Product details
Overview
HPZR-C7V0X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision DC voltage clamping and regulation at 7.0 V nominal working voltage (6.67–7.37 V at IZ = 10 mA), with 4.1 W total power dissipation at Tsp = 75 °C and 30 kV ESD rating per IEC 61000-4-2 (contact discharge), used in industrial power supply rail stabilization.
For engineers reviewing the HPZR-C7V0X datasheet, HPZR-C7V0X pinout, HPZR-C7V0X application, or HPZR-C7V0X equivalent, key selection criteria include its 6.0 Ω differential resistance at IZ = 20 mA, 400 µA max reverse current at VR, 1 V forward voltage at 100 mA, and thermal resistance of 18 K/W junction-to-solder-point - critical for high-reliability overvoltage protection in compact SMD designs.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse breakdown characteristics, optimized for stable voltage reference and transient suppression in low-current regulation circuits. Its 7.0 V nominal Zener voltage is specified at 10 mA test current, with ±5 % tolerance and 6.0 Ω dynamic impedance ensuring tight regulation under load variation.
The CFP3 package enables high thermal efficiency via direct cathode tab soldering, achieving 18 K/W Rth(j-sp) when mounted on FR4 PCB with 1 cm² cathode pad. It supports non-repetitive peak power up to 800 W (tp ≤ 100 µs) and withstands 50 A IFSM (8.3 ms half-sine), making it suitable for surge-limited clamp applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 6.67–7.37 V at IZ = 10 mA - defines precise clamping threshold for 7 V rail protection |
| Differential Resistance RZ | 6.0 Ω at IZ = 20 mA - ensures minimal output voltage shift under current load changes |
| Reverse Current IR | ≤ 400 µA at VR - guarantees low leakage during standby operation |
| Total Power Dissipation Ptot | 4100 mW at Tsp = 75 °C (zero lead length) - enables high-power regulation without heatsink in space-constrained layouts |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - provides robust handling immunity for automated assembly and field operation |
| Forward Voltage VF | ≤ 1 V at IF = 100 mA - minimizes conduction loss in series-pass or crowbar configurations |
| Junction Temperature | 150 °C maximum - supports extended operation in industrial ambient environments |
Pinout & Package
HPZR-C7V0X uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package measuring 2.6 mm × 1.7 mm × 1.0 mm, featuring a flat, low-profile design with exposed cathode tab for enhanced thermal conduction. The marking bar identifies the cathode end.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output or ground return path; thermally coupled to PCB pad for heat extraction |
| 2 | Anode (A) | Connected to unregulated input or positive rail; reverse-biased during Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Handling | 4.1 W DC dissipation at 75 °C solder point - eliminates need for external heatsinking in most 7 V clamp designs |
| Precision Zener Tolerance | ±5 % nominal voltage - enables accurate voltage setting without post-production trimming |
| Ultra-High ESD Robustness | 30 kV IEC 61000-4-2 contact discharge - reduces risk of EOS damage during board handling and reflow |
| Low Dynamic Impedance | 6.0 Ω at 20 mA - maintains < ±30 mV regulation error across typical load current swings |
| Compact Thermal Interface | 18 K/W Rth(j-sp) - allows efficient heat transfer directly from junction to solder joint on standard FR4 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V0 | 300 mW Ptot, SOT23 package, RZ = 20 Ω at 5 mA | Lower power, higher impedance - suitable only for signal-level referencing, not rail clamping | Select when board space is constrained and power dissipation < 300 mW; avoid for >10 mA load regulation |
| MMSZ5234B | 500 mW Ptot, SOD-123, VZ = 7.5 V (±5 %), RZ = 7 Ω at 20 mA | Higher nominal voltage, lower power rating - requires derating above 60 °C ambient | Choose if 7.5 V threshold is acceptable and thermal margin permits 500 mW operation on standard FR4 |
Compared with BZX84-C7V0 and MMSZ5234B, HPZR-C7V0X delivers 8× higher power capability and 3× lower thermal resistance, enabling direct integration into 7 V power rail protection without auxiliary cooling - critical for high-density industrial PCBs.

FAQ
What is the maximum continuous current HPZR-C7V0X can regulate at 75 °C?
At Tsp = 75 °C with zero lead length, HPZR-C7V0X sustains 4.1 W total power dissipation. With a nominal Zener voltage of 7.0 V, this corresponds to a maximum continuous regulation current of approximately 586 mA (4.1 W ÷ 7.0 V). Derating applies above 75 °C per Fig. 9 in the datasheet.
Does HPZR-C7V0X require a heatsink for 4.1 W operation?
No external heatsink is required. The CFP3 package achieves 18 K/W thermal resistance from junction to solder point when mounted on an FR4 PCB with a 1 cm² cathode pad, allowing full 4.1 W dissipation at Tsp = 75 °C using only standard PCB copper area.
How does the 30 kV ESD rating impact board-level reliability?
The 30 kV IEC 61000-4-2 contact discharge rating means HPZR-C7V0X can absorb electrostatic events common in manufacturing and field service without failure. This eliminates the need for additional TVS devices in many input protection schemes, reducing BOM count and layout area.
Can HPZR-C7V0X be used in parallel for higher current handling?
Parallel operation is not recommended due to mismatch in Zener voltage and dynamic impedance between units, which causes current imbalance and potential thermal runaway. For higher current needs, select a single higher-power device or implement active current-sharing circuitry.
