintain the same voltage specifications (85.5V standoff, 95V breakdown, 137V clamping). The Eaton part operates across a narrower temperature range (-55°C to 150°C versus -65°C to 150°C).

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-214AC (SMA) package and surface mount configuration, ensuring mechanical and footprint compatibility on standard PCB designs.

Q: Do all substitute parts meet the same compliance standards?

A: All three parts are RoHS compliant and carry unlimited moisture sensitivity rating (MSL 1). The Vishay parts are specifically RoHS3 compliant, while the Eaton part is RoHS compliant. All parts are REACH unaffected and carry EAR99 export classification.

Q: Which part should be selected for applications requiring the lowest operating temperature?

A: The Vishay parts (P4SMA100A-M3/61 and P4SMA100A-E3/61) support operation down to -65°C, compared to -55°C for the Eaton P4SMA100A. Selection depends on specific application thermal requirements.
