Product details
Overview
HPZR-C30-QX from Nexperia is a high-power Zener voltage regulator diode with nominal 30 V working voltage (VZ = 28.9–31.9 V at IZ = 1 mA), ±5 % tolerance, 5.5 W DC power dissipation at Tsp = 75 °C, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge), designed for automotive-grade overvoltage clamping and precision regulation in engine control units and ADAS sensor interfaces.
For engineers reviewing the HPZR-C30-QX datasheet, HPZR-C30-QX pinout, HPZR-C30-QX application, or HPZR-C30-QX equivalent, this device delivers verified AEC-Q101 qualification, low-profile CFP3 (SOD123W) packaging, 26 Ω differential resistance at 20 mA, and thermal resistance of 18 K/W from junction to solder point - critical for thermally constrained PCB layouts in automotive power rails.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ tolerance (±5 %) and low dynamic impedance (RZ = 26 Ω @ IZ = 20 mA), enabling stable reference and transient suppression in 12 V/24 V automotive systems. Its 800 W non-repetitive peak power capability (tp ≤ 100 µs) supports surge immunity against load-dump transients.
Thermal design is enabled by dual thermal paths: Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB, while its 30 kV ESD rating ensures robustness during handling and in-circuit operation without external protection circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Working Voltage) | 28.9 V to 31.9 V at IZ = 1 mA - defines precise clamping threshold for 30 V nominal rail protection |
| Ptot (DC Power Dissipation) | 5500 mW @ Tsp = 75 °C (zero lead length) - enables high continuous power handling in compact SMD layout |
| RZ (Differential Resistance) | 26 Ω @ IZ = 20 mA - ensures minimal voltage shift under varying load current, critical for stable regulation |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - eliminates need for external ESD protection in front-end circuits |
| AEC-Q101 Qualified | Qualified for automotive discrete semiconductors - guarantees reliability for under-hood and safety-critical ECUs |
| Rth(j-sp) | 18 K/W - enables direct thermal coupling to copper pour or heatsink pad for efficient heat extraction |
| IR (Reverse Current) | 0.1 µA max @ VR = 26 V - ensures ultra-low leakage in standby and low-power modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30 | 300 mW Ptot, SOT-23 package, RZ = 45 Ω @ 5 mA - lower power, higher impedance | Suitable only for signal-level clamping; cannot sustain automotive load-dump energy | Select when board space is extreme and power <100 mW; not AEC-Q101 qualified |
| 1N5361B | 5 W Ptot, DO-41 through-hole, VZ = 30 V ±5 %, RZ = 35 Ω - larger footprint, no ESD rating | Requires wave-soldering; lacks integrated ESD protection for modern sensor interfaces | Choose for legacy through-hole designs where rework tolerance outweighs SMT density and ESD needs |
Compared with BZX84-C30 and 1N5361B, HPZR-C30-QX uniquely combines AEC-Q101 qualification, 30 kV ESD immunity, and 5.5 W power in an SMD CFP3 package - making it the only option for next-generation automotive electronics requiring simultaneous high reliability, miniaturization, and surge resilience.

FAQ
What is the maximum continuous power dissipation for HPZR-C30-QX at 75 °C solder point temperature?
The HPZR-C30-QX delivers 5500 mW (5.5 W) total power dissipation at Tsp = 75 °C with zero lead length measurement condition, as confirmed in Table 1 of the official Nexperia datasheet Rev. 6. This value assumes direct thermal coupling to PCB copper and is derated linearly above 75 °C per Figure 9.
Does HPZR-C30-QX require external ESD protection in automotive sensor interfaces?
No - HPZR-C30-QX has a certified 30 kV ESD rating per IEC 61000-4-2 (contact discharge), validated on the cathode soldering point. It meets AEC-Q101 requirements for electrostatic robustness and eliminates the need for additional TVS diodes or RC filters in most front-end sensor protection schemes.
How does the differential resistance (RZ) of HPZR-C30-QX impact voltage regulation accuracy?
With RZ = 26 Ω at IZ = 20 mA, HPZR-C30-QX exhibits minimal voltage deviation (<0.52 V) for ±20 mA load current variation. This low impedance ensures tight regulation in shunt reference applications, directly improving ADC reference stability and analog signal fidelity in automotive control loops.
Can HPZR-C30-QX be used in 48 V mild-hybrid vehicle systems?
Yes - its 30 V nominal Zener voltage, 60 V peak clamping capability (per VR = 26 V limit), and 175 °C junction rating make it suitable for auxiliary rail protection in 48 V architectures. It is commonly deployed in DC-DC converter feedback networks and gate driver clamp circuits where fast transient response and thermal resilience are required.
