Product details
Overview
HPZR-C3V6X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision low-current regulation at nominal 3.6 V with ±5 % tolerance, 4.1 W DC power dissipation at Tsp = 75 °C, and 30 kV ESD rating per IEC 61000-4-2 (contact discharge), used in voltage reference and overvoltage protection circuits in industrial power supplies.
For engineers reviewing the HPZR-C3V6X datasheet, HPZR-C3V6X pinout, HPZR-C3V6X application, or HPZR-C3V6X equivalent, key selection criteria include its 3.4–3.8 V working voltage range at IZ = 100 mA, 16 μA max reverse current, 8 Ω differential resistance, and thermal resistance of 18 K/W junction-to-solder-point - critical for compact PCB designs requiring stable regulation under thermal stress.
Technical Context
This device operates as a two-terminal silicon Zener diode with sharp reverse breakdown characteristics, optimized for stable DC voltage regulation in low-current (<400 mA forward, ≤100 mA Zener test current) applications. Its design targets minimal voltage drift across temperature and high surge immunity via robust junction construction.
The CFP3 package enables low-profile surface mounting with direct cathode tab thermal coupling to PCB copper, supporting 4.1 W total power dissipation only when soldered to ≥1 cm² cathode pad on FR4 - confirming its role as a thermally managed discrete regulator, not a general-purpose signal diode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 3.6 V (min 3.4 V, max 3.8 V at IZ = 100 mA) - defines precise regulation point for 3.3 V rail stabilization |
| Max Reverse Current | 16 μA at VR = 1.0 V - ensures negligible leakage in standby mode |
| Differential Resistance | 8 Ω at IZ = 100 mA - provides tight voltage regulation under load variation |
| Total Power Dissipation | 4100 mW at Tsp = 75 °C (zero lead length) - requires thermal pad for full rating |
| ESD Rating | 30 kV per IEC 61000-4-2 contact discharge - protects against handling and system-level ESD events |
| Forward Voltage | 1.0 V at IF = 100 mA - limits conduction loss during forward bias conditions |
| Junction Temperature | 150 °C max - sets upper thermal limit for continuous operation |
Pinout & Package
Package: CFP3 (SOD123W), plastic surface-mount package, 2.6 mm × 1.7 mm × 1.0 mm body, flat lead, low-profile; cathode marked by bar on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main heat path: soldered tab directly couples junction to PCB copper for thermal management |
| 2 | Anode (A) | Current entry point during reverse-bias regulation; electrically isolated from thermal pad |
Key Features
| Feature | Design Value |
|---|---|
| High power density | 4.1 W dissipation in 2.6 mm × 1.7 mm footprint - enables space-constrained regulation without external heatsink |
| Tight voltage tolerance | ±5 % nominal 3.6 V - reduces need for post-regulation trimming in precision analog references |
| Robust ESD immunity | 30 kV contact discharge rating - eliminates need for external TVS in many industrial I/O protection schemes |
| Low differential resistance | 8 Ω at 100 mA - maintains <0.1 V output shift across 10–100 mA load range |
| Thermally optimized package | Rth(j-sp) = 18 K/W - allows direct thermal coupling to PCB for predictable derating curves |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C3V6 | 300 mW rating, SOT23 package, RZ = 90 Ω at 5 mA | Lower power, higher impedance - suitable only for signal-level biasing, not power regulation | Select when board space is constrained and load current <5 mA; avoid for >100 mA applications |
| MMSZ4685 | 500 mW rating, SOD-123 package, VZ = 3.6 V ±5 %, RZ = 15 Ω at 10 mA | Higher RZ and lower Ptot - cannot sustain 4.1 W or support 100 mA Zener current continuously | Choose for cost-sensitive consumer designs where thermal margin is ample and peak power <0.5 W |
Compared with BZX84-C3V6 and MMSZ4685, HPZR-C3V6X delivers 8× higher power capability and 10× lower dynamic impedance at rated current - making it uniquely suited for industrial regulation where thermal stability and load regulation error are design-critical.

FAQ
What is the maximum continuous Zener current for HPZR-C3V6X at 25 °C ambient?
The device supports up to 100 mA Zener test current per datasheet characterization, but continuous operation depends on thermal design. At Tamb = 25 °C on FR4 with 1 cm² cathode pad, Ptot = 962 mW permits ~267 mA average Zener current (962 mW ÷ 3.6 V), assuming no additional forward-bias losses.
Can HPZR-C3V6X replace a standard 1N4728A in existing designs?
No - the 1N4728A is DO-41 packaged (1 W, 1000 mW), while HPZR-C3V6X is SMD CFP3 with 4.1 W rating and different thermal interface requirements. Direct replacement requires redesigning the PCB pad for thermal coupling and verifying surge current compatibility, as HPZR-C3V6X has higher IFSM (50 A vs. 1N4728A's 25 A).
Does HPZR-C3V6X meet automotive AEC-Q200 requirements?
No - the datasheet states "Non-automotive qualified products" and does not list AEC-Q200 qualification. It is intended for industrial, computing, and consumer applications; automotive use requires explicit Nexperia automotive-grade variants like the PZU series.
How does the 30 kV ESD rating translate to real-world board-level protection?
The 30 kV rating applies to single-contact discharge at the cathode solder point per IEC 61000-4-2. In practice, this means the diode can safely clamp ESD events up to Level 4 (30 kV contact) without parametric shift or failure - provided layout minimizes trace inductance between the protected node and cathode pad.
