Product details
Overview
PZU84-B5V6-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 protection in automotive power rails.
For engineers reviewing the PZU84-B5V6-QR datasheet, PZU84-B5V6-QR pinout, PZU84-B5V6-QR application, or PZU84-B5V6-QR equivalent, this page delivers verified Zener parameters, AEC-Q101 qualification status, thermal resistance (330 K/W junction-to-solder-point), leakage current (≤1 μA at VR = 5.6 V), and exact SOT23 terminal mapping to support automotive-grade design validation.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with hard knee characteristics, optimized for stable regulation under low-current conditions (IZ = 0.5 mA to 5 mA). Its ±2 % tolerance and 100 Ω dynamic impedance at 5 mA ensure tight voltage control in feedback loops and reference circuits.
Designed per AEC-Q101, it supports junction temperatures up to 150 °C and ambient ranges from −55 °C to +150 °C. The intentional low leakage (<1 μA) and 275 pF capacitance enable use in noise-sensitive analog monitoring and ECU power supervision without signal coupling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.31 V to 5.92 V at IZ = 5 mA - defines precise clamping threshold for 5.6 V nominal rail protection |
| Differential Resistance (rdif) | 100 Ω max at IZ = 5 mA - ensures minimal output voltage shift under load transients |
| Temperature Coefficient (SZ) | −2.0 mV/K to +2.5 mV/K - enables predictable drift compensation in wide-temperature automotive environments |
| Reverse Leakage (IR) | ≤1 μA at VR = 5.6 V - minimizes standby power loss in always-on vehicle modules |
| Capacitance (Cd) | 275 pF at f = 1 MHz, VR = 0 V - limits high-frequency coupling into adjacent analog signal paths |
| Total Power Dissipation (Ptot) | 250 mW at Tamb = 25 °C on FR4 PCB - sets maximum continuous regulation capability in compact layouts |
| Junction-to-Solder-Point Rth | 330 K/W - informs thermal design margin when mounted on cathode tab of automotive PCBs |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal configuration with anode (Pin 1), not-connected (Pin 2), and cathode (Pin 3).
| 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 solder mask relief required |
| 3 | Cathode (K) | Reverse-bias input; ties to higher-potential rail and serves as primary thermal path to PCB |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 5.6 V reference designs without recalibration or resistor trimming |
| Hard breakdown knee | Ensures sharp, repeatable conduction onset - critical for accurate overvoltage detection in ADAS power domains |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications including engine control units and body controllers |
| Low 100 Ω dynamic impedance | Maintains <±10 mV regulation error across 1–10 mA load variations in sensor biasing circuits |
| 275 pF junction capacitance | Permits use in 1 MHz–10 MHz feedback networks without phase margin degradation in DC-DC controllers |
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 | ±5 % tolerance, 150 Ω rdif, 300 pF Cd, no AEC-Q101 qualification | General-purpose industrial use only; unsuitable for automotive safety-critical functions | Select only for cost-sensitive non-automotive designs where ±5 % tolerance and absence of automotive qualification are acceptable |
| MMSZ5232B | ±5 % tolerance, 17 Ω rdif at 20 mA, 100 pF Cd, AEC-Q101 qualified but SOD-123 package | Higher current capability (20 mA test), smaller capacitance, but larger footprint and different thermal path | Prefer for higher-current regulation (>10 mA) or tighter capacitance requirements, accepting larger SOD-123 board area and rework complexity |
Compared with BZX84-C5V6 and MMSZ5232B, PZU84-B5V6-QR uniquely combines ±2 % tolerance, AEC-Q101 qualification, SOT23 size, and 100 Ω impedance - making it optimal for space-constrained automotive voltage references demanding precision and reliability.

FAQ
What is the maximum reverse current specification for PZU84-B5V6-QR at its rated Zener voltage?
The maximum reverse leakage current is 1 μA at VR = 5.6 V and Tj = 25 °C, as specified in Table 8 of the datasheet. This value increases slightly with junction temperature but remains ≤5 μA up to 125 °C, supporting low-power wake-up and always-on circuit design.
Does PZU84-B5V6-QR support wave soldering, and what is the recommended footprint?
Yes - Nexperia provides dedicated wave soldering footprints (Fig. 11) with 1.4 mm × 2.2 mm solder lands and 2.6 mm transport direction clearance. The SOT23 outline complies with IPC-7351B standard, and the device is qualified for both reflow and wave processes per J-STD-020 and J-STD-002.
How does the temperature coefficient affect regulation accuracy over automotive temperature ranges?
With SZ ranging from −2.0 to +2.5 mV/K, the worst-case drift over −40 °C to +125 °C is ±413 mV (165 K × 2.5 mV/K), resulting in a total VZ span of 5.31 V to 5.92 V. Combined with ±2 % initial tolerance, full-temperature accuracy remains within ±4.5 % of nominal 5.6 V.
Is Pin 2 truly unconnected, and can it be grounded or left floating on PCB layout?
Yes - Pin 2 is internally not connected (n.c.), confirmed in Table 2 and Fig. 9. It must remain electrically floating: grounding or routing traces to it risks mechanical stress or solder bridging. Standard SOT23 land pattern (Fig. 10) omits solder paste on Pin 2, and no copper should be placed beneath it.
