Product details
Overview
PZU84-C6V8-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 6.47 V to 7.14 V nominal breakdown at 5 mA, with 60 Ω differential resistance, 3.5 mV/K temperature coefficient, and 215 pF capacitance at 1 MHz - used for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-C6V8-QR datasheet, PZU84-C6V8-QR pinout, PZU84-C6V8-QR application, or PZU84-C6V8-QR equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at low current (IZ = 5 mA), leakage current (≤0.5 μA at VR = 6.8 V), thermal resistance (Rth(j-a) = 500 K/W), and AEC-Q101 qualification status.
Technical Context
This Zener diode operates in reverse-biased breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its hard breakdown knee and very low leakage current (<0.5 μA at VR = 6.8 V) support high-accuracy regulation in low-power sensing circuits.
The device features a 60 Ω typical differential resistance at IZ = 5 mA and a +1.2 mV/K to +4.5 mV/K temperature coefficient across operating current, enabling predictable voltage drift compensation in automotive ambient ranges (−55 °C to +150 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.47 V to 7.14 V at IZ = 5 mA - defines precise clamping threshold for 6.8 V nominal rail protection |
| Differential Resistance (rdif) | 60 Ω typ. at IZ = 5 mA - ensures minimal output voltage shift under load transients |
| Temperature Coefficient (SZ) | +1.2 mV/K to +4.5 mV/K - enables predictable thermal drift modeling in engine control units |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 6.8 V - preserves low quiescent current in always-on automotive modules |
| Capacitance (Cd) | 215 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in ECU signal conditioning paths |
| Power Dissipation (Ptot) | 250 mW at Tamb = 25 °C - supports continuous regulation in compact SOT23 footprint without forced cooling |
| Junction Temperature (Tj) | −55 °C to +150 °C - meets under-hood thermal requirements per AEC-Q101 stress testing |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), qualified per AEC-Q101 for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential side of regulated node |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating - no PCB trace or soldering required |
| 3 | Cathode (K) | Reverse-biased terminal; ties to regulated voltage rail and provides Zener conduction path |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables tight regulation without post-production trimming in ADAS sensor supply rails |
| Very low dynamic impedance (60 Ω) | Maintains <10 mV output variation across 1–10 mA load steps in microcontroller reference circuits |
| Hard breakdown knee | Ensures sharp, repeatable turn-on behavior critical for overvoltage latch detection in battery management systems |
| AEC-Q101 qualification | Validates reliability for 15-year automotive service life under thermal cycling, humidity, and mechanical shock |
| Low leakage (≤0.5 μA) | Minimizes standby current drain in always-on telematics modules powered by 12 V vehicle battery |
Applications
| Automotive Engine Control Unit (ECU) Reference | ADAS Camera Power Rail Protection |

FAQ
What is the maximum non-repetitive peak reverse power dissipation for PZU84-C6V8-QR?
The PZU84-C6V8-QR supports 40 W non-repetitive peak reverse power dissipation at tp = 100 μs (square wave), with junction temperature at 25 °C prior to surge. This rating enables robust transient suppression during ISO 7637-2 load dump events without permanent parameter shift or bond wire failure.
Does PZU84-C6V8-QR have a connected pin 2?
No - pin 2 is explicitly marked "n.c." (not connected) in the official Nexperia pinning diagram and internal die layout. It must remain unconnected on the PCB; routing or soldering to pin 2 violates the device's qualified construction and may compromise AEC-Q101 reliability performance.
How does the temperature coefficient affect regulation accuracy over automotive temperature range?
With a specified SZ of +1.2 mV/K to +4.5 mV/K, the PZU84-C6V8-QR exhibits predictable positive drift: VZ increases ~25 mV from −40 °C to +125 °C ambient. This behavior is fully characterized in the datasheet and enables accurate compensation in closed-loop reference designs using lookup tables or analog correction networks.
Is PZU84-C6V8-QR compatible with lead-free reflow soldering profiles?
Yes - the SOT23 package is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C (10 s max). The recommended footprint matches Nexperia's sot23_fr layout (0.6 mm solder land width, 0.5 mm spacing), ensuring reliable joint formation without tombstoning or voiding.
