Key Parameters

Substitute Part Grouping Explanation

Substitution of the P4SMA150A TR13 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: Reverse standoff voltage of 150V, breakdown minimum of 167V, and maximum clamping voltage of 243V must be identical
• Current Handling: Peak pulse current of 1.6A (10/1000µs pulse) and peak pulse power of 400W must match
• Package Configuration: Surface mount DO-214AC (SMA) package is mandatory for mechanical and thermal compatibility
• Electrical Type: Unidirectional Zener TVS diode with single channel configuration
• Temperature Range: Operating temperature range of -55°C to 150°C (TJ) must be maintained
• Moisture Sensitivity: MSL 1 (Unlimited) classification ensures handling compatibility

The SMAJ150A-13-F from Diodes Incorporated meets all these criteria and is classified as an active product, providing direct functional and mechanical equivalence.
