Product details
Overview
HPZR-C60X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, rated for 4.1 W DC power dissipation at 75 °C solder point temperature, with nominal working voltage 60 V (56.7–62.7 V at IZ = 1 mA), differential resistance ≤ 51 Ω, and ESD rating of 30 kV per IEC 61000-4-2 contact discharge - used for precision low-current regulation in industrial power rails and sensor biasing.
For engineers reviewing the HPZR-C60X datasheet, HPZR-C60X pinout, HPZR-C60X application, or HPZR-C60X equivalent, this page delivers verified thermal performance (Rth(j-sp) = 18 K/W), pulse robustness (PZSM = 800 W, tp ≤ 100 µs), junction temperature limit (150 °C), and mounting-specific power derating curves - critical for overvoltage clamp design in space-constrained SMD layouts.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias voltage regulation under low-current conditions (IZ = 1 mA). Its 60 V nominal Zener voltage is specified with ±5 % tolerance and exhibits low dynamic impedance (≤ 51 Ω) to maintain regulation accuracy across load transients.
Thermal design centers on junction-to-solder-point conduction: Rth(j-sp) = 18 K/W enables high DC power handling when mounted on a 1 cm² cathode pad on FR4 PCB, while non-repetitive surge capability (800 W, 100 µs square wave) supports transient suppression in power supply input stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VZ (Nominal) | 60 V - precise regulation point at IZ = 1 mA, with min/max range 56.7–62.7 V |
| Ptot @ Tsp = 75 °C | 4100 mW - maximum continuous DC power dissipation measured at zero lead length |
| RZ | ≤ 51 Ω - differential resistance ensures <1.5 V output variation across ±10 mA current change |
| VESD | 30 kV - IEC 61000-4-2 contact discharge rating confirms robustness against handling ESD events |
| IFSM | 50 A - non-repetitive peak forward surge current (8.3 ms half-sine) supports inrush immunity |
| Tj max | 150 °C - absolute maximum junction temperature defines thermal safety margin in sealed enclosures |
| Rth(j-sp) | 18 K/W - thermal resistance to solder point enables direct thermal coupling to PCB copper pour |
Pinout & Package
HPZR-C60X uses the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, low-profile design optimized for automated reflow assembly and thermal conduction via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; marked by bar on top surface; primary thermal path to PCB copper pad |
| 2 | Anode (A) | Positive terminal; electrically and thermally less critical; connects to regulated output reference |
Key Features
| Feature | Design Value |
|---|---|
| High DC power capability | 4.1 W at Tsp = 75 °C - enables compact regulation without heatsinks in 12–48 V industrial supplies |
| Low dynamic impedance | ≤ 51 Ω at IZ = 20 mA - maintains tight voltage stability during microcontroller I/O rail fluctuations |
| ESD-hardened construction | 30 kV contact discharge rating - eliminates need for external ESD protection in sensor interface circuits |
| Thermally optimized package | Rth(j-sp) = 18 K/W - allows >90 % of heat to transfer directly from junction to solder point on PCB |
| Wide Zener voltage range | 60 V nominal with ±5 % tolerance - supports legacy 48 V telecom and PoE+ auxiliary rail compliance |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C62 | 62 V nominal, 300 mW Ptot, SOT23 package, RZ = 100 Ω | Lower power and higher impedance - suitable only for signal-level bias, not power rail clamping | Select when board space is critical and power dissipation <300 mW; avoid for >1 mA regulation loads |
| 1N4749A | 62 V nominal, 1 W Ptot, DO-41 through-hole, RZ = 60 Ω | Larger footprint, lower thermal efficiency (Rth(j-a) ≈ 70 K/W), no ESD rating | Choose for prototyping or legacy through-hole designs where reflow compatibility is not required |
Compared with BZX84-C62 and 1N4749A, HPZR-C60X delivers 13.7× higher DC power handling than the SOT23 part and 4.1× more than the DO-41 device, while its 30 kV ESD rating and 18 K/W junction-to-pad thermal path enable reliable operation in dense, automated SMT assemblies without derating penalties.

FAQ
What is the maximum continuous current HPZR-C60X can regulate at 60 V?
At 60 V Zener voltage and Tsp = 75 °C, HPZR-C60X supports up to 68.3 mA continuous DC current (4100 mW ÷ 60 V), assuming ideal thermal coupling to a 1 cm² cathode pad on FR4 PCB. Derating applies above 75 °C solder point temperature per Figure 9 in the datasheet.
Does HPZR-C60X require a series current-limiting resistor in regulation mode?
Yes - like all Zener diodes, HPZR-C60X requires an external series resistor to set operating current within its specified IZ range (1 mA typical). The resistor value is calculated as R = (VIN − 60 V) / IZ, where IZ must remain between 0.25 mA and 68.3 mA to ensure regulation and avoid thermal runaway.
How does the CFP3 (SOD123W) package improve thermal performance over standard SOD123?
The CFP3 variant features an extended cathode tab that increases copper contact area on PCB, reducing Rth(j-sp) to 18 K/W versus ~40 K/W for standard SOD123. This allows 4.1 W dissipation at Tsp = 75 °C - more than 4× the power handling of conventional Zeners in same footprint.
Can HPZR-C60X be used for bidirectional transient suppression?
No - HPZR-C60X is a unidirectional Zener diode. It conducts only in reverse breakdown (cathode positive relative to anode) and has no specified forward surge rating beyond IFSM = 50 A. For bidirectional protection, a TVS diode such as PESD5V0S1BA should be used instead.
