Product details
Overview
PDZ13BGWJ from Nexperia is a single Zener diode in SOD123 package, rated for 13 V nominal Zener voltage at 5 mA test current, ±2 % tolerance (B-series), 365 mW total power dissipation at 25 °C ambient, and AEC-Q101 qualified for automotive use. It provides precise voltage regulation in compact surface-mounted designs with low reverse leakage (≤0.1 μA at VR = 10 V) and differential resistance of 80 Ω max.
For engineers reviewing the PDZ13BGWJ datasheet, PDZ13BGWJ pinout, PDZ13BGWJ application, or PDZ13BGWJ equivalent, this device is selected for stable reference generation, overvoltage clamping, and ESD-robust biasing in automotive body control modules, industrial sensor signal conditioning, and DC-DC feedback networks where tight voltage tolerance and thermal reliability are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage across its cathode-anode terminals. Its 13 V nominal Zener voltage is specified at IZ = 5 mA with temperature coefficient of +9.4 mV/K, enabling predictable drift compensation in temperature-sensitive circuits.
The SOD123 package delivers low thermal resistance (Rth(j-a) = 340 K/W in free air; Rth(j-sp) = 200 K/W on PCB), supporting reliable power handling up to 40 W non-repetitive peak surge (tp = 100 μs) while maintaining junction temperature ≤150 °C under defined mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 12.91 V to 13.49 V at IZ = 5 mA - ensures ±2 % regulation accuracy for precision reference applications |
| Differential Resistance (rdif) | ≤80 Ω - minimizes output impedance variation under load changes in feedback loops |
| Reverse Current (IR) | ≤0.1 μA at VR = 10 V - enables ultra-low standby power in battery-backed circuits |
| Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C - defines continuous thermal limit on standard FR4 PCB with tin-plated copper |
| Non-repetitive Peak Power (PZSM) | 40 W for tp ≤ 100 μs - supports transient overvoltage suppression without failure |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - allows low-loss forward conduction during polarity-reversal protection |
| Thermal Resistance (Rth(j-sp)) | 200 K/W - quantifies junction-to-solder-point heat transfer efficiency on optimized PCB pad |
Pinout & Package
SOD123 plastic surface-mount package: 2.80 mm × 1.70 mm footprint, 1.3 mm height, cathode marked by bar on top surface.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal, ±5 % tolerance, 300 mW Ptot, SOT23 package | Higher tolerance and lower power rating reduce accuracy and surge margin in automotive environments | Select when cost is primary constraint and AEC-Q101 qualification is not required |
| MMSZ4686 | 13 V nominal, ±5 %, 500 mW Ptot, SOD123 package, no AEC-Q101 qualification | Larger power margin but unqualified for automotive use; lacks documented surge performance data | Select for industrial non-automotive applications needing higher continuous power |
Compared with BZX84-C13 and MMSZ4686, PDZ13BGWJ offers tighter ±2 % tolerance, AEC-Q101 validation, and verified 40 W surge capability-making it the only choice for automotive-critical voltage references requiring both precision and robustness.

FAQ
What is the maximum reverse voltage (VR) that PDZ13BGWJ can withstand before breakdown?
The PDZ13BGWJ exhibits a sharp Zener breakdown at its nominal 13 V working voltage when reverse-biased. Its maximum non-breakdown reverse voltage is defined by the test condition VR = 10 V in the IR specification - meaning it maintains ≤0.1 μA leakage up to 10 V, and enters controlled breakdown above ~12.9 V. It is not rated for sustained operation below breakdown voltage.
How does the +9.4 mV/K temperature coefficient affect circuit performance?
The +9.4 mV/K coefficient means the Zener voltage increases by approximately 9.4 mV per degree Celsius rise in junction temperature. At 13 V nominal, this yields ~0.072 %/°C drift - predictable and linear, allowing accurate compensation in temperature-stable references when combined with negative-TC components or digital correction.
Can PDZ13BGWJ be used in parallel for higher power handling?
No - Zener diodes exhibit manufacturing variations in VZ and rdif, causing current imbalance when paralleled. Even with matched units, thermal runaway risk remains due to positive temperature coefficient. For higher power, use a single higher-rated Zener or switch to active regulation with a transistor-assisted shunt.
Is the SOD123 package compatible with standard reflow profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD123 footprint complies with IPC-7351B, and the device supports JEDEC J-STD-020D peak temperatures up to 260 °C for ≤30 seconds, with preheat ramp rates ≤3 °C/s and cooling rate ≥1 °C/s.
