Product details
Overview
PDZ15B,115 from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in surface-mounted applications. It provides a nominal 15 V Zener voltage at 5 mA test current, with ±2 % tolerance, 80 Ω maximum differential resistance at 5 mA, and 0.05 μA maximum reverse leakage at 11 V, housed in an SOD323 (SC-76) package.
For engineers reviewing the PDZ15B,115 datasheet, PDZ15B,115 pinout, PDZ15B,115 application, or PDZ15B,115 equivalent, this device is selected for precision reference generation, overvoltage clamping in signal conditioning circuits, and low-current bias stabilization where compact size and tight voltage tolerance are critical.
Technical Context
The PDZ15B,115 operates as a two-terminal voltage reference diode with hard breakdown knee and stable regulation across its specified current range (0.5 mA to 20 mA). Its temperature coefficient of +11.4 mV/K at 5 mA enables predictable drift behavior in ambient-temperature-varying environments.
Thermal performance is defined by junction-to-solder-point resistance of 130 K/W and junction-to-ambient resistance of 340 K/W on FR4 PCB, supporting reliable operation up to 150 °C junction temperature with derated power dissipation above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 14.34 V to 14.98 V at IZ = 5 mA - defines precise clamping threshold for 15 V nominal systems |
| Differential Resistance (rdif) | ≤ 80 Ω at IZ = 5 mA - ensures minimal output voltage variation under load changes |
| Reverse Leakage (IR) | ≤ 0.05 μA at VR = 11 V - guarantees negligible standby current in high-impedance bias networks |
| Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C - sets maximum continuous DC or pulsed power handling on standard FR4 PCB |
| Forward Voltage (VF) | 0.9 V at IF = 10 mA - supports use as low-drop rectifier or ESD protection element in bidirectional paths |
| Temperature Coefficient (SZ) | +11.4 mV/K at IZ = 5 mA - enables accurate thermal drift compensation in reference designs |
| Junction Temperature (Tj) | −65 °C to +150 °C - validates suitability for industrial and extended-temperature embedded control modules |
Pinout & Package
PDZ15B,115 is housed in a plastic surface-mounted SOD323 (SC-76) package measuring 1.8 mm × 1.35 mm × 0.95 mm, with cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; polarity must be observed for correct Zener conduction |
| 2 (A) | Anode | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 80 Ω max at 5 mA enables stable voltage reference under varying load conditions |
| Hard breakdown knee | Sharp, well-defined Zener transition improves regulation accuracy and reduces noise sensitivity |
| Tight voltage tolerance | ±2 % at 5 mA supports precision analog circuitry without post-production trimming |
| Ultra-low leakage | 0.05 μA max at 11 V minimizes error in high-impedance feedback or sensing paths |
| SMD-compatible footprint | SOD323 outline allows automated placement and reflow soldering in space-constrained PCBs |
Applications
| Industrial Sensor Signal Conditioning | Microcontroller I/O Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener diode voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C15 (ON Semiconductor) | Same 15 V nominal, ±5 % tolerance, 500 mW Ptot, DO-35 through-hole package | Requires manual assembly or wave soldering; higher thermal resistance limits high-temp reliability | Select when legacy through-hole layout or higher power margin is prioritized over board space |
| MMSZ5245B (Diodes Inc.) | 15 V nominal, ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger than SOD323) | Higher 300 mW derated power at 70 °C ambient vs. PDZ15B's 240 mW - better for warm enclosures | Select when thermal headroom exceeds PCB area constraints and tighter tolerance is not required |
Compared with BZX55C15 and MMSZ5245B, PDZ15B,115 offers superior voltage accuracy (±2 %), smallest footprint (SOD323), and optimized low-current regulation performance - making it preferred for modern miniaturized, precision analog designs.

FAQ
What is the maximum reverse voltage before breakdown for PDZ15B,115?
The PDZ15B,115 exhibits a guaranteed Zener voltage range of 14.34 V to 14.98 V at 5 mA test current. Below 14.34 V, reverse current remains ≤0.05 μA at 11 V; breakdown is sharp and repeatable above this threshold, with no defined "maximum reverse voltage" prior to conduction - it is a true Zener-regulating device, not a TVS.
Can PDZ15B,115 be used in series or parallel configurations?
Series connection is valid for higher composite Zener voltages but requires matched units to avoid current imbalance; parallel use is not recommended due to manufacturing spread in dynamic impedance and breakdown knee characteristics, which causes uneven current sharing and potential thermal runaway.
How does thermal derating affect PDZ15B,115's usable power at 70 °C ambient?
Per the derating curve in Figure 1, at 70 °C ambient, PDZ15B,115's total power dissipation is reduced to approximately 240 mW on standard FR4 PCB. This reflects linear derating from 400 mW at 25 °C, based on a thermal resistance of 340 K/W and 150 °C max junction temperature.
Is PDZ15B,115 suitable for automotive applications?
No - PDZ15B,115 is not automotive-qualified. The datasheet explicitly states "Non-automotive qualified products" and confirms no AEC-Q200 testing or qualification. It is intended for industrial, consumer, and computing applications meeting commercial-grade reliability requirements.
