Product details
Overview
PDZ22BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions in low-power analog circuits. It delivers a nominal Zener voltage of 22 V at 5 mA, ±2 % tolerance (B-series), 100 Ω typical differential resistance, 25 μA max reverse current at 17.6 V, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ22BGWX datasheet, PDZ22BGWX pinout, PDZ22BGWX application, or PDZ22BGWX equivalent, this device is selected for stable 22 V clamping in power supply feedback loops, overvoltage protection on sensor interfaces, and precision biasing in automotive control modules where thermal stability and tight voltage tolerance are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 21.54 V (min) to 22.47 V (max) at IZ = 5 mA, exhibiting a temperature coefficient of +17.0 mV/K (typ) and +18.4 mV/K (max), enabling predictable drift compensation in temperature-sensitive references. Its low 100 Ω differential resistance ensures minimal voltage variation under load changes.
The device supports non-repetitive peak reverse current up to 1.3 A (tp = 100 μs) and total power dissipation of 365 mW at Tamb ≤ 25 °C on standard FR4 PCB - validated for reflow soldering per JEDEC J-STD-020 and qualified to AEC-Q101 for automotive underhood environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C22 | ±5 % tolerance, 400 mW Ptot, SOT23 package, no AEC-Q101 qualification | Higher voltage drift and unqualified for automotive; suitable only for commercial-grade consumer power supplies | Select when cost sensitivity outweighs precision and automotive compliance requirements |
| MMSZ5247B | ±5 % tolerance, 500 mW Ptot, SOD123 package, no AEC-Q101 qualification | Larger voltage spread increases calibration burden; lacks automotive stress-test validation | Prefer only if higher power margin is required and automotive qualification is not mandated |
Compared with BZX84-C22 and MMSZ5247B, PDZ22BGWX provides tighter ±2 % tolerance, verified AEC-Q101 reliability, and lower differential resistance - making it the sole choice for automotive and industrial applications demanding long-term voltage stability and environmental robustness.

FAQ
What is the maximum steady-state power dissipation for PDZ22BGWX at 85 °C ambient?
At 85 °C ambient, derated power dissipation is 220 mW, calculated using the 365 mW rating at 25 °C and thermal resistance of 340 K/W. This allows continuous 22 V operation up to 10 mA while maintaining Tj ≤ 150 °C, confirmed per Nexperia's thermal derating curve in Section 6 of the datasheet.
How does the +17.0 mV/K temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
The +17.0 mV/K coefficient causes approximately +2.9 V total drift across the full range, resulting in a 22 V reference shifting from ~20.6 V to ~23.5 V. This is fully characterized in Figure 3 and must be compensated in high-accuracy designs via external circuitry or selection of complementary tempco components.
Is PDZ22BGWX compatible with lead-free reflow profiles per JEDEC J-STD-020?
Yes - PDZ22BGWX is qualified for lead-free reflow with peak temperature up to 260 °C (10 s max), matching standard JEDEC Level 1 moisture sensitivity and SOD123 footprint dimensions shown in Figure 9. The recommended profile uses ramp-to-spike with 60–120 s above 217 °C.
Can PDZ22BGWX replace PDZ22B in existing designs?
Yes - PDZ22BGWX is a direct replacement for PDZ22B, sharing identical electrical specifications, SOD123 package, pinout, and AEC-Q101 qualification. The 'X' suffix denotes tape-and-reel packaging per ordering code PDZ22BGWX, with no functional or performance differences.
