Product details
Overview
PZU84-C8V2-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 8.2 V nominal breakdown voltage at IZ = 5 mA, with differential resistance of 60 Ω, reverse leakage ≤0.5 μA at VR = 5 V, and qualified to AEC-Q101 for automotive power rail stabilization.
For engineers reviewing the PZU84-C8V2-QR datasheet, PZU84-C8V2-QR pinout, PZU84-C8V2-QR application, or PZU84-C8V2-QR equivalent, this part supports precision voltage reference, overvoltage clamping, and ESD-robust biasing in engine control units, ADAS sensor interfaces, and infotainment power domains where low dynamic impedance and hard breakdown knee are critical.
Technical Context
This Zener diode operates in reverse breakdown mode with a sharp, hard knee characteristic optimized for stable regulation at low currents (IZ = 0.5–5 mA). Its differential resistance of 60 Ω at IZ = 5 mA ensures minimal output voltage variation under load transients.
Designed per AEC-Q101, it delivers junction temperature operation up to 150 °C and features intentional low leakage (≤0.5 μA at VR = 5 V) and temperature coefficient of +3.2 mV/K - enabling predictable drift compensation in automotive ambient ranges.
Key Specifications

| Nominal Zener Voltage | 8.2 V at IZ = 5 mA - defines precise regulation point for 8 V-class power rails |
| Tolerance | ±2 % - enables tight voltage margin control in safety-critical automotive circuits |
| Differential Resistance | 60 Ω at IZ = 5 mA - ensures <10 mV output shift per 0.17 mA load change |
| Reverse Leakage Current | ≤0.5 μA at VR = 5 V - minimizes standby power loss in always-on modules |
| Power Dissipation | 250 mW at Tamb = 25 °C - supports continuous regulation in compact SOT23 footprint |
| Junction Temperature Range | −55 °C to +150 °C - meets under-hood thermal requirements without derating |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including HTOL, TC, and ESD HBM ≥2 kV |
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 reflow and wave soldering per IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Connected to lower-potential node; reverse-biased during regulation |
| 2 (n.c.) | Not connected | Internally unconnected terminal; must remain floating per design |
| 3 (Cathode) | Cathode connection | Connected to higher-potential node; carries regulated current path |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables stable regulation at low currents (0.5–5 mA) without soft turn-on ambiguity |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C8V2,115 | ±5 % tolerance, 80 Ω rdif at 5 mA, no AEC-Q101 qualification | Acceptable for consumer-grade power supervision but not automotive safety-critical functions | Select when cost sensitivity outweighs automotive qualification and tighter regulation |
| MMSZ5236B-TP | ±5 % tolerance, 30 Ω rdif at 20 mA, 500 mW Ptot, no AEC-Q101 | Better dynamic impedance at high current but higher leakage (1 μA) and unqualified for automotive | Prefer for industrial SMPS feedback where higher power and looser tolerance are acceptable |

FAQ
What is the maximum reverse current at 5 V before breakdown for PZU84-C8V2-QR?
The reverse leakage current is guaranteed ≤0.5 μA at VR = 5 V and Tj = 25 °C, per Table 8 of the datasheet. This value remains below 1 μA across the full −55 °C to +150 °C junction temperature range, ensuring minimal standby power impact in always-on vehicle networks.
Can PZU84-C8V2-QR replace BZX84-C8V2 in an existing automotive design?
Yes, but only after validation: PZU84-C8V2-QR offers tighter ±2 % tolerance, lower 60 Ω dynamic resistance, and AEC-Q101 qualification versus BZX84-C8V2's ±5 % and no automotive qualification. Layout and thermal design remain identical due to shared SOT23 package and pinout.
What is the non-repetitive peak reverse power rating and test condition?
PZU84-C8V2-QR supports 40 W non-repetitive peak reverse power dissipation (PZSM) for pulse duration tp = 100 μs, square-wave waveform, with junction temperature at 25 °C prior to surge - per Table 5 limiting values and Figure 1 characterization.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With a specified temperature coefficient of +3.2 mV/K, the Zener voltage shifts +32 mV from −40 °C to +125 °C (ΔT = 165 K), resulting in ~0.39 % drift relative to 8.2 V nominal. This is fully characterized and compensated in AEC-Q101-compliant designs using standard thermal modeling.
