Product details
Overview
PDZ5.1BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at 5.1 V nominal working voltage with ±2 % tolerance (B-series), 60 Ω max differential resistance at IZ = 5 mA, and AEC-Q101 qualification for automotive environments. It delivers stable reverse breakdown under 5 mA test current and supports low-leakage operation with IR ≤ 2 μA at VR = 4.96 V.
For engineers reviewing the PDZ5.1BGW datasheet, PDZ5.1BGW pinout, PDZ5.1BGW application, or PDZ5.1BGW equivalent, key selection criteria include its tight 5.1 V Zener voltage tolerance, low thermal coefficient (+0.3 mV/K), 365 mW total power dissipation on standard FR4 PCB, and SOD123 surface-mount compatibility for space-constrained board designs.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable reference voltage across load variations. Its 5.1 V nominal Zener voltage is specified at IZ = 5 mA, with typical differential resistance of 60 Ω and temperature coefficient of +0.3 mV/K - indicating minimal drift over temperature in mid-range voltage references.
The device uses planar epitaxial construction for consistent parametric performance and reliability. It is rated for non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs), and junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCB - critical for transient surge handling and steady-state thermal design.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V1 | Same 5.1 V nominal, ±5 % tolerance (C-series), 500 mW Ptot, SOD323 package | Higher power but looser tolerance; smaller footprint increases thermal stress risk on FR4 | Select only if higher Ptot is needed and ±5 % regulation error is acceptable |
| MMSZ5231B | 5.1 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package, no AEC-Q101 qualification | Lacks automotive qualification; higher IR (5 μA) and rdif (17 Ω typ) but same footprint | Acceptable for industrial/commercial use where AEC-Q101 is not mandated |
Compared with BZX584-C5V1 and MMSZ5231B, PDZ5.1BGW offers tighter ±2 % tolerance and AEC-Q101 qualification - making it uniquely suitable for automotive and high-accuracy reference designs where long-term stability and qualification compliance are mandatory.

FAQ
What is the maximum continuous reverse current the PDZ5.1BGW can sustain at 25 °C?
The PDZ5.1BGW is rated for a maximum continuous forward current of 200 mA, but as a Zener diode operated in reverse breakdown, its safe continuous reverse current is determined by power dissipation limits. At 25 °C ambient on standard FR4 PCB, it supports up to ~71 mA (365 mW ÷ 5.1 V) without exceeding Ptot. Derating is required above 25 °C per the 340 K/W Rth(j-a).
How does the +0.3 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With a +0.3 mV/K coefficient, the Zener voltage shifts by approximately +49.5 mV across a 165 K range (−40 °C to +125 °C), resulting in a total variation of ±24.75 mV around 5.1 V - well within ±0.5 % of nominal. This low drift supports stable reference performance in automotive and industrial environments without active compensation.
Can PDZ5.1BGW replace PDZ5.1B in existing designs?
Yes - PDZ5.1BGW is the automotive-qualified (AEC-Q101) version of PDZ5.1B, sharing identical electrical specifications, SOD123 package, pinout, and marking (B9). The "GW" suffix denotes enhanced reliability testing and qualification; no layout or schematic changes are required for drop-in replacement in new or legacy designs targeting automotive use.
What is the recommended soldering profile for PDZ5.1BGW's SOD123 package?
Nexperia specifies reflow soldering only for PDZ5.1BGW. The recommended profile follows J-STD-020: peak temperature ≤ 260 °C, time above 217 °C ≤ 60 seconds, and ramp-up rate ≤ 3 °C/s. The SOD123 footprint requires 0.81 mm × 1.11 mm solder pads with 2.36 mm center-to-center spacing - matching standard IPC-7351B land patterns for mechanical reliability and thermal transfer.
