Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA6.0A BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 6V
• Voltage - Breakdown (Min): 6.67V
• Voltage - Clamping (Max) @ Ipp: 10.3V
• Current - Peak Pulse (10/1000µs): 38.8A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Unidirectional Channels: 1
• Operating Temperature Range: -55°C to 150°C (TJ)

The SMAJ6.0A-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, making it a direct functional equivalent for the obsolete P4SMA6.0A BK.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ6.0A-13-F is the qualified substitute for the obsolete P4SMA6.0A BK. This substitution is supported by:

• Identical electrical specifications across all critical voltage and current parameters
• Matching package and mounting configuration (DO-214AC, SMA)
• Active product status with established supply availability
• RoHS3 compliance and REACH unaffected status, meeting modern regulatory requirements
• Equivalent moisture sensitivity classification and export control designation

The substitute component maintains full functional compatibility with existing circuit designs without requiring layout or schematic modifications.

Frequently Asked Questions (FAQ)

Q: Can the SMAJ6.0A-13-F be used as a direct replacement for the P4SMA6.0A BK?
