Product details

Overview

HPZR-C10X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision DC voltage clamping and regulation at 10 V nominal working voltage (V_Z = 9.44–10.40 V @ I_Z = 1 mA), with 4.1 W total power dissipation at T_sp = 75 °C and 30 kV ESD rating per IEC 61000-4-2 (contact discharge), used in industrial power supply rail protection and low-current reference stabilization circuits.

For engineers reviewing the HPZR-C10X datasheet, HPZR-C10X pinout, HPZR-C10X application, or HPZR-C10X equivalent, this page delivers verified thermal resistance (R_th(j-sp) = 18 K/W), differential impedance (R_Z = 18.02 Ω @ I_Z = 20 mA), reverse leakage (I_R ≤ 10 μA @ V_R = 8.5 V), forward voltage (V_F ≤ 1 V @ I_F = 100 mA), and non-repetitive surge capability (P_ZSM = 800 W, t_p ≤ 100 µs).

Technical Context

This device operates as a two-terminal, silicon planar Zener diode optimized for stable voltage regulation under transient overvoltage conditions. Its 10 V nominal breakdown voltage is specified at I_Z = 1 mA with ±5 % tolerance, and it maintains low dynamic impedance (18.02 Ω) to ensure tight regulation across load variations.

Thermal design centers on junction-to-solder-point conduction (R_th(j-sp) = 18 K/W), enabling efficient heat transfer through the cathode tab to PCB copper. The CFP3 package supports zero-lead-length DC power dissipation up to 4.1 W at solder point temperature ≤ 75 °C, validated per IEC 60134 absolute maximum ratings.

Key Specifications

Parameter	Value and Actual Design Meaning
V_Z (Nominal)	10 V - precise DC voltage reference point at I_Z = 1 mA, with min/max range 9.44–10.40 V
P_tot	4100 mW - maximum continuous DC power dissipation at T_sp = 75 °C, measured at zero lead length
R_Z	18.02 Ω - low differential resistance ensures minimal output voltage shift under 20 mA current variation
I_R @ V_R	≤10 μA @ 8.5 V - ultra-low reverse leakage preserves regulation accuracy in high-impedance bias networks
V_F	≤1 V @ 100 mA - low forward drop enables bidirectional clamping and fast turn-on during overvoltage events
ESD Rating	30 kV - withstands contact discharge per IEC 61000-4-2, protecting downstream circuitry without external TVS staging
P_ZSM	800 W - non-repetitive peak reverse power handling for 100 µs square-wave transients (e.g., EFT bursts)

Pinout & Package

HPZR-C10X 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 cathode tab soldering to ≥1 cm² copper pad on FR4 PCB.

Pin/Terminal	Circuit Role	Design Meaning
1 (K)	Cathode	Primary heat path and voltage reference node; must be soldered to large copper area for thermal management
2 (A)	Anode	Current return path; electrically and thermally isolated from cathode tab in layout

Key Features

Feature	Design Value
High surge power handling	800 W non-repetitive peak reverse power (t_p ≤ 100 µs), enabling robust EFT/ESD immunity without derating
Precision Zener voltage	10 V nominal with ±5 % tolerance and 18.02 Ω dynamic impedance, supporting stable 1 mA reference biasing
Low thermal resistance	R_th(j-sp) = 18 K/W - minimizes junction temperature rise during sustained 4.1 W operation via cathode tab conduction
ESD-hardened construction	30 kV contact discharge rating per IEC 61000-4-2, eliminating need for upstream ESD protection in many applications
Compact SMD footprint	CFP3 (SOD123W) package fits high-density layouts while maintaining 4.1 W power capability - 3× smaller than TO-220 equivalents

Applications

Industrial Power Rail Protection

Low-Power Reference Voltage Source

Use Scenario: Clamping 12 V DC input rails against load-dump transients and switching noise in PLC I/O modules.

IC Role / Device Role / Timing Role: Two-terminal shunt regulator absorbing surge energy and holding rail voltage within ±0.5 V of 10 V.

