Product details
Overview
PDZ8.2BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage 8.2 V at 5 mA, ±2 % tolerance (B-series), 60 Ω max differential resistance, and 0.5 μA max reverse current at 6.6 V. It supports automotive-grade reliability per AEC-Q101 and operates across −55 °C to +150 °C ambient.
For engineers reviewing the PDZ8.2BGWX datasheet, PDZ8.2BGWX pinout, PDZ8.2BGWX application, or PDZ8.2BGWX equivalent, this device is selected for low-drift, surface-mount voltage clamping in power supply feedback loops, overvoltage protection circuits, and analog reference generation where tight voltage accuracy and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 8.02 V (min) to 8.36 V (max) at IZ = 5 mA, exhibiting a temperature coefficient of +4.6 mV/K - indicating positive drift with junction temperature rise. Its low 60 Ω differential resistance ensures stable regulation under varying load currents.
The device delivers 365 mW total power dissipation on standard FR4 PCB (single-sided copper, tin-plated), with non-repetitive peak reverse power handling up to 40 W for 100 μs pulses. Thermal resistance from junction to solder point is 50 K/W, enabling effective heat transfer through the cathode pad.

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, 300 mW Ptot | Higher tolerance and lower power rating; not AEC-Q101 qualified | Select when cost sensitivity outweighs automotive qualification and tighter regulation needs |
| MMSZ5235B | 8.2 V nominal, ±5 %, SOD123, 500 mW Ptot, no AEC-Q101 status | Higher power but wider tolerance and unqualified for automotive use | Prefer for industrial non-automotive designs requiring higher continuous dissipation |
Compared with BZX84-C8V2 and MMSZ5235B, PDZ8.2BGWX provides superior voltage accuracy (±2 % vs. ±5 %), automotive qualification, and optimized thermal performance in SOD123 - making it the preferred choice for safety-critical or high-precision regulation where long-term stability and environmental robustness are mandatory.

FAQ
What is the maximum reverse current specification for PDZ8.2BGWX at 6.6 V?
The maximum reverse current IR is 0.5 μA at VR = 6.6 V and Tj = 25 °C. This low leakage ensures minimal parasitic loading in high-impedance reference or bias networks, critical for precision analog circuits and battery-powered systems where quiescent current must be minimized.
Is PDZ8.2BGWX suitable for reflow soldering only?
Yes - Nexperia specifies reflow soldering as the only recommended method for PDZ8.2BGWX. The SOD123 package is not rated for wave or hand soldering due to thermal stress limitations. Reflow profile must comply with JEDEC J-STD-020, with peak temperature ≤260 °C and time above 217 °C limited to 60 seconds.
How does the +4.6 mV/K temperature coefficient affect circuit design?
The positive temperature coefficient means VZ increases by ~4.6 mV per °C rise in junction temperature. In closed-loop regulators, this can offset negative tempcos of other components; in standalone references, it requires system-level compensation or calibration if operation spans >60 °C ambient range.
Can PDZ8.2BGWX replace PDZ8.2B in existing designs?
Yes - PDZ8.2BGWX is a direct replacement for PDZ8.2B, sharing identical electrical specifications, SOD123 package dimensions, pinout, and AEC-Q101 qualification. The 'X' suffix denotes tape-and-reel packaging per EIA-481 standard; no circuit or layout changes are needed for migration.
