Product details
Overview
PZU84-B10R from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, delivering 10 V nominal regulation at 5 mA with 60 Ω differential resistance and 7 mV/K temperature coefficient. It operates across −55 °C to +150 °C ambient, supports 250 mW steady-state dissipation, and serves as a precision reference in low-power analog supply rails and voltage clamp circuits.
For engineers reviewing the PZU84-B10R datasheet, PZU84-B10R pinout, PZU84-B10R application, or PZU84-B10R equivalent, this page provides verified Zener parameters, validated SOT23 terminal mapping, confirmed thermal resistance (330 K/W junction-to-solder-point), documented leakage behavior per AN90031, and cross-referenced alternatives for 10 V regulation with tight tolerance.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable DC reference generation. Its 60 Ω dynamic impedance at IZ = 5 mA ensures minimal output voltage variation under load shifts, while the 7 mV/K temperature coefficient enables predictable drift compensation in temperature-sensitive circuits.
The device features intentional low leakage current (<0.1 μA at VR = 10 V) and 110 pF capacitance at 1 MHz, making it suitable for noise-sensitive analog front-ends. Its non-repetitive peak reverse power rating of 40 W (100 μs pulse) supports transient overvoltage clamping without degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 10 V nominal at IZ = 5 mA; ±2 % tolerance ensures 9.8–10.2 V regulation window in production |
| Differential Resistance rdif | 60 Ω max at IZ = 5 mA; limits output voltage shift to ≤300 mV under ±5 mA load change |
| Temperature Coefficient SZ | 7 mV/K typical; predictable linear drift allows accurate thermal error budgeting in reference designs |
| Reverse Current IR | <0.1 μA at VR = 10 V; minimizes quiescent current draw in battery-powered voltage monitors |
| Total Power Dissipation Ptot | 250 mW at Tamb = 25 °C on FR4 PCB; defines maximum continuous bias current of 25 mA at 10 V |
| Junction-to-Solder-Point Rth(j-sp) | 330 K/W; enables thermal design margin calculation for cathode pad copper area in layout |
| Capacitance Cd | 110 pF at f = 1 MHz, VR = 0 V; sets upper bandwidth limit for AC-coupled clamp applications |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, single-sided 70 μm tin-plated copper footprint on FR4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node in reverse-bias regulation configuration |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating-no PCB trace or thermal pad connection permitted |
| 3 | Cathode (K) | Reverse-bias input terminal; ties to regulated voltage node and provides primary thermal path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 10 V reference circuits without recalibration or resistor trimming |
| Hard breakdown knee | Ensures monotonic, low-hysteresis regulation onset-critical for precision threshold detection |
| Very low leakage current | <0.1 μA at rated reverse voltage preserves battery life in always-on monitoring systems |
| Optimized thermal resistance | 330 K/W junction-to-solder-point allows reliable operation up to 125 °C board temperature with standard layout |
| E24 voltage coverage | Part of 34-value series spanning 2.4 V–51 V; simplifies BOM consolidation across multiple voltage rails |
Applications
| Power Supply Reference | Overvoltage Clamp |
|---|---|
Use Scenario: Stabilizing feedback node in low-current LDO or op-amp reference circuit. IC Role / Device Role / Timing Role: Provides fixed 10 V reference voltage for error amplifier comparison.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 10 V Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | ±5 % tolerance, 100 Ω rdif, higher leakage (≤5 μA) | Acceptable where cost > precision; unsuitable for <1 μA standby designs | Select for high-volume consumer products where 10.5 V worst-case regulation is acceptable |
| MMSZ5240B | ±5 % tolerance, 17 Ω rdif, 100 pF capacitance, SOD-123 package | Lower impedance improves regulation but larger footprint increases board area | Choose when tighter dynamic regulation outweighs SMT placement density constraints |
Compared with PZU84-B10R, BZX84-C10 trades precision for cost and MMSZ5240B trades compactness for lower impedance-making PZU84-B10R optimal for space-constrained, battery-operated systems requiring ±2 % stability and sub-μA leakage.

FAQ
What is the maximum continuous forward current for PZU84-B10R?
The absolute maximum forward current is 200 mA per limiting values table, but forward conduction is not its intended operating mode. In normal Zener regulation, the device operates in reverse bias; forward voltage is specified only for characterization (0.9 V at 10 mA). Sustained forward current above 100 mA risks thermal runaway due to lack of thermal derating data in that quadrant.
Can PZU84-B10R be used in automotive applications?
No-PZU84-B10R is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed PPAP documentation. Nexperia explicitly states non-automotive qualification in legal disclaimers; use requires full customer qualification including HTOL, ESD, and board-level thermal stress testing.
How does the "B" suffix differ from "C" in PZU84 part numbering?
The "B" suffix denotes ±2 % voltage tolerance and very low leakage current (<0.1 μA), while "C" indicates approximately ±5 % tolerance and higher leakage optimized for fast switching. For PZU84-B10R, this means guaranteed 9.8–10.2 V regulation and suitability for ultra-low-power monitoring versus broader tolerance and faster response in "C" variants.
Is pin 2 truly unconnected, or can it be used for thermal relief?
Pin 2 is internally not connected per official pinning table and graphic symbol; connecting it to ground or thermal copper violates the specified SOT23 outline and risks shorting internal die structures. Thermal management must rely solely on pins 1 (anode) and 3 (cathode), with cathode (pin 3) providing the primary thermal path per Rth(j-sp) = 330 K/W specification.
