Product details
Overview
HPZR-C7V0-Q from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 7.0 V nominal working voltage (6.67–7.37 V at IZ = 10 mA), 5.5 W total power dissipation at Tsp = 75 °C, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge). It serves as a precision voltage reference and overvoltage clamp in automotive power rails and low-current regulation circuits.
For engineers reviewing the HPZR-C7V0-Q datasheet, HPZR-C7V0-Q pinout, HPZR-C7V0-Q application, or HPZR-C7V0-Q equivalent, this device is selected for stable 7 V regulation under transient surge conditions, high ESD robustness in harsh environments, thermal performance on FR4 PCBs, and AEC-Q101 qualification for automotive use.
Technical Context
This Zener diode operates in reverse breakdown mode with a tightly controlled 7.0 V nominal Zener voltage (±4.4% tolerance), differential resistance of 4.77 Ω at IZ = 20 mA, and reverse current ≤400 μA at VR = 5.6 V. Its non-repetitive peak power dissipation reaches 800 W for pulses ≤100 µs.
Thermal design is enabled by Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB - critical for sustained operation in engine control units and body electronics where ambient temperatures exceed 105 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 7.0 V (6.67–7.37 V at IZ = 10 mA); enables precise 7 V rail clamping or reference generation |
| Total Power Dissipation | 5500 mW @ Tsp = 75 °C (zero lead length); supports continuous regulation in thermally constrained automotive modules |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge; protects against human-body ESD events in assembly and field operation |
| Differential Resistance | 4.77 Ω at IZ = 20 mA; ensures low dynamic impedance for stable regulation under load transients |
| Reverse Current | ≤400 μA at VR = 5.6 V; guarantees minimal leakage in standby mode for battery-sensitive systems |

| AEC-Q101 Qualified | Qualified for automotive applications; validated for temperature cycling, HTRB, and ESD stress per AEC standard |
Pinout & Package
HPZR-C7V0-Q uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package with cathode-marked top-side bar. Thermal performance relies on direct cathode pad soldering to PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output or ground return; marking bar identifies this terminal; primary thermal path to PCB |
| 2 | Anode (A) | Connected to input or unregulated rail; reverse-biased during Zener operation; no thermal conduction path |
Key Features
| Feature | Design Value |
|---|---|
| High Surge Withstand | 800 W non-repetitive peak power (tp ≤ 100 µs) enables protection against ISO 7637-2 pulse 1/2a/5a transients |
| Automotive-Grade Reliability | AEC-Q101 qualification confirms suitability for under-hood ECUs, lighting modules, and ADAS sensors |
| Low Thermal Resistance | Rth(j-sp) = 18 K/W to solder point allows >5 W dissipation without external heatsink on standard FR4 |
| Tight Voltage Tolerance | ±4.4% (6.67–7.37 V) at IZ = 10 mA supports accurate 7 V reference in feedback loops |
| ESD-Hardened Construction | 30 kV contact discharge rating eliminates need for external TVS in many infotainment and gateway designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C7V0 | 300 mW Ptot, SOT23 package, ±5% tolerance, RZ = 15 Ω | Not AEC-Q101 qualified; limited to consumer-grade 7 V reference, not automotive surge suppression | Select only for cost-sensitive non-automotive applications with <100 mW average dissipation |
| MMSZ5233B | 500 mW Ptot, SOD-123 package, ±5% tolerance, RZ = 10 Ω, no AEC-Q101 or 30 kV ESD rating | Suitable for industrial power supplies but lacks automotive qualification and high-surge capability | Choose when board space permits larger SOD-123 and system-level ESD protection is already implemented |
Compared with BZX84-C7V0 and MMSZ5233B, HPZR-C7V0-Q delivers 11× higher power handling, AEC-Q101 compliance, and industry-leading 30 kV ESD immunity - making it the sole choice for automotive 7 V regulation where reliability under surge and thermal stress is mandatory.

FAQ
What is the maximum continuous power dissipation for HPZR-C7V0-Q on a standard FR4 PCB?
At ambient temperature ≤25 °C on FR4 with single-sided 1 cm² cathode pad, HPZR-C7V0-Q sustains 1154 mW continuously. At solder point temperature ≤75 °C (measured zero lead length), it handles 5500 mW - verified per datasheet Table 1 and Figure 9.
Does HPZR-C7V0-Q require external heat sinking in automotive under-hood applications?
No external heatsink is required. With Rth(j-sp) = 18 K/W to solder point and Rth(j-a) = 70 K/W on ceramic PCB, the device dissipates 5.5 W at Tsp = 75 °C using only the cathode pad thermal connection - confirmed in Thermal Characteristics Table 8.
How does the 30 kV ESD rating impact system-level protection design?
The 30 kV IEC 61000-4-2 contact discharge rating allows HPZR-C7V0-Q to absorb full ESD events at the board level without downstream protection components. This eliminates secondary TVS diodes on 7 V rails in infotainment and gateway modules, reducing BOM cost and layout complexity.
Can HPZR-C7V0-Q replace older 7 V Zeners like BZX84-C7V0 in existing automotive designs?
No direct replacement: HPZR-C7V0-Q has higher power (5.5 W vs. 0.3 W), different package (CFP3 vs. SOT23), and AEC-Q101 qualification. Migration requires PCB footprint redesign, thermal validation, and requalification - but delivers superior surge immunity and long-term reliability in new designs.
