Product details
Overview
HPZR-C17-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 15.6 V to 17.2 V nominal working voltage at IZ = 1 mA, supports ≤5.5 W DC power dissipation at Tsp = 75 °C, and features 30 kV ESD rating per IEC 61000-4-2 (contact discharge), qualified to AEC-Q101.
For engineers reviewing the HPZR-C17-QX datasheet, HPZR-C17-QX pinout, HPZR-C17-QX application, or HPZR-C17-QX equivalent, this device is selected for robust overvoltage protection in 12 V/24 V automotive subsystems where thermal stability, low-profile SMD mounting, and high surge immunity are critical.
Technical Context
This Zener diode operates in reverse-bias breakdown mode with tightly controlled VZ tolerance (~±5 %) and low differential resistance (27.56 Ω at IZ = 20 mA). Its thermal design targets junction-to-solder-point resistance of 18 K/W, enabling reliable operation up to 175 °C junction temperature under pulsed or continuous DC stress.
It sustains non-repetitive peak reverse power up to 800 W for tp ≤ 100 µs and handles IFSM = 50 A (8.3 ms half-sine), making it suitable for transient suppression in alternator-regulated circuits and load-dump scenarios.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal VZ | 17 V (15.6–17.2 V range at IZ = 1 mA; enables stable reference in 12 V automotive systems) |
| Ptot @ Tsp = 75 °C | 5500 mW (DC-rated power dissipation with zero-lead-length measurement; supports high ambient thermal loads) |
| RZ | 27.56 Ω (differential resistance at IZ = 20 mA; ensures low dynamic impedance for precise regulation) |
| VF @ IF = 100 mA | ≤1 V (forward voltage drop; minimizes conduction loss during forward bias events) |
| ESD Rating | 30 kV (IEC 61000-4-2 contact discharge; protects against human-body and assembly-line ESD events) |
| IR @ VR | 0.1 µA max (reverse leakage at rated VR; guarantees low standby current in always-on circuits) |
| Tj max | 175 °C (maximum junction temperature; supports under-hood deployment without derating) |
Pinout & Package
HPZR-C17-QX uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile optimized for thermal transfer via cathode pad. The marking bar identifies the cathode terminal.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; soldered to 1 cm² copper pad for optimal thermal dissipation and ESD path |
| 2 | Anode (A) | Ground or low-impedance return path; establishes reverse-bias polarity for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard |
| High surge capability | 800 W non-repetitive peak power (tp ≤ 100 µs) enables protection against ISO 7637-2 pulse 5a load dump transients |
| Low-profile thermal package | CFP3 footprint with Rth(j-sp) = 18 K/W allows direct heat sinking to PCB copper without heatsinks in space-constrained modules |
| Tight VZ tolerance | ±5 % nominal tolerance ensures predictable clamping threshold across production lots and temperature ranges |
| Low leakage current | 0.1 µA max reverse current at rated VR reduces quiescent power drain in battery-sensitive applications |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | 16 V nominal VZ, 250 mW Ptot, SOT23 package, RZ = 40 Ω | Limited to low-power signal-level clamping; unsuitable for automotive power rail surge handling | Select only for non-automotive, low-current (<10 mA) reference use where thermal margin is not required. |
| 1N4744A | 15 V nominal VZ, 1 W Ptot, DO-41 through-hole, RZ = 14 Ω | Through-hole mounting incompatible with automated SMT lines; lacks AEC-Q101 qualification and ESD robustness | Use only in legacy industrial designs where board real estate and automotive compliance are not constraints. |

FAQ
What is the maximum continuous power dissipation for HPZR-C17-QX at 75 °C solder point temperature?
The maximum continuous DC power dissipation is 5500 mW when measured at zero lead length and Tsp = 75 °C, as specified in Table 5 and Fig. 9 of the datasheet. This value assumes direct thermal coupling to a 1 cm² cathode copper pad on FR4 PCB.
Does HPZR-C17-QX meet automotive qualification standards?
Yes, HPZR-C17-QX is fully qualified to AEC-Q101 for discrete semiconductors, including stress tests for temperature cycling, high-temperature reverse bias, and ESD per IEC 61000-4-2. It is explicitly recommended for automotive applications in Section 11 of the datasheet.
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD-123?
The CFP3 variant features wider, flattened leads and optimized internal die attach, reducing Rth(j-sp) to 18 K/W versus ~30 K/W for standard SOD-123. This enables 5.5 W DC dissipation at Tsp = 75 °C-more than double typical SOD-123 capability-without external heatsinking.
What is the reverse leakage current specification for HPZR-C17-QX at its rated reverse voltage?
The maximum reverse leakage current is 0.1 µA at VR = 14 V, as listed in Table 12 for HPZR-C17-Q. This ultra-low leakage ensures minimal standby power draw in always-on automotive subsystems such as telematics and gateway modules.
