Product details
Overview
PZU84-C6V2-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, with nominal breakdown voltage 6.2 V, differential resistance 80 Ω at 5 mA, and temperature coefficient +0.4 mV/K - designed for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-C6V2-QR datasheet, PZU84-C6V2-QR pinout, PZU84-C6V2-QR application, or PZU84-C6V2-QR equivalent, key selection criteria include Zener voltage tolerance, dynamic impedance at low bias current, leakage current under reverse bias, thermal resistance to solder point, and AEC-Q101 qualification status.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics, optimized for stable regulation at 5 mA test current. Its low 80 Ω differential resistance ensures minimal voltage deviation under load variation, while the +0.4 mV/K temperature coefficient enables predictable drift compensation in 5–12 V range designs.
The device features intentional low leakage (≤0.5 μA at VR = 6.2 V), n.c. terminal isolation, and junction-to-solder-point thermal resistance of 330 K/W - enabling reliable operation up to 150 °C junction temperature in compact automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.86 V to 6.53 V at IZ = 5 mA - defines precise clamping threshold for 6.2 V nominal rail protection |
| Differential Resistance (rdif) | 80 Ω max at IZ = 5 mA - ensures ≤0.4 V output shift across ±4 mA load change |
| Temperature Coefficient (SZ) | +0.4 mV/K - enables predictable +2.4 mV/°C drift over 0–60 °C ambient range |
| Reverse Leakage (IR) | ≤0.5 μA at VR = 6.2 V - minimizes standby power loss in always-on circuits |
| Total Power Dissipation (Ptot) | 250 mW at Tamb = 25 °C on FR4 - supports continuous regulation in space-constrained SMT layouts |
| Junction Temperature (Tj) | −55 °C to +150 °C - validated for under-hood automotive environments per AEC-Q101 |
| Package | SOT23 - 2.9 mm × 1.3 mm × 1.0 mm footprint with 1.9 mm pin pitch for high-density routing |
Pinout & Package
SOT23 plastic surface-mounted package with 3 terminals, 1.9 mm pitch, and standard FR4-compatible footprint (2.9 mm × 1.3 mm × 1.0 mm body). Cathode tab provides lowest thermal resistance path to PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased connection point; tied to lower-potential node during regulation |
| 2 | Not Connected (n.c.) | Internally isolated; must remain unconnected to avoid parasitic coupling or thermal derating |
| 3 | Cathode (K) | Regulated output node; primary heat path to PCB via soldered tab (Rth(j-sp) = 330 K/W) |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 6.2 V reference designs without recalibration or resistor trimming |
| Hard breakdown knee | Ensures sharp transition into regulation with <100 mV overshoot at 1 mA → 10 mA current step |
| AEC-Q101 qualified | Validated for automotive power management including engine control units and ADAS sensor supplies |
| Low 0.5 μA leakage at 6.2 V | Reduces quiescent current in battery-backed systems by >95 % versus ±5 % series variants |
| 330 K/W junction-to-solder-point Rth | Allows 150 °C operation with ≤10 °C rise above board temperature at 200 mW dissipation |

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, no AEC-Q101 qualification | Acceptable for consumer-grade 6.2 V references but not automotive safety-critical rails | Select only for cost-sensitive non-automotive designs where ±5 % tolerance is acceptable |
| MMSZ4687 | ±5 % tolerance, 120 Ω rdif, 350 mW Ptot, SOD-123 package | Larger footprint and higher thermal resistance limit use in dense automotive modules | Prefer only when higher power margin (350 mW) outweighs SOT23 size and AEC-Q101 compliance needs |
Compared with BZX84-C6V2 and MMSZ4687, PZU84-C6V2-QR delivers tighter voltage control, lower dynamic impedance, and automotive-grade reliability in the smallest footprint - making it the sole choice for AEC-Q101-compliant 6.2 V regulation where space and precision are constrained.

FAQ
What is the maximum reverse current before breakdown for PZU84-C6V2-QR?
At 6.2 V reverse bias (VR = 6.2 V), the maximum specified reverse leakage current is 0.5 μA. This value is measured under steady-state DC conditions at Tj = 25 °C and confirms the device remains fully blocking below its 5.86 V minimum Zener voltage threshold.
Can PZU84-C6V2-QR be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficients and mismatched breakdown voltages, causing current hogging when paralleled. The datasheet specifies single-device operation only; for higher power, use a discrete transistor-Zener combination or dedicated TVS array.
Is the n.c. pin electrically isolated or internally bonded?
Pin 2 is confirmed as "not connected" - physically isolated from all internal die structures. It must remain unconnected on PCB; soldering or routing to this pin introduces risk of mechanical stress fracture or unintended capacitance coupling per Nexperia's SOT23 mechanical drawings.
How does the +0.4 mV/K temperature coefficient affect long-term stability?
The +0.4 mV/K coefficient causes a +2.4 mV increase in VZ over a 60 °C rise (e.g., 25 °C to 85 °C ambient). This predictable linear drift allows system-level compensation in closed-loop regulators but requires margining in open-loop reference designs.
