Product details
Overview
PDZ3.6BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at 3.6 V nominal Zener voltage (IZ = 5 mA), ±2 % tolerance (B-series), 90 Ω max differential resistance, and AEC-Q101 qualified for automotive environments. It delivers stable clamping in low-power bias networks, ESD protection interfaces, and analog reference circuits.
For engineers reviewing the PDZ3.6BGWX datasheet, PDZ3.6BGWX pinout, PDZ3.6BGWX application, or PDZ3.6BGWX equivalent, key selection criteria include its 3.60–3.85 V working voltage range, 5 μA reverse current at VR = 1 V, −2.4 mV/K temperature coefficient, and SOD123 thermal performance with Rth(j-a) = 340 K/W in free air.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ stability across temperature and current. Its −2.4 mV/K temperature coefficient at IZ = 5 mA enables predictable drift compensation in reference designs, while low 5 μA IR at 1 V reverse bias supports high-impedance sensing nodes.
The device uses planar epitaxial construction for repeatable breakdown characteristics and integrates AEC-Q101 stress qualification-including HTGB, HTRB, and temperature cycling-ensuring reliability in automotive under-hood and infotainment power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 3.60–3.85 V at IZ = 5 mA - defines precise clamping threshold for 3.3 V system rail stabilization |
| Tolerance | ±2 % (B2 series) - ensures tight binning for reference-grade accuracy without external trimming |
| Differential Resistance (rdif) | ≤90 Ω - maintains low dynamic impedance for stable regulation under varying load currents |
| Reverse Current (IR) | 5 μA max at VR = 1 V - minimizes leakage in high-impedance bias networks and sensor references |
| Temperature Coefficient (SZ) | −2.4 mV/K at IZ = 5 mA - enables predictable thermal drift modeling in automotive ambient ranges (−40 to +125 °C) |
| Total Power Dissipation (Ptot) | 365 mW at Tamb ≤ 25 °C - supports continuous operation on standard FR4 PCB with single-sided copper |
| Non-repetitive Peak Power (PZSM) | 40 W (tp ≤ 100 μs) - provides transient overvoltage immunity against ESD and load dump events |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B3V6 | VZ = 3.6 V ±5 %, Ptot = 300 mW, no AEC-Q101 qualification | Not suitable for automotive; acceptable for consumer-grade power supply feedback | Select when cost sensitivity outweighs automotive compliance and tighter tolerance |
| MMSZ4685 | VZ = 3.6 V ±5 %, Ptot = 500 mW, SOD-123, AEC-Q101 qualified | Higher power rating but looser tolerance; higher IR (10 μA @ 1 V) | Prefer where thermal margin is critical but reference accuracy is secondary |
Compared with BZX384-B3V6 and MMSZ4685, PDZ3.6BGWX uniquely combines AEC-Q101 qualification, ±2 % tolerance, and low 5 μA IR-making it optimal for automotive sensor references and precision clamping where both reliability and accuracy are mandatory.

FAQ
What is the maximum steady-state power dissipation for PDZ3.6BGWX on a standard FR4 PCB?
The total power dissipation (Ptot) is 365 mW at Tamb ≤ 25 °C when mounted on an FR4 PCB with single-sided copper and standard footprint. Derating begins above 25 °C at 3.0 mW/°C, reaching 0 mW at 150 °C junction temperature. This rating assumes no extended cathode pad; using a 1 cm² cathode pad raises Ptot to 625 mW.
How does the −2.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, the −2.4 mV/K coefficient means VZ decreases by 2.4 mV per Kelvin rise. Over −40 °C to +125 °C (165 K span), total drift is approximately −396 mV from nominal 3.6 V-yielding a worst-case VZ range of ~3.20–3.85 V. This is fully characterized in Figure 3 of the datasheet and remains within specification for most automotive reference applications.
Can PDZ3.6BGWX be used as a substitute for PDZ3.6B in legacy designs?
Yes-PDZ3.6BGWX is the tape-and-reel packaging variant (X suffix) of PDZ3.6BGW, sharing identical electrical characteristics, SOD123 package, pinout, and AEC-Q101 qualification. The 'X' denotes standard reel packaging (3000 pcs/reel); no design changes or requalification are required for migration.
What is the non-repetitive peak reverse current (IZSM) and how is it tested?
IZSM is 8.0 A, measured under tp = 100 μs square-wave pulse at Tj = 25 °C prior to surge. This corresponds to the 40 W non-repetitive peak power rating (PZSM = VZ × IZSM ≈ 3.6 V × 8 A). The test verifies robustness against short-duration transients like ESD or inductive switching spikes without permanent parameter shift.