Use Value: Eliminates need for discrete RC snubbers or secondary TVS arrays due to integrated 800 W surge rating and 30 kV ESD hardening.

Use Scenario: Providing stable 10 V reference for 12-bit ADC biasing in battery-powered sensor nodes.

IC Role / Device Role / Timing Role: Precision Zener element delivering regulated voltage at 1 mA quiescent current with <10 μA leakage.

Use Value: Enables <±0.5 LSB reference error over temperature (−40 °C to +125 °C) without trimming, reducing BOM count.

Automated Test Equipment (ATE) Signal Conditioning

LED Driver Current Sense Clamp

Use Scenario: Protecting analog front-end inputs from overvoltage during probe misconnection in benchtop DMMs.

IC Role / Device Role / Timing Role: Fast-acting clamp limiting input to 10.4 V max, activated within nanoseconds of overvoltage onset.

Use Value: Prevents op-amp saturation and latch-up with sub-100 ns response, preserving measurement integrity during fault events.

Use Scenario: Stabilizing feedback voltage in constant-current LED drivers using high-side sense resistors.

IC Role / Device Role / Timing Role: Shunt regulator maintaining fixed 10 V reference across sense resistor to set LED current accurately.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener voltage regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BZX84-C10	300 mW P_tot, SOT23 package, R_Z = 20 Ω, V_Z = 9.4–10.6 V	Limited to low-power signal-level clamping; cannot sustain >150 mW continuous dissipation	Select only for space-constrained logic-level protection where surge immunity and thermal margin are not required.
SMBJ10A	600 W P_ZSM, 10 V standoff, unidirectional TVS, R_Z > 100 Ω	Designed for transient suppression only; lacks precision regulation and stable DC clamping behavior	Choose when primary need is ESD/EFT burst absorption rather than stable DC voltage reference or biasing.

Compared with BZX84-C10 and SMBJ10A, HPZR-C10X uniquely combines 4.1 W DC power handling, 18 Ω dynamic impedance, and 30 kV ESD rating in a single 2.6 mm × 1.7 mm footprint-enabling both precision regulation and robust transient protection without cascaded components.

FAQ

What is the maximum continuous DC power dissipation for HPZR-C10X at 25 °C ambient?

At T_amb ≤ 25 °C on an FR4 PCB with single-sided 1 cm² cathode copper pad, HPZR-C10X sustains 962 mW continuous DC power dissipation. This value rises to 4100 mW when measured at solder point temperature T_sp = 75 °C with zero lead length, per IEC 60134 limiting values.

How does the 30 kV ESD rating impact system-level protection design?

The 30 kV contact discharge rating (IEC 61000-4-2) means HPZR-C10X can absorb full-system ESD events directly at the board edge without upstream protection. This eliminates discrete ESD diodes in many designs, reduces parasitic capacitance on sensitive lines, and simplifies layout-verified by ten non-repetitive pulses applied at the cathode solder point.

Can HPZR-C10X replace traditional 1N4740A in existing designs?

No direct drop-in replacement: HPZR-C10X is a surface-mount CFP3 device (2.6 mm × 1.7 mm), while 1N4740A is through-hole DO-41 (4.5 mm × 2.5 mm). Electrically, HPZR-C10X offers tighter V_Z tolerance (±5 % vs. ±5 %), lower R_Z (18.02 Ω vs. ~20 Ω), and higher P_tot (4.1 W vs. 1 W), but requires PCB redesign and reflow process validation.

What is the significance of R_th(j-sp) = 18 K/W in thermal management?

R_th(j-sp) = 18 K/W quantifies thermal resistance from silicon junction to solder point-critical for predicting junction temperature rise under DC load. With 4.1 W dissipation, ΔT = 73.8 °C above solder point temperature; thus, keeping T_sp ≤ 75 °C ensures T_j ≤ 148.8 °C, safely below the 150 °C absolute maximum rating.
