Product details
Overview
PDZ5.6B-QX from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in surface-mounted 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 4.5 V. It operates in automotive-grade SOD323 (SC-76) package and supports stable reference generation in power supply feedback paths.
For engineers reviewing the PDZ5.6B-QX datasheet, PDZ5.6B-QX pinout, PDZ5.6B-QX application, or PDZ5.6B-QX equivalent, this device is selected for precision low-current voltage clamping, ESD-protected bias networks, and AEC-Q101-compliant regulator references where thermal stability and hard breakdown knee are critical.
Technical Context
This Zener diode functions as a two-terminal shunt voltage reference, operating in reverse breakdown mode with a specified working voltage of 5.48 V to 5.73 V at IZ = 5 mA. Its temperature coefficient is +1.9 mV/K, indicating positive drift with junction temperature - a key design consideration for ambient-stable references.
It exhibits a hard breakdown knee and very low leakage (≤1 μA at VR = 4.5 V), enabling accurate regulation even under light-load conditions. Thermal resistance from junction to solder point is 130 K/W, supporting reliable operation up to 150 °C junction temperature when mounted on FR4 PCB with standard footprint.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.48 V to 5.73 V at IZ = 5 mA - defines precise clamping threshold for feedback or protection circuits |
| Differential Resistance (rdif) | ≤100 Ω at IZ = 5 mA - ensures minimal output voltage variation under load current changes |
| Reverse Leakage (IR) | ≤1 μA at VR = 4.5 V - enables low-quiescent-current biasing without significant error contribution |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports use as low-drop rectifier or polarity indicator in dual-role designs |
| Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C - sets maximum continuous power handling on standard FR4 PCB |
| Temperature Coefficient (SZ) | +1.9 mV/K at IZ = 5 mA - quantifies voltage drift per degree, critical for temperature-compensated references |
| Package | SOD323 (SC-76) - ultra-compact 2-pin surface-mount outline with cathode bar marking, optimized for high-density layouts |
Pinout & Package
SOD323 (SC-76) plastic surface-mounted package with 2 leads; overall dimensions 1.8 mm × 1.35 mm × 0.95 mm; cathode indicated by marking bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V6 | Same 5.6 V nominal, ±5 % tolerance, higher leakage (≤5 μA), SOD523 package | Larger rdif (300 Ω) reduces regulation accuracy in precision feedback | Select only if board space allows SOD523 and ±5 % tolerance is acceptable |
| MMSZ5232BS | 5.6 V nominal, ±5 % tolerance, 150 Ω rdif, SOD123 package | Higher thermal resistance (400 K/W) limits power handling on compact PCBs | Prefer for cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with BZX584-C5V6 and MMSZ5232BS, PDZ5.6B-QX delivers tighter tolerance (±2 %), lower dynamic impedance (100 Ω), and automotive qualification - making it optimal for safety-critical voltage references where regulation stability and reliability are prioritized over cost or footprint flexibility.

FAQ
What is the maximum reverse current the PDZ5.6B-QX can handle in non-repetitive surge conditions?
The PDZ5.6B-QX supports a non-repetitive peak reverse current (IZSM) of 5.5 A under 100 µs square-wave pulse conditions at Tamb = 25 °C. This rating enables transient suppression in conjunction with TVS diodes or as primary clamping in low-energy surge scenarios like load dump spikes in 12 V automotive systems.
How does the +1.9 mV/K temperature coefficient affect its use in precision reference circuits?
A +1.9 mV/K coefficient means the Zener voltage increases by approximately 1.9 mV per degree Celsius rise in junction temperature. At 5.6 V nominal, this yields ~0.034 %/°C drift - acceptable for non-compensated references in ambient-stable applications but requires compensation or selection of complementary TC devices in wide-temperature-range designs.
Can PDZ5.6B-QX be used in forward-bias applications?
Yes - its forward voltage is ≤0.9 V at 10 mA, making it suitable as a low-drop polarity indicator or signal-level clamp in bidirectional interface circuits. However, its forward characteristics are not characterized beyond 100 mA, and it is not optimized for rectification duty; dedicated Schottky diodes are preferred for sustained forward conduction.
Is the SOD323 package compatible with standard reflow soldering profiles?
Yes - Nexperia specifies compatibility with JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) and provides dedicated reflow footprint data (Fig. 9). The SOD323 outline supports peak temperatures up to 260 °C with 30-second dwell time, matching standard lead-free reflow profiles when using recommended solder paste volume and thermal mass management.
