Product details
Overview
HPZR-C17X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at 15.6–17.2 V nominal working voltage (IZ = 1 mA), with 4.1 W DC power dissipation at Tsp = 75 °C and 30 kV ESD rating per IEC 61000-4-2 (contact discharge). It serves as a stable reference or clamp in power supply feedback paths, overvoltage protection circuits, and sensor biasing networks.
For engineers reviewing the HPZR-C17X datasheet, HPZR-C17X pinout, HPZR-C17X application, or HPZR-C17X equivalent, key selection criteria include its ±5 % tolerance, 14 Ω dynamic impedance at 20 mA, 0.1 µA max reverse leakage at VR = 14 V, and thermal resistance of 18 K/W junction-to-solder-point - critical for compact PCB designs requiring robust transient suppression and stable DC regulation.
Technical Context
This device operates as a silicon planar Zener diode optimized for stable reverse-bias voltage regulation under low-current conditions (IZ = 1 mA for HPZR-C17X). Its breakdown mechanism is predominantly avalanche-dominated above ~6 V, delivering tight voltage control with minimal temperature drift across -55 °C to +150 °C ambient range.
Thermal performance is defined by junction-to-solder-point resistance (Rth(j-sp) = 18 K/W), enabling reliable 4.1 W dissipation when mounted on FR4 PCB with zero-lead-length measurement condition. The cathode-marked SOD123W footprint supports automated reflow and wave soldering per IPC-7351B standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Working Voltage (VZ) | 15.6 V min to 17.2 V max at IZ = 1 mA - defines precise regulation window for mid-range supply rails |
| Total Power Dissipation (Ptot) | 4100 mW @ Tsp = 75 °C (zero lead length) - enables high-power clamping without heatsink in space-constrained layouts |
| Differential Resistance (RZ) | 14 Ω max at IZ = 20 mA - ensures minimal output voltage shift under load transients |
| Reverse Leakage (IR) | 0.1 µA max at VR = 14 V - guarantees low quiescent current in battery-powered or ultra-low-power systems |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - provides robust handling immunity during assembly and field operation |
| Thermal Resistance (Rth(j-sp)) | 18 K/W - allows direct thermal coupling to PCB copper for efficient heat extraction without thermal vias |
| Junction Temperature (Tj) | 150 °C max - supports operation in industrial environments with elevated ambient temperatures |
Pinout & Package
HPZR-C17X 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. Mounting requires 1 cm² cathode pad on single-sided tin-plated FR4 for rated 4.1 W dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marking bar identifies this pin - connects to regulated node or ground reference in shunt configuration |
| 2 | Anode (A) | Positive terminal; ties to unregulated input or voltage source - reverse-biased during normal regulation operation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Density | 4.1 W dissipation in 2.6 mm × 1.7 mm footprint - reduces board area vs. legacy DO-214AC packages |
| Precision Voltage Tolerance | ±5 % nominal VZ - eliminates need for post-production trimming in cost-sensitive consumer power supplies |
| Low Dynamic Impedance | 14 Ω at 20 mA - maintains regulation stability under fast load steps in feedback loops |
| ESD-Hardened Construction | 30 kV contact discharge rating - prevents failure during handling and system-level ESD events |
| Wide Operating Range | -55 °C to +150 °C ambient - suitable for under-hood automotive modules and industrial motor drives |
Applications
| Power Supply Feedback Regulation | Overvoltage Clamp Protection |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C16 | 16 V nominal, 250 mW Ptot, SOT23 package, RZ = 40 Ω | Limited to low-power signal-level clamping; unsuitable for >100 mA regulation loads | Choose only for space-constrained logic-level protection where power dissipation < 0.3 W |
| 1N4744A | 15 V nominal, 1 W Ptot, DO-41 through-hole, RZ = 14 Ω | Requires PCB real estate and manual assembly; lacks ESD hardening (no IEC 61000-4-2 rating) | Select when legacy through-hole compatibility is mandatory and ESD immunity is not required |
Compared with BZX84-C16 and 1N4744A, HPZR-C17X delivers 4× higher power density than the SOT23 part and 4.1× greater dissipation than the DO-41 device - enabling compact, high-reliability shunt regulation in modern SMT power management without thermal derating penalties.

FAQ
What is the maximum continuous reverse current (IZ) at which HPZR-C17X maintains specified VZ tolerance?
HPZR-C17X is characterized at IZ = 1 mA for VZ specification (15.6–17.2 V), with differential resistance tested at 20 mA. Operation up to 400 mA forward current is permitted per limiting values, but reverse regulation remains stable and within ±5 % tolerance from 0.1 mA to 100 mA, verified across -55 °C to +125 °C.
Can HPZR-C17X replace standard 1N47xx series Zeners in existing PCB layouts?
No - HPZR-C17X uses CFP3 (SOD123W) package (2.6 mm × 1.7 mm), while 1N47xx parts use DO-41 (4.5 mm × 2.5 mm). Footprint, thermal pad requirements, and soldering profiles differ significantly. A redesign using Nexperia's recommended 1.1 mm × 1.1 mm cathode land is required for full 4.1 W capability.
How does the 30 kV ESD rating translate to system-level protection?
The 30 kV rating applies to contact discharge per IEC 61000-4-2 at the cathode solder point, meaning the diode survives direct ESD strikes during handling and board assembly. It does not provide system-level surge immunity - external TVS or RC filtering remains necessary for I/O port protection against cable discharge events.
Is HPZR-C17X suitable for automotive applications?
HPZR-C17X is not AEC-Q200 qualified and lacks automotive-specific testing (e.g., vibration, extended temperature cycling). While it operates from -55 °C to +150 °C and meets industrial reliability standards, Nexperia explicitly states non-automotive qualification in its legal disclaimers - use requires customer validation for each target vehicle subsystem.
