Product details
Overview
PDZ15BGWJ from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference functions at 15 V nominal Zener voltage (VZ = 14.34–14.98 V @ IZ = 5 mA), ±2 % tolerance (B-series), 80 Ω max differential resistance, and AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the PDZ15BGWJ datasheet, PDZ15BGWJ pinout, PDZ15BGWJ application, or PDZ15BGWJ equivalent, this device serves as a stable, low-capacitance (99 pF @ 1 MHz, VR = 0 V) voltage clamp in power supply feedback loops, overvoltage protection circuits, and analog reference stages where thermal stability (SZ = +11.4 mV/K @ IZ = 5 mA) and low reverse leakage (<0.05 μA @ VR = 12 V) are critical.
Technical Context
This Zener diode operates in reverse breakdown with tightly controlled VZ tolerance and temperature coefficient, enabling accurate voltage referencing across −55 °C to +150 °C ambient range. Its SOD123 package supports high-density SMT layouts while maintaining 365 mW total power dissipation at Tamb ≤ 25 °C and 625 mW derated under enhanced thermal pad conditions.
The device delivers non-repetitive surge capability up to 40 W (tp = 100 μs) and exhibits low forward voltage (VF ≤ 0.9 V @ IF = 10 mA), supporting bidirectional clamping and dual-role use in transient suppression and DC biasing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 15 V - precise regulation point at 5 mA test current, with min/max range 14.34–14.98 V |
| Tolerance | ±2 % - tight B-series tolerance ensures minimal binning and predictable circuit behavior |
| rdif (max) | 80 Ω - low dynamic impedance maintains stable regulation under varying load currents |
| IR (max) | 0.05 μA @ VR = 12 V - ultra-low leakage preserves accuracy in high-impedance reference nodes |
| SZ | +11.4 mV/K @ IZ = 5 mA - positive temperature coefficient enables compensation in multi-device references |
| Cd | 99 pF @ 1 MHz, VR = 0 V - low junction capacitance minimizes signal distortion in RF/precision analog paths |
| Ptot | 365 mW (standard PCB) / 625 mW (enhanced pad) - defines continuous power handling under real-world board thermal conditions |
Pinout & Package
SOD123 surface-mount plastic package: 2.80 mm × 1.70 mm footprint, 1.3 mm height, cathode-marked with bar on top surface; optimized for reflow soldering per IPC-J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | Same 15 V nominal VZ, but ±5 % tolerance and higher rdif (up to 30 Ω), SOT23 package | Lacks AEC-Q101 qualification; not rated for automotive underhood environments | Select when cost sensitivity outweighs precision and automotive compliance requirements |
| MMSZ5245B | 15 V VZ, ±5 % tolerance, 350 mW Ptot, SOD-123 package, but no AEC-Q101 certification | Higher IR (≤0.1 μA) and lower surge rating (25 W) reduce robustness in harsh environments | Prefer for industrial consumer products where extended temperature operation is not required |
Compared with BZX84-C15 and MMSZ5245B, PDZ15BGWJ provides tighter tolerance, lower leakage, higher surge immunity, and automotive qualification-making it the only choice for safety-critical or thermally demanding applications requiring long-term parametric stability.

FAQ
What is the maximum reverse voltage (VR) that PDZ15BGWJ can block before breakdown?
PDZ15BGWJ begins regulating at its nominal Zener voltage of 15 V, with guaranteed breakdown occurring between 14.34 V and 14.98 V at 5 mA test current. It reliably blocks voltages below 12 V with reverse current ≤0.05 μA, making it suitable for pre-regulation clamping where strict leakage control is needed.
How does the +11.4 mV/K temperature coefficient affect circuit design?
The positive temperature coefficient means VZ increases by approximately 11.4 mV per degree Celsius rise in junction temperature. This characteristic allows designers to pair PDZ15BGWJ with negative-coefficient components (e.g., certain op-amp inputs or resistors) to achieve near-zero net drift in reference circuits across −40 °C to +125 °C operating ranges.
Can PDZ15BGWJ be used in parallel for higher power dissipation?
No-Zener diodes must not be paralleled due to mismatched VZ tolerances and thermal runaway risk. For higher power needs, use a single higher-rated device or implement active regulation. PDZ15BGWJ's 365 mW rating assumes standard FR4 PCB mounting; derating is required above 25 °C ambient per its thermal resistance curve.
Is the SOD123 package compatible with standard reflow profiles?
Yes-Nexperia specifies PDZ15BGWJ for reflow soldering only, compliant with IPC-J-STD-020 moisture sensitivity level 1. The recommended profile includes peak temperature ≤260 °C, time above liquidus 60–150 s, and ramp rates within JEDEC limits. Hand soldering is not advised due to thermal stress risks.
