Product details
Overview
PDZ6.2BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at nominal 6.2 V with ±2 % tolerance (B-series), 50 Ω typical differential resistance at IZ = 5 mA, 0.5 μA max reverse current at VR = 4.96 V, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ6.2BGW datasheet, PDZ6.2BGW pinout, PDZ6.2BGW application, or PDZ6.2BGW equivalent, this device supports low-power voltage clamping, overvoltage protection, and stable biasing in space-constrained PCB layouts where thermal performance and automotive-grade reliability are required.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 6.2 V at IZ = 5 mA, exhibiting a temperature coefficient of +2.7 mV/K - indicating positive drift with junction temperature rise. Its differential resistance remains ≤50 Ω under rated test conditions, enabling tight regulation in feedback loops.
The device delivers 365 mW total power dissipation on standard FR4 PCB (single-sided copper, tin-plated) and withstands non-repetitive peak reverse power up to 40 W for 100 μs pulses. Thermal resistance from junction to solder point is 50 K/W, supporting reliable operation in thermally demanding placements near heat sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V2 | Same 6.2 V nominal, ±5 % tolerance (C-series), SOT23 package, 300 mW Ptot | Higher voltage tolerance and smaller package reduce board area but increase regulation uncertainty | Select when cost sensitivity outweighs precision; not recommended for automotive AEC-Q101 requirements |
| MMSZ4687 | 6.2 V nominal, ±5 %, SOD123 package, 500 mW Ptot, no AEC-Q101 qualification | Higher power rating allows higher continuous current but lacks automotive stress validation | Prefer for industrial non-automotive designs needing extra margin; verify thermal design for 500 mW derating |
Compared with BZX84-C6V2 and MMSZ4687, PDZ6.2BGW offers tighter ±2 % tolerance, AEC-Q101 qualification, and optimized thermal resistance for automotive PCB layouts - making it the only choice where regulation accuracy and automotive reliability are jointly mandated.

FAQ
What is the maximum continuous reverse current the PDZ6.2BGW can sustain at 25 °C ambient?
The PDZ6.2BGW sustains up to 57 mA continuous reverse current at 25 °C ambient, calculated from its 365 mW total power dissipation limit and nominal 6.2 V Zener voltage (Ptot/VZ). This assumes standard FR4 PCB mounting with single-sided copper and tin plating per datasheet condition [2]. Derating applies above 25 °C ambient.
How does the +2.7 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
With +2.7 mV/K tempco, VZ shifts +420 mV across 155 K temperature span (−40 °C to +125 °C), resulting in ~+6.8 % deviation from nominal 6.2 V. This is fully characterized in Figures 3–4 of the datasheet and must be compensated in high-accuracy references using external circuitry or calibration.
Can PDZ6.2BGW replace PDZ6.2B in existing designs?
Yes - PDZ6.2BGW is a direct replacement for PDZ6.2B, sharing identical electrical specifications, SOD123 package, pinout, and AEC-Q101 qualification. The "GW" suffix denotes updated wafer fabrication and enhanced process control, with no functional or mechanical differences affecting board-level compatibility.
What is the minimum recommended PCB copper area for cathode pad to achieve 50 K/W thermal resistance?
A 1 cm² copper pad connected to the cathode terminal is required to achieve the specified 50 K/W Rth(j-sp), as defined in Table 6 footnote [3]. This pad must be single-sided, tin-plated, and directly attached to the cathode metallization - split planes or thermal vias are not accounted for in the rated value.
