Product details
Overview
HPZR-C5V6-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 5.6 V nominal working voltage at IZ = 10 mA, ≤600 µA reverse current, 3.3 Ω differential resistance at IZ = 20 mA, and 5.5 W total DC power dissipation at Tsp = 75 °C - enabling robust overvoltage protection in engine control units and ADAS sensor power supplies.
For engineers reviewing the HPZR-C5V6-QX datasheet, HPZR-C5V6-QX pinout, HPZR-C5V6-QX application, or HPZR-C5V6-QX equivalent, key selection criteria include its AEC-Q101 qualification, 30 kV IEC 61000-4-2 ESD rating, 50 A non-repetitive peak forward current, and thermal resistance of 18 K/W (junction-to-solder point), critical for under-hood thermal reliability and transient surge resilience.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode with sharp reverse breakdown characteristics optimized for stable DC voltage reference and transient suppression. Its design targets regulated biasing of analog sensors and gate drivers where ±5 % tolerance and low dynamic impedance are essential.
The CFP3 package enables high thermal efficiency via direct cathode tab soldering to PCB copper, supporting 5.5 W DC dissipation at 75 °C solder point temperature - significantly exceeding standard SOD-123 ratings. Junction temperature is rated up to 175 °C, aligning with automotive under-hood ambient requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 5.6 V at IZ = 10 mA - defines precise clamping threshold for 5 V rail protection |
| Reverse Current (IR) | ≤600 µA at VR = 5.2 V - ensures low leakage during standby operation |
| Differential Resistance (RZ) | 3.3 Ω at IZ = 20 mA - maintains tight regulation under load transients |
| Total Power Dissipation (Ptot) | 5500 mW @ Tsp = 75 °C (zero lead length) - enables high-power surge handling without heatsink |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against human-body ESD events in assembly and field use |
| Junction Temperature (Tj) | −55 °C to +175 °C - supports operation in extreme automotive environments including engine compartments |
| Thermal Resistance (Rth(j-sp)) | 18 K/W - allows efficient heat transfer from junction to solder point on FR4 PCB |
Pinout & Package
HPZR-C5V6-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. Mounting pad for cathode requires 1 cm² tin-plated copper on FR4 for rated power dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; primary heat path to PCB copper via exposed tab |
| 2 (A) | Anode | Connected to ground or return path; carries full surge current during clamping events |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability across temperature cycling, humidity, and mechanical stress tests |
| 5.5 W DC power rating @ Tsp = 75 °C | Enables single-device overvoltage protection in 12 V/24 V systems without derating or parallel devices |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for external ESD protection in infotainment and body control modules |
| ±5 % VZ tolerance | Ensures predictable clamping behavior across production lots for functional safety compliance |
| Low RZ = 3.3 Ω | Minimizes output voltage shift under dynamic load changes in sensor bias networks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V6 | 300 mW Ptot, SOT23 package, RZ = 40 Ω, no AEC-Q101 qualification | Limited to low-power consumer logic rails; unsuitable for automotive under-hood thermal or surge demands | Select only for cost-sensitive non-automotive applications with <100 mA steady-state current |
| PZM5.6NB,115 | 500 mW Ptot, SOD323 package, VZ = 5.6 V ±5 %, RZ = 10 Ω, AEC-Q101 qualified | Lower power rating restricts use to signal-level clamping; insufficient for power rail protection | Prefer for space-constrained board-level ESD protection on 5 V data lines, not main power domains |
Compared with BZX84-C5V6 and PZM5.6NB, HPZR-C5V6-QX uniquely combines AEC-Q101 qualification, 5.5 W power handling, and 3.3 Ω dynamic impedance - making it the only option among the three capable of regulating 12 V automotive power rails while surviving load dump and ESD events without derating.

FAQ
What is the maximum continuous forward current rating for HPZR-C5V6-QX?
The absolute maximum forward current (IF) is 400 mA per the limiting values table. However, this rating applies only under defined thermal conditions - sustained operation above 100 mA requires careful PCB copper layout to maintain Tj ≤ 175 °C, as VF reaches 1 V at 100 mA and increases with current.
Does HPZR-C5V6-QX require a heatsink for 5.5 W operation?
No external heatsink is required. The 5.5 W rating is achieved with zero lead length and direct cathode tab soldering to a 1 cm² tin-plated copper pad on FR4 PCB. Thermal resistance to solder point is 18 K/W, enabling full power dissipation through the PCB alone when layout guidelines are followed.
How does the 30 kV ESD rating relate to real-world automotive assembly?
The 30 kV rating per IEC 61000-4-2 contact discharge reflects worst-case human-body ESD exposure during manual handling. It ensures the device survives electrostatic discharge at the cathode solder point - the most vulnerable location - without parameter shift or failure, eliminating post-assembly retest needs in Tier 1 harness and module assembly lines.
Can HPZR-C5V6-QX be used in parallel for higher power handling?
Parallel operation is not recommended due to mismatched Zener voltage tolerances (±5 %) and thermal coupling effects. Even minor VZ differences cause current hogging, leading to premature thermal runaway. For >5.5 W requirements, select a higher-voltage variant or implement active regulation instead.
