Product details
Overview
PZU84-B6V2-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 6.2 V nominal breakdown at 5 mA, with 80 Ω differential resistance, 3.0 mV/K temperature coefficient, and 250 mW power dissipation - used for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-B6V2-QR datasheet, PZU84-B6V2-QR pinout, PZU84-B6V2-QR application, or PZU84-B6V2-QR equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at low bias current, thermal resistance (330 K/W junction-to-solder-point), AEC-Q101 qualification, and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable regulation at 5 mA test current. Its 6.2 V nominal Zener voltage falls within the B-series subgroup (PZU84-B5V1-Q to -C10-Q), featuring very low leakage (<0.5 μA at VR = 3.0 V) and low dynamic impedance (80 Ω typ. at IZ = 5 mA).
The device uses silicon planar technology with an anode-cathode–not-connected (n.c.) three-terminal configuration in SOT23. It achieves AEC-Q101 qualification via stress testing including Tj up to 150 °C, storage temperature from −65 °C to +150 °C, and non-repetitive 40 W surge capability (tp = 100 μs).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.2 V nominal at IZ = 5 mA; ±2 % tolerance ensures tight regulation in feedback loops |
| Differential Resistance rdif | 80 Ω typical at IZ = 5 mA; enables low output impedance for stable reference under load variation |
| Temperature Coefficient SZ | +3.0 mV/K at IZ = 5 mA; supports predictable drift compensation in automotive ambient ranges |
| Reverse Leakage IR | <0.5 μA at VR = 3.0 V; minimizes standby current in always-on vehicle subsystems |
| Total Power Dissipation Ptot | 250 mW at Tamb = 25 °C on FR4 PCB; defines maximum continuous DC power handling |
| Junction-to-Solder-Point Rth(j-sp) | 330 K/W; determines thermal rise above solder point during pulsed operation |
| Non-repetitive Peak Power PZSM | 40 W for tp = 100 μs square wave; supports transient overvoltage clamping without failure |
Pinout & Package
SOT23 plastic surface-mounted package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal layout with standard footprint per Figure 10 (reflow) and Figure 11 (wave).
| 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 thermal pad connection |
| 3 | Cathode (K) | High-impedance reverse-bias terminal; ties to regulated voltage rail and provides thermal path to PCB copper |
Key Features
| Feature | Design Value |
|---|---|
| Hard breakdown knee | Enables sharp, repeatable turn-on at 6.2 V for accurate threshold detection in protection circuits |
| AEC-Q101 qualified | Validated for automotive under-hood and infotainment applications per discrete semiconductor stress test standard |

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-C6V2 | ±5 % tolerance, 100 Ω rdif at 5 mA, not AEC-Q101 qualified | Acceptable for non-automotive consumer power supplies where cost > precision | Select only if AEC-Q101 compliance and <1 % total error budget are not required |
| MMSZ5234B | ±5 % tolerance, 130 Ω rdif, 500 mW Ptot, SOD-123 package | Higher power handling but larger footprint; lacks automotive qualification | Choose when thermal margin > 250 mW is needed and board space allows SOD-123 |
Compared with BZX84-C6V2 and MMSZ5234B, PZU84-B6V2-QR delivers tighter voltage control (±2 % vs. ±5 %), lower impedance (80 Ω vs. ≥100 Ω), and guaranteed automotive reliability - making it the sole choice for safety-critical 6.2 V references in AEC-Q101–mandated systems.

FAQ
What is the maximum reverse voltage this Zener can regulate continuously?
The PZU84-B6V2-QR is rated for continuous Zener operation at its nominal 6.2 V breakdown voltage with ≤250 mW power dissipation on standard FR4 PCB. At 25 °C ambient, this corresponds to ≤40.3 mA DC reverse current (IZ = Ptot/VZ). Derating is required above 25 °C using Rth(j-a) = 500 K/W.
Does Pin 2 require grounding or thermal connection?
No - Pin 2 is explicitly marked "n.c." (not connected) in the official Nexperia datasheet and must remain electrically and thermally floating. Connecting it risks internal shorting or thermal imbalance; the cathode (Pin 3) serves as the sole thermal conduction path to the PCB.
How does its temperature coefficient affect regulation accuracy over automotive temperature range?
With +3.0 mV/K SZ at 5 mA, the Zener voltage shifts +150 mV from −40 °C to +125 °C (ΔT = 165 K), resulting in ~2.4 % total drift relative to 6.2 V nominal. This is acceptable for non-critical biasing but requires calibration in high-precision ADC references.
Can this device replace older PZU84-B6V2 variants without layout changes?
Yes - PZU84-B6V2-QR shares identical SOT23 mechanical dimensions, pinout, thermal footprint, and electrical specifications with prior PZU84-B6V2 revisions. The "-QR" suffix denotes tape-and-reel packaging with updated AEC-Q101 test documentation; no PCB redesign is needed.
