Product details
Overview
PDZ11BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage of 11.0 V at 5 mA, ±2 % tolerance (B-series), 8.0 Ω typical differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ11BGWJ datasheet, PDZ11BGWJ pinout, PDZ11BGWJ application, or PDZ11BGWJ equivalent, this device is selected for low-noise voltage clamping, overvoltage protection in power rails, and stable biasing in analog sensor interfaces where tight voltage tolerance and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 10.78 V to 11.22 V at IZ = 5 mA, exhibiting a temperature coefficient of +7.4 mV/K - indicating positive drift with junction temperature rise. Its low reverse current (≤0.1 μA at VR = 9.1 V) supports high-impedance sensing nodes.
The device delivers non-repetitive peak reverse current up to 3.0 A (tp = 100 μs) and maintains thermal resistance from junction to solder point at 50 K/W when mounted on a 1 cm² cathode pad - enabling robust transient suppression in compact PCB layouts.
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-C11 | Same 11 V nominal, ±5 % tolerance, SOT23 package, higher rdif (20 Ω) | Larger footprint, lower surge rating (PZSM = 25 W), no AEC-Q101 qualification | Select for cost-sensitive consumer designs where automotive reliability and tight tolerance are not required |
| MMSZ5240B | 11 V nominal, ±5 %, SOD123 package, 15 Ω rdif, Ptot = 350 mW | Lower surge capability (IZSM = 2.2 A), no AEC-Q101, wider VZ spread | Choose when legacy design compatibility with ON Semiconductor footprint is mandatory |
Compared with BZX84-C11 and MMSZ5240B, PDZ11BGWJ offers tighter ±2 % tolerance, lower 8.0 Ω differential resistance, and AEC-Q101 qualification - making it uniquely suitable for automotive and high-accuracy industrial references where regulation stability and transient immunity are critical.

FAQ
What is the maximum continuous power dissipation for PDZ11BGWJ at 25 °C ambient?
The total power dissipation (Ptot) is rated at 365 mW under standard FR4 PCB mounting conditions (single-sided copper, tin-plated, standard footprint). With an enlarged 1 cm² cathode pad, this increases to 625 mW - enabling sustained operation at 56 mA Zener current without exceeding thermal limits.
How does the +7.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At 11 V nominal, +7.4 mV/K corresponds to +0.067 %/°C drift. Over a −40 °C to +125 °C range (165 K ΔT), total drift is +1.22 V - resulting in VZ = 10.78 V to 12.00 V. This is fully characterized in the datasheet and usable in compensated designs where absolute accuracy is secondary to monotonic behavior.
Can PDZ11BGWJ be used in parallel for higher current handling?
No - Zener diodes exhibit negative temperature coefficients below ~5 V and positive above, but even within the same batch, minor VZ mismatches cause current hogging. The PDZ-GW series is not characterized or recommended for parallel operation; use a single higher-power device or active regulation instead.
Is the SOD123 package compatible with standard reflow profiles for lead-free assembly?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD123 footprint supports JEDEC J-STD-020-compliant lead-free profiles (peak 260 °C, 20–40 s above 217 °C), with thermal pad design guidelines provided in Figure 9 of the datasheet for optimal solder joint reliability.
