Substitute Part Grouping Explanation

Substitution of the P4SMA8.0A BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 8V (typ)
• Voltage - Clamping (Max) @ Ipp: 13.6V
• Current - Peak Pulse (10/1000µs): 29.4A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C to 150°C (TJ)

The substitute part SMAJ8.0A-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, ensuring direct functional compatibility in applications requiring 8V TVS protection with SMA surface-mount packaging.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can SMAJ8.0A-13-F be used as a direct replacement for P4SMA8.0A BK?

A: Yes. Both components share identical electrical specifications (8V standoff, 13.6V clamping, 29.4A peak pulse current, 400W peak power) and package configuration (DO-214AC, SMA surface mount). No circuit redesign is required.

Q: What is the primary reason for substitution?

A: The P4SMA8.0A BK is classified as obsolete. The SMAJ8.0A-13-F maintains active product status, ensuring reliable long-term availability and supply chain support.

Q: Are there packaging differences between these parts?

A: No. Both components use identical DO-214AC (SMA) surface-mount packaging. The SMAJ8.0A-13-F is supplied in Tape & Reel format, which is standard for high-volume manufacturing and assembly operations.

Q: Do compliance certifications differ?

A: The SMAJ8.0A-13-F carries RoHS3 compliance and REACH unaffected status. These certifications align with current regulatory requirements for electronic components in industrial and commercial applications.

Q: Is thermal performance equivalent?

A: Yes. Both components operate across the same temperature range (-55°C to 150°C junction temperature) with identical power dissipation ratings (400W peak pulse).
