Product details
Overview
PDZ16BGWX from Nexperia is a single Zener diode in SOD123 surface-mount package, designed for precision voltage regulation and reference applications at nominal 16 V (IZ = 5 mA), with ±2 % tolerance (B-series), 80 Ω max differential resistance, and AEC-Q101 qualification for automotive environments.
For engineers reviewing the PDZ16BGWX datasheet, PDZ16BGWX pinout, PDZ16BGWX application, or PDZ16BGWX equivalent, this device supports stable low-power voltage clamping in ECU power rails, sensor biasing circuits, and overvoltage protection stages where tight Zener voltage accuracy and thermal reliability under ambient extremes (−55 °C to +150 °C) are required.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 15.85 V to 16.51 V at 5 mA test current, exhibiting a temperature coefficient of +12.0 mV/K (typical) and reverse current ≤ 0.05 μA at VR = 12.0 V. Its non-repetitive peak reverse power dissipation is rated at 40 W for 100 μs pulses.
Thermal performance is defined by Rth(j-a) = 340 K/W (free air) and Rth(j-sp) = 200 K/W (on FR4 PCB with 1 cm² cathode pad), enabling reliable operation up to 150 °C junction temperature. The device uses planar epitaxial construction and is qualified per AEC-Q101 stress test requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 16 V at IZ = 5 mA; actual range 15.85–16.51 V ensures tight regulation in feedback loops |
| Tolerance | ±2 % (B2 series); enables accurate voltage reference without post-production trimming |
| Differential Resistance | ≤ 80 Ω; maintains low dynamic impedance for stable regulation under load variation |
| Reverse Current | ≤ 0.05 μA at VR = 12.0 V; minimizes standby power loss in battery-powered systems |
| Power Dissipation | 365 mW at Tamb ≤ 25 °C; sufficient for low-current bias and clamp functions on standard PCBs |
| Temperature Coefficient | +12.4 mV/K (typical at IZ = 5 mA); positive drift allows predictable compensation in temp-stable references |

Pinout & Package
The PDZ16BGWX is housed in a SOD123 plastic surface-mount package (3.75 × 2.55 × 1.3 mm), featuring a cathode-marked end (bar marking) and optimized thermal pad layout for solder-point heat transfer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 (A) | Anode | Connected to ground or lower-potential rail; reverse-biased configuration enables Zener operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | Same 16 V nominal, but ±5 % tolerance (C-grade), 150 Ω rdif, no AEC-Q101 qualification | Suitable for consumer-grade power supplies; not recommended for automotive or industrial temperature-critical use | Select when cost sensitivity outweighs precision and qualification requirements |
| MMSZ4687 | 16 V nominal, ±5 %, 150 Ω rdif, 300 mW Ptot, AEC-Q101 qualified but higher IR (≤ 0.1 μA at 12 V) | Acceptable for automotive body modules; less optimal for ultra-low-leakage sensor biasing | Choose if existing BOM uses MMSZ footprint and qualification is mandatory but tighter tolerance is secondary |
Compared with BZX84-C16 and MMSZ4687, PDZ16BGWX delivers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (80 Ω vs. ≥150 Ω), and guaranteed low leakage-making it the preferred choice for high-stability reference and automotive-clamp applications where regulation fidelity directly impacts system safety or measurement integrity.

FAQ
What is the maximum continuous reverse current the PDZ16BGWX can sustain at 25 °C?
The PDZ16BGWX has a total power dissipation limit of 365 mW at Tamb ≤ 25 °C. At its nominal 16 V Zener voltage, this corresponds to a maximum continuous reverse current of approximately 22.8 mA (365 mW ÷ 16 V), assuming no additional thermal derating from PCB layout.
How does the +12.4 mV/K temperature coefficient affect regulation stability over temperature?
The positive temperature coefficient means the Zener voltage increases by ~12.4 mV per Kelvin rise in junction temperature. For a 100 °C rise (25 °C to 125 °C), voltage shifts ~1.24 V - predictable and compensatable in reference designs using matched TC components or software calibration.
Is the SOD123 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies reflow soldering as the only recommended method. The SOD123 footprint (4.18 mm × 1.42 mm pad spacing) supports IPC-7095-compliant profiles, with peak temperatures up to 260 °C and time above liquidus ≤ 60 seconds, verified per J-STD-020.
Can PDZ16BGWX replace PDZ15BGWX or PDZ18BGWX in an existing design?
No direct substitution is advised without circuit validation: PDZ15BGWX (14.34–14.98 V) and PDZ18BGWX (17.56–18.35 V) have non-overlapping Zener ranges. A 16 V target requires PDZ16BGWX's specific 15.85–16.51 V band to meet ±2 % tolerance; adjacent parts deviate >5 % from nominal.
