Product details
Overview
HPZR-C13-QX from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 13 V nominal working voltage at IZ = 1 mA, with ±5 % tolerance, 2.5 µA max reverse current, and 11 Ω differential resistance at IZ = 20 mA - designed for precision voltage clamping and regulation in automotive power rails.
For engineers reviewing the HPZR-C13-QX datasheet, HPZR-C13-QX pinout, HPZR-C13-QX application, or HPZR-C13-QX equivalent, this device supports stable low-current regulation under transient surges up to 800 W peak, operates across −55 °C to +175 °C ambient, and meets AEC-Q101 qualification for under-hood electronics.
Technical Context
This Zener diode operates in reverse-bias breakdown mode to maintain a stable reference voltage across its cathode–anode terminals. Its 13 V nominal Zener voltage is specified at 1 mA test current, with tight 12.2–13.5 V min/max range and low dynamic impedance (11 Ω), enabling accurate regulation under varying load conditions.
Thermal design is enabled by low junction-to-solder-point thermal resistance (18 K/W) and DC power dissipation of 5.5 W at Tsp = 75 °C (zero lead length). It withstands non-repetitive 50 A surge current (8.3 ms half-sine) and 30 kV ESD per IEC 61000-4-2 contact discharge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 12.2 V to 13.5 V at IZ = 1 mA - defines precise clamping threshold for 12 V system protection |
| Reverse Current IR | ≤ 2.5 µA at VR = 10.4 V - ensures minimal leakage during standby operation |
| Differential Resistance RZ | 11 Ω at IZ = 20 mA - maintains voltage stability against load transients |
| Total Power Dissipation Ptot | 5500 mW at Tsp = 75 °C (zero lead length) - enables high-power surge handling without heatsink |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against human-body ESD events in assembly and field use |
| Junction Temperature | −55 °C to +175 °C - supports operation in engine compartment and other high-temp automotive zones |
| Non-repetitive Peak Power | 800 W for tp ≤ 100 µs - suppresses fast transients like load dump spikes |
Pinout & Package
HPZR-C13-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 to 1 cm² copper pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to regulated output node; primary heat path to PCB copper pad |
| 2 (A) | Anode | Connected to ground or lower-potential rail; completes reverse-bias conduction path |
Key Features

| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control units and body electronics |
| 5.5 W DC power rating @ Tsp = 75 °C | Enables robust overvoltage protection without external heatsinking in space-constrained modules |
| 13 V Zener voltage with ±5 % tolerance | Matches 12 V nominal vehicle electrical systems while accommodating battery voltage variation |
| 30 kV ESD immunity (IEC 61000-4-2) | Eliminates need for additional ESD protection circuitry in infotainment and sensor interface designs |
| Low RZ = 11 Ω at 20 mA | Minimizes output voltage deviation during dynamic load steps in microcontroller supply rails |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C13 | 300 mW rating, SOT23 package, RZ = 30 Ω, no AEC-Q101 qualification | Limited to low-power consumer circuits; unsuitable for automotive surge environments | Select only for cost-sensitive non-automotive prototypes where 5.5 W surge capability is unnecessary |
| MMSZ5242B | 500 mW rating, SOD-123 package, VZ = 12.05–13.25 V, RZ = 25 Ω, no 30 kV ESD rating | Lower surge margin and ESD immunity; requires supplemental TVS for automotive use | Choose when board space allows dual-device protection scheme and thermal budget permits derating |

FAQ
What is the maximum continuous power dissipation for HPZR-C13-QX at 25 °C ambient?
At Tamb ≤ 25 °C on an FR4 PCB with single-sided 1 cm² cathode copper pad, HPZR-C13-QX supports 1154 mW continuous DC power dissipation. This value drops to 5500 mW only when measured at solder point temperature (Tsp) of 75 °C with zero lead length - a condition requiring direct thermal coupling to PCB copper.
Does HPZR-C13-QX require external current-limiting resistors in typical Zener regulator configurations?
Yes - like all Zener diodes, HPZR-C13-QX must be used with a series current-limiting resistor to set operating current within its specified IZ range (1 mA typical). The resistor value is calculated using (VIN − VZ) / IZ, ensuring power dissipation in both resistor and diode remains within absolute maximum ratings.
How does the 30 kV ESD rating apply to real-world PCB layout?
The 30 kV rating applies specifically to contact discharge at the cathode solder point per IEC 61000-4-2. To achieve this performance, the cathode pad must be directly connected to a ≥1 cm² copper pour with minimum 35 µm copper thickness and no isolation gaps - any routing trace or narrow neck degrades ESD robustness significantly.
Can HPZR-C13-QX replace standard 1N4742A Zener diodes in existing designs?
No - HPZR-C13-QX is not a drop-in replacement for 1N4742A due to fundamental differences: 1N4742A is through-hole (DO-41), rated 1 W, and unqualified for automotive use. HPZR-C13-QX is SMD (CFP3), rated 5.5 W, AEC-Q101 qualified, and has different thermal mounting requirements - redesign of footprint, copper area, and surge margin analysis is mandatory.
