Engineering Selection Recommendations

AS3PJHM3_A/H is a direct manufacturer equivalent with active product status. This part maintains all critical electrical parameters and automotive qualification. The primary distinction is packaging format (Tape & Reel) and forward voltage specification measured at different test conditions (1.1 V @ 3 A versus 920 mV @ 1.5 A). Both specifications are within acceptable operating margins for avalanche diode applications. This part is suitable for direct substitution in new designs and production applications.

AS3PJ-M3/86A is a parametric equivalent with active product status. This part matches the forward voltage specification exactly (920 mV @ 1.5 A) and maintains all other electrical and mechanical parameters. Packaging is Tape & Reel format. This part is suitable for direct substitution in applications requiring identical forward voltage characteristics.

AS3PJ-M3/87A is a parametric equivalent with active product status. This part matches the forward voltage specification exactly (920 mV @ 1.5 A) and maintains all other electrical and mechanical parameters. Packaging is Tape & Reel format. This part is suitable for direct substitution in applications requiring identical forward voltage characteristics.

All three substitute parts carry AEC-Q101 automotive qualification and ROHS3 compliance, ensuring compatibility with automotive and regulated applications. Selection between AS3PJHM3_A/H, AS3PJ-M3/86A, and AS3PJ-M3/87A depends on forward voltage test condition requirements and packaging format availability.

Frequently Asked Questions (FAQ)

Q: Can AS3PJHM3_A/H replace AS3PJHM3/86A in existing designs?

A: Yes. AS3PJHM3_A/H maintains all critical electrical parameters including reverse voltage (600 V), average rectified current (2.1 A), reverse recovery time (1.2 µs), and reverse leakage current (10 µA @ 600 V). The forward voltage is specified at different test conditions but remains within acceptable operating margins for avalanche diode applications. Both parts use identical TO-277A (SMPC) surface mount packaging.

Q: What is the difference between AS3PJ-M3/86A and AS3PJ-M3/87A?

A: Both parts are parametric equivalents with identical electrical specifications. The forward voltage specification is 920 mV @ 1.5 A for both parts. All other parameters including reverse voltage, current rating, recovery time, leakage current, capacitance, and temperature range are identical. Both use TO-277A (SMPC) surface mount packaging and carry AEC-Q101 qualification.
