Product details
Overview
PZU84-C7V5-QR from Nexperia is a ±5 % tolerance Zener voltage regulator diode in SOT23 package, rated for 7.5 V nominal breakdown voltage at IZ = 5 mA, with differential resistance of 60 Ω, temperature coefficient of +2.5 mV/K, and reverse leakage ≤0.5 μA at VR = 4 V - used for precision voltage reference and overvoltage clamping in automotive power rails.
For engineers reviewing the PZU84-C7V5-QR datasheet, PZU84-C7V5-QR pinout, PZU84-C7V5-QR application, or PZU84-C7V5-QR equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (Rth(j-a) = 500 K/W), non-repetitive surge capability (40 W @ 100 μs), and SOT23 terminal mapping to support automotive-grade design-in and BOM validation.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with hard knee characteristics optimized for stable regulation at low currents (IZ = 0.5 mA to 5 mA). Its +2.5 mV/K temperature coefficient ensures predictable drift across −55 °C to +150 °C ambient range, supporting automotive under-hood applications.
The device features intentional minor leakage rise (per AN90031) to improve switching speed and reduce noise in transient suppression circuits. It is qualified per AEC-Q101 with Tj max = 150 °C and PZSM = 40 W for short-duration surges, enabling use in ISO 7637-2 compliant load-dump protection stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (nominal) | 7.5 V at IZ = 5 mA - defines regulated output voltage under standard test current |
| Tolerance | ±5 % - specifies allowable deviation from nominal VZ, critical for reference accuracy in feedback loops |
| rdif | 60 Ω at IZ = 5 mA - determines regulation stiffness and output impedance in shunt configuration |
| SZ | +2.5 mV/K - quantifies voltage drift vs. junction temperature, enabling thermal error budgeting |
| IR | ≤0.5 μA at VR = 4 V - confirms low standby power loss in always-on monitoring circuits |
| Ptot | 250 mW at Tamb = 25 °C - sets maximum continuous dissipation on FR4 PCB with standard footprint |
| PZSM | 40 W @ 100 μs square wave - supports transient energy absorption in automotive load-dump events |
Pinout & Package
SOT23 plastic surface-mounted package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pitch); terminals are anode (Pin 1), not connected (Pin 2), cathode (Pin 3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Connected to lower-potential node in reverse-bias configuration; carries forward current during fault conditions |
| 2 | Not connected (n.c.) | Electrically isolated; no internal bond wire; must remain unconnected in PCB layout |
| 3 | Cathode (K) | Connected to regulated voltage node; serves as reference output and surge return path |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive under-hood use with extended temperature range (−55 °C to +150 °C) |
| Hard breakdown knee | Enables sharp, repeatable conduction onset at VZ, improving regulation stability at low IZ |
| Optimized leakage profile | Controlled minor leakage rise improves switching speed and reduces high-frequency noise in clamp circuits |
| Low dynamic impedance | 60 Ω at 5 mA ensures minimal output voltage variation under load transients |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5,115 | ±5 % tolerance, same VZ and SOT23 package, but rdif = 80 Ω (vs. 60 Ω) and Rth(j-a) = 550 K/W (vs. 500 K/W) | Lacks AEC-Q101 qualification; rated only for commercial temperature range (−65 °C to +150 °C storage, but not automotive operation) | Select when cost sensitivity outweighs automotive qualification and tighter regulation stiffness requirements |
| MMSZ5235B-TP | ±5 % tolerance, VZ = 7.5 V, but rdif = 100 Ω and IR = 1 μA at VR = 4 V (vs. 0.5 μA) | Not AEC-Q101 qualified; thermal resistance Rth(j-a) = 625 K/W limits power handling on standard FR4 | Prefer for consumer-grade portable electronics where leakage and thermal margin are less critical |
Compared with BZX84-C7V5,115 and MMSZ5235B-TP, PZU84-C7V5-QR provides superior regulation stiffness (60 Ω), lower leakage, and guaranteed automotive qualification - making it the only choice for safety-critical 12 V rail clamping where long-term reliability under thermal cycling and surge stress is mandatory.

FAQ
What is the maximum non-repetitive surge power rating for PZU84-C7V5-QR?
The device supports 40 W non-repetitive peak reverse power dissipation (PZSM) at pulse duration tp = 100 μs, square-wave waveform, with junction temperature at 25 °C prior to surge - validated per IEC 60134 absolute maximum rating system and documented in Table 5 of the datasheet.
Is PZU84-C7V5-QR suitable for use in automotive under-hood applications?
Yes - it is fully qualified per AEC-Q101 for discrete semiconductors, with operational ambient temperature range of −55 °C to +150 °C and junction temperature limit of 150 °C, meeting requirements for engine control modules, body control units, and ADAS power domains.
How does the "C" suffix in PZU84-C7V5-QR affect its performance versus "B" variants?
The "C" variant (e.g., PZU84-C7V5-QR) offers very low dynamic impedance and leakage current, optimized for precision regulation at low currents; "B" variants have higher leakage intentionally tuned for faster switching and noise reduction, per Application Note AN90031.
What is the thermal resistance from junction to ambient for PZU84-C7V5-QR on standard FR4?
Rth(j-a) is 500 K/W when mounted on FR4 PCB with single-sided 70 μm copper, tin-plated, and standard SOT23 footprint - measured in free air per Table 6, defining safe continuous power derating above 25 °C ambient.
