P4SMA15CA-M3/61 Equivalent & Substitute Parts

Part Overview

The P4SMA15CA-M3/61 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 P4SMA15CA-M3/61 are qualified based on the following critical electrical and mechanical parameters:

• Voltage - Reverse Standoff (Typ): 12.8V
• Voltage - Breakdown (Min): 14.3V
• Voltage - Clamping (Max) @ Ipp: 21.2V
• Current - Peak Pulse (10/1000µs): 18.9A minimum
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Product Status: Active

Parts meeting these electrical specifications and physical package requirements are classified as direct substitutes. Variations in manufacturer, packaging designation (Tape & Reel variants), and minor parameter tolerances within the specified ranges do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts listed maintain active product status and meet RoHS compliance requirements. The P4SMA15CA-E3/61 (Vishay) is a direct equivalent with identical electrical specifications and operating temperature range. The P4SMA15CA (Eaton) meets all critical electrical parameters with a marginally higher peak pulse current rating (19.3A versus 18.9A) and operates within a narrower temperature range (-55°C to 150°C versus -65°C to 150°C). Selection between these substitutes should be based on procurement availability, supply chain requirements, and application-specific temperature operating conditions.

Frequently Asked Questions (FAQ)

Q: Can P4SMA15CA-E3/61 be used as a direct replacement for P4SMA15CA-M3/61?

A: Yes. Both parts are manufactured by Vishay and share identical electrical specifications, package type (DO-214AC, SMA), and operating temperature range (-65°C ~ 150°C). The difference in packaging designation (M3/61 versus E3/61) reflects Tape & Reel variant coding and does not affect electrical performance or physical compatibility.

Q: Is the Eaton P4SMA15CA suitable for applications requiring the full -65°C lower temperature limit?

A: The Eaton P4SMA15CA operates from -55°C to 150°C, which does not extend to the -65°C lower limit of the Vishay variants. Applications requiring operation below -55°C must use P4SMA15CA-M3/61 or P4SMA15CA-E3/61.

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

A: Yes. All three parts use the DO-214AC (SMA) package and are surface mount components with identical physical dimensions and pin configuration.

Q: What is the significance of the higher peak pulse current in the Eaton part?

A: The Eaton P4SMA15CA specifies 19.3A peak pulse current compared to 18.9A for the Vishay variants. This represents a performance margin and does not prevent substitution; the part remains suitable for applications designed around the 18.9A specification.

Q: Do all parts meet the same compliance standards?

A: All three parts are RoHS compliant with unlimited moisture sensitivity rating (MSL 1). The Vishay parts carry ROHS3 certification, while the Eaton part carries RoHS certification. Both certifications satisfy RoHS compliance requirements.
