Product details
Overview
PZU84-B30-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode with nominal 30 V breakdown voltage, 200 mA maximum forward current, and 250 mW total power dissipation in SOT23 package; designed for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-B30-QR datasheet, PZU84-B30-QR pinout, PZU84-B30-QR application, or PZU84-B30-QR equivalent, key selection criteria include Zener voltage tolerance (±2 %), differential resistance (200 Ω at IZ = 5 mA), junction temperature limit (150 °C), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 30 V regulation across load and line variations, with hard breakdown knee and low leakage current optimized for low-noise analog references. Its thermal resistance from junction to ambient is 500 K/W on standard FR4 PCB.
The device exhibits a temperature coefficient of +23 mV/K at IZ = 5 mA and 30 V nominal working voltage, enabling predictable drift compensation in temperature-sensitive circuits; diode capacitance is 66 pF at 1 MHz and 0 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 28.0 V to 32.0 V at IZ = 5 mA - defines precise regulation window for 30 V nominal rail |
| Differential Resistance rdif | 200 Ω max at IZ = 5 mA - determines output impedance and load regulation error |
| Reverse Current IR | 0.05 μA max at VR = 23 V - ensures minimal standby power loss in high-impedance bias networks |
| Forward Voltage VF | 0.9 V max at IF = 10 mA - supports low-loss forward conduction in clamp or dual-direction protection |
| Junction Temperature Tj | −55 °C to +150 °C - enables operation in under-hood automotive environments |
| Non-repetitive Peak Power | 40 W at tp = 100 μs - provides transient surge immunity against ISO 7637-2 pulse 1/2a/5a |
Pinout & Package
Package: SOT23 plastic surface-mounted package; 2.9 mm × 1.3 mm × 1.0 mm body; 1.9 mm lead pitch; three terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connects to lower-potential node in reverse-bias regulation configuration |
| 2 | Not Connected (n.c.) | Internally isolated; must remain unconnected on PCB to avoid parasitic coupling |
| 3 | Cathode (K) | Connects to regulated voltage node; carries full Zener current during breakdown |
Key Features

|---|---|
| ±2 % Zener voltage tolerance | Enables tight regulation without post-production trimming in 12 V–48 V automotive subsystems |
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling |
| Hard breakdown knee | Ensures sharp turn-on and minimal voltage hysteresis in feedback loops and reference buffers |

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-C30 | ±5 % tolerance; 300 Ω typical rdif; no AEC-Q101 qualification | Acceptable for consumer-grade 30 V clamping but not automotive functional safety paths | Select when cost sensitivity outweighs automotive qualification and tighter regulation needs |
| MMSZ5256ET1G | ±5 % tolerance; 1000 mW Ptot; SOD-123 package; higher thermal resistance | Better power handling but larger footprint and looser voltage accuracy | Prefer for high-surge industrial applications where board space permits larger package |
Compared with BZX84-C30 and MMSZ5256ET1G, PZU84-B30-QR delivers superior voltage accuracy (±2 % vs. ±5 %), lower dynamic impedance (200 Ω vs. ≥300 Ω), and automotive qualification-making it optimal for safety-critical 30 V reference and clamp functions where precision and reliability are non-negotiable.

FAQ
What is the Zener voltage tolerance for PZU84-B30-QR?
PZU84-B30-QR has a guaranteed ±2 % Zener voltage tolerance at IZ = 5 mA, meaning its breakdown voltage falls between 28.0 V and 32.0 V under specified test conditions. This tighter tolerance than standard ±5 % Zeners enables higher-accuracy voltage references in automotive and industrial designs without external trimming.
Is PZU84-B30-QR qualified for automotive applications?
Yes-PZU84-B30-QR is fully qualified to AEC-Q101 for discrete semiconductors, having passed stress tests including high-temperature reverse bias, high-temperature operating life, and temperature cycling. It is recommended for use in automotive power management, body electronics, and infotainment systems.
What is the maximum reverse current at 23 V for PZU84-B30-QR?
The maximum reverse current (IR) is 0.05 μA at VR = 23 V and Tj = 25 °C. This ultra-low leakage supports energy-sensitive applications such as always-on battery monitors and low-power sensor nodes where standby current must be minimized.
Can PZU84-B30-QR be used in place of a standard 30 V Zener diode?
Yes, but only if the design requires ±2 % tolerance, AEC-Q101 qualification, and low-leakage performance. Its SOT23 package and pin 2 (n.c.) require layout verification-pin 2 must remain unconnected. Substitution into legacy designs using ±5 % Zeners may improve regulation accuracy but does not change footprint or basic function.
