Product details
Overview
PZU84-C22-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 22 V nominal breakdown voltage (20.88–23.17 V), 100 Ω differential resistance at 5 mA, and 17 mV/K temperature coefficient; designed for precision voltage reference and overvoltage protection in automotive power rails.
For engineers reviewing the PZU84-C22-QR datasheet, PZU84-C22-QR pinout, PZU84-C22-QR application, or PZU84-C22-QR equivalent, this page delivers verified electrical specs, AEC-Q101 qualification status, thermal resistance data (330 K/W junction-to-solder-point), and real-world use cases in ECU power supervision and CAN transceiver biasing.
Technical Context
This Zener diode operates in reverse-biased breakdown mode with hard knee characteristics, optimized for stable regulation at low currents (IZ = 5 mA) and minimal leakage (IR ≤ 25 μA at VR = 17 V). Its differential resistance of 100 Ω ensures tight voltage control under load variation.
Designed per AEC-Q101, it supports junction temperatures up to 150 °C and features intentional low-noise behavior via controlled leakage rise-enabling clean reference generation in analog sensor signal chains and noise-sensitive automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 22 V nominal; min 20.88 V / max 23.17 V at IZ = 5 mA - defines precise clamping threshold for 24 V system overvoltage protection |
| Differential Resistance (rdif) | 100 Ω at IZ = 5 mA - limits output voltage deviation to ±0.5 V under ±50 mA load current change |
| Temperature Coefficient (SZ) | +17 mV/K at IZ = 5 mA - enables predictable drift compensation in wide-temperature-range automotive environments |
| Reverse Current (IR) | ≤25 μA at VR = 17 V - ensures negligible standby power loss in always-on vehicle modules |
| Total Power Dissipation (Ptot) | 250 mW at Tamb = 25 °C on FR4 PCB - supports continuous operation in compact engine control units without heatsinking |
| Junction-to-Solder-Point Rth(j-sp) | 330 K/W - allows accurate thermal modeling when mounted on cathode-tab solder points in high-reliability PCB layouts |
| Non-repetitive Peak Power (PZSM) | 40 W at tp = 100 μs - provides robust transient surge immunity against ISO 7637-2 pulse 1/2a/5a events |
Pinout & Package
SOT23 plastic surface-mount package: 2.9 mm × 1.3 mm × 1.0 mm body, 1.9 mm pin pitch, 3-terminal configuration with exposed cathode tab for thermal conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (A) | Forward-biased terminal; connects to lower-potential node during regulation; carries full forward current in test conditions |
| 2 | Not Connected (n.c.) | Internally unconnected; must remain floating-no PCB trace or thermal pad connection permitted |
| 3 | Cathode (K) | Breakdown terminal; ties to regulated voltage rail; serves as primary thermal path to PCB copper via solder point |
Key Features
| Feature | Design Value |
|---|---|
| ±2 % Zener voltage tolerance | Enables single-supply 22 V reference accuracy without post-production trimming in ADAS domain controllers |
| AEC-Q101 qualification | Validated for automotive under-hood applications including transmission control modules and battery management systems |
| Hard breakdown knee | Ensures rapid transition into regulation at 22 V, minimizing overshoot during load dump transients |
| Low dynamic impedance at 5 mA | Maintains <±25 mV output shift across 1–10 mA operating range-critical for ADC reference stability |
| Optimized leakage for noise reduction | Controlled IR rise improves SNR in analog front-ends for oxygen sensor interfaces and LIN bus receivers |
Applications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C22-TP | ±5 % tolerance; 120 Ω rdif at 5 mA; no AEC-Q101 qualification | Acceptable for non-automotive industrial controls but fails automotive ECU validation | Select only for cost-sensitive consumer electronics where 22 V ±1.1 V tolerance suffices |
| MMSZ5248B-TP | ±5 % tolerance; 300 Ω rdif; 500 mW Ptot; SOD-123 package | Larger footprint and higher impedance limit use in space-constrained CAN nodes | Prefer when higher power handling is needed and board area permits larger package |

FAQ
What is the maximum allowable reverse voltage before breakdown for PZU84-C22-QR?
The device exhibits sharp breakdown at 22 V nominal, with guaranteed conduction starting at 20.88 V (min VZ) under 5 mA test current. It remains in high-impedance state below 17 V (VR = 17 V yields IR ≤ 25 μA), making it unsuitable as a low-voltage clamp but ideal for 22 V threshold detection.
Can PZU84-C22-QR be used in parallel for higher power dissipation?
No-Zener diodes exhibit negative temperature coefficients and mismatched VZ tolerances, causing current hogging and thermal runaway when paralleled. For >250 mW needs, use a single higher-rated device like PZU12-C22-QR or add external current-sharing resistors with ≥5 % VZ matching.
How does the "n.c." pin affect PCB layout and thermal performance?
Pin 2 is internally unconnected and must not be soldered or tied to any net. Routing traces or thermal vias to it degrades SOT23 mechanical integrity and violates Nexperia's mounting guidelines. Thermal path relies solely on pins 1 (anode) and 3 (cathode), with cathode tab providing dominant heat conduction.
Is PZU84-C22-QR compatible with lead-free reflow profiles?
Yes-it is qualified for standard JEDEC J-STD-020D Level 1 reflow (peak 260 °C, 30 sec max), with SOT23 package dimensions and solder land patterns defined in Figures 10–11 of the datasheet. Wave soldering requires orientation per Figure 11's preferred transport direction to avoid tombstoning.
