Product details
Overview
HPZR-C13X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision DC voltage clamping and regulation at 13 V nominal working voltage (12.2–13.5 V), with ±5 % tolerance, 4.1 W total power dissipation at Tsp = 75 °C, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge). It serves as a stable shunt reference in low-current power supply rails and overvoltage protection circuits.
For engineers reviewing the HPZR-C13X datasheet, HPZR-C13X pinout, HPZR-C13X application, or HPZR-C13X equivalent, key selection criteria include its 13 V nominal Zener voltage at IZ = 1 mA, 2.5 µA max reverse current at VR = 11 V, 11 Ω differential resistance at IZ = 20 mA, and thermal resistance of 130 K/W on FR4 PCB with 1 cm² cathode pad - critical for thermal design in compact SMD power regulation.
Technical Context
This device operates as a silicon planar Zener diode with controlled avalanche breakdown, optimized for stable voltage regulation under low-current conditions (IZ = 1 mA). Its VZ specification is guaranteed across temperature (Tj = 25 °C), with junction temperature rated up to 150 °C and storage range from −65 °C to +150 °C.
The CFP3 package enables low-profile mounting with minimal thermal resistance to solder point (Rth(j-sp) = 18 K/W), supporting high peak pulse power handling (PZSM = 800 W, tp ≤ 100 µs) while maintaining DC dissipation limits of 4.1 W at zero-lead-length measurement condition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 13 V (min 12.2 V, max 13.5 V at IZ = 1 mA); defines precise clamping threshold for 12 V rail stabilization |
| Reverse Current | ≤ 2.5 µA at VR = 11 V; ensures low leakage in standby regulation mode |
| Differential Resistance | 11 Ω at IZ = 20 mA; determines regulation stiffness and output impedance in shunt configuration |
| Total Power Dissipation | 4100 mW at Tsp = 75 °C (zero lead length); sets maximum continuous DC power handling on thermally optimized PCB |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge; enables robustness against human-body ESD events without external protection |
| Forward Voltage | ≤ 1 V at IF = 100 mA; supports bidirectional surge suppression when used with series resistor |
| Junction Temperature Limit | 150 °C; constrains maximum ambient operating temperature based on PCB thermal design |
Pinout & Package
HPZR-C13X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, low-profile profile optimized for automated reflow assembly and thermal conduction via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marking bar identifies this terminal; primary heat path to PCB copper pad |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes Zener bias path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| High power dissipation | 4.1 W at Tsp = 75 °C enables use in higher-current shunt regulators without heatsinking |
| Tight voltage tolerance | ±5 % nominal Zener voltage improves accuracy in reference and feedback applications |
| Ultra-high ESD immunity | 30 kV contact discharge rating eliminates need for discrete ESD protection in many I/O rail designs |
| Low thermal resistance | 130 K/W (junction-to-ambient, FR4, 1 cm² cathode pad) supports reliable operation in space-constrained layouts |
| Standard SOD123W footprint | Compatible with industry-standard reflow footprints (e.g., 1.1 mm × 1.4 mm solder land) for seamless PCB integration |
Applications
| Industrial Sensor Power Rail | USB Port Overvoltage Clamp |

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 Ptot, SOT23 package, RZ = 30 Ω at IZ = 5 mA | Limited to low-power signal-level clamping; unsuitable for >100 mA shunt loads | Select only for space-constrained signal rails where power dissipation < 0.3 W |
| 1N4742A | 1 W Ptot, DO-41 through-hole, VZ = 12 V ±5 %, RZ = 9 Ω | Requires manual assembly; lacks ESD rating and SMD thermal performance | Choose only for legacy through-hole designs or prototyping where reflow compatibility is not required |
Compared with BZX84-C13 and 1N4742A, HPZR-C13X delivers 13.7× higher power capability than BZX84-C13 and 4.1× higher than 1N4742A, while offering superior ESD immunity and SMD thermal management - making it uniquely suited for production-grade, high-reliability 13 V regulation in modern PCBs.

FAQ
What is the recommended PCB layout for optimal thermal performance of HPZR-C13X?
Use a 1 cm² tin-plated copper pad connected to the cathode (Pin 1) on a single-sided FR4 board. Maintain ≥0.3 mm clearance from adjacent traces, avoid thermal reliefs on the cathode pad, and follow Nexperia's SOD123W reflow footprint (1.1 mm × 1.4 mm solder land, 0.1 mm stencil thickness) to ensure full thermal conduction and 130 K/W Rth(j-a).
Can HPZR-C13X be used in series or parallel configurations?
Series connection is not recommended due to mismatched Zener voltage tolerances and thermal coupling effects. Parallel use is discouraged unless matched units are selected and derated - the device lacks built-in current-sharing features, and uneven thermal distribution may cause premature failure of one unit under load.
Does HPZR-C13X meet automotive qualification standards?
No. HPZR-C13X is not AEC-Q200 qualified and is not tested to automotive temperature, vibration, or lifetime requirements. It is intended for industrial, computing, and consumer applications. For automotive use, consult Nexperia's AUTOMOTIVE-grade Zener portfolio (e.g., PZUxx series) with full AEC-Q200 certification.
How does the 30 kV ESD rating translate to real-world system protection?
The 30 kV rating (IEC 61000-4-2 contact discharge) means HPZR-C13X can absorb a single 30 kV ESD event at its cathode without parametric shift or failure - verified across ten non-repetitive pulses. This provides intrinsic protection for downstream ICs in handheld or field-serviceable equipment, reducing or eliminating need for external TVS devices on protected rails.
