Product details
Overview
PZU5.6B3A,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 reference voltage in low-power analog circuits, power supply feedback loops, and overvoltage protection stages.
For engineers reviewing the PZU5.6B3A,115 datasheet, PZU5.6B3A,115 pinout, PZU5.6B3A,115 application, or PZU5.6B3A,115 equivalent, this device is selected for precision voltage clamping where tight tolerance, low leakage, and hard breakdown knee are required in space-constrained SMT designs.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain a stable reference voltage across its terminals under varying load and temperature conditions. Its 5.6 V nominal Zener voltage is specified at IZ = 5 mA with ±2 % tolerance (B3 series), and exhibits a hard breakdown knee characteristic per AN90031.
Thermal performance is defined by Rth(j-a) = 390 K/W (free air) and Rth(j-sp) = 55 K/W (solder point), enabling reliable operation up to Tj = 150 °C. Non-repetitive surge capability supports 40 W peak reverse power for 100 µs square-wave pulses.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.67 V to 5.92 V at IZ = 5 mA - ensures precise regulation within ±2 % tolerance band |
| Differential Resistance rdif | ≤100 Ω at IZ = 5 mA - minimizes output voltage variation under load current changes |
| Reverse Current IR | ≤40 nA at VR = 0.5 × VZ - enables ultra-low standby power in battery-backed circuits |
| Temperature Coefficient SZ | +2.5 mV/K at IZ = 5 mA - provides predictable, linear drift for compensated reference designs |
| Total Power Dissipation Ptot | 320 mW at Tamb ≤ 25 °C on FR4 PCB - defines continuous DC power handling in standard layout |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 µs - supports transient overvoltage suppression without failure |
| Junction Temperature Range | –55 °C to +150 °C - allows operation in extended industrial environments |
Pinout & Package
The PZU5.6B3A,115 is housed in a SOD323 (SC-76) plastic surface-mount package measuring 1.7 mm × 1.25 mm × 0.95 mm, with 1.3 mm lead pitch and cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to regulated output node; polarity marker determines correct orientation in shunt regulation |
| 2 | Anode | Connected to ground or lower-potential rail; completes reverse-bias path for Zener conduction |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance (B3 series) | Enables tighter regulation accuracy than ±5 % (B-series) parts in feedback networks |
| Hard breakdown knee | Provides sharp, well-defined turn-on for clean voltage clamping without soft saturation |
| Ultra-low reverse leakage (≤40 nA) | Reduces quiescent current error in high-impedance reference dividers and sensor biasing |
| SOD323 footprint compatibility | Supports automated placement and reflow on dense PCBs with 1.3 mm pitch and 1.7 mm length |
| Optimized thermal resistance to solder point (55 K/W) | Improves power derating margin when mounted on thermally enhanced pads |
Applications
| Power Supply Feedback Loop | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Regulating output voltage of a flyback converter using optocoupler-coupled feedback.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX384-B5V6 | Same 5.6 V nominal, ±2 % tolerance, but SOD323 package with higher typical rdif (120 Ω vs. 100 Ω) and higher IR (100 nA vs. 40 nA) | Less suitable for ultra-low-leakage bias networks; acceptable in general-purpose clamping | Select when legacy BOM alignment or distributor stock availability outweighs leakage sensitivity |
| MMSZ5232BS | 5.6 V, ±5 % tolerance (B grade), SOD323, rdif ≤ 150 Ω, IR ≤ 5 µA - looser tolerance and higher leakage | Appropriate only for non-critical voltage references where cost is prioritized over accuracy | Choose for cost-sensitive consumer applications where ±5 % regulation is sufficient |
Compared with BZX384-B5V6 and MMSZ5232BS, PZU5.6B3A,115 offers superior leakage performance and tighter regulation-critical for precision analog signal chains-while maintaining identical SOD323 mounting and thermal behavior.

FAQ
What is the maximum continuous reverse current the PZU5.6B3A,115 can sustain at 25 °C ambient?
The device supports a maximum continuous forward current of 200 mA, but as a Zener diode, its continuous reverse current is limited by power dissipation. At 25 °C ambient on an FR4 PCB, Ptot = 320 mW implies IZ ≤ 57 mA (320 mW ÷ 5.6 V) for steady-state operation without exceeding thermal limits.
How does the B3 tolerance series differ from B1 or B2 in the PZUxBA family?
B3 denotes ±2 % Zener voltage tolerance at IZ = 5 mA, identical to B1 and B2 in specification-but B3 is assigned to specific voltage grades (e.g., 5.6 V, 6.2 V, 6.8 V) per Table 4 marking codes. All three deliver the same accuracy; B3 simply identifies the 5.6 V variant in the ±2 % binning group.
Can PZU5.6B3A,115 be used in place of a 5.1 V Zener for improved noise immunity?
No-Zener voltage is fixed by process and structure. Substituting 5.6 V for 5.1 V alters regulation threshold, potentially causing system malfunction. For noise reduction, select PZU5.1B3A,115 instead, which shares identical construction, leakage, and thermal specs but targets 5.1 V.
Is the SOD323 package of PZU5.6B3A,115 compatible with standard reflow profiles for lead-free assembly?
Yes-the device is qualified for JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The recommended footprint (Fig. 10) uses 0.5 mm solder lands and 0.6 mm solder resist openings, matching IPC-7351B density level 'N' for reliable wetting and void control.
