Product details
Overview
PDZ13BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at nominal 13 V (IZ = 5 mA), with ±2 % tolerance (B-series), 10.0 Ω typical differential resistance, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ13BGWX datasheet, PDZ13BGWX pinout, PDZ13BGWX application, or PDZ13BGWX equivalent, this device supports stable low-power voltage clamping, ESD-robust biasing, and temperature-compensated reference generation in space-constrained PCB layouts requiring high-reliability discrete regulation.
Technical Context
This Zener operates in reverse breakdown mode with a nominal working voltage of 13 V at 5 mA test current, exhibiting a temperature coefficient of +9.4 mV/K and reverse current ≤0.1 μA at VR = 10.0 V. Its thermal resistance from junction to solder point is 50 K/W under defined PCB mounting conditions.
The device delivers non-repetitive peak reverse power dissipation up to 40 W (tp = 100 μs) and total DC power dissipation of 365 mW at Tamb ≤ 25 °C, with forward voltage ≤0.9 V at IF = 10 mA - enabling bidirectional transient suppression and low-loss forward conduction when needed.

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, SOT23 package, Ptot = 300 mW | Higher tolerance and lower power rating reduce accuracy and surge margin in automotive use | Select when cost sensitivity outweighs AEC-Q101 requirement and thermal headroom is ample |
| MMSZ5242B | 13 V nominal, ±5 %, SOD123, Ptot = 350 mW, no AEC-Q101 qualification | Lacks automotive qualification and has higher rdif (20 Ω typ), limiting regulation stability | Acceptable for commercial-grade consumer power rails where qualification and precision are secondary |
Compared with BZX84-C13 and MMSZ5242B, PDZ13BGWX provides tighter ±2 % tolerance, AEC-Q101 validation, and superior thermal performance (Rth(j-sp) = 50 K/W), making it the preferred choice for automotive and industrial applications demanding long-term voltage stability and reliability.

FAQ
What is the maximum continuous reverse current the PDZ13BGWX can sustain at 13 V?
The PDZ13BGWX is rated for a maximum total power dissipation of 365 mW at Tamb ≤ 25 °C. At its nominal 13 V Zener voltage, this corresponds to a continuous reverse current limit of approximately 28 mA (365 mW ÷ 13 V). Derating is required above 25 °C ambient per the thermal resistance specification.
How does the +9.4 mV/K temperature coefficient affect circuit performance over temperature?
The +9.4 mV/K coefficient means the Zener voltage increases by ~9.4 mV per Kelvin rise in junction temperature. Over a −40 °C to +125 °C ambient range (ΔT ≈ 165 K), this contributes ~1.55 V drift - but combined with ±2 % initial tolerance, the full variation remains within ±3.5 % of nominal, verified in automotive-grade qualification testing.
Can PDZ13BGWX be used in parallel for higher power handling?
No - Zener diodes exhibit negative dynamic resistance and mismatched characteristics; paralleling them causes current hogging and thermal runaway. For higher power, use a single higher-rated device or implement active regulation. The PDZ-GW series is not characterized or qualified for parallel operation.
Is the SOD123 footprint compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method, with footprint dimensions (4.18 mm × 1.42 mm pad area) and thermal profile guidance published in Figure 9 of the datasheet. The package withstands JEDEC J-STD-020-compliant peak temperatures up to 260 °C.
