Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N4732A_S00Z is determined by strict equivalence across the following electrical and mechanical parameters:

Zener voltage nominal rating of 4.7 V with ±5% tolerance ensures voltage regulation performance within the original design specification. Maximum power dissipation of 1 W establishes thermal and current handling capacity. Maximum impedance of 8 Ohms defines dynamic resistance characteristics. Reverse leakage current of 10 µA at 1 V establishes reverse bias performance. Through-hole mounting type and DO-41 package configuration ensure mechanical and electrical interface compatibility with existing printed circuit board layouts and assembly processes.

The 1N4732A manufactured by Microchip Technology meets all specified electrical parameters and maintains identical package configuration, establishing direct substitution capability.
