Product details
Overview
PDZ24BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage of 24 V at 5 mA, ±2 % tolerance (B-series), 120 Ω maximum differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ24BGWJ datasheet, PDZ24BGWJ pinout, PDZ24BGWJ application, or PDZ24BGWJ equivalent, this device serves as a stable, surface-mount voltage clamp in power supply feedback loops, overvoltage protection circuits, and low-power reference designs where tight voltage tolerance and thermal reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 23.72 V (min) to 24.78 V (max) at IZ = 5 mA, exhibiting a temperature coefficient of +19.0 mV/K (typ) and +20.4 mV/K (max), enabling predictable drift compensation in regulated systems.
Its non-repetitive peak reverse current capability is 1.3 A (tp = 100 μs), supported by 40 W surge power rating and 365 mW steady-state total power dissipation on standard FR4 PCB - confirming suitability for transient suppression in 12 V/24 V automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 23.72 V to 24.78 V at IZ = 5 mA - defines precise clamping threshold for 24 V rail stabilization |
| Tolerance | ±2 % (B-series) - ensures consistent voltage reference across production batches without calibration |
| Differential Resistance rdif | ≤120 Ω - maintains low dynamic impedance for stable regulation under varying load currents |
| Reverse Current IR | ≤0.05 μA at VR = 19.0 V - guarantees minimal leakage in high-impedance bias networks |
| Thermal Resistance Rth(j-a) | 340 K/W in free air - enables thermal-aware layout with standard SMD footprint on single-sided FR4 |
| Surge Capability IZSM | 1.3 A (100 μs pulse) - supports transient immunity in automotive load-dump and ISO 7637-2 compliant designs |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per AEC standard |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C24 | ±5 % tolerance, 200 mW Ptot, SOT23 package | Higher voltage drift and lower surge rating; suitable only for non-automotive consumer designs | Select when cost sensitivity outweighs precision and AEC-Q101 compliance |
| MMSZ5242B | ±5 % tolerance, 500 mW Ptot, SOD123 package, no AEC-Q101 | Higher power but unqualified for automotive; higher leakage (>1 μA at 19 V) | Choose for industrial power supplies requiring higher steady-state dissipation without automotive validation |
Compared with BZX84-C24 and MMSZ5242B, PDZ24BGWJ delivers tighter tolerance, lower leakage, and automotive qualification - making it the sole choice for safety-critical 24 V reference nodes where long-term stability and regulatory compliance are mandatory.

FAQ
What is the maximum continuous reverse current for PDZ24BGWJ at 25 °C ambient?
The maximum continuous reverse current is determined by the 365 mW total power dissipation limit. At nominal 24 V Zener voltage, this corresponds to approximately 15.2 mA (365 mW ÷ 24 V). Operation beyond this requires derating per thermal resistance data and PCB copper area.
Does PDZ24BGWJ support reflow soldering only, or can it be hand-soldered?
Nexperia specifies reflow soldering as the only recommended method. Hand-soldering is not advised due to thermal stress risks - the SOD123 package's small mass and internal bond wire sensitivity require controlled ramp rates and peak temperatures per J-STD-020 profile for Class 3 reliability.
How does the +19.0 mV/K temperature coefficient affect circuit performance?
This positive coefficient means output voltage increases ~19 mV per °C rise in junction temperature. In feedback loops, it introduces predictable upward drift - useful for compensating negative-drift components (e.g., op-amp input offsets) but requires thermal layout awareness to avoid instability in closed-loop regulation.
Is PDZ24BGWJ suitable for bidirectional ESD protection?
No - PDZ24BGWJ is a unidirectional Zener diode rated only for reverse-bias clamping. It lacks symmetric breakdown characteristics or specified ESD ratings (e.g., IEC 61000-4-2). For bidirectional protection, purpose-built TVS diodes like PESD5V0S1BA should be used instead.
