Product details
Overview
HPZR-C10-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 5.5 W total power dissipation at 75 °C solder point temperature, with nominal working voltage 10 V (9.44–10.40 V at IZ = 1 mA), ±5 % tolerance, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge). It serves as a precision voltage reference or overvoltage clamp in automotive power rails.
For engineers reviewing the HPZR-C10-QX datasheet, HPZR-C10-QX pinout, HPZR-C10-QX application, or HPZR-C10-QX equivalent, this device is selected for stable low-current regulation in space-constrained automotive modules where thermal robustness, AEC-Q101 qualification, and high ESD immunity are mandatory.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable DC reference voltage across its terminals under varying load and line conditions. Its differential resistance of 18.02 Ω at IZ = 20 mA ensures tight regulation stability, while junction-to-solder-point thermal resistance of 18 K/W enables efficient heat transfer to the PCB cathode pad.
The device complies with AEC-Q101 stress testing for discrete semiconductors and supports non-repetitive peak reverse power up to 800 W for pulse durations ≤100 µs. Reverse current remains ≤10 µA at VR = 8.5 V, confirming low leakage in standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 9.44–10.40 V at IZ = 1 mA - defines precise clamping threshold for 12 V automotive systems |
| Total Power Dissipation (Ptot) | 5500 mW @ Tsp = 75 °C (zero lead length) - enables high continuous power handling on compact PCBs |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against human-body ESD events in assembly and field use |
| Differential Resistance (RZ) | 18.02 Ω at IZ = 20 mA - ensures minimal voltage shift under dynamic load changes |
| Forward Voltage (VF) | ≤1 V at IF = 100 mA - limits conduction loss during forward-biased fault conditions |
| Junction Temperature (Tj) | −55 to +175 °C - supports operation in under-hood automotive environments |
| Package | CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm - ultra-low-profile SMD footprint compatible with automated reflow |
Pinout & Package
HPZR-C10-QX uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package with cathode marked by a bar on the body. Thermal performance relies on direct copper pad contact at the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary heat path to PCB; solder pad must be ≥1 cm² tin-plated copper for rated 5.5 W dissipation |
| 2 | Anode (A) | Reference node for reverse-bias operation; connects to ground or lower-potential rail in shunt regulator configuration |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard |
| High ESD immunity | 30 kV contact discharge rating ensures survivability during board handling and in-vehicle electrostatic events |
| Low-profile thermal package | CFP3 (SOD123W) delivers 18 K/W junction-to-solder-point resistance - 3× better than standard SOD-123 |
| Tight voltage tolerance | ±5 % nominal VZ enables accurate clamping without post-production trimming in cost-sensitive modules |
| Low leakage at rated VR | ≤10 µA reverse current at 8.5 V allows minimal standby power draw in always-on vehicle networks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C10 | 300 mW Ptot, SOT23 package, RZ = 20 Ω, no AEC-Q101 qualification | Limited to non-automotive consumer applications; insufficient power for sustained clamp duty | Select only for cost-sensitive, low-power industrial sensors with ambient <85 °C |
| MMSZ5240B | 500 mW Ptot, SOD-123, VZ = 10 V ±5 %, RZ = 17 Ω, AEC-Q200 grade 2 (not Q101) | Lower surge capability (200 W PZSM) and unqualified for discrete semiconductor stress tests | Acceptable for cabin electronics with moderate ESD exposure but not under-hood locations |

FAQ
What is the maximum continuous power dissipation for HPZR-C10-QX at 75 °C solder point temperature?
The HPZR-C10-QX delivers 5500 mW (5.5 W) total power dissipation at Tsp = 75 °C when measured with zero lead length and mounted on an FR4 PCB with a 1 cm² tin-plated copper cathode pad. This value drops linearly above 75 °C per the derating curve in Figure 9 of the datasheet.
How does the 30 kV ESD rating apply to real-world assembly and operation?
The 30 kV rating is measured per IEC 61000-4-2 contact discharge at the cathode soldering point, reflecting survival against worst-case human-body ESD events during PCB handling and connector mating. It does not imply immunity to system-level EFT or surge events, which require additional TVS coordination.
Is HPZR-C10-QX suitable for use as a voltage reference in precision analog circuits?
Yes - with 18.02 Ω differential resistance at 20 mA and ±5 % VZ tolerance, HPZR-C10-QX provides stable regulation for non-critical analog references. For sub-1 % accuracy, external trimming or dedicated bandgap references are recommended; this device targets robustness over ultra-precision.
What PCB layout practices maximize thermal performance for HPZR-C10-QX?
To achieve rated 5.5 W dissipation, use a minimum 1 cm² tin-plated copper pad connected to the cathode (Pin 1) with ≥2 thermal vias to inner/ground planes. Avoid narrow traces; follow the 1.1 mm × 1.1 mm solder land and 0.1 mm stencil thickness specified in Figure 11 for reflow.
