P4SMA100A-M3/5A Equivalent & Substitute Parts

Part Overview

The P4SMA100A-M3/5A is an active Transient Voltage Suppressor (TVS) diode manufactured by Vishay General Semiconductor - Diodes Division. This unidirectional zener diode operates in the P4SMA series and is designed for general-purpose transient voltage suppression applications. The component is housed in a DO-214AC (SMA) surface mount package and is ROHS3 compliant. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, optimize inventory management, and maintain design continuity when the primary part number becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA100A-M3/5A is determined by strict equivalence across the following critical parameters:

• Voltage ratings: Reverse standoff voltage of 85.5V (typical), breakdown voltage minimum of 95V, and clamping voltage maximum of 137V at peak pulse current
• Electrical performance: Peak pulse current of 2.2A at 10/1000µs pulse duration and peak pulse power of 300W
• Package specification: DO-214AC (SMA) surface mount package
• Thermal range: Operating temperature from -65°C to 150°C (junction temperature)
• Compliance: ROHS3 compliance and MSL rating of 1

The P4SMA100A-E3/61 meets all these criteria and is classified as a direct manufacturer equivalent within the same P4SMA series from Vishay.

Parameter Comparison

Engineering Selection Recommendations

Both the P4SMA100A-M3/5A and P4SMA100A-E3/61 are active products from Vishay with identical electrical and mechanical specifications. Selection between these parts should be based on availability and supply chain requirements. Both parts maintain ROHS3 compliance and MSL rating of 1, ensuring compatibility with standard manufacturing and storage conditions. The P4SMA100A-E3/61 offers higher inventory availability (4311 pieces in stock versus 699 pieces), making it a practical alternative when supply constraints exist.

Frequently Asked Questions (FAQ)

Q: Can the P4SMA100A-E3/61 be used as a direct replacement for the P4SMA100A-M3/5A?

A: Yes. Both parts are identical in electrical performance, voltage ratings, current handling, thermal range, and package specification. They are interchangeable at the circuit level.

Q: Are there any differences in the DO-214AC (SMA) package between these parts?

A: No. Both parts use the identical DO-214AC (SMA) surface mount package, ensuring mechanical and thermal compatibility on PCBs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the P4SMA100A-M3/5A and P4SMA100A-E3/61 are ROHS3 compliant with MSL rating of 1 (unlimited moisture sensitivity level), meeting identical regulatory and environmental requirements.

Q: What is the significance of the different suffixes (-M3/5A versus -E3/61)?

A: The suffixes indicate different packaging configurations or tape specifications from Vishay. The electrical and mechanical specifications remain identical, with differences limited to packaging and distribution formats.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -65°C to 150°C (junction temperature), ensuring equivalent thermal performance in all specified operating conditions.
