Product details
Overview
PZU84-C5V6-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 5.6 V nominal breakdown at 5 mA, with 100 Ω differential resistance, 2.5 mV/K temperature coefficient, and 275 pF capacitance at 1 MHz - used for precision voltage reference and overvoltage clamping in automotive power rails.
For engineers reviewing the PZU84-C5V6-QR datasheet, PZU84-C5V6-QR pinout, PZU84-C5V6-QR application, or PZU84-C5V6-QR equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data (330 K/W junction-to-solder-point), and automotive-grade leakage current behavior per AN90031.
Technical Context
This Zener diode belongs to the PZU84-C sub-series optimized for low-current regulation with hard breakdown knee, very low leakage (<1 μA at VR = 5 V), and stable dynamic impedance down to 100 Ω at IZ = 5 mA. It operates within −55 °C to +150 °C ambient range and supports non-repetitive 40 W surge pulses (tp = 100 μs).
Designed per AEC-Q101 for automotive use, it features intentional low leakage for high-impedance biasing and noise-sensitive analog circuits, unlike the B-series variants which trade leakage for faster switching. Its 5.6 V nominal Zener voltage targets mid-range logic supply stabilization and ECU reference generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener voltage VZ | 5.31 V to 5.92 V at IZ = 5 mA - defines tight ±2 % regulation window for stable reference generation |
| Differential resistance rdif | 100 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load variation |
| Temperature coefficient SZ | −2.0 mV/K to +2.5 mV/K - enables predictable drift compensation in wide-temperature environments |
| Reverse current IR | ≤1 μA at VR = 5 V - guarantees low quiescent power loss in always-on monitoring circuits |
| Diode capacitance Cd | 275 pF at f = 1 MHz, VR = 0 V - limits high-frequency noise coupling in signal-path protection |
| Total power dissipation Ptot | 250 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous DC power handling capability |
| Non-repetitive peak power PZSM | 40 W for tp = 100 μs - supports transient overvoltage suppression without failure |
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 reliability.
| 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 solder mask required |
| 3 | Cathode (K) | Zener breakdown terminal; ties to regulated voltage rail and provides reference ground return path |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in precision 5.6 V reference designs without recalibration |
| Hard breakdown knee | Ensures sharp, repeatable conduction onset - critical for accurate overvoltage detection thresholds |
| AEC-Q101 qualification | Validated for automotive powertrain and body electronics with full stress-test compliance |
| Low leakage current | ≤1 μA at 5 V reverse bias - preserves battery life in always-on vehicle modules |
| Optimized thermal resistance | Rth(j-sp) = 330 K/W - allows efficient heat transfer from junction to cathode solder point |
Applications

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-C5V6,115 | ±5 % tolerance, 150 Ω rdif at 5 mA, higher leakage (≤5 μA at 5 V) | Acceptable for non-critical biasing where cost is prioritized over precision | Select when ±5 % regulation and higher leakage are acceptable for cost-sensitive consumer designs |
| MMSZ5232B-TP | ±5 % tolerance, 170 Ω rdif, 100 °C max Tj (vs. 150 °C), no AEC-Q101 qualification | Limited to industrial/commercial use; unsuitable for automotive under-hood deployment | Choose only for non-automotive applications requiring identical footprint but lower qualification rigor |
Compared with BZX84-C5V6 and MMSZ5232B, PZU84-C5V6-QR delivers tighter ±2 % tolerance, lower 100 Ω dynamic impedance, certified AEC-Q101 reliability, and extended 150 °C junction operation - making it the sole choice for automotive-grade 5.6 V reference stability.

FAQ
What is the maximum continuous reverse current the PZU84-C5V6-QR can sustain without degradation?
The device supports up to 200 mA forward current per absolute maximum ratings, but for Zener operation, sustained reverse current is limited by power dissipation: at 25 °C ambient on standard FR4, 250 mW rating permits ~44.6 mA at 5.6 V (P = V × I). Derating applies above 25 °C using Rth(j-a) = 500 K/W.
Does the 'QR' suffix indicate tape-and-reel packaging or a specific automotive grade?
The 'QR' suffix denotes Nexperia's automotive-grade ordering variant: AEC-Q101 qualified, packaged in 3 k-unit tape-and-reel (EIA-481 compliant), with full traceability and extended temperature screening. It is not a separate package type - physical form remains SOT23.
Can PZU84-C5V6-QR replace PZU84-B5V6-Q in an existing design?
No - PZU84-B5V6-Q has higher leakage (~5 μA at 5 V) optimized for fast switching and noise reduction, while PZU84-C5V6-QR uses ultra-low leakage (<1 μA) and hard-knee breakdown for precision regulation. Substitution requires validation of leakage sensitivity and dynamic impedance impact on circuit stability.
Is the n.c. pin (pin 2) electrically isolated or internally bonded to substrate?
Pin 2 is fully unconnected - no internal bond wire or die attachment. It is electrically isolated and may be left unpopulated or grounded on PCB for mechanical stability, but grounding does not affect electrical performance or thermal behavior per Nexperia's SOT23 layout documentation.
