P4SMA13CA-M3/5A Equivalent & Substitute Parts

Part Overview

The P4SMA13CA-M3/5A is a transient voltage suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This surface mount component operates as a bidirectional Zener diode in the DO-214AC (SMA) package, designed for general-purpose transient voltage suppression applications. The part is currently active in production 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 P4SMA13CA-M3/5A are qualified based on the following electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 11.1V
• Voltage - Breakdown (Min): 12.4V
• Voltage - Clamping (Max) @ Ipp: 18.2V
• Current - Peak Pulse (10/1000µs): 22A minimum
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Type: Zener, Bidirectional

Parts meeting these electrical specifications and physical package requirements are classified as direct substitutes. Variations in peak pulse current within the specified range, packaging tape format, and manufacturer source do not affect functional equivalence for this application category.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed are active products with full compliance certifications. Selection between P4SMA13CA-M3/5A, P4SMA13CA-E3/61, and P4SMA13CA should be based on:

• Inventory availability and lead time requirements
• Manufacturer preference or qualification requirements
• Operating temperature range: The Eaton P4SMA13CA operates from -55°C minimum, compared to -65°C for Vishay variants. Applications requiring operation below -55°C require the Vishay parts.
• Peak pulse current: The Eaton P4SMA13CA provides 22.5A peak pulse current versus 22A for Vishay variants. Both meet the 22A minimum specification.
• RoHS compliance: All parts meet RoHS requirements; Vishay parts carry ROHS3 certification while Eaton carries RoHS certification.

Frequently Asked Questions (FAQ)

Q: Can P4SMA13CA-E3/61 replace P4SMA13CA-M3/5A in all applications?

A: Yes. Both parts share identical electrical specifications (11.1V standoff, 12.4V breakdown, 18.2V clamping, 22A peak pulse, 400W power rating) and identical package geometry (DO-214AC, SMA). The difference in tape format (E3/61 versus M3/5A) affects only packaging and handling, not electrical performance or PCB compatibility.

Q: What is the difference between Vishay and Eaton P4SMA13CA variants?

A: The primary differences are: (1) Operating temperature minimum: Eaton -55°C versus Vishay -65°C; (2) Peak pulse current: Eaton 22.5A versus Vishay 22A; (3) Manufacturer source and compliance certification level. All other electrical and mechanical parameters are identical. Selection depends on temperature range requirements and manufacturer qualification.

Q: Are these parts pin-compatible?

A: Yes. All three parts use the DO-214AC (SMA) surface mount package with identical pin configuration and footprint. Direct PCB substitution is possible without layout modification.

Q: Does tape format affect electrical performance?

A: No. Tape format designations (M3/5A, E3/61) specify packaging and reel configuration only. Electrical characteristics, performance, and reliability are unaffected by tape format.

Q: Which part should be selected for low-temperature applications below -55°C?

A: Applications requiring operation below -55°C must use either P4SMA13CA-M3/5A or P4SMA13CA-E3/61 (both Vishay), which are rated to -65°C. The Eaton P4SMA13CA is limited to -55°C minimum.
