Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA150A BK is determined by strict equivalence across the following critical parameters:

• Voltage - Reverse Standoff (Typ): 150V
• Voltage - Breakdown (Min): 167V
• Voltage - Clamping (Max) @ Ipp: 243V
• Current - Peak Pulse (10/1000µs): 1.6A
• Power - Peak Pulse: 400W
• Unidirectional Channels: 1
• Package / Case: DO-214AC, SMA
• Operating Temperature Range: -55°C ~ 150°C (TJ)

The SMAJ150A-13-F from Diodes Incorporated meets all specified electrical and mechanical parameters, making it a direct functional equivalent for the obsolete P4SMA150A BK.

Parameter Comparison

Engineering Selection Recommendations

The SMAJ150A-13-F is the appropriate substitute for the obsolete P4SMA150A BK based on the following factors:

All electrical parameters match exactly: 150V reverse standoff voltage, 167V minimum breakdown voltage, 243V maximum clamping voltage, 1.6A peak pulse current, and 400W peak pulse power dissipation.

The mechanical specifications are identical: both components use the DO-214AC SMA surface mount package with equivalent moisture sensitivity ratings.

The SMAJ150A-13-F maintains the same operating temperature range of -55°C to 150°C (TJ), ensuring thermal compatibility in existing designs.

The substitute part is manufactured by Diodes Incorporated with active product status, ensuring long-term availability and supply chain continuity. The SMAJ150A-13-F is ROHS3 compliant, meeting current environmental and regulatory requirements.
