PDZ24B-QF Equivalent & Substitute Parts

Part Overview

The PDZ24B-QF is a 24 V Zener diode manufactured by Nexperia USA Inc., designed for surface mount applications in the SOD-323 package. This component operates at a maximum power dissipation of 400 mW with a nominal Zener voltage of 24 V and ±2% tolerance. The part is classified as Active and carries AEC-Q101 automotive qualification, making it suitable for automotive-grade circuit protection and voltage regulation applications. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable or when alternative sourcing options are required to maintain supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ24B-QF is determined by strict equivalence across the following critical parameters:

• Zener Voltage (Vz): 24 V nominal
• Voltage Tolerance: ±2%
• Maximum Power Dissipation: 400 mW
• Impedance (Zzt): 30 Ohms maximum
• Reverse Leakage Current: 50 nA @ 19 V
• Forward Voltage (Vf): 1.1 V maximum @ 100 mA
• Operating Temperature: 150°C junction temperature
• Package Type: SOD-323 (SC-76)
• Mounting Configuration: Surface Mount
• Compliance Standards: ROHS3, AEC-Q101 Automotive Grade

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes. The PDZ24B,115 meets all specified parameters and is therefore a valid substitute for the PDZ24B-QF.
