Product details
Overview
HPZR-C6V7-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision voltage clamping and regulation in automotive power rails. It delivers 6.7 V nominal Zener voltage at 10 mA, with ±5 % tolerance, 400 μA max reverse current at rated voltage, 5.0 Ω typical differential resistance at 20 mA, and 5.5 W DC power dissipation at 75 °C solder point temperature - used in engine control unit (ECU) supply rail protection.
For engineers reviewing the HPZR-C6V7-QX datasheet, HPZR-C6V7-QX pinout, HPZR-C6V7-QX application, or HPZR-C6V7-QX equivalent, key selection criteria include Zener voltage accuracy under automotive ambient conditions, thermal resistance to solder point (18 K/W), AEC-Q101 qualification status, and ESD robustness (30 kV contact discharge per IEC 61000-4-2).
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias voltage regulation under transient and steady-state load conditions. Its design targets low dynamic impedance (42.40 Ω at 20 mA) and tight voltage tolerance (6.40–7.00 V) to maintain reference integrity across temperature and current variations in automotive subsystems.
The CFP3 package enables high thermal efficiency via direct cathode tab conduction to PCB copper, achieving 18 K/W junction-to-solder-point thermal resistance. It supports non-repetitive peak power dissipation up to 800 W for ≤100 µs pulses, enabling surge suppression in 12 V vehicle networks without external snubbers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 6.40 V to 7.00 V at IZ = 10 mA - defines regulated output range for 12 V system biasing |
| Differential Resistance (RZ) | 42.40 Ω at IZ = 20 mA - ensures minimal output voltage shift under load transients |
| Reverse Current (IR) | ≤ 400 μA at VR = 6.7 V - guarantees low quiescent leakage in always-on circuits |
| Total Power Dissipation (Ptot) | 5500 mW at Tsp = 75 °C (zero lead length) - enables high continuous power handling on compact PCBs |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - protects against human-body and assembly-line ESD events |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports operation in under-hood environments including exhaust proximity |
| AEC-Q101 Qualified | Yes - validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and TCT |
Pinout & Package
HPZR-C6V7-QX uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by bar on top surface. Thermal performance relies on cathode tab soldering to ≥1 cm² copper pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Primary heat path and voltage reference node; connects to regulated rail ground or return |
| 2 (A) | Anode | Input terminal for unregulated supply; reverse-biased during regulation operation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Handling | 5.5 W DC dissipation at 75 °C solder point - eliminates need for derating in compact automotive modules |
| Tight Voltage Tolerance | ±5 % nominal VZ - reduces calibration overhead in safety-critical sensor biasing |
| Automotive Qualification | AEC-Q101 compliant - meets stress test requirements for under-hood deployment without additional qualification |
| ESD Robustness | 30 kV contact discharge rating - withstands factory handling and field service without protection circuitry |
| Low Thermal Resistance | 18 K/W junction-to-solder-point - enables efficient heat transfer through cathode tab to PCB copper |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C6V8-HE3-08 | 6.8 V nominal, ±5 %, SOT23 package, Ptot = 300 mW at 25 °C | Limited to low-power logic rails; unsuitable for automotive power rail clamping due to thermal derating | Select only for non-automotive, low-current (<50 mA) reference use with board-level heatsinking |
| MMSZ5234ET1G | 6.2 V nominal, ±5 %, SOD123 package, Ptot = 500 mW at 25 °C | Lower power rating and no AEC-Q101 qualification; lacks 30 kV ESD rating | Acceptable for industrial control boards where AEC compliance and surge immunity are not required |
Compared with BZX84-C6V8-HE3-08 and MMSZ5234ET1G, HPZR-C6V7-QX provides 11× higher DC power capability, AEC-Q101 validation, and integrated 30 kV ESD protection - making it uniquely suitable for automotive power rail stabilization without supplemental components.

FAQ
What is the maximum continuous power dissipation of HPZR-C6V7-QX at 105 °C ambient?
At 105 °C ambient, HPZR-C6V7-QX must be derated using its thermal resistance curve. With Rth(j-a) = 70 K/W on ceramic PCB, maximum Ptot drops to approximately 1.0 W to maintain Tj ≤ 175 °C. For sustained 5.5 W operation, solder point temperature must be held at ≤75 °C via adequate copper area and airflow.
Does HPZR-C6V7-QX require external series resistance for safe operation?
Yes - a current-limiting resistor is mandatory to prevent exceeding IF = 400 mA maximum forward current and to set operating current within the 10–100 mA range where Zener voltage and dynamic resistance are specified. Resistor value is calculated based on input voltage, desired Zener current, and VZ tolerance band.
How does the cathode marking align with PCB footprint for CFP3 (SOD123W)?
The cathode bar on HPZR-C6V7-QX aligns with Pin 1 of the official Nexperia CFP3 footprint (Fig. 11), which places the larger solder land on the cathode side (1.4 mm × 2.1 mm) versus the anode side (1.2 mm × 1.6 mm). Misalignment causes reverse bias failure and thermal runaway.
Is HPZR-C6V7-QX compatible with lead-free reflow profiles?
Yes - HPZR-C6V7-QX is qualified for standard lead-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The CFP3 package uses matte tin plating and passes mechanical and intermetallic integrity tests after JEDEC moisture sensitivity level 1 handling.
