Product details
Overview
HPZR-C26-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 26 V (±5 % tolerance), 0.1 µA reverse current at VR = 24.4 V, and 22 Ω differential resistance at IZ = 20 mA - used for precision overvoltage clamping and voltage reference in automotive body control modules.
For engineers reviewing the HPZR-C26-QX datasheet, HPZR-C26-QX pinout, HPZR-C26-QX application, or HPZR-C26-QX equivalent, this device supports stable regulation under transient surge conditions (800 W non-repetitive peak power), meets AEC-Q101 qualification, and delivers low thermal resistance (18 K/W junction-to-solder-point) for thermally constrained PCB layouts.
Technical Context
This Zener diode operates in reverse breakdown mode to maintain a stable DC reference voltage across its terminals. Its 26 V nominal Zener voltage is specified at IZ = 20 mA, with differential resistance of 22 Ω ensuring tight regulation under load variation. The device exhibits 0.1 µA reverse leakage at 24.4 V, enabling low-power standby compliance.
Thermal design relies on direct cathode tab conduction: Rth(j-sp) = 18 K/W to solder point enables efficient heat transfer to PCB copper, while ESD robustness reaches 30 kV per IEC 61000-4-2 (contact discharge), supporting harsh automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 26 V ±5 % - defines precise clamping threshold for 24 V automotive systems |
| Total Power Dissipation | 5500 mW @ Tsp = 75 °C - enables sustained operation without heatsink in compact layouts |
| Differential Resistance | 22 Ω @ IZ = 20 mA - ensures <1 % output deviation across ±10 mA load current swing |
| Reverse Leakage Current | 0.1 µA @ VR = 24.4 V - minimizes quiescent power loss in always-on circuits |
| Non-repetitive Peak Power | 800 W @ tp ≤ 100 µs - suppresses ESD and load-dump transients without failure |
| ESD Rating | 30 kV contact discharge (IEC 61000-4-2) - eliminates need for external TVS in many infotainment interfaces |
| Junction Temperature Limit | 175 °C - supports under-hood deployment in engine control units |
Pinout & Package
HPZR-C26-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 optimized via exposed cathode tab soldered directly to PCB copper.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary heat path: soldered tab conducts >90 % of thermal load to PCB; polarity indicator for correct orientation |
| 2 | Anode (A) | Low-inductance return path; connects to ground or low-impedance reference node during clamping |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use including temperature cycling, humidity, and mechanical shock per discrete semiconductor standard |
| Zero-lead-length power rating | 5.5 W derating defined at solder point (not ambient), enabling accurate thermal modeling without lead parasitics |
| Low-profile SMD package | 1.0 mm max height allows placement beneath connectors or shields in space-constrained ECUs |
| High ESD immunity | 30 kV contact discharge rating reduces risk of field failure in assembly and end-use handling |
| Stable Zener voltage tolerance | ±5 % ensures predictable clamping across production lots without post-manufacture binning |

FAQ
What is the maximum continuous power dissipation for HPZR-C26-QX at 75 °C solder point temperature?
The maximum continuous power dissipation is 5500 mW (5.5 W) when measured at zero lead length with solder point temperature maintained at 75 °C - this value is validated per IEC 60134 limiting values and reflects direct thermal conduction through the cathode tab to PCB copper.
How does the 22 Ω differential resistance impact regulation accuracy in a 24 V system?
At 22 Ω, a ±10 mA change in Zener current produces only ±0.22 V shift in regulated voltage - enabling stable 26 V reference for sensitive analog circuits like audio amplifiers or ADC references without additional buffering.
Is HPZR-C26-QX compatible with standard SOD123W reflow footprints?
Yes - it uses the industry-standard CFP3 (SOD123W) outline with 2.6 mm × 1.7 mm body and 1.0 mm height, matching IPC-7351B SOD123W footprint recommendations, including 1.1 mm pad width and 2.1 mm pad length for optimal solder joint reliability.
Why is the reverse leakage current specified at 24.4 V instead of the nominal 26 V?
24.4 V corresponds to the maximum rated reverse voltage (VR) - the highest voltage at which leakage is guaranteed ≤0.1 µA; operating above this risks exponential leakage increase and thermal runaway, so design must ensure VR remains below this limit during all transients.
