Product details
Overview
PDZ5.6B-QF from Nexperia is a single Zener diode in SOD323 (SC-76) package, designed for low-power voltage regulation at nominal 5.6 V with ±2 % tolerance, 100 Ω dynamic impedance at 5 mA, and 1 μA reverse leakage at 2 V. It delivers stable reference voltage in automotive power supply rails, ECU bias networks, and sensor interface circuits.
For engineers reviewing the PDZ5.6B-QF datasheet, PDZ5.6B-QF pinout, PDZ5.6B-QF application, or PDZ5.6B-QF equivalent, this device supports AEC-Q101-compliant designs requiring tight voltage tolerance, low thermal resistance (130 K/W junction-to-solder point), and hard breakdown knee behavior under transient load conditions.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable 5.48–5.73 V working voltage at 5 mA test current, with temperature coefficient of +1.9 mV/K enabling predictable drift compensation in ambient ranges up to +150 °C junction temperature.
Its 100 Ω differential resistance at IZ = 5 mA and 2.5 Ω at IZ = 0.5 mA ensures minimal output variation across load changes, while 275 pF capacitance at 0 V and 1 MHz supports stable operation in low-frequency regulation without parasitic oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 5.48–5.73 V at IZ = 5 mA - defines precise clamping threshold for 5.6 V nominal rail regulation |
| Differential Resistance (rdif) | 100 Ω at IZ = 5 mA - limits output voltage shift under ±1 mA load variation |
| Reverse Leakage (IR) | 1 μA at VR = 2 V - ensures minimal standby current in battery-backed circuits |
| Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C - supports continuous regulation in compact PCB layouts |
| Thermal Resistance (Rth(j-sp)) | 130 K/W junction-to-solder point - enables reliable thermal transfer to copper pour on FR4 |
| Temperature Coefficient (SZ) | +1.9 mV/K at IZ = 5 mA - provides positive drift for offset cancellation in dual-diode references |
| Capacitance (Cd) | 275 pF at f = 1 MHz, VR = 0 V - avoids signal coupling issues in analog sensor front-ends |
Pinout & Package
SOD323 (SC-76) surface-mount plastic package with 2 leads, 1.35 mm × 0.8 mm footprint, 0.45 mm height, and cathode-marked bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX584-C5V6 | 5.6 V ±5 % tolerance, 150 Ω rdif at 5 mA, SOD523 package | Higher tolerance and impedance reduce accuracy in precision biasing | Select when cost sensitivity outweighs voltage stability requirements |
| MMSZ5232BS | 5.6 V ±5 %, 17 Ω rdif at 20 mA, SOD123 package | Larger footprint and higher test current limit use in low-current sensor nodes | Select when lower impedance is critical and board space permits larger package |
Compared with BZX584-C5V6 and MMSZ5232BS, PDZ5.6B-QF offers tighter ±2 % tolerance and optimized 100 Ω impedance at 5 mA-making it preferable for automotive-grade bias networks where low-current stability and AEC-Q101 compliance are mandatory.

FAQ
What is the maximum continuous reverse current rating for PDZ5.6B-QF?
The PDZ5.6B-QF has no specified continuous reverse current rating because it operates in Zener breakdown mode; its safe operating limit is defined by power dissipation. At 25 °C ambient, maximum reverse current is 400 mW ÷ 5.6 V ≈ 71 mA. Derating applies per Figure 1's power curve above 25 °C.
How does the +1.9 mV/K temperature coefficient affect circuit performance?
The positive temperature coefficient means VZ increases by 1.9 mV per Kelvin rise in junction temperature. This enables predictable drift compensation-for example, pairing with a negative-coefficient thermistor or using in dual-diode configurations to achieve near-zero net drift over −40 °C to +125 °C.
Can PDZ5.6B-QF be used in forward-bias applications like standard diodes?
Yes, but not optimally: its forward voltage is 0.9 V at 10 mA and 1.1 V at 100 mA. While functional as a rectifier, its SOD323 package and Zener-optimized doping make it less efficient than dedicated switching diodes like BAS16 for high-speed or high-current forward conduction.
Is the SOD323 footprint compatible with automated reflow soldering processes?
Yes-the official Nexperia reflow footprint (Figure 9) specifies 0.5 mm × 0.6 mm solder lands with 0.95 mm pad pitch, fully compatible with IPC-7351 Class B standards and standard stencil thicknesses (125–150 μm), supporting >99.8 % first-pass yield in high-volume SMT lines.
