Product details
Overview
PZU84-C36-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 36 V nominal breakdown (34.0–38.0 V), 300 Ω differential resistance at 5 mA, and 27 mV/K temperature coefficient; designed for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-C36-QR datasheet, PZU84-C36-QR pinout, PZU84-C36-QR application, or PZU84-C36-QR equivalent, this page delivers verified Zener parameters, AEC-Q101 qualification status, thermal resistance (330 K/W junction-to-solder point), low-leakage operation (<0.05 μA at VR = 30 V), and SOT23 terminal mapping - all critical for automotive ECU and ADAS subsystem design.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with hard knee characteristics, optimized for stable regulation under low-current conditions (IZ = 0.5–5 mA). Its ±2 % tolerance and 300 Ω dynamic impedance at 5 mA support tight voltage reference accuracy in feedback loops.
Designed per AEC-Q101, it sustains 150 °C junction temperature and handles non-repetitive 40 W surge pulses (tp = 100 μs), while exhibiting 0.9 V forward voltage at 10 mA - enabling bidirectional clamping and dual-role use in protection + reference circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 34.0–38.0 V at IZ = 5 mA; enables precise 36 V rail monitoring and clamp threshold setting |
| Differential Resistance rdif | 300 Ω max at IZ = 5 mA; ensures minimal output voltage shift under load current variation |
| Temperature Coefficient SZ | 27 mV/K at IZ = 5 mA; provides predictable drift compensation in wide-temperature automotive environments |
| Reverse Current IR | <0.05 μA at VR = 30 V; guarantees ultra-low standby leakage in always-on vehicle modules |
| Total Power Dissipation Ptot | 250 mW at Tamb = 25 °C on FR4 PCB; defines continuous DC regulation capability without heatsinking |
| Junction-to-Solder-Point Rth(j-sp) | 330 K/W; determines thermal rise above PCB copper during transient surges |
| Non-Repetitive Peak Power PZSM | 40 W at tp = 100 μs; supports robust ESD/ISO 7637-2 pulse suppression |
Pinout & Package
Package: SOT23 plastic surface-mount package (2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch), qualified for reflow and wave soldering per JEDEC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | Anode connection | Forward bias terminal; connects to lower-potential node in Zener shunt configuration |
| 2 (n.c.) | Not connected | Internally unconnected; must remain floating - no PCB trace or thermal pad required |
| 3 (Cathode) | Cathode connection | Reverse-bias terminal; ties to regulated voltage node and serves as primary thermal path to PCB |
Key Features

FAQ
What is the maximum continuous reverse power dissipation for PZU84-C36-QR at 85 °C ambient?
At Tamb = 85 °C, derated power is 150 mW, calculated using the 250 mW rating at 25 °C and thermal resistance of 500 K/W (junction-to-ambient). This assumes standard FR4 PCB mounting with single-sided 70 μm copper and tin plating per datasheet condition [1]. No forced airflow or heatsinking is assumed.
Does PZU84-C36-QR support bidirectional ESD protection?
No - PZU84-C36-QR is a unidirectional Zener diode optimized for reverse-bias regulation. Its forward voltage is 0.9 V at 10 mA, but it lacks symmetric clamping behavior or specified forward surge capability. For bidirectional protection, a dedicated TVS array like PESD5V0S1BA must be used alongside it.
How does the "C" suffix in PZU84-C36-QR affect its electrical behavior versus "B" variants?
The "C" suffix denotes the ±2 % tolerance series with very low dynamic impedance and ultra-low leakage (<0.05 μA), whereas "B" variants have ~±5 % tolerance and intentionally higher leakage for noise reduction in switching applications. PZU84-C36-QR is selected for precision reference roles, not fast-switching contexts.
Can PZU84-C36-QR replace older PZU84-C36 models without layout changes?
Yes - PZU84-C36-QR uses identical SOT23 package dimensions, pinout (anode/cathode/n.c.), and solder footprint per Figures 10 and 11. The "QR" suffix indicates tape-and-reel packaging with updated AEC-Q101 test reporting; no PCB redesign or requalification is needed for drop-in replacement.
