Product details
Overview
PDZ13B-QF from Nexperia is a single Zener diode in SOD323 (SC-76) package, designed for precision voltage regulation at 13.2 V nominal working voltage with ±2 % tolerance, 80 Ω max differential resistance at IZ = 5 mA, and 0.1 μA max reverse current at VR = 10 V - used in automotive power rail clamping and low-power reference circuits.
For engineers reviewing the PDZ13B-QF datasheet, PDZ13B-QF pinout, PDZ13B-QF application, or PDZ13B-QF equivalent, this device is selected for AEC-Q101-qualified automotive voltage stabilization where compact size, hard breakdown knee, and stable temperature coefficient (9.4 mV/K at IZ = 5 mA) are critical.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its cathode-anode terminals. Its 13.2 V nominal Zener voltage is specified at IZ = 5 mA, with a tight 12.91 V to 13.49 V min/max range and a typical temperature coefficient of +9.4 mV/K - indicating positive drift with junction temperature rise.
It delivers 400 mW total power dissipation on FR4 PCB with standard footprint, supported by thermal resistance Rth(j-a) = 340 K/W and Rth(j-sp) = 130 K/W, enabling reliable operation up to Tj = +150 °C in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.91 V to 13.49 V at IZ = 5 mA - defines precise clamping threshold for 12 V system rails |
| Differential Resistance rdif | ≤ 80 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation |
| Reverse Current IR | ≤ 0.1 μA at VR = 10 V - guarantees ultra-low leakage in standby modes |
| Power Dissipation Ptot | 400 mW at Tamb ≤ 25 °C - supports continuous regulation in compact SMD layouts |
| Temperature Coefficient SZ | +9.4 mV/K at IZ = 5 mA - enables predictable voltage drift compensation in thermal design |
| Forward Voltage VF | 0.9 V at IF = 10 mA - confirms low-loss conduction during forward bias events |
| Junction Temperature Tj | +150 °C maximum - validates suitability for under-hood automotive electronics |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package: 2-terminal, 1.35 mm × 0.8 mm body, 0.45 mm pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-bias terminal where Zener breakdown occurs |

Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive applications including engine control units and body electronics |
| Hard breakdown knee | Sharp, well-defined Zener transition enables accurate voltage clamping without soft saturation |
| Low dynamic impedance | 80 Ω max at 5 mA ensures stable regulation under dynamic load transients |
| Ultra-low leakage | 0.1 μA max at 10 V reverse bias minimizes quiescent current in battery-powered systems |
| Small SOD323 footprint | 1.35 mm × 0.8 mm area saves PCB space in dense automotive ECUs and ADAS modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | Same 13 V nominal, but ±5 % tolerance, 350 mW Ptot, no AEC-Q101 qualification | Limited to commercial-grade consumer products; unsuitable for automotive deployment | Select when cost sensitivity outweighs automotive compliance and tighter tolerance needs |
| MMSZ5243B | 13 V nominal, ±5 % tolerance, 500 mW Ptot, SOD-123 package (larger footprint) | Higher power handling but lacks AEC-Q101 and exhibits softer breakdown knee | Prefer for industrial power supplies requiring >400 mW dissipation and less stringent thermal constraints |
Compared with BZX84-C13 and MMSZ5243B, PDZ13B-QF offers superior automotive qualification, tighter ±2 % voltage tolerance, and optimized low-current Zener characteristics - making it the only choice for AEC-compliant 13 V reference and clamping in space-constrained ECUs.

FAQ
What is the exact Zener voltage range for PDZ13B-QF at 5 mA test current?
The guaranteed Zener voltage range is 12.91 V to 13.49 V when measured at IZ = 5 mA and Tj = 25 °C, per Table 8 of the official Nexperia datasheet Rev. 2. This 580 mV span reflects the ±2 % tolerance around the nominal 13.2 V rating.
Is PDZ13B-QF suitable for use in reflow soldering processes?
Yes - the SOD323 package is qualified for standard lead-free reflow profiles. Nexperia specifies a recommended reflow footprint in Figure 9, with 0.5 mm solder land width and 0.6 mm solder resist opening, aligned to JEDEC J-STD-020 moisture sensitivity level 1.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With a typical SZ of +9.4 mV/K at IZ = 5 mA, PDZ13B-QF's Zener voltage increases ~1.13 V from −40 °C to +125 °C. System designers must account for this +8.5 % drift in precision reference applications, especially when paired with uncalibrated ADCs.
Can PDZ13B-QF replace PDZ13B in existing designs?
Yes - PDZ13B-QF is the AEC-Q101-qualified variant of PDZ13B, sharing identical electrical specs, SOD323 package, and marking code "ZJ". The "QF" suffix denotes automotive qualification; no layout or schematic changes are required for drop-in replacement in new automotive designs.
