Product details
Overview
HPZR-C23-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision voltage clamping and regulation in automotive-grade circuits. It delivers 22.2 V to 24.5 V nominal Zener voltage at IZ = 1 mA, supports 5.5 W DC power dissipation at Tsp = 75 °C, and withstands 30 kV ESD per IEC 61000-4-2 (contact discharge), enabling robust operation in engine control units and body electronics.
For engineers reviewing the HPZR-C23-QX datasheet, HPZR-C23-QX pinout, HPZR-C23-QX application, or HPZR-C23-QX equivalent, this device serves as a high-reliability, AEC-Q101-qualified Zener for overvoltage protection, reference stabilization, and low-current regulation where thermal performance and ESD immunity are critical selection criteria.
Technical Context
This Zener diode operates in reverse breakdown mode with tightly controlled VZ tolerance (~±5 %) across its 22.2–24.5 V range and exhibits low differential resistance of 35.51 Ω at IZ = 20 mA, ensuring stable regulation under dynamic load conditions. Its junction-to-solder-point thermal resistance is 18 K/W, enabling efficient heat transfer to PCB copper pads.
The device complies with AEC-Q101 stress testing for discrete semiconductors and meets IEC 61000-4-2 Level 4 ESD requirements (>30 kV contact). It supports non-repetitive peak power dissipation up to 800 W for tp ≤ 100 µs, making it suitable for transient suppression in 12 V/24 V automotive subsystems.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C24 | 24 V ±5 % VZ, 300 mW Ptot, SOT23 package, Rth(j-a) = 400 K/W | Limited to low-power signal-level clamping; unsuitable for >100 mA continuous regulation | Select when space-constrained PCB layout prioritizes footprint over power handling |
| PZM24NB2 | 24 V ±5 % VZ, 400 mW Ptot, SOD-123 package, RZ = 50 Ω at IZ = 5 mA | Higher RZ and lower surge capability (500 W peak); not AEC-Q101 qualified | Choose only for non-automotive industrial applications with relaxed reliability requirements |
Compared with BZX84-C24 and PZM24NB2, HPZR-C23-QX delivers 18× higher DC power capability, 2.2× lower thermal resistance, and certified automotive qualification-making it the sole option for thermally demanding, safety-critical 24 V rail regulation.

FAQ
What is the maximum continuous forward current rating for HPZR-C23-QX?
The HPZR-C23-QX is a Zener diode intended for reverse-bias operation; its absolute maximum forward current (IF) is 400 mA per datasheet limiting values. However, forward conduction is not its functional mode-designs must maintain reverse bias to achieve specified VZ regulation and power dissipation characteristics.
Can HPZR-C23-QX be used in parallel for higher power handling?
No-Zener diodes exhibit negative temperature coefficient and parameter spread; paralleling HPZR-C23-QX units causes current imbalance and thermal runaway. For higher power, select a single higher-rated device such as HPZR-C24-QX or implement active regulation with external pass elements.
Is the cathode pad electrically isolated from the internal die substrate?
Yes-the cathode terminal (Pin 1) is the sole electrical connection to the Zener junction; the exposed cathode metal pad serves only as a thermal conduction path and is not internally shorted to any other potential. PCB layout must maintain isolation unless explicitly grounded per system design.
Does HPZR-C23-QX require derating when mounted on 2-layer FR4 versus ceramic substrate?
Yes-total power dissipation drops from 5500 mW at Tsp = 75 °C on ceramic (Al2O3) to 1154 mW on standard FR4 with 1 cm² cathode pad. Thermal design must follow Table 8 Rth(j-a) values: 70 K/W on ceramic vs. 130 K/W on FR4, directly impacting safe operating area.
