Product details
Overview
PDZ13BZ from Nexperia is a single low-power Zener diode in SOD323 (SC-76) surface-mount package, designed for precision voltage regulation at 13.2 V nominal working voltage (IZ = 5 mA), with ±2 % tolerance, 80 Ω max differential resistance at IZ = 5 mA, and 0.1 μA max reverse leakage at VR = 10 V. It operates in general-purpose power supply rail clamping and reference applications requiring stable low-current regulation.
For engineers reviewing the PDZ13BZ datasheet, PDZ13BZ pinout, PDZ13BZ application, or PDZ13BZ equivalent, this device is selected for compact voltage reference design, ESD-protected bias networks, and low-power analog circuit stabilization where thermal resistance (Rth(j-a) = 340 K/W) and hard breakdown knee behavior are critical to performance consistency.
Technical Context
This Zener diode functions as a two-terminal shunt voltage regulator, maintaining a stable reverse-biased breakdown voltage across its cathode-anode terminals under controlled current conditions. Its operation relies on avalanche breakdown mechanism above 6 V, delivering a temperature coefficient of +9.4 mV/K at IZ = 5 mA and exhibiting hard knee characteristics per Nexperia's characterization.
The device is rated for 400 mW total power dissipation at Tamb ≤ 25 °C on FR4 PCB with standard footprint, derating linearly above that ambient temperature. Its junction-to-ambient thermal resistance (340 K/W) and junction-to-solder-point resistance (130 K/W) define thermal limits in real-world board layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13.2 V at IZ = 5 mA - defines precise regulation point for low-current reference circuits |
| Zener Voltage Range | 12.91 V to 13.49 V - ensures ±2 % tolerance compliance for production binning |
| Differential Resistance | ≤ 80 Ω at IZ = 5 mA - determines output impedance and regulation sensitivity to load current changes |
| Reverse Leakage Current | ≤ 0.1 μA at VR = 10 V - enables ultra-low quiescent power consumption in standby bias networks |
| Forward Voltage | ≤ 0.9 V at IF = 10 mA - supports reliable anode-cathode conduction during forward transient events |
| Power Dissipation | 400 mW at Tamb = 25 °C - sets maximum continuous operating limit on standard FR4 PCB |
| Thermal Resistance | 340 K/W junction-to-ambient - quantifies self-heating impact on voltage stability under sustained load |
Pinout & Package
PDZ13BZ uses the SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.35 mm body size, 0.45 mm nominal height, cathode marked by a bar on the top surface. Mounting requires reflow-compatible solder lands per Figure 9 (0.6 mm × 0.5 mm pads, 2.1 mm center-to-center pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated voltage node; polarity marking bar identifies this terminal on package top |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Sharp, well-defined Zener transition enables predictable turn-on without soft saturation region |
| Low dynamic impedance | 80 Ω max at 5 mA ensures minimal voltage shift under small-signal load variations |
| Ultra-low leakage | 0.1 μA max at 10 V reverse bias preserves battery life in always-on sensing nodes |
| SOD323 footprint | Compact 1.7 × 1.35 mm outline supports high-density PCB layouts in space-constrained modules |
| ±2 % voltage tolerance | Reduces need for post-assembly trimming in factory calibration of analog references |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C13 | Same 13 V nominal, but ±5 % tolerance and higher rdif (100 Ω); TO-236AB package | Larger footprint; less precise regulation; suitable for non-critical clamping | Select when cost priority outweighs voltage accuracy and board space constraints |
| MMSZ5242B | 13 V nominal, ±5 % tolerance, 100 Ω rdif, SOD-123 package (larger than SOD323) | Higher thermal resistance (400 K/W); lower power rating (350 mW) | Choose if legacy SOD-123 footprint compatibility is required over miniaturization |
Compared with BZX584-C13 and MMSZ5242B, PDZ13BZ delivers tighter voltage tolerance (±2 % vs ±5 %), lower dynamic impedance (80 Ω vs ≥100 Ω), and superior board-area efficiency via SOD323, making it optimal for precision, space-constrained designs where regulation stability is critical.

FAQ
What is the maximum reverse current PDZ13BZ can handle before damage?
PDZ13BZ has a non-repetitive peak reverse current (IZSM) rating of 2.5 A at tp = 100 µs and Tamb = 25 °C, verified per IEC 60134 absolute maximum ratings. This surge capability allows brief transient suppression without degradation, provided average power remains within 400 mW derated limits.
Does PDZ13BZ require a series resistor in typical Zener regulator configurations?
Yes - a current-limiting resistor is mandatory to set IZ between 1 mA and 20 mA, ensuring stable regulation while staying within Ptot = 400 mW. For 13.2 V output from a 15 V source, a 180 Ω resistor establishes ~10 mA bias, balancing regulation accuracy and thermal margin.
How does the +9.4 mV/K temperature coefficient affect long-term voltage stability?
The positive temperature coefficient means VZ increases by ~9.4 mV per °C rise in junction temperature. At 85 °C ambient (assuming ΔTj ≈ 30 °C), VZ shifts +0.28 V - still within the 12.91–13.49 V specification band, preserving functional margin in most industrial environments.
Can PDZ13BZ be used in place of PDZ12B or PDZ15B without circuit redesign?
No - although all share SOD323 packaging, their Zener voltages differ significantly (12 V, 13.2 V, 15 V). Substitution alters regulation point by >10 %, risking overvoltage or undervoltage in sensitive analog circuits; resistor values and system tolerances must be re-evaluated for each variant.
