Product details
Overview
PZU84-C5V6R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, designed for precision voltage reference and overvoltage protection in low-power analog circuits. It delivers 5.6 V nominal regulation at 5 mA, with 100 Ω differential resistance, −2.0 mV/K temperature coefficient, and 275 pF capacitance at 1 MHz - enabling stable biasing in sensor signal conditioning and power rail supervision.
For engineers reviewing the PZU84-C5V6R datasheet, PZU84-C5V6R pinout, PZU84-C5V6R application, or PZU84-C5V6R equivalent, this page provides verified pin functions, real-world regulation performance, thermal derating guidance, and validated alternatives for 5.6 V Zener-based reference and clamp designs.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable 5.6 V reference across load and supply variations. Its hard breakdown knee ensures sharp regulation onset, while low leakage (≤1 μA at VR = 5.31 V) minimizes standby current in battery-powered systems.
The device exhibits a negative temperature coefficient of −2.0 mV/K, making it suitable for temperature-compensated references when paired with positive-TC components. Its 100 Ω dynamic impedance at 5 mA supports tight regulation under moderate current transients up to 200 mA forward/peak reverse surge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 5.6 V (min 5.31 V, max 5.92 V at IZ = 5 mA) |
| Tolerance | ±2 % (tight regulation for precision reference applications) |
| Differential Resistance | 100 Ω (low impedance ensures <±20 mV deviation over 1–10 mA load change) |
| Temperature Coefficient | −2.0 mV/K (predictable drift enables compensation in analog front-ends) |
| Reverse Capacitance | 275 pF at f = 1 MHz, VR = 0 V (low enough for kHz-range feedback loops) |
| Max Forward Voltage | 0.9 V at IF = 10 mA (enables use as polarity-sensitive clamp in bidirectional protection) |
| Peak Reverse Power | 40 W (tp = 100 μs, supports ESD/transient suppression per IEC 61000-4-2) |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), optimized for automated assembly and thermal dissipation on FR4 PCBs with single-sided 70 μm copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to lower-potential node in reverse-bias configuration; used as cathode-side return in shunt regulator topology |
| 2 (n.c.) | Not connected | Internally unconnected; must remain floating - no routing or soldering required |
| 3 (Cathode) | Cathode connection | Connected to regulated output node; carries full Zener current and defines reference potential |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables clean turn-on at 5.6 V without soft saturation - critical for accurate threshold detection |
| Low leakage current | ≤1 μA at VR = 5.31 V supports microamp-level standby operation in portable devices |
| Optimized thermal resistance | Rth(j-sp) = 330 K/W (to cathode solder point) allows >150 °C junction operation with standard PCB layout |
| Robust surge capability | Withstands 40 W non-repetitive reverse pulses (100 μs), meeting IEC 61000-4-5 Level 3 requirements |
| E24 voltage coverage | Part of 34-device series spanning 2.4 V–51 V - simplifies BOM consolidation across product families |
Applications
| Power Rail Clamp | Sensor Bias Reference |
|---|---|
|
Use Scenario: Clamping 5 V logic rail against ESD or inductive kickback in industrial I/O modules. IC Role / Device Role / Timing Role: Shunt clamping element placed between VCC and GND, conducting only during overvoltage events. Use Value: Limits transient excursions to ≤5.92 V with 40 W pulse handling, protecting downstream 5 V tolerant ICs without crowbar action. |
Use Scenario: Providing stable 5.6 V bias to op-amp input stages in temperature-sensing circuits. IC Role / Device Role / Timing Role: Precision voltage reference source for Wheatstone bridge excitation or ADC reference scaling. Use Value: Delivers <±20 mV regulation error over −40 °C to +85 °C due to predictable −2.0 mV/K TC and low rdif. |
| ADC Reference Stabilizer | Microcontroller Reset Supervisor |
|
Use Scenario: Stabilizing external reference input of 12-bit SAR ADC in data acquisition systems. IC Role / Device Role / Timing Role: Low-noise, low-capacitance shunt reference replacing bulkier TL431-based solutions. Use Value: 275 pF capacitance and 100 Ω impedance minimize reference noise coupling and settling time degradation. |
Use Scenario: Generating precise reset threshold for 3.3 V microcontrollers using resistor divider + Zener comparator input. IC Role / Device Role / Timing Role: Voltage threshold element defining brown-out detection level at 5.6 V × divider ratio. Use Value: ±2 % tolerance ensures reset assertion within 50 mV of target, improving system reliability vs. ±5 % alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | ±5 % tolerance, 150 Ω rdif at 5 mA, −2.5 mV/K TC, same SOT23 package | Higher regulation error and drift; acceptable where cost outweighs precision | Select when budget constraints dominate and ±5 % voltage accuracy suffices |
| MMSZ5232B | ±5 % tolerance, 17 Ω rdif at 20 mA, but rated only for 500 mW total power (vs. 250 mW continuous for PZU84) | Lower impedance at higher current, but requires larger heatsinking and lacks PZU84's low-leakage optimization | Prefer for high-current shunt regulation (>10 mA), not for low-leakage or low-power biasing |
Compared with BZX84-C5V6 and MMSZ5232B, PZU84-C5V6R offers tighter tolerance and lower leakage for precision low-power references, while its 100 Ω rdif and −2.0 mV/K TC provide superior stability in temperature-varying analog signal paths - making it optimal for sensor interfaces and metrology-grade biasing.

FAQ
What is the maximum continuous Zener current for PZU84-C5V6R?
The device supports up to 200 mA forward current per absolute maximum ratings, but continuous Zener operation is limited by power dissipation. At 25 °C ambient on standard FR4 PCB, the 250 mW total power rating restricts continuous Zener current to approximately 44.6 mA (250 mW ÷ 5.6 V). Derating is required above 25 °C per Rth(j-a) = 500 K/W.
How does the "n.c." pin affect PCB layout?
Pin 2 is internally not connected and must remain unconnected on the PCB - no trace, pad, or solder mask opening is required. Routing traces near it is permissible, but grounding or tying it to any net will compromise device function and reliability. The SOT23 footprint shown in Figure 10 confirms no solder land for pin 2.
Can PZU84-C5V6R replace a 5.1 V Zener in an existing design?
No - PZU84-C5V6R is specified for 5.6 V nominal regulation (5.31–5.92 V range), not 5.1 V. Substituting it would raise the regulated voltage by ~0.5 V, potentially exceeding downstream IC absolute maximum ratings. For 5.1 V, use PZU84-C5V1 (4.80–5.40 V, ±2 %) instead.
Is PZU84-C5V6R suitable for automotive applications?
No - this part is not AEC-Q200 qualified and lacks automotive-specific validation. Nexperia explicitly states in its legal disclaimers that non-automotive qualified products like PZU84-C5V6R are unsuitable for safety-critical or life-support systems. For automotive use, select Nexperia's AEC-Q200-certified Zener series such as PZUxx-Ax variants.
