Product details
Overview
HPZR-C15-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 14.4 V to 15.9 V nominal Zener voltage at IZ = 1 mA, with ≤0.1 µA reverse leakage, 13 Ω dynamic impedance, and 5.5 W DC power dissipation at Tsp = 75 °C - used in engine control unit (ECU) supply rail stabilization.
For engineers reviewing the HPZR-C15-QX datasheet, HPZR-C15-QX pinout, HPZR-C15-QX application, or HPZR-C15-QX equivalent, this device supports AEC-Q101-compliant automotive designs requiring robust ESD immunity (30 kV contact), low-profile SMD mounting, and stable regulation under transient load conditions.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (~±5 %) across its 14.4–15.9 V range. Its thermal design centers on junction-to-solder-point resistance of 18 K/W, enabling efficient heat transfer from the cathode tab to PCB copper when mounted on FR4 with 1 cm² cathode pad.
The device sustains non-repetitive peak reverse power up to 800 W (tp ≤ 100 µs) and handles IFSM = 50 A (8.3 ms half-sine), making it suitable for surge suppression in 12 V automotive systems where load dump transients exceed ISO 7637-2 Pulse 5a.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 14.4 V to 15.9 V at IZ = 1 mA - defines precise clamping threshold for 12 V system overvoltage protection |
| Reverse Leakage IR | ≤0.1 µA at VR = 13 V - ensures negligible standby current in always-on vehicle modules |
| Differential Resistance RZ | 13 Ω at IZ = 20 mA - maintains tight voltage regulation under dynamic load steps |
| Total Power Dissipation Ptot | 5500 mW at Tsp = 75 °C (zero lead length) - enables high continuous power handling without heatsink |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against human-body ESD events during assembly and service |
| Junction Temperature Tj | −55 °C to +175 °C - supports operation in under-hood environments including transmission control units |
| Package | CFP3 (SOD123W), 2.6 mm × 1.7 mm × 1.0 mm - ultra-low profile SMD footprint compatible with automated reflow assembly |
Pinout & Package
HPZR-C15-QX uses a 2-terminal CFP3 (SOD123W) surface-mount plastic package with cathode-side marking bar. Thermal performance relies on direct soldering of the cathode tab to a 1 cm² copper pad on FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main heat path and voltage reference node; marked by bar; connects to regulated rail ground or return |
| 2 | Anode (A) | Input side for reverse-biased operation; ties to unregulated supply or transient source |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD stress per discrete semiconductor standard |
| High surge capability | Withstands 50 A non-repetitive forward surge (8.3 ms) and 800 W reverse pulse (100 µs), supporting ISO 7637-2 compliance |
| Low-profile thermal package | CFP3 outline provides 18 K/W junction-to-solder-point thermal resistance - 3× better than standard SOD-123 |
| Tight Zener tolerance | ±5 % VZ spread enables accurate voltage clamping without post-production trimming in safety-critical ECUs |
| High ESD immunity | 30 kV contact discharge rating eliminates need for external ESD protection in CAN/LIN node power inputs |
Applications
| Engine Control Unit (ECU) Power Rail Clamping | Body Control Module (BCM) Voltage Reference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C15 | 300 mW Ptot, SOT23 package, ±5 % VZ, RZ = 30 Ω | Limited to low-power logic rails; unsuitable for automotive surge suppression | Select only for non-automotive, low-current (<5 mA) biasing applications |
| PZUX15 | 1.3 W Ptot, SOD-323, VZ = 14.7 V ±5 %, RZ = 25 Ω | Lower surge rating (IFSM = 2.5 A); not AEC-Q101 qualified | Acceptable for industrial sensors but lacks automotive qualification and thermal margin |
Compared with BZX84-C15 and PZUX15, HPZR-C15-QX delivers 18× higher power dissipation, 1/2 the dynamic impedance, and full AEC-Q101 validation - making it the sole choice for under-hood automotive voltage regulation where thermal stability and transient immunity are mandatory.

FAQ
What is the maximum continuous power dissipation for HPZR-C15-QX at 75 °C solder point temperature?
The HPZR-C15-QX delivers 5500 mW DC power dissipation at Tsp = 75 °C with zero lead length measurement condition. This value assumes direct cathode tab soldering to a 1 cm² copper pad on FR4 PCB - achieving this rating requires strict adherence to the recommended footprint in Figure 11 of the datasheet.
Does HPZR-C15-QX meet automotive qualification standards?
Yes, HPZR-C15-QX is fully qualified to AEC-Q101 for discrete semiconductors, covering stress tests including high-temperature reverse bias, temperature cycling, and ESD per IEC 61000-4-2. It is explicitly recommended for automotive applications in the official Nexperia product data sheet Rev. 6.
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD-123?
The CFP3 package features an extended cathode tab that increases copper contact area, reducing Rth(j-sp) to 18 K/W - versus ~45 K/W for standard SOD-123. This 2.5× lower thermal resistance allows 5.5 W operation at Tsp = 75 °C, whereas standard SOD-123 parts are typically limited to ≤1.5 W under identical conditions.
What is the reverse leakage current specification for HPZR-C15-QX at 13 V?
HPZR-C15-QX guarantees ≤0.1 µA reverse leakage current at VR = 13 V and Tj = 25 °C, as specified in Table 12 of the datasheet. This ultra-low leakage supports always-on automotive modules such as telematics and alarm systems where quiescent current must remain below 1 µA.
