Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P4SMA75CA TR13 are identified based on strict electrical and mechanical parameter matching within the TVS diode category. The substitution criteria are:

• Voltage - Reverse Standoff (Typ): 75V
• Voltage - Breakdown (Min): 83.3V
• Voltage - Clamping (Max) @ Ipp: 121V
• Current - Peak Pulse (10/1000µs): 3.3A
• Power - Peak Pulse: 400W
• Package / Case: DO-214AC, SMA
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 150°C (TJ)

Parts meeting all these parameters are classified as direct electrical and mechanical equivalents suitable for replacement in the same application circuit.
