Product details
Overview
HPZR-C7V6X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision DC voltage clamping and regulation in power supply rails and protection circuits. It delivers 7.22 V to 7.98 V nominal Zener voltage at IZ = 20 mA, with 250 µA max reverse current, 6.5 Ω typical differential resistance, and 4.1 W total power dissipation at Tsp = 75 °C - suitable for industrial power converters and overvoltage protection in 8–12 V systems.
For engineers reviewing the HPZR-C7V6X datasheet, HPZR-C7V6X pinout, HPZR-C7V6X application, or HPZR-C7V6X equivalent, key selection criteria include its ±5 % tolerance, 30 kV ESD rating per IEC 61000-4-2 (contact), 800 W non-repetitive peak power capability, and thermal resistance of 18 K/W junction-to-solder-point - critical for compact, thermally constrained PCB layouts.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias regulation under continuous and transient conditions. Its design targets low-profile SMD applications where space and thermal performance are constrained, leveraging the CFP3 package's exposed cathode tab for enhanced heat transfer to PCB copper.
It exhibits a sharp Zener knee with 6.5 Ω differential resistance at 20 mA test current and maintains ≤250 µA leakage up to 7.0 V reverse bias - enabling reliable clamping in 8–12 V automotive auxiliary rails and industrial sensor interface protection circuits without significant quiescent loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 7.22 V to 7.98 V at IZ = 20 mA - defines precise clamping threshold for 8 V nominal systems |
| Reverse Current (IR) | ≤250 µA at VR = 7.0 V - ensures minimal standby leakage in always-on protection circuits |
| Differential Resistance (RZ) | 6.5 Ω at IZ = 20 mA - provides tight regulation against load-induced voltage shifts |
| Total Power Dissipation (Ptot) | 4100 mW at Tsp = 75 °C (zero lead length) - enables high steady-state power handling on minimal copper area |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - protects downstream circuitry from human-body ESD events |
| Non-repetitive Peak Power (PZSM) | 800 W for tp ≤ 100 µs - suppresses short-duration transients like inductive kickback |
| Junction Temperature (Tj) | −55 °C to +150 °C - supports operation in extended-temperature industrial environments |
Pinout & Package
HPZR-C7V6X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, exposed cathode tab for thermal conduction. The marking bar denotes the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output or ground reference; exposed metal tab serves as primary thermal path to PCB |
| 2 | Anode (A) | Connected to unregulated input or positive rail; reverse-biased during regulation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Density | 4.1 W dissipation in 2.6 mm × 1.7 mm footprint - reduces board area vs. legacy DO-214AC packages |
| Low Thermal Resistance | 18 K/W junction-to-solder-point - enables direct thermal coupling to 1 cm² cathode pad on FR4 |
| Precision Zener Tolerance | ±5 % nominal voltage - eliminates need for post-production trimming in mid-accuracy power rails |
| Robust ESD Immunity | 30 kV contact discharge rating - meets IEC 61000-4-2 Level 4 without external TVS staging |
| Transient Surge Capability | 800 W non-repetitive peak power - clamps 50 A surge (8.3 ms half-sine) without failure |
Applications
| Industrial Power Supply Regulation | Automotive Auxiliary Rail Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V5 | 7.5 V nominal, 300 mW Ptot, SOT23 package, RZ = 15 Ω | Limited to low-power signal-level clamping; insufficient for >100 mA regulation | Select only for space-constrained signal conditioning where thermal budget <0.3 W |
| 1N4735A | 6.2 V nominal, 1 W Ptot, DO-41 through-hole, RZ = 7 Ω | Requires PCB real estate and wave-solder process; no ESD rating specified | Choose only for legacy through-hole designs or when 6.2 V regulation is mandatory |
Compared with BZX84-C7V5 and 1N4735A, HPZR-C7V6X uniquely combines 4.1 W power handling, 30 kV ESD immunity, and 6.5 Ω regulation impedance in an ultra-low-profile SMD package - making it the sole option for high-current, high-reliability Zener regulation in modern industrial and automotive PCBs.

FAQ
What is the maximum continuous forward current rating for HPZR-C7V6X?
HPZR-C7V6X is a Zener diode intended for reverse-bias operation; its absolute maximum forward current is 400 mA per limiting values table. However, forward conduction is not a functional operating mode - sustained forward bias exceeds safe operating area and risks thermal runaway. Design must ensure reverse bias during regulation.
Can HPZR-C7V6X be used in parallel for higher power handling?
No - Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging if paralleled. The device is characterized for single-diode operation only. For >4.1 W requirements, use a dedicated high-power regulator IC or discrete MOSFET-based shunt topology with active current sharing.
What PCB layout practices maximize thermal performance for HPZR-C7V6X?
Maximize thermal performance by using a ≥1 cm² tin-plated copper pad connected directly to the cathode tab (Pin 1), with ≥2 thermal vias (0.3 mm diameter, filled) routed to inner or backside ground planes. Avoid solder mask over the cathode pad and maintain ≥0.5 mm clearance from adjacent components to prevent localized hot spots.
Is HPZR-C7V6X qualified for automotive applications per AEC-Q200?
No - HPZR-C7V6X is not AEC-Q200 qualified. The datasheet explicitly states "non-automotive qualified products" and prohibits use in safety-critical automotive systems. While its 150 °C Tj and 30 kV ESD rating exceed some automotive thresholds, formal qualification testing (temperature cycling, humidity bias, vibration) has not been performed or certified by Nexperia.
