Product details
Overview
PZU84-C15-QR from Nexperia is a ±2 % tolerance Zener voltage regulator diode in SOT23 package, rated for 15 V nominal breakdown voltage at IZ = 5 mA, with differential resistance of 80 Ω (max), junction temperature up to 150 °C, and AEC-Q101 qualification for automotive power rail stabilization.
For engineers reviewing the PZU84-C15-QR datasheet, PZU84-C15-QR pinout, PZU84-C15-QR application, or PZU84-C15-QR equivalent, this part supports precision voltage reference, overvoltage clamping, and low-power supply regulation in space-constrained automotive ECUs and industrial sensor interfaces where stable 15 V Zener behavior and low leakage (<0.05 μA at VR = 11 V) are required.
Technical Context
This Zener diode operates in reverse breakdown mode with hard knee characteristics optimized for low-current regulation (IZ = 0.5 mA to 5 mA), delivering stable 15 V reference with temperature coefficient of +9.2 mV/K (typical at IZ = 5 mA) and diode capacitance of 99 pF at VR = 0 V, f = 1 MHz.
Its thermal resistance from junction to ambient is 500 K/W (free air), and it sustains non-repetitive peak reverse power of 40 W for 100 μs pulses, enabling transient surge suppression in 12 V/24 V automotive subsystems without external buffering.
Key Specifications

| Zener Voltage VZ | 15 V nominal at IZ = 5 mA; ±2 % tolerance ensures tight 14.7–15.3 V regulation window for reference stability |
| Differential Resistance rdif | 80 Ω max at IZ = 5 mA; low impedance maintains voltage accuracy under load current variation |
| Reverse Current IR | 0.05 μA max at VR = 11 V; ultra-low leakage preserves battery life in always-on automotive modules |
| Total Power Dissipation Ptot | 250 mW at Tamb = 25 °C on FR4 PCB; defines continuous DC regulation capability without heatsinking |
| Junction Temperature Tj | −55 °C to +150 °C operating range; enables deployment in engine bay and transmission control units |
| AEC-Q101 Qualified | Stress-tested per automotive discrete semiconductor standard; validates reliability for safety-critical vehicle systems |

FAQ
What is the maximum reverse voltage before breakdown for PZU84-C15-QR?
The nominal Zener voltage is 15 V at IZ = 5 mA, with guaranteed minimum and maximum values of 14.7 V and 15.3 V respectively due to its ±2 % tolerance. Breakdown occurs sharply within this band; operation below 14.7 V yields negligible reverse current (<0.05 μA at 11 V), confirming hard-knee behavior per datasheet Figure 7.
Can PZU84-C15-QR be used in forward-bias applications?
No-it is designed exclusively for reverse-bias Zener operation. Forward voltage is specified only as VF ≤ 0.9 V at IF = 10 mA (pulse test), with no characterization for sustained forward conduction, thermal derating, or switching speed. Using it as a rectifier violates its qualification and may cause premature failure.
How does the "C" suffix in PZU84-C15-QR affect its electrical behavior?
The "C" denotes the ±2 % tolerance series (vs "B" for ~±5 %), and selects the low-leakage variant optimized for general regulation. Per datasheet Section 2, C-series devices exhibit very low dynamic impedance at low currents and hard breakdown knee-distinct from B-series variants that trade leakage for faster switching and noise reduction.
Is Pin 2 (n.c.) electrically isolated or internally bonded?
Pin 2 is fully unconnected-no internal bond wire, die attachment, or metallization links it to the silicon die. The SOT23 outline drawing (Figure 9) and pinning table confirm it is a mechanical dummy lead; PCB layout must leave it unconnected and avoid solder mask openings or copper traces to prevent unintended coupling or assembly defects.
