Product details
Overview
HPZR-C3V0X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at 3.0 V nominal working voltage with ±5 % tolerance. It delivers 4.1 W total power dissipation at Tsp = 75 °C, supports 800 W non-repetitive peak power (tp ≤ 100 µs), and features 30 kV ESD rating per IEC 61000-4-2 (contact discharge), enabling robust operation in industrial power supply rails and sensor biasing circuits.
For engineers reviewing the HPZR-C3V0X datasheet, HPZR-C3V0X pinout, HPZR-C3V0X application, or HPZR-C3V0X equivalent, this device is selected for stable low-current voltage reference tasks where thermal performance under zero-lead-length mounting, tight Zener voltage tolerance, and high ESD immunity are critical design requirements.
Technical Context
This Zener diode operates in reverse breakdown mode with a specified test current of 100 mA for the 3.0 V variant, delivering a typical differential resistance of 8.0 Ω and reverse current ≤80 µA at VR = 1.0 V. Its thermal design relies on junction-to-solder-point resistance of 18 K/W, optimized for direct cathode pad thermal coupling to PCB copper.
The device adheres to IEC 60134 absolute maximum ratings, with 150 °C max junction temperature and 50 A non-repetitive peak forward current (tp = 8.3 ms). Its pulse power capability follows a defined inverse-time curve-800 W at 100 µs, scaling down to ~100 W at 1 ms-enabling transient overvoltage clamping without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.0 V (min 2.80 V, max 3.20 V at IZ = 100 mA); enables precise low-voltage reference in 3.3 V rail monitoring or analog sensor biasing. |
| Total Power Dissipation | 4100 mW @ Tsp = 75 °C (zero lead length); supports sustained regulation in compact SMT layouts without forced airflow. |
| Differential Resistance | 8.0 Ω @ IZ = 100 mA; ensures minimal output voltage shift under load variation in feedback or reference paths. |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge; protects against handling and system-level ESD events without external TVS. |
| Forward Voltage | ≤1.0 V @ IF = 100 mA; allows safe conduction during reverse-polarity fault conditions without excessive heating. |
| Thermal Resistance (j-sp) | 18 K/W; confirms efficient heat transfer from junction to solder point, critical for reliability in thermally constrained PCBs. |
| Non-repetitive Peak Power | 800 W @ tp ≤ 100 µs; provides surge suppression capability for short-duration transients like inductive kickback. |
Pinout & Package
HPZR-C3V0X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, low-profile design optimized for automated assembly and thermal pad coupling. Cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; requires ≥1 cm² copper pad for thermal management and rated 4.1 W dissipation. |
| 2 | Anode (A) | Connected to ground or lower potential; serves as return path during Zener conduction and forward conduction faults. |
Key Features
| Feature | Design Value |
|---|---|
| High Power Density | 4.1 W DC dissipation in 2.6 mm × 1.7 mm footprint-enables space-constrained regulation without heatsinks. |
| Tight Voltage Tolerance | ±5 % nominal Zener voltage-reduces need for post-calibration in precision reference and feedback divider networks. |
| ESD-Robust Construction | 30 kV IEC 61000-4-2 contact discharge rating-eliminates need for discrete ESD protection in board-level interfaces. |
| Low Differential Resistance | 8.0 Ω at 100 mA-maintains stable regulation across varying load currents in analog front-ends and sensor excitation. |
| Optimized Thermal Path | 18 K/W Rth(j-sp)-leverages cathode pad as primary thermal conduit, simplifying thermal design on FR4 PCBs. |

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-C3V0 | 300 mW Ptot, SOT23 package, RZ = 90 Ω @ 5 mA; no 30 kV ESD rating. | Suitable only for signal-level references (<10 mA), not power rail clamping or industrial environments. | Select when cost and board area are prioritized over power handling and ESD robustness. |
| MMSZ4675 | 500 mW Ptot, SOD123 package, VZ = 3.0 V ±5 %, RZ = 15 Ω @ 20 mA; ESD rating unspecified. | Limited to low-duty-cycle biasing; lacks thermal derating data for continuous 4.1 W operation. | Choose for legacy designs using standard SOD123 footprints where peak power demands are <100 W. |
Compared with BZX84-C3V0 and MMSZ4675, HPZR-C3V0X uniquely combines 4.1 W DC power handling, 30 kV ESD immunity, and 18 K/W thermal resistance-making it the only option capable of replacing discrete TVS + Zener combos in space- and reliability-critical industrial power rails.

FAQ
What is the maximum continuous current HPZR-C3V0X can regulate at 3.0 V?
At 25 °C ambient and mounted on an FR4 PCB with 1 cm² cathode pad, HPZR-C3V0X supports up to 400 mA forward current and regulates stably at 3.0 V with ≤80 µA reverse leakage at 1.0 V. For continuous Zener operation, the 100 mA test current aligns with its 4.1 W thermal limit at Tsp = 75 °C-yielding ~136 mA max average Zener current under those conditions.
Does HPZR-C3V0X require a heatsink for 4.1 W operation?
No external heatsink is required. The 4.1 W rating is specified at Tsp = 75 °C with zero lead length and a 1 cm² tin-plated copper pad under the cathode-leveraging the device's 18 K/W junction-to-solder-point thermal resistance. Standard FR4 PCB layout with adequate copper area fully satisfies thermal requirements.
How does the 30 kV ESD rating impact system-level design?
The 30 kV IEC 61000-4-2 contact discharge rating applies directly to the cathode terminal and eliminates the need for external ESD protection components in most industrial interfaces. This reduces BOM count, PCB area, and parasitic capacitance-critical for high-impedance reference nodes and fast-switching control signals.
Can HPZR-C3V0X be used in place of a standard 3.3 V Zener diode?
No-it is a 3.0 V nominal Zener (2.80–3.20 V range), not 3.3 V. Substituting it for a 3.3 V part would cause under-regulation in circuits relying on that exact threshold, such as 3.3 V microcontroller reset detection. Always verify VZ min/max against system margin requirements before substitution.
