Product details
Overview
PDZ22BGW from Nexperia is a single Zener diode in SOD123 package, rated for 22 V nominal Zener voltage at 5 mA, ±2 % tolerance (B-series), 100 Ω maximum differential resistance, and AEC-Q101 qualified for automotive use. It provides precision voltage regulation in low-power biasing, reference, and overvoltage protection circuits with 365 mW total power dissipation at 25 °C ambient.
For engineers reviewing the PDZ22BGW datasheet, PDZ22BGW pinout, PDZ22BGW application, or PDZ22BGW equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (200 K/W junction-to-solder-point), reverse current (≤0.05 μA at VR = 17 V), temperature coefficient (+17.0 to +18.4 mV/K), and SOD123 surface-mount compatibility with standard reflow profiles.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ = 21.54 V (min) to 22.47 V (max) at IZ = 5 mA, delivering stable reference voltage under varying load and temperature conditions. Its low differential resistance (≤100 Ω) ensures minimal dynamic impedance variation across operating current range.
AEC-Q101 qualification confirms robustness for automotive environments, supported by 150 °C maximum junction temperature, −55 °C to +150 °C ambient operating range, and non-repetitive peak reverse current capability of 1.3 A (tp = 100 μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 21.54 V to 22.47 V at IZ = 5 mA - defines precise regulation point for feedback or reference circuits |
| Tolerance | ±2 % (B-series) - enables high-accuracy voltage references without external trimming |
| Differential Resistance rdif | ≤100 Ω - ensures stable output under small-signal AC variations and load transients |
| Reverse Current IR | ≤0.05 μA at VR = 17 V - minimizes leakage-induced error in high-impedance bias networks |

| Total Power Dissipation Ptot | 365 mW at Tamb ≤ 25 °C - sets maximum continuous DC power handling on standard FR4 PCB |
| Thermal Resistance Rth(j-sp) | 200 K/W - determines junction temperature rise above solder point under steady-state bias |

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 | Same 22 V nominal, ±5 % tolerance, SOT23 package, 300 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive or industrial environments requiring extended temperature or reliability validation | Select when cost sensitivity outweighs automotive qualification and tighter tolerance requirements |
| MMSZ5248B | 22 V nominal, ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101, higher IR (≤1.0 μA at VR = 17 V) | Acceptable for general-purpose regulation where leakage and qualification are not critical; lacks automotive traceability | Choose for legacy designs already using MMSZ series, but verify thermal margin due to higher Ptot derating |
Compared with BZX84-C22 and MMSZ5248B, PDZ22BGW offers superior voltage accuracy (±2 % vs. ±5 %), guaranteed automotive qualification, and lower leakage-making it the preferred choice for safety-critical or thermally constrained applications demanding long-term stability.

FAQ
What is the maximum continuous forward current for PDZ22BGW?
The PDZ22BGW is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per the datasheet limiting values table. However, forward conduction is not its functional mode-forward voltage is specified only for characterization (0.9 V at 10 mA), and sustained forward bias is not recommended for regulation purposes.
How does the temperature coefficient affect regulation accuracy over −40 °C to +125 °C?
At IZ = 5 mA, PDZ22BGW exhibits a temperature coefficient of +17.0 to +18.4 mV/K. Over a 165 °C range, this translates to approximately ±1.5 V total drift-requiring system-level compensation in high-precision applications, especially where reference stability below ±1 % is required across full automotive temperature range.
Can PDZ22BGW replace PDZ22B in existing designs?
Yes-PDZ22BGW is the automotive-qualified, green (halogen-free) version of PDZ22B, sharing identical electrical specifications, SOD123 package, pinout, and marking (BQ). The "GW" suffix denotes AEC-Q101 qualification and RoHS-compliant material content, making it a direct upgrade for automotive and industrial designs requiring enhanced reliability and environmental compliance.
What PCB layout practices optimize thermal performance for PDZ22BGW?
To maintain junction temperature within 150 °C limit, use a 1 cm² copper pad connected to the cathode terminal (per datasheet condition [3]), apply standard SOD123 reflow footprint (4.18 mm × 1.11 mm solder mask opening), and avoid thermal isolation. Thermal resistance drops from 340 K/W (free air) to 200 K/W with proper pad design-enabling full 365 mW dissipation at 25 °C ambient.
