PDZ11B-QZ Equivalent & Substitute Parts Reference

Part Overview

The PDZ11B-QZ from Nexperia USA Inc. is an automotive-grade, surface-mount Zener diode in the SC-76, SOD-323 package. It features a nominal Zener voltage of 11 V with ±2% tolerance, a maximum power dissipation of 400 mW, and specific electrical performance characteristics suitable for voltage regulation and protection applications. This product is currently Active, but finding compatible substitute parts is essential for inventory management, ongoing supply chain reliability, and ensuring design continuity when the main model is unavailable or requires alternate sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for Zener diodes in the automotive-grade category are grouped strictly based on electrical and mechanical parameters explicitly provided. The key parameters determining substitution compatibility are: Zener voltage (Nom) (Vz), tolerance, power rating, impedance (max), reverse leakage current at specified voltage, forward voltage at specified current, package/case type, mounting type, operating temperature, grade, qualification, and compliance statuses. Only parts matching these criteria are listed as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ11B-QZ and its parametric substitute PDZ11B,115 are listed as Active, automotive-grade components with AEC-Q101 qualification, ROHS3 compliance, MSL 1 (Unlimited), and REACH Unaffected status. There are no differences in electrical or mechanical parameters between the parts provided. Selection of either part is supported by equivalent compliance and inventory availability.

Frequently Asked Questions (FAQ)

Q1: What criteria determine a valid substitute for PDZ11B-QZ in Zener diode applications?
