Product details
Overview
HPZR-C3V3X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at nominal 3.3 V with ±5 % tolerance, 60 µA max reverse current at 100 mA test current, and 4.1 W DC power dissipation at 75 °C solder point temperature. It serves as a stable reference or clamp in power supply feedback loops, ESD-protected sensor interfaces, and industrial control I/O conditioning circuits.
For engineers reviewing the HPZR-C3V3X datasheet, HPZR-C3V3X pinout, HPZR-C3V3X application, or HPZR-C3V3X equivalent, this page delivers verified electrical parameters, thermal behavior under PCB mounting conditions, cathode/anode terminal mapping, real-world use cases with design-value context, and validated alternative parts with explicit functional trade-offs.
Technical Context
This device operates as a silicon planar Zener diode with sharp reverse breakdown at 3.3 V (IZ = 100 mA), exhibiting differential resistance of ≤8.0 Ω and forward voltage ≤1.0 V at 100 mA. Its 30 kV IEC 61000-4-2 contact discharge ESD rating enables direct placement at board-level I/O without external protection.
Thermal performance is defined by Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB, enabling 4.1 W dissipation at Tsp = 75 °C. Non-repetitive peak power reaches 800 W for pulses ≤100 µs, supporting transient overvoltage clamping in surge-prone environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.3 V (min 3.10 V, max 3.50 V at IZ = 100 mA); ensures tight regulation for 3.3 V rail monitoring and feedback |
| Reverse Current | ≤60 µA at VR = 1.0 V; guarantees low leakage in standby-critical applications |
| Differential Resistance | ≤8.0 Ω at IZ = 100 mA; maintains stable output under varying load currents |
| Total Power Dissipation | 4100 mW at Tsp = 75 °C (zero lead length); supports high-power regulation without heatsink on compact PCBs |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge; eliminates need for discrete TVS in many front-end protection designs |
| Forward Voltage | ≤1.0 V at IF = 100 mA; enables efficient anode-side biasing in dual-supply clamp configurations |
| Junction Temperature | 150 °C maximum; allows operation in extended-temperature industrial environments |
Pinout & Package
HPZR-C3V3X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for low thermal resistance and automated assembly. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; solder pad provides primary thermal path to PCB |
| 2 | Anode (A) | Connected to ground or lower-potential reference; minimal trace inductance critical for ESD response |
Key Features
| Feature | Design Value |
|---|---|
| 4.1 W DC power handling at Tsp = 75 °C | Enables single-device regulation in space-constrained 3.3 V auxiliary rails without derating or parallel devices |
| 30 kV IEC 61000-4-2 ESD immunity | Reduces BOM count by integrating ESD protection into the regulation element for sensor and communication I/O |
| ±5 % Zener voltage tolerance | Meets industrial-grade accuracy requirements without post-production trimming or calibration |
| Low 8.0 Ω dynamic impedance | Minimizes output voltage shift across 10–100 mA load range, improving ADC reference stability |
| CFP3 (SOD123W) footprint compatibility | Supports drop-in replacement of legacy Zeners while delivering 4× higher power density than SOD-123 |
Applications
| Industrial Sensor Signal Conditioning | 3.3 V Microcontroller Power Rail Clamping |
|---|---|

Use Scenario: Protecting analog outputs of pressure/temperature transducers against ESD and overvoltage during field wiring. IC Role / Device Role / Timing Role: Zener clamp placed between signal line and ground, conducting only during transients >3.3 V. Use Value: 30 kV ESD rating prevents latch-up or damage during connector hot-plug; 60 µA leakage avoids loading 4–20 mA loop. |
Use Scenario: Stabilizing 3.3 V supply to MCU I/O pins during brown-out or switching noise events. IC Role / Device Role / Timing Role: Shunt regulator connected between VDD_IO and GND, absorbing excess energy during voltage spikes. Use Value: 4.1 W dissipation handles 100 ms surges up to 5.5 V without thermal runaway; 8.0 Ω impedance limits overshoot to <50 mV. |
| Programmable Logic Controller (PLC) Digital Input Protection | Automotive Body Control Module (BCM) Reference Divider |
|
Use Scenario: Front-end protection for 24 V digital inputs where optocoupler input LEDs require precise 3.3 V bias. IC Role / Device Role / Timing Role: Zener referenced across LED series resistor to fix forward voltage and stabilize current. Use Value: ±5 % tolerance ensures consistent LED drive across temperature; 150 °C junction rating supports under-hood ambient conditions. |
Use Scenario: Generating accurate 3.3 V reference from 12 V battery via resistive divider in non-safety-critical BCM subsystems. IC Role / Device Role / Timing Role: Zener replaces passive divider's upper resistor to maintain ratio stability under load variation. Use Value: Low 60 µA leakage minimizes divider current error; 1.0 V VF enables bidirectional clamping if reverse-biased during load dump. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V3 | 300 mW Ptot, SOT23 package, RZ = 90 Ω, IR = 5 µA @ 1 V | Limited to low-power biasing; unsuitable for >100 mA load regulation or ESD-heavy environments | Select when board space is constrained and power <0.3 W; avoid for clamping or industrial I/O |
| PZM3.3NB | 500 mW Ptot, SOD-323, VZ = 3.3 V ±5 %, RZ = 15 Ω, ESD = 8 kV | Lower ESD rating requires external TVS; thermal resistance too high for sustained 4.1 W dissipation | Choose for cost-sensitive consumer designs with benign ESD environment and <0.5 W average load |
Compared with BZX84-C3V3 and PZM3.3NB, HPZR-C3V3X delivers 13.7× higher power capability, 3.8× lower dynamic impedance, and 3.8× higher ESD immunity-enabling consolidation of regulation and protection functions in harsh industrial and automotive-adjacent applications without thermal derating or secondary components.

FAQ
What is the maximum continuous current HPZR-C3V3X can regulate at 3.3 V?
At 3.3 V Zener voltage and ambient temperature ≤25 °C on FR4 PCB with 1 cm² cathode pad, HPZR-C3V3X supports up to 291 mA continuous current (962 mW ÷ 3.3 V). At Tsp = 75 °C, it sustains 1242 mA (4100 mW ÷ 3.3 V), limited by thermal resistance to solder point (18 K/W).
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD-123?
The CFP3 package features wider cathode leads and optimized internal die attach, reducing Rth(j-sp) to 18 K/W versus ~40 K/W for standard SOD-123. This 55 % lower thermal resistance enables 4.1 W dissipation at Tsp = 75 °C-more than quadruple the power handling of legacy equivalents in the same footprint.
Can HPZR-C3V3X be used in avalanche mode for transient suppression?
No. HPZR-C3V3X is a Zener-regulated diode optimized for stable DC regulation, not transient clamping. Its 800 W non-repetitive peak power rating applies only to square-wave pulses ≤100 µs; for surge suppression, dedicated TVS diodes like PESD5V0S1BA are recommended due to faster response and guaranteed clamping voltage.
Is HPZR-C3V3X compliant with automotive AEC-Q200 standards?
No. HPZR-C3V3X is not AEC-Q200 qualified. While its 150 °C junction rating and 30 kV ESD rating meet some automotive environmental thresholds, Nexperia explicitly states in the datasheet that non-automotive-qualified products are unsuitable for safety-critical or automotive use without additional validation by the customer.
