Product details
Overview
PDZ3.3BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection at 3.3 V nominal working voltage (IZ = 5 mA), ±2 % tolerance, 5 μA max reverse current at VR = 2.64 V, and AEC-Q101 qualification for automotive-grade reliability in compact surface-mount designs.
For engineers reviewing the PDZ3.3BGW datasheet, PDZ3.3BGW pinout, PDZ3.3BGW application, or PDZ3.3BGW equivalent, this device supports stable low-voltage reference generation, ESD clamp circuits, and power rail supervision where tight Zener voltage tolerance, low thermal drift, and surge robustness (40 W non-repetitive peak power) are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal Zener voltage of 3.32–3.53 V at 5 mA test current, exhibiting a temperature coefficient of −2.4 mV/K and differential resistance ≤95 Ω - enabling stable regulation across ambient temperatures from −55 °C to +150 °C.
Its SOD123 package delivers low thermal resistance (Rth(j-a) = 340 K/W in free air; Rth(j-sp) = 200 K/W on PCB), supports reflow soldering only, and features cathode identification via a marking bar - aligning with automotive PCB assembly requirements and high-reliability board-level protection schemes.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V3 | Same SOD323 package; ±2 % tolerance; 90 Ω rdif; 200 mW Ptot | Lower power rating limits surge handling (25 W PZSM) and thermal margin in high-ambient environments | Select when board space is constrained and peak surge energy is below 2.5 mJ |
| MMSZ4683T1G | SOD123 package; ±5 % tolerance; 100 Ω rdif; 500 mW Ptot; no AEC-Q101 | Looser tolerance increases reference uncertainty; lacks automotive qualification and tighter thermal specs | Select for cost-sensitive industrial applications where AEC-Q101 is not required and ±5 % regulation is acceptable |
Compared with BZX384-B3V3 and MMSZ4683T1G, PDZ3.3BGW uniquely combines AEC-Q101 qualification, ±2 % tolerance, and 40 W surge capability in SOD123 - making it optimal for automotive and high-reliability industrial systems requiring both precision and ruggedness.

FAQ
What is the maximum continuous reverse current the PDZ3.3BGW can sustain at 25 °C?
The PDZ3.3BGW has a total power dissipation limit of 365 mW at Tamb ≤ 25 °C. With a nominal Zener voltage of 3.32–3.53 V, this corresponds to a maximum continuous reverse current of approximately 104–110 mA - calculated as Ptot/VZ(min). Exceeding this current risks thermal runaway and permanent damage.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At a 3.3 V nominal Zener voltage, the −2.4 mV/K coefficient causes a −0.24 V shift over a 100 K rise (e.g., −40 °C to +60 °C). Combined with ±2 % initial tolerance, total regulation error remains within ±3.2 % across that range - sufficient for non-critical biasing but requires compensation in precision reference designs.
Can PDZ3.3BGW be used in parallel for higher power dissipation?
No - Zener diodes exhibit negative temperature coefficients and mismatched VZ values, causing current hogging when paralleled. Even matched units require ballast resistors, which defeat the purpose of low-drop regulation. For higher power, select a single higher-rated Zener or switch to an active regulator.
Is the SOD123 footprint compatible with automated optical inspection (AOI) systems?
Yes - the SOD123 package has standardized dimensions (3.75 × 2.55 mm) and visible cathode marking bar, enabling reliable AOI detection of placement orientation, solder joint quality, and polarity verification in high-volume automotive PCB assembly lines.
