Product details
Overview
PDZ5.6B-QZ from Nexperia is a single silicon Zener diode designed for precision voltage regulation in low-power circuits, with a nominal Zener voltage of 5.6 V at 5 mA, ±2 % tolerance, 100 Ω maximum differential resistance at 5 mA, and 1 μA maximum reverse leakage at 4.0 V. It operates in automotive-grade SOD323 (SC-76) surface-mount package and supports general-purpose clamping and reference functions in power supply feedback paths.
For engineers reviewing the PDZ5.6B-QZ datasheet, PDZ5.6B-QZ pinout, PDZ5.6B-QZ application, or PDZ5.6B-QZ equivalent, this device is selected for stable low-current voltage reference, overvoltage protection in sensor interfaces, and biasing in automotive control modules where AEC-Q101 qualification and tight Zener voltage tolerance are required.
Technical Context
This Zener diode implements a hard-breakdown junction optimized for low dynamic impedance (100 Ω typ. at IZ = 5 mA) and minimal leakage (1 μA max at VR = 4.0 V), enabling accurate regulation under light-load conditions typical in microcontroller reset circuits and analog sensor references.
Its temperature coefficient of +1.9 mV/K at 5 mA provides predictable positive drift-critical for compensating negative TC components in mixed-signal systems-and its 400 mW total power dissipation rating is defined on FR4 PCB with standard SOD323 footprint per IEC 60134 limiting values.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.48 V to 5.73 V at IZ = 5 mA - defines regulated output range for reference or clamp operation |
| Differential Resistance (rdif) | ≤ 100 Ω at IZ = 5 mA - ensures minimal voltage shift under load variation |
| Reverse Leakage (IR) | ≤ 1 μA at VR = 4.0 V - guarantees low quiescent current in standby-biased circuits |
| Forward Voltage (VF) | ≤ 0.9 V at IF = 10 mA - enables use as low-drop rectifier or polarity indicator |
| Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C on FR4 PCB - sets thermal design margin for board-level layout |
| Thermal Resistance (Rth(j-sp)) | 130 K/W junction-to-solder-point - informs solder-joint thermal path efficiency in reflow profiles |
| AEC-Q101 Qualified | Yes - validated for automotive applications including engine control units and body electronics |
Pinout & Package
PDZ5.6B-QZ uses the SOD323 (SC-76) plastic surface-mount package: 2-terminal, 1.35 mm × 0.8 mm body, 0.45 mm pitch, cathode marked by a bar on the top surface. Thermal performance assumes standard FR4 PCB footprint per Nexperia's reflow land pattern (Fig. 9).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-biased during Zener operation; marking bar identifies this terminal |
| 2 (A) | Anode | Connected to circuit ground or lower-potential rail; forward conduction path when used as rectifier |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 100 Ω max at 5 mA - maintains regulation accuracy across varying load currents in feedback loops |
| Hard breakdown knee | Sharp transition from blocking to conduction - improves noise immunity and threshold repeatability in protection circuits |
| AEC-Q101 qualification | Stress-tested per automotive discrete semiconductor standard - supports deployment in under-hood ECUs without additional qualification |
| ±2 % VZ tolerance | Tighter than standard Zeners (typically ±5 %) - reduces need for post-production trimming in voltage reference designs |
| Low leakage at sub-Zener voltage | 1 μA max at 4.0 V - prevents unintended current draw in battery-powered sleep modes |
Applications
| Automotive Sensor Biasing | Microcontroller Reset Circuit |
|---|---|
|
Use Scenario: Providing stable 5.6 V reference to analog front-end of temperature/pressure sensors in engine control modules. IC Role / Device Role / Timing Role: Zener diode operating in reverse breakdown to fix reference potential relative to ground. Use Value: Enables <1 % measurement error over −40 °C to +125 °C due to predictable +1.9 mV/K TC and low rdif. |
Use Scenario: Generating clean reset signal for ARM Cortex-M microcontrollers during power-up and brown-out events. IC Role / Device Role / Timing Role: Clamping voltage on RC network to ensure deterministic reset pulse width and threshold. Use Value: Hard breakdown knee and 1 μA leakage prevent false resets during low-VCC transients and extend battery life in always-on nodes. |
| USB Port Overvoltage Protection | Industrial I/O Signal Conditioning |
|
Use Scenario: Shunting transient surges on USB VBUS line before reaching downstream USB controller ICs. IC Role / Device Role / Timing Role: Fast-acting shunt element triggered above 5.73 V to divert ESD or load-dump energy. Use Value: 400 mW Ptot and 5.5 A non-repetitive peak surge rating (tp = 100 μs) meet IEC 61000-4-2 Level 4 requirements. |
Use Scenario: Stabilizing 5 V supply rail for 4–20 mA transmitter analog circuitry in PLC input modules. IC Role / Device Role / Timing Role: Low-power voltage regulator maintaining reference stability despite 12–24 V DC input variation. Use Value: 100 Ω rdif limits output deviation to <0.5 % across 0.5–5 mA load range, improving current-loop accuracy. |
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 |
|---|---|---|---|
| BZX584-C5V6 | Same 5.6 V nominal, ±5 % tolerance, 150 mW Ptot, SOD323 package | Lacks AEC-Q101 qualification; higher rdif (200 Ω) and leakage (5 μA) | Acceptable for non-automotive consumer applications where cost sensitivity outweighs precision and reliability |
| MMSZ5232B | 5.6 V nominal, ±5 % tolerance, 500 mW Ptot, SOD123 package | Larger footprint, higher power, no automotive qualification, higher leakage (2.5 μA) | Suitable where board space allows larger package and higher surge handling is prioritized over thermal density |
Compared with PDZ5.6B-QZ, BZX584-C5V6 trades automotive qualification and tighter regulation for lower cost, while MMSZ5232B offers higher power but sacrifices board-area efficiency and AEC compliance-making PDZ5.6B-QZ optimal for space-constrained, safety-critical automotive voltage references.

FAQ
What is the maximum reverse current the PDZ5.6B-QZ can handle during transient events?
The PDZ5.6B-QZ supports a non-repetitive peak reverse current (IZSM) of 5.5 A at tp = 100 μs and Tamb = 25 °C, verified per IEC 61000-4-5 surge testing methodology. This rating enables robust protection against load-dump transients in 12 V automotive systems without derating.
How does the +1.9 mV/K temperature coefficient affect circuit design?
The positive temperature coefficient means VZ increases by ~1.9 mV per Kelvin rise at 5 mA. In mixed-signal systems, this can offset negative TC elements (e.g., bandgap references), allowing passive compensation-designers should model combined TC across −40 °C to +125 °C using Fig. 4 data.
Can PDZ5.6B-QZ be used in forward-bias applications?
Yes: its forward voltage is ≤0.9 V at 10 mA and ≤1.1 V at 100 mA, making it suitable for low-drop polarity indication or signal-level clamping. However, its primary design intent and characterization focus remain reverse-bias Zener operation-not continuous forward conduction.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes: Nexperia specifies a reflow footprint (Fig. 9) with 0.5 mm solder lands and 0.6 mm solder resist openings. The device is qualified for JEDEC J-STD-020D moisture sensitivity level 1 and withstands peak reflow temperatures up to 260 °C for ≤30 seconds without degradation.
