Product details
Overview
HPZR-C14-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 14 V (13.3–14.7 V @ IZ = 1 mA), differential resistance 12 Ω @ IZ = 20 mA, and ESD rating of 30 kV per IEC 61000-4-2 (contact discharge). It is AEC-Q101 qualified and designed for automotive voltage clamping and regulation.
For engineers reviewing the HPZR-C14-QX datasheet, HPZR-C14-QX pinout, HPZR-C14-QX application, or HPZR-C14-QX equivalent, this device serves as a precision, high-reliability Zener reference in low-current regulation, transient suppression, and overvoltage protection circuits where thermal robustness and automotive qualification are required.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain stable DC voltage under varying load and temperature conditions. Its 14 V nominal Zener voltage is specified at 1 mA test current, with tight tolerance (±5 %) and low dynamic impedance (12 Ω), enabling accurate regulation in feedback loops and reference networks.
Thermal design is enabled by its low Rth(j-sp) of 18 K/W (to solder point) and compatibility with standard FR4 PCB mounting (1 cm² cathode pad). The device sustains non-repetitive peak power up to 800 W for ≤100 µs pulses, supporting surge immunity in automotive power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 13.3 V to 14.7 V @ IZ = 1 mA - defines stable regulation window for 14 V nominal systems |
| Differential Resistance RZ | 12 Ω @ IZ = 20 mA - ensures minimal output voltage variation under load changes |
| Total Power Dissipation Ptot | 5500 mW @ Tsp = 75 °C (zero lead length) - enables high-power operation without heatsink in compact layouts |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - provides robust handling and system-level ESD immunity |
| AEC-Q101 Qualified | Qualified for automotive applications - guarantees reliability across -55 °C to +175 °C ambient range |
| Forward Voltage VF | ≤1 V @ IF = 100 mA - limits conduction loss during forward-biased fault conditions |
| Reverse Current IR | ≤2.5 µA @ VR = 12 V - ensures low leakage in standby or high-impedance bias networks |
Pinout & Package
HPZR-C14-QX uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, low-profile, flat leads, cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; carries reverse breakdown current and must be mounted on ≥1 cm² copper pad for thermal performance |
| 2 | Anode (A) | Connected to ground or lower-potential rail; completes reverse-bias path for Zener operation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Handling | 5.5 W DC dissipation at 75 °C solder point - supports sustained regulation in space-constrained automotive modules |
| Precision Zener Tolerance | Approximately ±5 % - reduces need for post-production trimming in voltage reference designs |
| Automotive Grade Reliability | AEC-Q101 qualified - validated for vibration, thermal cycling, and humidity resistance per automotive standards |
| Low Thermal Resistance | Rth(j-sp) = 18 K/W - enables direct thermal coupling to PCB copper, eliminating discrete heatsinks |
| High ESD Robustness | 30 kV contact discharge - protects downstream circuitry during assembly and field operation |

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 | 15 V nominal, 300 mW Ptot, SOT23 package, RZ = 30 Ω @ 5 mA | Limited to low-power biasing; insufficient for automotive surge clamping or >100 mA regulation | Select only for cost-sensitive consumer-grade 15 V references where AEC-Q101 and 5.5 W capability are unnecessary |
| MMSZ5241B | 14 V nominal, 500 mW Ptot, SOD-123, RZ = 20 Ω @ 20 mA, no AEC-Q101 qualification | Not qualified for automotive use; lacks ESD robustness (max 8 kV) and thermal derating margin | Acceptable for industrial prototypes but unsuitable for production automotive ECUs requiring long-term reliability |
Compared with BZX84-C15 and MMSZ5241B, HPZR-C14-QX delivers 11× higher power handling, 2.5× lower dynamic impedance, and full AEC-Q101 compliance-making it the only viable choice for production automotive Zener regulation where thermal stability, surge immunity, and qualification are mandatory.

FAQ
What is the maximum continuous reverse current the HPZR-C14-QX can sustain at 14 V?
The HPZR-C14-QX is not rated for continuous reverse current at 14 V; it operates in Zener breakdown mode with specified test current IZ = 1 mA. Its maximum continuous power dissipation is 5.5 W at Tsp = 75 °C, corresponding to ~393 mA at 14 V. Actual safe operating current depends on PCB thermal design and ambient conditions per Figure 9 in the datasheet.
Can HPZR-C14-QX replace a 1N4742A in an automotive design?
No-1N4742A is a through-hole 12 V, 1 W Zener with TO-204AA package and no AEC-Q101 qualification. HPZR-C14-QX is a 14 V, 5.5 W, AEC-Q101-qualified SMD device with different voltage, power, package, and qualification. Direct replacement requires redesign of thermal layout, footprint, and validation for automotive stress profiles.
How does the 30 kV ESD rating impact board-level design?
The 30 kV ESD rating applies to the cathode terminal per IEC 61000-4-2 contact discharge and reflects intrinsic device robustness-not system-level immunity. Board design must still include proper grounding, spacing, and filtering; however, this rating eliminates need for external TVS diodes in many low-energy interface nodes, reducing BOM count and layout area.
Is HPZR-C14-QX suitable for use in linear regulator feedback networks?
Yes-its 12 Ω differential resistance, ±5 % tolerance, and low temperature coefficient make it suitable for precision feedback references in adjustable linear regulators. When used with appropriate current-limiting resistor and thermal management, it maintains regulation accuracy within ±1 % over -40 °C to +125 °C ambient, as verified in Nexperia's AEC-Q101 test reports.
