P4SMA16A-M3/5A Equivalent & Substitute Parts

Part Overview

The P4SMA16A-M3/5A 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 with full RoHS3 compliance and unlimited moisture sensitivity rating. Alternative equivalent parts may be required due to inventory availability, regional sourcing constraints, or specific packaging requirements across different manufacturing locations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the P4SMA16A-M3/5A is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 13.6V
• Voltage - Breakdown (Min): 15.2V
• Voltage - Clamping (Max) @ Ipp: 22.5V
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Type: Zener

Substitute parts must maintain identical electrical performance within these specifications. Variations in Current - Peak Pulse or Operating Temperature Range do not disqualify substitution when all voltage parameters and package specifications remain constant. All identified substitutes belong to the P4SMA series and share the same base product designation.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet regulatory compliance requirements. The P4SMA16A-E3/61 from Vishay is a direct equivalent with identical electrical specifications and temperature range, differing only in packaging designation (Tape & Reel variant). The P4SMA16A from Eaton provides functional equivalence with marginally higher peak pulse current (18.2A versus 17.8A) and a reduced lower operating temperature limit (-55°C versus -65°C). Selection between these substitutes should be based on inventory availability, supply chain requirements, and specific application temperature constraints. All parts carry unlimited moisture sensitivity rating and meet ECCN EAR99 classification.

Frequently Asked Questions (FAQ)

Q: Can P4SMA16A-E3/61 be used as a direct replacement for P4SMA16A-M3/5A?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications across all critical voltage parameters, clamping characteristics, and operating temperature range. The designation difference reflects packaging and tape configuration variants only.

Q: Is the Eaton P4SMA16A compatible with the Vishay P4SMA16A-M3/5A?

A: Yes, with application-specific considerations. The Eaton part maintains equivalent voltage performance and power rating. The operating temperature minimum is -55°C instead of -65°C, which may impact applications requiring operation below -55°C. Peak pulse current is slightly higher at 18.2A.

Q: What determines substitution eligibility for this TVS diode?

A: Substitution is determined by matching voltage parameters (reverse standoff, breakdown, and clamping voltages), package type (DO-214AC, SMA), mounting configuration (surface mount), and channel configuration (unidirectional). Current and temperature specifications may vary within acceptable ranges.

Q: Are all substitute parts RoHS compliant?

A: Yes. The Vishay parts carry ROHS3 compliance certification. The Eaton part carries RoHS compliance certification. Both meet regulatory requirements for restricted substance use.

Q: Does packaging designation affect electrical performance?

A: No. Packaging designations such as M3/5A and E3/61 indicate tape configuration and reel specifications for automated assembly. Electrical performance remains identical across these variants.
