Product details
Overview
PDZ20BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at 20 V nominal Zener voltage (VZ = 19.52–20.39 V @ IZ = 5 mA), ±2 % tolerance (B-series), 100 Ω max differential resistance, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ20BGWJ datasheet, PDZ20BGWJ pinout, PDZ20BGWJ application, or PDZ20BGWJ equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (Rth(j-sp) = 50 K/W), non-repetitive surge capability (IZSM = 1.5 A), and surface-mount compatibility with standard FR4 PCB footprints.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable DC voltage under varying load or supply conditions. Its 20 V nominal working voltage targets mid-range regulation needs where higher-voltage references (e.g., >15 V) are required without excessive power dissipation.
It features low temperature coefficient (SZ = +15.0 to +16.4 mV/K @ IZ = 5 mA), low reverse current (IR ≤ 0.05 μA @ VR = 15.0 V), and fast transient response enabled by low junction capacitance (Cd = 88 pF @ f = 1 MHz, VR = 0 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 20 V - precise regulation point for 18–22 V system rails or feedback references |
| Tolerance | ±2 % (B-series) - tight voltage binning ensures predictable circuit behavior across production lots |
| IZ test current | 5 mA - standard operating point for specified VZ, rdif, and temperature coefficient |
| rdif max | 100 Ω - low dynamic impedance improves regulation stability under load variation |
| Ptot | 365 mW @ Tamb ≤ 25 °C - sufficient for low-power biasing and reference applications |
| IZSM | 1.5 A (tp = 100 μs) - handles short-duration transients without failure |
| Rth(j-sp) | 50 K/W - enables effective heat transfer from junction to solder point on standard FR4 PCB |
Pinout & Package
SOD123 plastic surface-mount package: 2.80 mm × 1.70 mm footprint, 1.3 mm height, cathode-marked with bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal |
| 2 | Anode (A) | Connected to ground or lower-potential rail; reverse-biased during regulation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress-test requirements (temperature cycling, HTRB, etc.) |
| Low differential resistance | 100 Ω max ensures minimal output voltage shift under ±1 mA load change |
| Stable temperature coefficient | +15.0 to +16.4 mV/K enables predictable VZ drift over −55 °C to +150 °C |
| Small SMD footprint | SOD123 package supports high-density PCB layouts and automated reflow assembly |
| Non-repetitive surge rating | 40 W peak power (100 μs pulse) protects against ESD and line transients |
Applications
| Automotive Body Control Module | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Voltage reference for microcontroller ADC input scaling in door module ECUs. IC Role / Device Role / Timing Role: Zener diode provides stable 20 V reference for resistive divider feeding 3.3 V ADC input.

Use Scenario: Precision biasing of bridge amplifier inputs in pressure sensor front-ends. IC Role / Device Role / Timing Role: Regulates excitation voltage for Wheatstone bridge, improving common-mode rejection. Use Value: Low IR (<0.05 μA) prevents loading error; AEC-Q101 rating supports extended field life. |
| Power Supply Overvoltage Clamp | USB-C Port Protection Circuit |
Use Scenario: Secondary-side clamp protecting 19 V DC-DC converter output from transient overshoot. IC Role / Device Role / Timing Role: Fast-acting shunt device clamps voltage above 20.4 V before downstream ICs are damaged.

Use Scenario: VBUS line protection in USB-C receptacle designs with 20 V PD support. IC Role / Device Role / Timing Role: Zener referenced to ground limits VBUS to safe level during fault conditions. Use Value: SOD123 size fits compact connector layout; 88 pF capacitance avoids signal integrity impact on CC lines. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C20 | Same 20 V nominal, ±5 % tolerance, SOT23 package, Ptot = 300 mW | Higher tolerance and smaller thermal mass limit use in precision or high-temp environments | Select when cost sensitivity outweighs voltage accuracy and thermal performance |
| MMSZ4684 | 20 V nominal, ±5 %, SOD123 package, Ptot = 500 mW, no AEC-Q101 qualification | Lacks automotive qualification; higher power rating suits non-automotive 20 V clamping | Prefer for industrial power supplies where AEC-Q101 is not mandated |
Compared with BZX84-C20 and MMSZ4684, PDZ20BGWJ delivers tighter voltage control, superior thermal performance (50 K/W vs ≥250 K/W), and automotive qualification-making it optimal for safety-critical or thermally constrained 20 V reference designs.

FAQ
What is the maximum continuous reverse current (IR) for PDZ20BGWJ at 15 V?
At VR = 15.0 V and Tj = 25 °C, the reverse current is ≤0.05 μA. This ultra-low leakage ensures minimal power loss and negligible loading on high-impedance reference nodes, critical for battery-powered or precision analog circuits.
Can PDZ20BGWJ be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For higher power, use a single higher-rated device or active regulation instead.
Is the SOD123 footprint compatible with standard reflow profiles?
Yes-Nexperia specifies reflow soldering only, with validated thermal profile compliance for lead-free processes (peak 260 °C). The recommended footprint (4.18 mm × 1.42 mm pad spacing) matches IPC-7351B SOD123 standards.
Does PDZ20BGWJ support bidirectional transient suppression?
No-it is a unidirectional Zener diode optimized for reverse-bias regulation. For bidirectional ESD protection, pair it with a series forward diode or select a dedicated TVS array; its 1.5 A IZSM applies only to reverse polarity pulses.
