Product details
Overview
HPZR-C5V1-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 5.5 W total power dissipation at Tsp = 75 °C, with nominal working voltage 5.1 V (±5 % tolerance), differential resistance ≤6.0 Ω at IZ = 100 mA, and ESD rating of 30 kV per IEC 61000-4-2 (contact discharge). It serves as a precision voltage reference or overvoltage clamp in automotive power rails.
For engineers reviewing the HPZR-C5V1-QX datasheet, HPZR-C5V1-QX pinout, HPZR-C5V1-QX application, or HPZR-C5V1-QX equivalent, key selection criteria include its 4.8–5.4 V Zener voltage range at 100 mA, low 0.75 µA max reverse current at VR, thermal resistance of 18 K/W junction-to-solder-point, AEC-Q101 qualification, and SOD123W footprint compatibility with standard reflow profiles.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable DC voltage regulation under transient and steady-state conditions. Its design targets automotive-grade reliability with junction temperature up to 175 °C and non-repetitive peak power dissipation of 800 W for pulses ≤100 µs.
The CFP3 package enables low thermal resistance (Rth(j-sp) = 18 K/W) via direct cathode tab soldering, supporting high-current surge handling without derating. The ±5 % VZ tolerance and <6.0 Ω dynamic impedance ensure tight regulation across production lots and temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ @ IZ = 100 mA | 4.80–5.40 V - defines regulated output voltage window under standard test current |
| RZ @ IZ = 100 mA | ≤6.0 Ω - ensures minimal voltage deviation during load current changes |
| IR @ VR | ≤0.75 µA - guarantees low leakage in standby or high-impedance bias networks |
| Ptot @ Tsp = 75 °C | 5500 mW - supports continuous operation in thermally constrained automotive PCB layouts |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - eliminates need for external ESD protection in infotainment and body control modules |
| Tj Max | 175 °C - enables placement near heat-generating components like power MOSFETs or DC-DC converters |
| Rth(j-sp) | 18 K/W - allows efficient heat transfer directly from die to solder pad, critical for pulse power handling |
Pinout & Package
HPZR-C5V1-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.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C5V1 | 300 mW rating, SOT23 package, RZ = 60 Ω, no AEC-Q101 qualification | Limited to low-power consumer electronics; unsuitable for automotive surge environments | Select only for cost-sensitive non-automotive prototypes with <50 mA load |

FAQ
What is the maximum continuous power dissipation for HPZR-C5V1-QX at 75 °C solder point temperature?
The maximum continuous power dissipation is 5500 mW when measured at zero lead length with solder point temperature held at 75 °C. This value assumes direct thermal coupling of the cathode tab to a 1 cm² copper pad on FR4 PCB, and must be derated linearly above 75 °C per the thermal curve in Figure 9 of the datasheet.
Does HPZR-C5V1-QX require external current-limiting resistors in typical regulation circuits?
Yes-like all Zener diodes, HPZR-C5V1-QX requires a series current-limiting resistor to set operating current within its specified 100 mA test condition and prevent thermal runaway. The resistor value is calculated using (VIN − VZ) / IZ, where IZ is selected between 10 mA and 400 mA based on regulation stability and power budget.
How does the 30 kV ESD rating impact board-level protection design?
The 30 kV contact discharge rating means HPZR-C5V1-QX can absorb ESD events without damage or parameter shift, eliminating the need for upstream TVS diodes in many automotive sub-circuits. However, it does not replace system-level I/O protection; it functions as a local clamp at the regulated node, reducing layout complexity and BOM count.
Can HPZR-C5V1-QX be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficient and mismatched VZ tolerances, causing current hogging and thermal instability when paralleled. For >5.5 W requirements, use a single higher-rated device or switch to active regulation; do not parallel HPZR-C5V1-QX units without individual ballast resistors and thermal derating.
