Product details
Overview
PDZ13B-QZ from Nexperia is a single Zener diode in SOD323 (SC-76) package, designed for low-power voltage regulation at nominal 13.2 V (IZ = 5 mA), with ±2 % tolerance, 80 Ω max differential resistance at 5 mA, and 0.1 μA max reverse leakage at VR = 10 V. It supports automotive-grade operation per AEC-Q101 and delivers stable clamping in power supply feedback paths and reference circuits.
For engineers reviewing the PDZ13B-QZ datasheet, PDZ13B-QZ pinout, PDZ13B-QZ application, or PDZ13B-QZ equivalent, this device is selected for precision low-current voltage reference, overvoltage protection in sensor interfaces, and biasing in automotive body control modules where thermal stability and small-footprint SMD compatibility are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a hard knee characteristic, enabling sharp voltage regulation at low test currents (IZ = 5 mA). Its temperature coefficient of +9.4 mV/K at IZ = 5 mA ensures predictable drift behavior across automotive ambient ranges (−40 °C to +125 °C).
Thermal resistance from junction to solder point is 130 K/W, and total power dissipation is rated at 400 mW at Tamb ≤ 25 °C on FR4 PCB - enabling reliable operation under derated conditions up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 12.91 V to 13.49 V at IZ = 5 mA - defines precise clamping threshold for feedback or protection circuits |
| Differential Resistance (rdif) | ≤ 80 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation in reference applications |
| Reverse Leakage (IR) | ≤ 0.1 μA at VR = 10 V - enables ultra-low standby current in battery-sensitive systems |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - supports bidirectional use in clamp/steering configurations |
| Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 layout |
| Thermal Resistance (Rth(j-sp)) | 130 K/W - determines junction-to-solder-point temperature rise under steady-state bias |
| AEC-Q101 Qualified | Yes - validated for automotive electronics including engine control units and lighting modules |
Pinout & Package
PDZ13B-QZ uses the SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.35 mm × 0.8 mm footprint, 0.45 mm height, cathode marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; polarity marker (bar) aligns with cathode for correct PCB orientation |
| 2 | Anode (A) | Connected to ground or lower-potential rail; forms reverse-biased junction during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q101 compliant - enables direct use in production automotive ECUs without requalification |
| Low dynamic impedance | 80 Ω max at 5 mA - maintains tight voltage regulation even with modest current changes in feedback loops |
| Hard breakdown knee | Sharp transition into conduction - reduces ambiguity in turn-on behavior for protection circuits |
| Small footprint | SOD323 package - saves board space in dense layouts like ADAS sensor modules and infotainment power rails |
| Low leakage | 0.1 μA max at 10 V reverse bias - preserves battery life in always-on vehicle subsystems |

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 |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal, but ±5 % tolerance and 300 Ω rdif at 5 mA - higher impedance and looser regulation | Acceptable for non-critical biasing; not suitable for precision feedback or AEC-Q101 environments | Select when cost is primary and automotive qualification is unnecessary |
| MMSZ5243B | 13 V nominal, ±5 % tolerance, 30 Ω rdif at 20 mA - lower impedance only at higher current, no AEC-Q101 rating | Requires ≥5 mA operating current for best regulation; lacks automotive reliability validation | Prefer for consumer-grade portable equipment where thermal cycling stress is minimal |
Compared with BZX84-C13 and MMSZ5243B, PDZ13B-QZ offers tighter tolerance (±2 %), lower rdif at low current (80 Ω @ 5 mA), and AEC-Q101 qualification - making it uniquely suited for automotive feedback and safety-critical voltage references where long-term stability and environmental robustness are mandatory.

FAQ
What is the maximum reverse voltage (VR) rating for PDZ13B-QZ before breakdown?
The working voltage (VZ) is specified as 12.91 V to 13.49 V at IZ = 5 mA. The maximum reverse voltage before significant conduction is defined by the breakdown knee - typically ~12.8 V at IZ = 1 mA. At VR = 10 V, reverse leakage is guaranteed ≤0.1 μA, confirming stable blocking behavior below nominal Zener voltage.
Can PDZ13B-QZ be used in parallel for higher power handling?
No - Zener diodes exhibit parameter spread (±2 % VZ tolerance and varying rdif), causing current imbalance and thermal runaway when paralleled. For higher power, use a single higher-rated Zener or implement active regulation with a transistor-based shunt circuit instead.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. Recommended peak temperature is 260 °C for ≤30 seconds, with preheat ramp rate ≤3 °C/s. Figure 9 in the datasheet provides exact solder land dimensions (0.6 mm × 0.5 mm) and paste stencil recommendations.
How does the +9.4 mV/K temperature coefficient affect regulation accuracy over temperature?
At IZ = 5 mA, VZ shifts +9.4 mV per °C rise - resulting in +0.47 V change over a 50 °C range (e.g., 25 °C to 75 °C). This is factored into system-level calibration; for tighter stability, pair with NTC compensation or select a 12 V or 15 V variant with near-zero SZ in the 5–6 V range.
