Product details
Overview
PZU84-C5V1R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, delivering 4.80 V to 5.40 V nominal breakdown at IZ = 5 mA, with 250 Ω typical differential resistance and 1.5 μA max reverse current at VR = 1.5 V, used for precision low-power voltage reference and overvoltage clamping in power management circuits.
For engineers reviewing the PZU84-C5V1R datasheet, PZU84-C5V1R pinout, PZU84-C5V1R application, or PZU84-C5V1R equivalent, this page provides verified Zener parameters including VZ tolerance, rdif, temperature coefficient, thermal resistance, and SOT23 terminal mapping - all confirmed from Nexperia's Rev. 4 product data sheet dated 16 August 2024.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with hard knee characteristics optimized for stable regulation at low currents (IZ = 0.5 mA to 5 mA). Its ±2 % tolerance and −2.7 mV/K temperature coefficient at 5 mA enable tight voltage referencing in ambient-temperature-stable designs.
The device features intentional low leakage (≤1.5 μA at VR = 1.5 V) and low dynamic impedance (250 Ω typ. at IZ = 5 mA), supporting noise-sensitive analog rails and precision feedback paths in DC-DC converters and sensor signal conditioning.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 4.80 V to 5.40 V at IZ = 5 mA - defines precise clamping threshold for 5 V rail protection |
| Tolerance | ±2 % - ensures consistent regulation across production batches without post-assembly trimming |
| Differential Resistance rdif | 250 Ω typical at IZ = 5 mA - minimizes output voltage shift under load variation |
| Reverse Current IR | ≤1.5 μA at VR = 1.5 V - enables ultra-low quiescent current in battery-backed circuits |
| Temperature Coefficient SZ | −2.7 mV/K at IZ = 5 mA - quantifies VZ drift per °C for thermal error budgeting |
| Total Power Dissipation Ptot | 250 mW on FR4 PCB - sets maximum continuous power handling in standard layout |
| Junction-to-Ambient Rth(j-a) | 500 K/W - determines steady-state temperature rise above ambient at rated power |
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 placement and reflow soldering per IPC-7351 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in reverse-regulation configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or thermal pad connection |
| 3 | Cathode (K) | Reverse-bias input terminal; ties to regulated voltage node or surge path in clamp topology |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables sharp, predictable conduction onset at VZ - critical for accurate overvoltage detection |
| Low leakage current | ≤1.5 μA at VR = 1.5 V - preserves battery life in always-on monitoring circuits |
| Stable ±2 % VZ tolerance | Eliminates need for external calibration in 5 V reference applications |
| Optimized low-current regulation | Specified performance down to IZ = 0.5 mA - supports microamp-level bias networks |
| SOT23 footprint compatibility | Matches JEDEC TO-236AB standard - enables drop-in replacement in existing layouts |
Applications
| Power Supply Voltage Reference | ESD Protection Clamp |
|---|---|

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-C5V1 | Same SOT23 package, ±5 % tolerance, 400 Ω rdif at 5 mA, higher leakage (≤5 μA at VR = 1.5 V) | Acceptable where cost sensitivity outweighs precision; less suitable for sub-μA bias networks | Select when ±5 % VZ and higher dynamic impedance are acceptable for non-critical references |
| MMSZ5231B | SOD-123 package, ±5 % tolerance, 17 Ω rdif at 20 mA, but requires ≥10 mA for spec compliance | Better regulation at high current, but unsuitable for low-IZ operation (<1 mA) due to soft knee | Choose only if design operates consistently ≥10 mA and board space allows larger SOD-123 footprint |
Compared with BZX84-C5V1 and MMSZ5231B, PZU84-C5V1R delivers tighter tolerance, lower leakage, and verified low-current regulation - making it optimal for precision, low-power, and space-constrained applications where SOT23 fit and ±2 % stability are mandatory.

FAQ
What is the maximum continuous reverse power dissipation for PZU84-C5V1R?
The maximum continuous reverse power dissipation is 250 mW at Tamb = 25 °C on a standard FR4 PCB with single-sided 70 μm copper. This value decreases linearly above 25 °C at a rate defined by Rth(j-a) = 500 K/W, reaching zero derated power at Tj = 150 °C.
Does PZU84-C5V1R have a connected pin 2?
No - pin 2 is explicitly marked "n.c." (not connected) in Nexperia's official pinning diagram and must remain electrically floating. It is not internally bonded and has no function; connecting it risks mechanical stress or unintended parasitic coupling.
How does the temperature coefficient affect regulation accuracy over temperature?
With a specified SZ of −2.7 mV/K at IZ = 5 mA, VZ decreases by approximately 2.7 mV per °C rise. Over a −40 °C to +85 °C range, this contributes ±338 mV drift - but combined with ±2 % initial tolerance, total VZ variation remains within ±4.8 % of nominal 5.1 V.
Can PZU84-C5V1R be used in forward-bias applications?
Yes - its forward voltage is specified as ≤0.9 V at IF = 10 mA, making it usable as a low-drop silicon diode in level-shifting or polarity-protection roles. However, its primary design intent and characterization are for reverse-bias Zener operation; forward parameters are secondary specifications.
