Product details
Overview
PDZ8.2BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection in low-power circuits. It delivers a nominal Zener voltage of 8.2 V at 5 mA, ±2 % tolerance (B-series), 60 Ω maximum differential resistance, 0.5 μA reverse current at 6.2 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ8.2BGW datasheet, PDZ8.2BGW pinout, PDZ8.2BGW application, or PDZ8.2BGW equivalent, this device is selected for stable reference generation in power supply feedback loops, ESD clamp networks, and biasing circuits where tight voltage tolerance, low thermal drift, and surface-mount compatibility are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 8.02–8.36 V at IZ = 5 mA, exhibiting a temperature coefficient of +4.6 mV/K - indicating positive drift with junction temperature rise. Its low 60 Ω dynamic impedance ensures minimal output voltage variation under load changes.
The device supports non-repetitive surge handling up to 3.5 A peak reverse current (100 μs pulse) and dissipates up to 365 mW continuously at Tamb ≤ 25 °C on standard FR4 PCB. Thermal resistance from junction to solder point is 50 K/W, enabling effective heat transfer through the cathode pad.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2 | Same 8.2 V nominal, ±5 % tolerance, SOT23 package, higher 90 Ω rdif | Less precise regulation; unsuitable for <±3 % output accuracy requirements | Select when cost sensitivity outweighs voltage stability needs and SOT23 footprint is preferred |
| MMSZ5235B | 8.2 V nominal, ±5 % tolerance, SOD123 package, 100 Ω rdif, no AEC-Q101 | Lacks automotive qualification; higher impedance reduces regulation fidelity | Use only in commercial-grade consumer products where qualification and low rdif are not mandatory |
Compared with BZX84-C8V2 and MMSZ5235B, PDZ8.2BGW offers tighter ±2 % tolerance, lower 60 Ω impedance, and AEC-Q101 qualification - making it the sole choice for automotive and high-accuracy industrial regulation where long-term stability and environmental robustness are critical.

FAQ
What is the maximum continuous power dissipation for PDZ8.2BGW at 70 °C ambient?
At Tamb = 70 °C, derating applies linearly from 365 mW at 25 °C using the thermal resistance Rth(j-a) of 340 K/W. The maximum allowable Ptot is 365 mW − ((70−25) × 365/125) ≈ 234 mW. This ensures junction temperature remains below 150 °C under steady-state conditions.
Is PDZ8.2BGW suitable for bidirectional ESD protection?
No - PDZ8.2BGW is a unidirectional Zener diode configured for reverse-bias operation only. Its forward voltage is 0.9 V at 10 mA, but it lacks symmetrical clamping capability. For bidirectional protection, paired Zeners or dedicated TVS diodes like PESD5V0S1BA must be used.
How does the +4.6 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
Over this 165 K range, the total voltage shift is +4.6 mV/K × 165 K ≈ +759 mV. At nominal 8.2 V, this represents ~9.3 % drift. Designers must account for this in systems requiring tight regulation across full temperature range - often by compensating with negative-coefficient components or using closed-loop feedback.
Can PDZ8.2BGW replace PDZ8.2B in existing designs?
Yes - PDZ8.2BGW is the enhanced, AEC-Q101 qualified version of PDZ8.2B, sharing identical electrical specifications, SOD123 package, pinout, and marking (BE). The "GW" suffix denotes automotive qualification and improved robustness; no layout or schematic changes are needed for drop-in replacement.
