Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA5.0CA BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff: 5V (nominal)
• Voltage - Breakdown: 6.4V (minimum)
• Voltage - Clamping: 9.2V (maximum at Ipp)
• Current - Peak Pulse: 44.6A (10/1000µs)
• Power - Peak Pulse: 400W
• Package: DO-214AC, SMA (surface mount)
• Bidirectional Channels: 1
• Operating Temperature Range: -55°C ~ 150°C

The SMAJ5.0CA-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, providing direct functional equivalence for the obsolete P4SMA5.0CA BK.
