Product details
Overview
HPZR-C3V0-Q from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 5.5 W total power dissipation at Tsp = 75 °C, with nominal 3.0 V working voltage (±5 % tolerance), 1.0 V forward voltage at 100 mA, and 30 kV ESD rating per IEC 61000-4-2 - used for low-current regulation in automotive body control modules.
For engineers reviewing the HPZR-C3V0-Q datasheet, HPZR-C3V0-Q pinout, HPZR-C3V0-Q application, or HPZR-C3V0-Q equivalent, this device supports stable voltage clamping in space-constrained automotive PCBs where thermal performance, AEC-Q101 qualification, and high ESD immunity are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown to maintain a stable 3.0 V reference under varying load and temperature conditions. Its 800 W non-repetitive peak power capability enables robust transient suppression, while its 18 K/W junction-to-solder-point thermal resistance ensures efficient heat transfer through the cathode tab.
The device uses a planar silicon process qualified to AEC-Q101, with specified differential resistance of ≤ 8.0 Ω at IZ = 100 mA and reverse current ≤ 80 µA at VR = 2.8 V - confirming tight regulation and low leakage for precision biasing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 2.80 V to 3.20 V at IZ = 100 mA - defines precise clamping threshold for 3.3 V rail protection |
| Total Power Dissipation | 5500 mW at Tsp = 75 °C (zero lead length) - enables sustained operation in thermally demanding automotive environments |
| Forward Voltage | ≤ 1.0 V at IF = 100 mA - ensures minimal conduction loss during forward-biased fault conditions |
| ESD Rating | 30 kV contact discharge per IEC 61000-4-2 - provides immunity against human-body ESD events on exposed PCB traces |
| Differential Resistance | ≤ 8.0 Ω at IZ = 100 mA - guarantees low dynamic impedance for stable regulation under load transients |
| Junction Temperature | −55 °C to +175 °C - supports operation across full automotive ambient range including under-hood locations |
| Package | CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm - ultra-low-profile SMD footprint compatible with automated reflow assembly |
Pinout & Package
HPZR-C3V0-Q uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package with cathode tab thermal pad. The marking bar identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; serves as primary thermal path via soldered tab to PCB copper |
| 2 | Anode (A) | Connected to ground or reference potential; completes reverse-bias regulation path |
Key Features
| Feature | Design Value |
|---|---|
| High Power Handling | 5.5 W DC dissipation at Tsp = 75 °C - allows use in higher-current regulation without external heatsinking |
| AEC-Q101 Qualified | Stress-tested for automotive discrete semiconductors - ensures reliability in vibration-prone, high-temperature vehicle systems |
| Low Profile Package | SOD123W footprint with 1.0 mm max height - enables placement in tight clearance zones such as connector interfaces or sensor housings |
| High ESD Robustness | 30 kV contact discharge rating - eliminates need for additional TVS protection in many low-energy signal lines |
| Tight Voltage Tolerance | ±5 % nominal 3.0 V - reduces design margin requirements for 3.3 V logic supply monitoring and reset circuits |

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 rating, SOT23 package, RZ = 90 Ω at 5 mA - lower power, higher impedance | Not suitable for >100 mA regulation or automotive under-hood thermal environments | Select only for low-power, cost-sensitive consumer PCBs with ample thermal margin |
| MMSZ4675 | 500 mW rating, SOD123 package, VZ = 3.0 V ±5 %, RZ = 15 Ω at 20 mA | Lacks AEC-Q101 qualification and 30 kV ESD rating - requires supplemental protection in automotive designs | Acceptable for industrial control boards where qualification and ESD are not mandated |

FAQ
What is the maximum continuous reverse current the HPZR-C3V0-Q can sustain at 25 °C ambient?
At Tamb = 25 °C with standard FR4 PCB mounting (1 cm² cathode pad), HPZR-C3V0-Q supports up to 1154 mW total power dissipation. With VZ ≈ 3.0 V, this corresponds to a maximum continuous reverse current of approximately 385 mA - confirmed by Ptot/VZ calculation and validated in Table 4 limiting values.
How does the cathode tab improve thermal performance compared to standard SOD123 devices?
The CFP3 package's exposed cathode tab provides a direct thermal path to the PCB, achieving Rth(j-sp) = 18 K/W - significantly lower than typical SOD123 Rth(j-a) values (>200 K/W). This allows 3× higher power handling at the same solder point temperature, verified in Table 8 thermal characteristics.
Can HPZR-C3V0-Q replace older 1N4728A Zeners in existing designs?
No - HPZR-C3V0-Q is not a drop-in replacement for 1N4728A. It uses CFP3 (SOD123W) packaging versus DO-41, has different thermal mounting requirements (cathode-tab soldering), and operates at higher power density. PCB layout and thermal validation must be updated per Figure 10 and 11 footprints.
Is the 30 kV ESD rating applicable to both anode and cathode terminals?
No - the 30 kV IEC 61000-4-2 contact discharge rating applies specifically to the cathode terminal (soldering point), as stated in Table 6 footnote [2]. The anode exhibits lower ESD immunity and must be protected separately if exposed to handling discharge paths.
