Nexperia USA Inc. PDZ3.0BGWX

Overview

PDZ3.0BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications at nominal 3.0 V with ±2 % tolerance (B-series), 95 Ω max differential resistance at I_Z = 5 mA, and AEC-Q101 qualification for automotive environments.

For engineers reviewing the PDZ3.0BGWX datasheet, PDZ3.0BGWX pinout, PDZ3.0BGWX application, or PDZ3.0BGWX equivalent, this device supports stable low-voltage clamping in power supply feedback loops, ESD protection circuits, and sensor biasing 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 nominal working voltage of 3.0 V at I_Z = 5 mA, exhibiting a temperature coefficient of −2.1 mV/K and reverse current ≤10 μA at V_R = 2.85 V (0.5×V_Z,min). Its junction-to-ambient thermal resistance is 340 K/W on standard FR4 PCB.

The device delivers non-repetitive peak reverse power dissipation up to 40 W (t_p = 100 μs), while maintaining total DC power dissipation ≤365 mW at T_amb ≤ 25 °C - enabled by its SOD123 thermally optimized plastic package with cathode-side thermal pad.

FAQ

What is the maximum continuous reverse current the PDZ3.0BGWX can sustain at 25 °C?

The PDZ3.0BGWX sustains up to 115 mA continuous reverse current at 25 °C ambient, calculated from its 365 mW total power dissipation rating and nominal 3.0 V Zener voltage (I_Z,max = P_tot/V_Z ≈ 365 mW / 3.0 V). Derating applies above 25 °C per the 340 K/W thermal resistance curve.

Does the PDZ3.0BGWX require a heatsink for operation at 250 mW?

No heatsink is required at 250 mW on standard FR4 PCB with single-sided 1 cm² cathode copper pad, as the device's junction-to-solder-point thermal resistance is 200 K/W - resulting in only ~50 K temperature rise (250 mW × 200 K/W), well within the 150 °C T_j limit.

How does the −2.1 mV/K temperature coefficient affect regulation accuracy over temperature?

At a 100 °C temperature swing (−40 °C to +60 °C), the −2.1 mV/K coefficient causes ~210 mV total Zener voltage shift. Combined with ±2 % initial tolerance (±60 mV), worst-case regulation spans 2.79–3.21 V - sufficient for most 3.3 V system monitoring where ±3 % margin is acceptable.

Can PDZ3.0BGWX replace PDZ3.0B in existing designs?

Yes - PDZ3.0BGWX is a direct replacement for PDZ3.0B, sharing identical electrical specifications, SOD123 package, pinout, and AEC-Q101 qualification. The "X" suffix denotes tape-and-reel packaging per EIA-481 standard, with no functional or thermal differences.
