Product details
Overview
PZU5.6B2A,115 from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOD323 (SC-76) package, rated for 5.6 V nominal working voltage at 5 mA, with 100 Ω maximum differential resistance, 40 nA reverse current at 0.5 mA, and 2.5 mV/K temperature coefficient. It delivers stable voltage reference in low-power analog circuits and overvoltage protection in portable electronics.
For engineers reviewing the PZU5.6B2A,115 datasheet, PZU5.6B2A,115 pinout, PZU5.6B2A,115 application, or PZU5.6B2A,115 equivalent, key selection criteria include tight ±2 % voltage tolerance, low 100 Ω dynamic impedance at regulation current, sub-100 nA leakage, thermal coefficient stability across operating current, and SOD323 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a precise 5.6 V reference under regulated current conditions (IZ = 5 mA). Its hard breakdown knee and low leakage support accurate voltage clamping without significant thermal drift.
The device exhibits a typical temperature coefficient of +2.5 mV/K at IZ = 5 mA, enabling predictable voltage shift over temperature-critical for biasing and sensing circuits where thermal compensation is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 5.6 V at IZ = 5 mA - defines primary regulation point for precision reference applications |
| Voltage Tolerance | ±2 % (B2 series) - ensures 5.49 V to 5.73 V range at 25 °C, supporting tight-signal-chain designs |
| Differential Resistance (rdif) | ≤100 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current (IR) | ≤40 nA at VR = 1.9 V - enables ultra-low standby power in battery-powered voltage monitors |
| Non-repetitive Peak Reverse Current (IZSM) | 5.5 A at tp = 100 μs - supports transient surge suppression in ESD-critical interfaces |
| Total Power Dissipation (Ptot) | 320 mW at Tamb ≤ 25 °C on FR4 PCB - sets continuous DC power limit for thermal design |
| Junction Temperature (Tj) | 150 °C maximum - defines upper thermal boundary for reliability in enclosed environments |
Pinout & Package
SOD323 (SC-76) plastic surface-mount package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; marking bar identifies this terminal for correct PCB orientation |
| 2 | Anode | Connected to ground or lower-potential rail; forms reverse-bias path during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % voltage tolerance (B2 grade) | Enables direct replacement in circuits requiring tighter regulation than standard ±5 % Zeners |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6 | ±5 % tolerance, 150 Ω rdif at 5 mA, 1 µA IR at 1 V | Higher leakage and looser tolerance reduce accuracy in precision references | Select when cost sensitivity outweighs regulation accuracy requirements |
| MMSZ5232B | ±5 % tolerance, 17 Ω rdif at 20 mA, 5 µA IR at 1 V, SOD-123 package | Lower rdif but larger footprint and higher leakage limit use in ultra-low-power designs | Prefer for higher-current regulation where thermal margin allows SOD-123 mounting |
Compared with BZX384-B5V6 and MMSZ5232B, PZU5.6B2A,115 offers superior voltage accuracy and lower leakage for battery-sensitive applications, while its SOD323 size enables denser layouts-making it optimal for compact, precision-regulated systems where ±2 % tolerance and sub-100 nA IR are critical.

FAQ
What is the maximum continuous reverse current for PZU5.6B2A,115 at 25 °C ambient?
The device has no specified maximum continuous reverse current rating; instead, it is limited by total power dissipation of 320 mW at Tamb ≤ 25 °C on an FR4 PCB. At 5.6 V Zener voltage, this corresponds to a maximum steady-state current of approximately 57 mA (320 mW ÷ 5.6 V), assuming full power is allocated to reverse conduction.
How does the ±2 % tolerance (B2) affect circuit calibration in precision analog designs?
The ±2 % tolerance ensures the actual Zener voltage falls between 5.49 V and 5.73 V at 5 mA and 25 °C, reducing initial calibration burden in voltage-reference circuits. When combined with its +2.5 mV/K temperature coefficient, system-level drift remains predictable and compensatable-unlike wider-tolerance Zeners that introduce larger offset uncertainty.
Can PZU5.6B2A,115 be used in place of a 5.1 V Zener for overvoltage protection?
No-its nominal 5.6 V Zener voltage is 10 % higher than 5.1 V, resulting in delayed clamping that may expose downstream components to damaging overvoltage. Substitution requires verifying that the protected circuit's absolute maximum ratings exceed 5.73 V and that timing margins accommodate the higher trip point.
Is the SOD323 package compatible with standard reflow soldering profiles for lead-free assembly?
Yes-the SOD323 package is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260 °C. Nexperia provides recommended solder land patterns (Figure 10) and thermal profiles in the datasheet, confirming compatibility with industry-standard Type 3 and Type 4 solder pastes and conveyorized reflow ovens.
