Product details
Overview
PDZ5.6BF from Nexperia is a single silicon Zener diode designed for low-power voltage regulation in surface-mounted applications, with a nominal Zener voltage of 5.6 V at 5 mA, ±2 % tolerance, 100 Ω maximum differential resistance at 5 mA, 1 μA maximum reverse current at 4.5 V, and 2.5 mV/K temperature coefficient. It operates in general-purpose power supply rail clamping and reference circuits on consumer and industrial PCBs.
For engineers reviewing the PDZ5.6BF datasheet, PDZ5.6BF pinout, PDZ5.6BF application, or PDZ5.6BF equivalent, this device is selected for precision low-current voltage reference, ESD-robust signal line clamping, and compact footprint regulation where thermal resistance to solder point (130 K/W) and SOD323 package compatibility are critical design constraints.
Technical Context
This Zener diode functions as a two-terminal shunt voltage regulator, maintaining stable output voltage across its cathode-anode terminals when reverse-biased above its breakdown threshold. Its hard breakdown knee and low leakage (≤1 μA at VR = 4.5 V) enable accurate low-current referencing without significant bias current error.
The device exhibits a positive temperature coefficient of +1.9 mV/K at IZ = 5 mA, making it suitable for temperature-compensated references when paired with negative-TC components. Its 275 pF capacitance at 0 V and 1 MHz supports moderate-speed transient suppression without high-frequency roll-off.
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 under standard test conditions |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA - determines regulation stiffness and load-induced voltage deviation |
| Reverse Current (IR) | 1 μA max at VR = 4.5 V - ensures minimal standby power loss in high-impedance bias networks |
| Temperature Coefficient (SZ) | +1.9 mV/K at IZ = 5 mA - enables predictable drift compensation in reference designs |
| Forward Voltage (VF) | 0.9 V max at IF = 10 mA - supports use as polarity-sensitive clamp in bidirectional protection schemes |
| Total Power Dissipation (Ptot) | 400 mW at Tamb ≤ 25 °C on FR4 PCB - sets maximum continuous power handling in standard layout |
| Junction-to-Solder-Point Rth | 130 K/W - informs thermal design margin for localized board-level heat sinking |
Pinout & Package
PDZ5.6BF is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.8 mm × 1.35 mm × 0.95 mm, with gull-wing leads and cathode indicated by a marking bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; reverse-bias terminal where Zener breakdown occurs |
| 2 (A) | Anode | Connected to circuit ground or lower-potential rail; completes shunt regulation path |
Key Features
| Feature | Design Value |
|---|---|
| Low dynamic impedance | 100 Ω max at 5 mA - improves regulation accuracy under varying load currents |
| Hard breakdown knee | Sharp transition from non-conduction to Zener conduction - reduces ambiguity in turn-on threshold |
| Very low leakage current | 1 μA max at 4.5 V - minimizes quiescent current in battery-powered or high-impedance reference circuits |
| SOD323 footprint | 1.8 mm × 1.35 mm body - enables high-density placement in space-constrained consumer and IoT PCBs |
| ±2 % voltage tolerance | Tight initial calibration - reduces need for post-assembly trimming in production |

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 | Same 5.6 V nominal, ±5 % tolerance, 150 Ω rdif, SOD523 package (smaller, 1.25 mm × 0.85 mm) | Higher leakage (5 μA), less precise regulation, but superior board area efficiency | Select when PCB real estate is constrained and ±5 % VZ is acceptable |
| MMSZ5232B | 5.6 V nominal, ±5 % tolerance, 17 Ω rdif, SOD123 package (larger, 3.7 mm × 1.6 mm) | Lower impedance, higher Ptot (500 mW), but requires 2.3× more board area | Select when tighter regulation under variable load is required and space permits |
Compared with BZX584-C5V6 and MMSZ5232B, PDZ5.6BF delivers the optimal balance of ±2 % tolerance, 100 Ω impedance, and SOD323 size-making it preferred for cost-sensitive, space-limited designs requiring better than ±5 % regulation without SOD123 footprint penalty.

FAQ
What is the maximum reverse current specification for PDZ5.6BF at 4.5 V?
The maximum reverse current (IR) for PDZ5.6BF is 1 μA when tested at VR = 4.5 V and Tj = 25 °C. This value is confirmed in Table 8 of the Nexperia datasheet Rev. 5 and reflects the device's low-leakage performance critical for high-impedance reference nodes.
Can PDZ5.6BF be used in place of a 5.1 V Zener diode like PDZ5.1B?
No-PDZ5.6BF has a nominal Zener voltage of 5.6 V (5.48–5.73 V), whereas PDZ5.1B is specified at 5.1 V (4.96–5.20 V). Substituting them alters regulation threshold by ~0.5 V, which may cause functional failure in circuits relying on precise voltage thresholds such as reset generators or overvoltage detectors.
What is the thermal resistance from junction to ambient for PDZ5.6BF on a standard FR4 PCB?
The junction-to-ambient thermal resistance (Rth(j-a)) is 340 K/W when mounted on an FR4 PCB with single-sided copper, tin-plated, and standard SOD323 footprint per Table 6. This value assumes free-air convection and defines derating behavior above 25 °C ambient.
Does PDZ5.6BF have automotive qualification?
No-PDZ5.6BF is not automotive-qualified. The Nexperia datasheet explicitly states that unless otherwise indicated, PDZ-B series devices are non-automotive qualified and are not tested to AEC-Q101 or automotive reliability standards. Use in automotive applications requires separate validation and carries no manufacturer warranty.
