Nexperia USA Inc. PDZ3.6BGWJ

Overview

PDZ3.6BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at nominal 3.6 V with ±2 % tolerance (B-series), 90 Ω max differential resistance at I_Z = 5 mA, and AEC-Q101 qualification for automotive-grade reliability. It operates with reverse current as low as 5 μA at V_R = 1 V and supports transient suppression up to 40 W non-repetitive peak power.

For engineers reviewing the PDZ3.6BGW datasheet, PDZ3.6BGW pinout, PDZ3.6BGW application, or PDZ3.6BGW equivalent, this device is selected for stable low-voltage reference generation, overvoltage clamping in sensor interfaces, and ESD-robust biasing in automotive control modules where tight Zener voltage tolerance and thermal stability are critical.

Technical Context

The PDZ3.6BGW implements a silicon planar Zener junction optimized for stable breakdown at 3.60–3.85 V under 5 mA test current, with temperature coefficient of −2.4 mV/K enabling predictable drift compensation in ambient ranges from −55 °C to +150 °C. Its low 5 μA reverse leakage at 1 V ensures minimal standby power loss in always-on circuits.

Thermal design is supported by R_th(j-a) = 340 K/W (free air) and R_th(j-sp) = 200 K/W (solder point), allowing reliable operation at P_tot ≤ 365 mW on standard FR4 PCBs. The SOD123 footprint enables high-density placement while maintaining adequate thermal relief via cathode pad area.

FAQ

What is the maximum continuous reverse current the PDZ3.6BGW can sustain at 25 °C ambient?

The PDZ3.6BGW has a total power dissipation limit of 365 mW at T_amb ≤ 25 °C. At its nominal Zener voltage of 3.6 V, this corresponds to a maximum continuous reverse current of approximately 101 mA (365 mW ÷ 3.6 V). Operation above this current requires derating per the thermal resistance curve and PCB copper area.

How does the −2.4 mV/K temperature coefficient affect regulation accuracy over temperature?

With a −2.4 mV/K coefficient, the Zener voltage decreases by 2.4 mV per Kelvin rise. Over a 100 K range (e.g., −40 °C to +60 °C), this yields a total drift of −240 mV from nominal 3.6 V-approximately −6.7 %. This is fully characterized and predictable, enabling compensation in closed-loop systems or acceptable for applications tolerating ±7 % variation.

Can PDZ3.6BGW replace PDZ3.6B in existing designs?

Yes-PDZ3.6BGW is the automotive-qualified (AEC-Q101) variant of PDZ3.6B, sharing identical electrical specifications, SOD123 package, pinout, and marking (B5). The "GW" suffix denotes enhanced process control and qualification; no layout or schematic changes are required for drop-in replacement in new or legacy automotive designs.

What is the significance of the 500 μA reverse current specification at 1 mA test condition?

The "500 μA @ 1 mA" entry in Table 8 indicates the maximum reverse current measured at V_R = 1 V (not at rated Zener voltage). This low leakage value confirms excellent junction integrity and low standby power consumption-critical for always-on circuits like real-time clock backup or sensor bias rails where sub-μA currents impact battery life.
