Product details
Overview
PZU84-B8V2-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, junction temperature up to 150 °C, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the PZU84-B8V2-QR datasheet, PZU84-B8V2-QR pinout, PZU84-B8V2-QR application, or PZU84-B8V2-QR equivalent, this page delivers verified Zener parameters including VZ, rdif, IR, thermal resistance, and automotive-grade reliability data required for precision voltage reference and overvoltage protection design.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable 8.2 V regulation across load and line variations, with hard breakdown knee and low leakage current optimized for low-noise analog references and ECU supply monitoring. Its 60 Ω differential resistance ensures tight regulation under dynamic current shifts.
Designed per AEC-Q101, it supports automotive ambient temperatures from −55 °C to +150 °C and withstands non-repetitive 40 W surge pulses (tp = 100 μs), making it suitable for transient suppression in 12 V battery systems and CAN node voltage clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 8.2 V at IZ = 5 mA - precise reference voltage for feedback loops and voltage supervision |
| Tolerance | ±2 % - enables high-accuracy regulation without post-production trimming |
| rdif | 60 Ω max at IZ = 5 mA - low impedance ensures minimal output voltage deviation under load transients |
| IR | 0.5 μA max at VR = 6.6 V - ultra-low leakage preserves battery life in always-on automotive modules |
| Ptot | 250 mW - sufficient for biasing and low-power reference applications on FR4 PCBs |
| Rth(j-a) | 500 K/W - defines thermal derating curve for ambient temperature operation up to 150 °C |
| AEC-Q101 | Qualified - validated for automotive under-hood and infotainment system deployment |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch) with three terminals; terminal 2 is internally not connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased connection point; reverse-biased during Zener operation |
| 2 | Not connected (n.c.) | No internal bond wire; must remain unconnected in PCB layout |
| 3 | Cathode (K) | Reference node for regulated voltage; connects to circuit ground or return path |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables sharp, predictable turn-on at 8.2 V for reliable overvoltage detection in safety-critical ECUs |
| Low dynamic impedance | 60 Ω ensures <10 mV output shift per 1 mA load change - critical for ADC reference stability |
| Ultra-low leakage | ≤0.5 μA at 80 % of VZ minimizes standby current in always-on vehicle networks |
| AEC-Q101 qualification | Validated for 1000-hour high-temperature operating life and mechanical shock - meets automotive Tier-1 requirements |

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-C8V2 | ±5 % tolerance, higher rdif (100 Ω), no AEC-Q101 qualification | Acceptable for consumer-grade power supplies but unsuitable for automotive functional safety paths | Select only for cost-sensitive non-automotive designs where ±5 % regulation is acceptable |
| MMSZ5236B | ±5 % tolerance, 8.2 V nominal, 100 Ω rdif, 200 mW Ptot, no AEC-Q101 | Limited surge capability (25 W vs. 40 W); higher thermal resistance (550 K/W) | Use only in industrial controls with controlled ambient and no transient stress requirements |
Compared with BZX84-C8V2 and MMSZ5236B, PZU84-B8V2-QR delivers tighter ±2 % tolerance, lower 60 Ω dynamic impedance, AEC-Q101 validation, and superior 40 W surge rating - making it the sole choice for automotive voltage reference and protection where accuracy, reliability, and transient immunity are mandatory.

FAQ
What is the maximum reverse current (IR) specification for PZU84-B8V2-QR at 6.6 V?
The maximum reverse leakage current is 0.5 μA at VR = 6.6 V (80 % of nominal VZ), measured at Tj = 25 °C. This ultra-low value ensures minimal power loss in always-on automotive circuits and supports extended battery life in telematics modules.
Does PZU84-B8V2-QR support reflow soldering, and what footprint is recommended?
Yes, it is qualified for lead-free reflow soldering using the standard SOT23 footprint per Figure 10: 0.6 mm solder land width (3×), 0.7 mm solder paste stencil opening (3×), with 1.9 mm pin pitch. Thermal pad is not present; mounting follows JEDEC MS-012 guidelines.
How does the temperature coefficient (SZ) behave for PZU84-B8V2-QR across its operating range?
At VZ = 8.2 V, the temperature coefficient is +3.2 mV/K (typical) over 25–150 °C, indicating positive drift. This value is confirmed in Table 8 for the "B" series and enables predictable compensation in temperature-sensitive reference designs.
Can PZU84-B8V2-QR be used as a substitute for PZU84-C8V2 in an existing design?
No - PZU84-B8V2-QR (±2 %, low-leakage, hard-knee) and PZU84-C8V2 (±5 %, higher leakage, optimized for switching noise reduction) serve distinct design roles. Substitution requires verification of tolerance, leakage, and dynamic impedance impact on regulation accuracy and system noise floor.
