Product details
Overview
PDZ10BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and overvoltage protection in low-power circuits. It features a nominal Zener voltage of 10 V (9.77–10.21 V at IZ = 5 mA), ±2 % tolerance (B-series), 365 mW total power dissipation at Tamb ≤ 25 °C, and AEC-Q101 qualification for automotive-grade reliability. It operates with low reverse current (≤0.1 μA at VR = 8 V) and exhibits a temperature coefficient of +6.4 mV/K.
For engineers reviewing the PDZ10BGWJ datasheet, PDZ10BGWJ pinout, PDZ10BGWJ application, or PDZ10BGWJ equivalent, this device is selected for stable reference generation in sensor signal conditioning, ECU power-rail clamping, and low-current bias networks where tight voltage tolerance, thermal stability, and automotive-compliant ruggedness are required.
Technical Context
This Zener diode functions as a two-terminal shunt regulator, maintaining a stable reverse breakdown voltage across its cathode-anode terminals under controlled current conditions. Its differential resistance is ≤7 Ω at IZ = 5 mA, enabling low-voltage drift under load variation, and its junction-to-solder-point thermal resistance is 50 K/W - critical for thermal management on compact PCBs.
The device supports non-repetitive surge handling up to 40 W (tp = 100 μs), with peak reverse current rated at 3.5 A, and is characterized for operation from −55 °C to +150 °C ambient. Its capacitance is 110 pF at 1 MHz and 0 V, making it suitable for DC and low-frequency regulation-not RF bypass.
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-C10 | Same SOD-123 package, ±5 % tolerance, 300 mW Ptot, higher IR (≤5 μA at 8 V) | Lower accuracy and thermal stability; suited for non-critical supply rails | Select when cost priority outweighs voltage precision and automotive qualification |
| MMSZ5240B | SOD-123, ±5 %, 500 mW Ptot, no AEC-Q101, higher rdif (≤20 Ω) | Higher power but looser regulation; lacks automotive stress validation | Prefer for industrial power supplies where ambient temperature stays <85 °C |

FAQ
What is the maximum continuous forward current for PDZ10BGWJ?
The absolute maximum forward current is 200 mA per the datasheet limiting values table. However, sustained forward conduction is not part of its intended operation - it is designed for reverse-bias Zener regulation only. Forward voltage is specified at 10 mA (0.9 V max) and 100 mA (1.1 V max), confirming low-conduction-state behavior below 200 mA.
Is PDZ10BGWJ suitable for use in a 12 V automotive battery monitoring circuit?
Yes - its 10 V Zener voltage provides appropriate headroom below nominal 12 V and typical cranking peaks (~14.5 V). With 3.5 A non-repetitive surge rating and AEC-Q101 qualification, it reliably clamps transients such as load dump (ISO 7637-2 Pulse 5a) when paired with appropriate series impedance, and maintains regulation stability across −40 °C to +125 °C.
How does the ±2 % tolerance affect circuit accuracy in a feedback divider?
When used in a resistive divider for switching regulator feedback, the ±2 % VZ directly contributes to output voltage error. For a 10 V reference setting a 24 V output, this introduces ±0.48 V (±2 %) uncertainty before resistor tolerance and op-amp offset are considered - making it suitable for applications requiring ≤±3 % overall output tolerance without trimming.
Can PDZ10BGWJ replace a 1N4740A in an existing design?
No - the 1N4740A is DO-41 packaged (through-hole, 1 W Ptot) with ±5 % tolerance and different thermal characteristics. PDZ10BGWJ is SOD123 (SMT), 365 mW, ±2 %, and AEC-Q101 qualified. Direct replacement requires PCB footprint redesign, power derating analysis, and validation of surge performance in the new layout's thermal environment.
