Product details
Overview
PDZ11BGWX from Nexperia is a single Zener diode in SOD123 surface-mount package, designed for precision voltage regulation and reference applications at nominal 11 V (IZ = 5 mA), with ±2 % tolerance (B-series), 8.0 V maximum reverse voltage (VR), and 300 mW total power dissipation at Tamb ≤ 25 °C. It delivers stable clamping in low-power analog circuits, ESD-protected I/O rails, and automotive-grade sensor biasing.
For engineers reviewing the PDZ11BGWX datasheet, PDZ11BGWX pinout, PDZ11BGWX application, or PDZ11BGWX equivalent, key selection criteria include its AEC-Q101 qualification, 10.78–11.22 V working voltage range, 8.0 Ω typical differential resistance, −7.4 mV/K temperature coefficient, and thermal resistance of 200 K/W to solder point - all critical for automotive and industrial voltage-reference stability.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ at IZ = 5 mA, exhibiting low dynamic impedance (rdif ≤ 60 Ω) and minimal temperature drift (SZ = −7.4 mV/K). Its SOD123 footprint enables high-density PCB layouts while maintaining thermal performance via optimized cathode pad design.
The device supports non-repetitive surge handling up to 3.0 A peak reverse current (IZSM) for transient suppression, and maintains < 0.1 μA reverse leakage at VR = 8.0 V. Its forward voltage is 0.9 V at IF = 10 mA, enabling dual-use as a low-drop rectifier in auxiliary paths.

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, 300 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive environments | Select only for cost-sensitive, non-automotive applications where ±5 % tolerance is acceptable |
| MMSZ5240B | 10 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101 qualification | Lower voltage and wider tolerance reduce accuracy in precision reference roles | Use only if 10 V regulation suffices and automotive qualification is not required |
Compared with BZX84-C11 and MMSZ5240B, PDZ11BGWX provides tighter ±2 % tolerance, −7.4 mV/K tempco, and AEC-Q101 qualification - making it uniquely suitable for automotive sensor biasing and industrial analog references where long-term stability and environmental ruggedness are mandatory.

FAQ
What is the maximum continuous power dissipation for PDZ11BGWX at 25 °C ambient?
PDZ11BGWX has a total power dissipation (Ptot) of 365 mW at Tamb ≤ 25 °C when mounted on an FR4 PCB with standard footprint. With enhanced cathode pad (1 cm²), it supports up to 625 mW - confirmed in Table 5 and Table 6 of the official Nexperia datasheet Rev. 1 (2017).
Is PDZ11BGWX suitable for automotive applications?
Yes - PDZ11BGWX is explicitly AEC-Q101 qualified per Section 8.1 of the Nexperia datasheet, making it approved for use in automotive powertrain, chassis, and body electronics where reliability under thermal cycling and vibration is critical.
What is the reverse leakage current at 8.0 V?
At VR = 8.0 V and Tj = 25 °C, the reverse current (IR) is ≤ 0.1 μA, as specified in Table 8 of the datasheet for the PDZ11BGW variant. This ultra-low leakage supports micropower design in battery-operated systems.
How is the cathode identified on the PDZ11BGWX package?
The cathode (pin 1) is marked by a visible bar on the top surface of the SOD123 package, consistent with Figure 8 and Table 2 of the Nexperia datasheet. The anode (pin 2) is unmarked and occupies the opposite end of the body.
