PDZ22B-QF Equivalent & Substitute Parts Reference

Part Overview

The PDZ22B-QF from Nexperia USA Inc. is an automotive grade Zener diode designed for surface mount applications. It features a Zener voltage of 22 V, maximum power dissipation of 400 mW, and high reliability with AEC-Q101 qualification. The product status is active, and it is supplied in the SOD-323 (SC-76) package. Finding alternative models is necessary to ensure supply chain continuity and design flexibility, especially when managing inventory or qualifying additional approved sources for the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts are determined strictly by matching key parameters relevant to Zener diode selection. The following criteria are used:

Zener Voltage (Nom) (Vz)
Tolerance
Maximum Power (Pmax)
Impedance (Max) (Zzt)
Reverse Leakage Current @ Vr
Forward Voltage (Vf) (Max) @ If
Operating Temperature
Mounting Type
Package / Case
Product Status
Compliance (RoHS, REACH)
Moisture Sensitivity Level (MSL)
Supplier Device Package

Parts meeting all these parameters are considered electrical and mechanical equivalents within the diodes, Zener category.
