Product details
Overview
HPZR-C30X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) surface-mount package, designed for precision DC voltage regulation and transient suppression in space-constrained power rails. It delivers 4.1 W total power dissipation at Tsp = 75 °C, features ±5 % tolerance, operates at nominal 30 V working voltage (VZ = 28.9–31.9 V @ IZ = 1 mA), and withstands 30 kV ESD per IEC 61000-4-2 contact discharge - used in industrial power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the HPZR-C30X datasheet, HPZR-C30X pinout, HPZR-C30X application, or HPZR-C30X equivalent, this page provides verified thermal resistance (Rth(j-sp) = 18 K/W), differential impedance (RZ = 26 Ω @ IZ = 20 mA), non-repetitive peak power (800 W), forward voltage (≤1 V @ 100 mA), and mounting pad thermal design guidance for FR4 PCBs with 1 cm² cathode pad.
Technical Context
This device functions as a two-terminal, silicon planar Zener diode operating in reverse breakdown mode to maintain stable reference voltage under varying load and temperature conditions. Its CFP3 package enables low-profile mounting with optimized thermal path via the cathode tab, supporting DC power dissipation up to 4.1 W when soldered to a 1 cm² copper pad on FR4.
It complies with IEC 61000-4-2 Level 4 ESD immunity (>30 kV contact), supports surge handling up to 50 A IFSM (8.3 ms half-sine), and exhibits tight VZ tolerance (±5 %) across its 30 V nominal rating - enabling reliable use in closed-loop regulation where reference stability directly impacts output accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Working Voltage) | 28.9 V to 31.9 V @ IZ = 1 mA - defines regulated output voltage range for feedback or clamping applications |
| Ptot (Total Power Dissipation) | 4100 mW @ Tsp = 75 °C (zero lead length) - maximum continuous DC power handling under thermal pad cooling |
| RZ (Differential Resistance) | 26 Ω @ IZ = 20 mA - low dynamic impedance ensures minimal output voltage drift under load variation |
| VF (Forward Voltage) | ≤1 V @ IF = 100 mA - limits conduction loss during forward-biased fault conditions |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to solder point, critical for calculating junction temperature rise with pad layout |
| IR (Reverse Current) | 0.1 μA @ VR = 24.3 V - ultra-low leakage preserves regulation accuracy in high-impedance bias networks |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against electrostatic damage during handling and board assembly |
Pinout & Package
HPZR-C30X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat lead profile, cathode marked by a bar on the top surface. Thermal performance relies on direct soldering of the cathode tab to a 1 cm² copper pad on FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main thermal and electrical return path; must be connected to large copper area for rated 4.1 W dissipation |
| 2 | Anode (A) | Input/reference node connection; reverse-biased during regulation; low-inductance trace recommended |
Key Features
| Feature | Design Value |
|---|---|
| High Power Density | 4.1 W in SOD123W footprint - enables compact voltage regulation without external heatsinks in 12–48 V systems |
| Tight Zener Tolerance | ±5 % VZ - reduces need for post-production trimming in precision reference designs |
| Low Differential Impedance | 26 Ω @ 20 mA - maintains <±0.5 % output voltage deviation across 1–20 mA load current range |
| ESD-Robust Construction | 30 kV IEC 61000-4-2 contact discharge - eliminates need for external TVS in many front-end protection schemes |
| Thermally Optimized Cathode Tab | Rth(j-sp) = 18 K/W - allows accurate junction temperature prediction using solder point temperature measurement |
Applications
| Industrial Power Supply Feedback | Overvoltage Clamp for Microcontroller I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30 | 300 mW Ptot, SOT23 package, RZ = 40 Ω @ 5 mA, ±5 % VZ | Limited to low-power biasing; unsuitable for >100 mA regulation or surge clamping | Select when board space is constrained and power <0.3 W; avoid for thermal-critical or high-current regulation |
| MMSZ5256ET1G | 500 mW Ptot, SOD123 package, RZ = 35 Ω @ 20 mA, ±5 % VZ | Lower thermal capability (Rth(j-a) ≈ 400 K/W vs. 18 K/W to solder point); no cathode-tab thermal path | Choose for cost-sensitive consumer designs with ambient-limited dissipation; not for sustained 4.1 W operation |
Compared with BZX84-C30 and MMSZ5256ET1G, HPZR-C30X uniquely supports 4.1 W continuous dissipation via its cathode-tab thermal interface, offers 18 K/W Rth(j-sp), and delivers 26 Ω RZ - making it the only option among the three viable for high-stability, high-power Zener regulation in industrial power electronics.

FAQ
What is the maximum continuous current HPZR-C30X can regulate at 30 V?
At 30 V nominal Zener voltage, HPZR-C30X supports up to ~137 mA continuous DC current (4100 mW ÷ 30 V) when mounted on a 1 cm² FR4 copper pad at Tsp = 75 °C. Derating is required above 75 °C solder point temperature per Fig. 9 in the datasheet, and peak current must stay below 50 A for 8.3 ms surges.
Can HPZR-C30X replace a 1N4749A in existing designs?
No - the 1N4749A is a 30 V, 1 W through-hole Zener (DO-41). HPZR-C30X has higher power (4.1 W), smaller SMD footprint (CFP3), lower RZ (26 Ω vs. ~35 Ω), and different thermal path. Direct replacement requires PCB redesign for SOD123W footprint and thermal pad layout; electrical compatibility exists but thermal validation is mandatory.
How does the cathode tab improve thermal performance over standard SOD123 devices?
The cathode tab in HPZR-C30X provides a dedicated low-thermal-resistance path (Rth(j-sp) = 18 K/W) from junction to solder point, unlike standard SOD123 anodes/cathodes that rely on trace conduction. This enables 4.1 W dissipation - over 4× higher than typical SOD123 Zeners - when soldered to a 1 cm² copper pad, verified per Table 5 and Fig. 9.
Is HPZR-C30X automotive qualified?
No - HPZR-C30X is not automotive qualified. The datasheet explicitly states "Non-automotive qualified products" and excludes AEC-Q101 qualification. It is intended for industrial, computing, and consumer applications. Use in automotive systems requires full customer validation and carries no Nexperia warranty for automotive stress conditions or lifetime requirements.
