Nexperia USA Inc. PDZ3.0BGWJ

Overview

PDZ3.0BGW from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation at 3.0 V nominal Zener voltage with ±2 % tolerance (B-series), 95 Ω max differential resistance at I_Z = 5 mA, and AEC-Q101 qualification for automotive-grade reliability. It delivers stable clamping in low-power biasing and reference circuits.

For engineers reviewing the PDZ3.0BGW datasheet, PDZ3.0BGW pinout, PDZ3.0BGW application, or PDZ3.0BGW equivalent, key selection criteria include its 3.0 V Zener voltage tolerance, 10 μA reverse current at V_R = 2.4 V, −2.1 mV/K temperature coefficient, and SOD123 thermal performance (R_th(j-a) = 340 K/W).

Technical Context

This Zener diode operates in reverse breakdown mode to maintain a stable reference voltage under varying load and temperature conditions. Its design supports precise DC biasing and overvoltage protection in space-constrained SMD layouts.

With a 2.85 V to 3.07 V Zener voltage range at I_Z = 5 mA, it achieves tight regulation while maintaining low dynamic impedance (≤95 Ω) and predictable thermal drift (−2.1 mV/K). The device is rated for 365 mW total power dissipation on standard FR4 PCBs.

FAQ

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

The PDZ3.0BGW is rated for a maximum continuous forward current of 200 mA, but as a Zener diode, its reverse conduction is defined by power dissipation limits. At 25 °C ambient, it sustains up to 121 mA reverse current continuously (365 mW ÷ 3.0 V), assuming ideal heat sinking. Derating applies above 25 °C per the thermal resistance curve.

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

The −2.1 mV/K coefficient means the Zener voltage decreases by 2.1 mV per Kelvin rise in junction temperature. Over a 100 K range (e.g., −40 °C to +60 °C), this results in ~210 mV total drift. When combined with its ±2 % initial tolerance (±60 mV), worst-case total variation is ±270 mV-critical for sub-1 % reference designs requiring external compensation.

Can PDZ3.0BGW replace PDZ3.3BGW in an existing 3.3 V reference design?

No-PDZ3.0BGW has a nominal Zener voltage of 3.0 V (2.85–3.07 V), while PDZ3.3BGW is 3.3 V (3.32–3.53 V). Substituting would reduce reference voltage by ~9 %, potentially causing undervoltage lockout or ADC scaling errors. The 0.3 V difference exceeds typical design margins and requires circuit recalibration.

Is the SOD123 package compatible with standard reflow soldering profiles for lead-free assembly?

Yes-the PDZ3.0BGW's SOD123 package is qualified for lead-free reflow per J-STD-020. Its recommended profile includes peak temperature ≤260 °C, time above liquidus 60–150 s, and ramp rates within 3 °C/s. The cathode pad layout matches IPC-7351B standard footprint dimensions (4.18 mm × 1.11 mm), ensuring compatibility with automated placement and inspection.
