P4SMA170CA-M3/61 Equivalent & Substitute Parts

Part Overview

The P4SMA170CA-M3/61 is a bidirectional Transient Voltage Suppressor (TVS) diode from Vishay General Semiconductor - Diodes Division, designed for general-purpose transient protection applications. This surface-mount component operates with a reverse standoff voltage of 145V and provides clamping at 234V maximum, making it suitable for protecting sensitive circuits from voltage transients. The part is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging options are required, or when sourcing from different inventory channels is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA170CA-M3/61 is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 145V
• Voltage - Breakdown (Min): 162V
• Voltage - Clamping (Max) @ Ipp: 234V
• Current - Peak Pulse (10/1000µs): 1.3A
• Power - Peak Pulse: 300W
• Operating Temperature Range: -65°C to 150°C (TJ)
• Package / Case: DO-214AC (SMA)
• Mounting Type: Surface Mount
• Bidirectional Channels: 1
• Type: Zener

The substitute part P4SMA170CA-E3/61 meets all these criteria identically. The difference between the main part and substitute lies only in the packaging designation suffix (M3 versus E3), which reflects different tape and reel configurations from the same manufacturer. Both parts are manufactured by Vishay General Semiconductor - Diodes Division and belong to the P4SMA TransZorb® series.

Parameter Comparison

Engineering Selection Recommendations

Both the P4SMA170CA-M3/61 and P4SMA170CA-E3/61 are functionally and electrically identical, with full compatibility for direct substitution in circuit applications. Selection between these parts should be based on:

• Availability: The P4SMA170CA-E3/61 currently has higher inventory (9,777 pcs) compared to the P4SMA170CA-M3/61 (991 pcs), making it the preferred choice for immediate procurement needs.
• Tape and Reel Configuration: The suffix designations (M3 versus E3) indicate different tape and reel specifications from Vishay. Verify your assembly equipment compatibility with the specific reel configuration before final selection.
• Compliance Requirements: Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL 1 rating, ensuring no regulatory or environmental concerns with either selection.
• Long-term Sourcing: Both parts carry active product status from Vishay, indicating continued manufacturing support and availability.

Frequently Asked Questions (FAQ)

Q: Can P4SMA170CA-E3/61 be used as a direct replacement for P4SMA170CA-M3/61?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The only difference is the tape and reel configuration designation (M3 versus E3). Direct substitution is valid provided your assembly equipment supports the E3 reel specification.

Q: What does the suffix difference (M3 versus E3) mean?

A: The suffix designates the tape and reel packaging configuration used by Vishay for automated assembly. M3 and E3 represent different reel specifications. Verify your pick-and-place equipment compatibility with the specific reel type before ordering.

Q: Are there any performance differences between these parts?

A: No. All electrical characteristics, thermal ratings, and mechanical specifications are identical. Both parts provide the same 145V reverse standoff voltage, 234V clamping voltage, and 1.3A peak pulse current.

Q: Do both parts meet the same compliance standards?

A: Yes. Both P4SMA170CA-M3/61 and P4SMA170CA-E3/61 are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should I select for new designs?

A: Either part is suitable for new designs. Selection should be based on inventory availability, reel configuration compatibility with your assembly process, and supplier lead times. Both maintain active product status with Vishay.

Q: Can these parts be mixed in the same production batch?

A: Electrically yes, but verify that your assembly equipment can handle both M3 and E3 reel configurations. Mixing different reel types may require equipment reconfiguration between production runs.
