Product details
Overview
HPZR-C7V6-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 7.22 V to 7.98 V nominal working voltage at IZ = 20 mA, with 6.5 Ω differential resistance, 250 µA max reverse current, and 5.5 W total power dissipation at Tsp = 75 °C. It serves as a precision shunt voltage reference in automotive power rail stabilization circuits.
For engineers reviewing the HPZR-C7V6-QX datasheet, HPZR-C7V6-QX pinout, HPZR-C7V6-QX application, or HPZR-C7V6-QX equivalent, this device is selected for high-reliability automotive voltage clamping, ESD-robust biasing networks, and thermally constrained board-level regulation where AEC-Q101 qualification and 30 kV IEC 61000-4-2 contact discharge rating are required.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (~±5 %), optimized for stable DC voltage reference under varying load and temperature conditions. Its low RZ of 6.5 Ω ensures minimal output voltage drift across operating current range.
Thermal design is enabled by dual thermal paths: Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB, supporting high ambient operation up to +175 °C junction temperature. The CFP3 package's flat lead geometry enhances heat transfer to PCB copper pads.
Key Specifications

|---|---|
| VZ (Working Voltage) | 7.22 V to 7.98 V at IZ = 20 mA - defines regulated output voltage window for precision biasing |
| RZ (Differential Resistance) | 6.5 Ω - ensures <13 mV output shift per 2 mA load change, critical for stable reference accuracy |
| IR (Reverse Current) | ≤250 µA at VR = 7.0 V - guarantees low leakage in standby or low-power modes |
| Ptot | 5500 mW at Tsp = 75 °C - enables sustained regulation under high ambient thermal stress |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - protects against assembly- and field-level electrostatic events |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress |
| Package | CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm - ultra-low profile SMD footprint compatible with automated reflow |

FAQ
What is the maximum continuous reverse current the HPZR-C7V6-QX can handle without degradation?
The device supports up to 400 mA forward current (IF) per limiting values, but as a Zener regulator, its continuous reverse operating current is defined by power derating. At Tamb = 25 °C on FR4 PCB, max IZ is ~150 mA (1154 mW ÷ 7.6 V); at Tsp = 75 °C, it rises to ~720 mA (5500 mW ÷ 7.6 V), provided thermal design maintains junction temperature ≤175 °C.
Does HPZR-C7V6-QX require an external series resistor in standard shunt regulation configurations?
Yes-a series current-limiting resistor is mandatory to set operating IZ within safe limits. For example, with 12 V input and target IZ = 50 mA, RSERIES = (12 V − 7.6 V) ÷ 0.05 A = 88 Ω. Resistor power rating must exceed IZ² × R to avoid thermal runaway under worst-case input surges.
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD-123?
The CFP3 variant features wider, flattened leads that increase copper pad contact area and reduce thermal resistance to solder point (Rth(j-sp) = 18 K/W vs. ~35 K/W for standard SOD-123). This allows 3.8× higher DC power dissipation (5.5 W vs. ~1.4 W) at Tsp = 75 °C when mounted on 1 cm² cathode pad per datasheet condition [4].
Can HPZR-C7V6-QX be used in parallel for higher current capability?
No-Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal instability when paralleled. For higher current, use a single higher-rated device or implement active regulation with a pass transistor; parallel connection is not recommended or characterized in the datasheet.
