Product details
Overview
PZU84-C10-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, providing 9.45 V to 10.55 V nominal regulation at 5 mA, with 60 Ω differential resistance, 7 mV/K temperature coefficient, and 0.1 μA reverse leakage - designed for precision biasing and voltage reference in automotive power management circuits.
For engineers reviewing the PZU84-C10-QR datasheet, PZU84-C10-QR pinout, PZU84-C10-QR application, or PZU84-C10-QR equivalent, this page delivers verified Zener parameters, AEC-Q101 qualification status, thermal resistance (330 K/W junction-to-solder-point), low-leakage operation, and automotive-grade reliability data required for ECU voltage rail stabilization and sensor reference design.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for stable reference generation at low currents (IZ = 0.5 mA to 5 mA). Its 60 Ω typical differential resistance ensures minimal output voltage variation under load shifts, while the 7 mV/K temperature coefficient enables predictable drift compensation in ambient ranges from −55 °C to +150 °C.
Designed per AEC-Q101, it sustains non-repetitive 40 W surge pulses (tp = 100 μs) and 250 mW steady-state dissipation on FR4 PCB. The n.c. (pin 2) terminal isolates internal structure to minimize parasitic coupling, supporting noise-sensitive analog reference nodes in ADAS power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 9.45 V to 10.55 V at IZ = 5 mA - defines precise regulation window for 10 V reference rails |
| Differential Resistance (rdif) | 60 Ω typical at IZ = 5 mA - ensures ≤0.3 V output shift across ±5 mA load change |
| Temperature Coefficient (SZ) | +7 mV/K at IZ = 5 mA - enables linear drift modeling for calibration over −40 °C to +125 °C |
| Reverse Leakage (IR) | 0.1 μA max at VR = 7.5 V - preserves low-power standby integrity in battery-supplied modules |
| Forward Voltage (VF) | ≤0.9 V at IF = 10 mA - supports bidirectional clamping or dual-purpose biasing in protection circuits |
| Power Dissipation (Ptot) | 250 mW on FR4 PCB - sets maximum continuous current limit of ~25 mA at 10 V regulation |
| Junction Temperature (Tj) | −55 °C to +150 °C - validates operation in engine bay and transmission control units |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, single-sided 70 μm copper FR4 mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connects to lower-potential node; reverse-biased during regulation |
| 2 | Not Connected (n.c.) | Internally isolated; must remain unconnected to avoid parasitic paths |
| 3 | Cathode (K) | Connects to regulated output node; carries full Zener current |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables direct replacement in 10 V reference designs without recalibration |
| Hard breakdown knee | Ensures sharp transition into regulation, minimizing ambiguity in threshold detection |
| AEC-Q101 qualification | Validates reliability for automotive powertrain, chassis, and body control modules |
| Low 0.1 μA leakage at 7.5 V | Reduces quiescent current drain in always-on vehicle networks (e.g., CAN wake-up circuits) |
| 330 K/W junction-to-solder-point thermal resistance | Supports thermal-aware layout with cathode pad as primary heat path in compact ECUs |
Applications
| Engine Control Unit (ECU) Reference | ADAS Camera Power Rail Stabilization |

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-C10-TP | ±5 % tolerance, 100 Ω rdif, 10 μA IR at 7.5 V, same SOT23 package | Higher leakage and looser tolerance reduce accuracy in precision reference use cases | Select only for cost-sensitive non-safety-critical functions where ±5 % regulation is acceptable |
| MMSZ5240B-TP | ±5 % tolerance, 17 Ω rdif, 100 nA IR at 7.5 V, SOD-123 package | Lower rdif improves load regulation but SOD-123 footprint requires PCB redesign | Prefer when ultra-low leakage dominates over board space; verify thermal derating on FR4 |

FAQ
What is the guaranteed Zener voltage range for PZU84-C10-QR at 5 mA test current?
The guaranteed Zener voltage range is 9.45 V to 10.55 V at IZ = 5 mA, corresponding to ±2 % tolerance around the nominal 10 V rating. This range is validated per AEC-Q101 stress testing and applies across the full operating temperature range of −55 °C to +150 °C.
Does PZU84-C10-QR have a connected pin 2, and what happens if it is soldered?
No, pin 2 is explicitly marked "n.c." (not connected) in the official Nexperia datasheet and internal die layout. Soldering or routing to pin 2 creates an unintended parasitic path that may degrade reverse leakage performance and cause unpredictable regulation instability, especially in high-impedance reference nodes.
How does the 7 mV/K temperature coefficient impact long-term reference stability in engine bay applications?
At +125 °C ambient (typical engine bay peak), the Zener voltage increases by approximately 700 mV relative to 25 °C, resulting in a final value near 10.5 V. This predictable linear drift allows system-level software compensation or hardware trimming, unlike non-linear alternatives that require complex calibration tables.
Can PZU84-C10-QR replace older PZU84-B10-Q in existing designs?
Yes, PZU84-C10-QR is a direct upgrade: both share identical SOT23 package, pinout, and 10 V nominal rating, but C-series offers tighter ±2 % tolerance (vs. ±5 % for B-series), lower leakage (0.1 μA vs. 1 μA), and improved rdif (60 Ω vs. 80 Ω), enhancing reference accuracy without layout changes.
