Product details
Overview
PDZ10BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at nominal 10 V (IZ = 5 mA), with ±2 % tolerance (B-series), 7.0 Ω typical differential resistance, and 0.1 μA max reverse current at VR = 9.1 V. It supports automotive-grade reliability per AEC-Q101 and operates across −55 °C to +150 °C ambient.
For engineers reviewing the PDZ10BGWX datasheet, PDZ10BGWX pinout, PDZ10BGWX application, or PDZ10BGWX equivalent, this device is selected for low-drift, surface-mount voltage clamping in power supply feedback loops, overvoltage protection circuits, and analog reference design where tight Zener voltage tolerance and thermal stability are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a nominal working voltage of 10 V at 5 mA test current, exhibiting a temperature coefficient of +6.4 mV/K - indicating positive drift with junction temperature rise. Its differential resistance of ≤7.0 Ω ensures stable regulation under varying load currents.
The device features AEC-Q101 qualification, confirming suitability for automotive environments, and uses a planar epitaxial construction for consistent breakdown characteristics. Thermal resistance from junction to solder point is 50 K/W, enabling effective heat dissipation when mounted on a 1 cm² cathode pad per JEDEC standards.

FAQ
What is the maximum steady-state power dissipation for PDZ10BGWX on a standard FR4 PCB?
PDZ10BGWX has a total power dissipation (Ptot) of 365 mW at Tamb ≤ 25 °C when mounted on an FR4 PCB with single-sided copper and standard SOD123 footprint. Derating is required above 25 °C at 3.4 mW/°C based on thermal resistance of 200 K/W to ambient.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
PDZ10BGWX exhibits a +6.4 mV/K temperature coefficient at IZ = 5 mA, resulting in ~1.28 V drift from −40 °C to +125 °C. This is mitigated in practice by operating at higher test currents (e.g., 10 mA) where coefficient improves to +5.5 mV/K, reducing total drift to ~1.1 V.
Is PDZ10BGWX suitable for use in reverse-biased ESD protection on high-speed data lines?
No - PDZ10BGWX is not optimized for high-speed ESD clamping due to its relatively high junction capacitance (~110 pF at 0 V) and slower response compared to dedicated TVS diodes. It is intended for DC regulation and low-frequency overvoltage protection, not signal-line transient suppression.
What does the 'BG' marking code indicate for PDZ10BGWX?
The 'BG' marking code corresponds to the PDZ10BGW type number per Nexperia's marking table (Table 4), confirming nominal 10 V Zener voltage and ±2 % tolerance (B-series). The 'G' denotes the SOD123 package variant, distinguishing it from legacy SOD323 or DO-35 versions.
