Product details
Overview
PDZ15BGWX from Nexperia is a single Zener diode in SOD123 package, designed for precision voltage regulation and reference applications with nominal Zener voltage of 15 V at 5 mA, ±2 % tolerance (B-series), 80 Ω maximum differential resistance, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDZ15BGWX datasheet, PDZ15BGWX pinout, PDZ15BGWX application, or PDZ15BGWX equivalent, this device supports stable low-power voltage clamping, ESD-robust biasing, and temperature-compensated reference generation in space-constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified working voltage of 14.34 V to 14.98 V at IZ = 5 mA, exhibiting a temperature coefficient of +11.4 mV/K and reverse current ≤ 0.05 μA at VR = 11.0 V. Its non-repetitive peak reverse power dissipation is rated at 40 W for 100 μs pulses.
The device features low thermal resistance - Rth(j-sp) = 50 K/W to solder point - and is optimized for surface-mount reflow assembly on FR4 PCBs with standard SOD123 footprint. It delivers stable regulation under ambient temperatures from −55 °C to +150 °C.

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 | ±5 % tolerance, SOT23 package, 300 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer electronics; unsuitable for automotive deployment | Select when cost sensitivity outweighs precision and qualification requirements |
| MMSZ5245B | ±5 % tolerance, SOD123 package, 500 mW Ptot, no AEC-Q101, higher leakage (≤5 μA at 12 V) | Higher power handling but inferior leakage and temperature stability | Prefer only if higher continuous dissipation is required and automotive compliance is not needed |
Compared with BZX84-C15 and MMSZ5245B, PDZ15BGWX offers tighter tolerance, lower leakage, and automotive qualification - making it the sole choice for safety-critical or temperature-stable regulation where long-term parametric consistency matters.

FAQ
What is the maximum continuous forward current rating for PDZ15BGWX?
The PDZ15BGWX is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 200 mA per datasheet limiting values. However, forward conduction is not its functional mode - sustained forward bias exceeds design intent and risks thermal overstress without providing regulation benefit.
Does PDZ15BGWX require a series current-limiting resistor in all applications?
Yes - a series resistor is mandatory to limit reverse current to within the device's power and thermal limits. For example, at 15 V regulation with 12 V supply, a minimum 100 Ω resistor limits worst-case current to ~30 mA, keeping power dissipation below 365 mW and junction temperature within 150 °C.
How does the +11.4 mV/K temperature coefficient affect circuit performance?
This positive temperature coefficient means VZ increases by ~11.4 mV per °C rise in junction temperature. In precision references, it must be compensated - e.g., by pairing with a negative-TC component or selecting adjacent Zener voltages whose coefficients cancel across operating range.
Can PDZ15BGWX replace older PDZ15B variants without layout changes?
Yes - PDZ15BGWX shares identical SOD123 mechanical dimensions, pinout, thermal footprint, and electrical specifications with prior PDZ15B versions. The 'X' suffix denotes tape-and-reel packaging variant; board-level compatibility is fully maintained per Nexperia's ordering information table.
