Product details
Overview
HPZR-C5V6X from Nexperia is a high-power Zener voltage regulator diode in CFP3 (SOD123W) package, designed for precision DC voltage clamping and regulation at 5.6 V nominal working voltage with ±5 % tolerance. It delivers 4.1 W total power dissipation at Tsp = 75 °C, supports 600 µA max reverse current at IZ = 10 mA, and features 3.3 Ω typical differential resistance - used in overvoltage protection circuits for industrial power supplies and sensor interface rails.
For engineers reviewing the HPZR-C5V6X datasheet, HPZR-C5V6X pinout, HPZR-C5V6X application, or HPZR-C5V6X equivalent, key selection criteria include its 5.2–6.0 V Zener voltage range, 800 W non-repetitive peak power capability, ESD robustness (30 kV contact discharge), and thermal performance on FR4 PCBs with 1 cm² cathode pad.
Technical Context
This device operates as a two-terminal, silicon planar Zener diode optimized for stable reverse-bias regulation under transient and steady-state conditions. Its design targets low-impedance voltage reference and clamping functions where tight voltage tolerance, high surge immunity, and compact SMD mounting are required.
It exhibits a 3.3 Ω differential resistance at IZ = 20 mA and maintains ≤600 µA reverse leakage at rated VZ, enabling accurate regulation in low-current bias networks and feedback paths. Thermal resistance from junction to solder point is 18 K/W, supporting reliable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 5.2–6.0 V at IZ = 10 mA - defines precise clamping threshold for 5 V rail protection |
| Differential Resistance (RZ) | 3.3 Ω at IZ = 20 mA - ensures minimal output voltage shift under load variation |
| Reverse Current (IR) | ≤600 µA at VR = 5.2 V - guarantees low quiescent power loss in standby regulation |
| Total Power Dissipation (Ptot) | 4100 mW at Tsp = 75 °C (zero lead length) - enables high-power transient absorption without heatsink |
| Non-repetitive Peak Power (PZSM) | 800 W for tp ≤ 100 µs - sustains ESD and surge events per IEC 61000-4-2 |
| ESD Rating | 30 kV per IEC 61000-4-2 (contact discharge) - eliminates need for external ESD protection in many interfaces |
| Forward Voltage (VF) | ≤1.0 V at IF = 100 mA - allows use as low-loss series diode in dual-role protection circuits |
Pinout & Package
HPZR-C5V6X 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 assembly and thermal conduction via cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to regulated output node; marked by bar on top surface; primary heat path to PCB copper pad |
| 2 | Anode (A) | Connected to ground or lower-potential reference; completes reverse-bias conduction path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| High Power Handling | 4.1 W DC dissipation at 75 °C solder point - supports sustained clamping in industrial 24 V systems |
| Tight Voltage Tolerance | ±5 % nominal 5.6 V - reduces need for post-regulation trimming in precision analog front-ends |
| Ultra-Low Differential Resistance | 3.3 Ω at 20 mA - maintains <±20 mV output deviation across 10 mA load steps |
| ESD-Hardened Construction | 30 kV contact discharge rating - qualifies for direct placement on exposed I/O lines without guard rings |
| Thermally Optimized Package | 18 K/W Rth(j-sp) - enables >90 % of rated power dissipation on standard FR4 with 1 cm² cathode pad |

FAQ
What is the maximum continuous power dissipation for HPZR-C5V6X on a standard FR4 PCB?
HPZR-C5V6X delivers 962 mW total power dissipation when mounted on an FR4 PCB with single-sided copper and a 1 cm² cathode pad at Tamb ≤ 25 °C. Derating begins above 25 °C ambient, reaching 4100 mW at Tsp = 75 °C with zero lead length measurement condition.
How does the 30 kV ESD rating impact layout requirements?
The 30 kV IEC 61000-4-2 contact discharge rating is achieved through internal process hardening - no additional PCB guard rings or spacing beyond standard 0.2 mm creepage are required. The cathode tab serves as the primary ESD current path, so direct connection to a solid ground plane enhances performance.
Can HPZR-C5V6X be used in series or parallel configurations?
HPZR-C5V6X is not recommended for parallel operation due to VZ mismatch causing current imbalance. In series, up to three devices may be stacked for higher clamping voltage, but derating of total power by 20 % per added device is required to maintain thermal safety margins.
What is the significance of the "X" suffix in HPZR-C5V6X?
The "X" suffix denotes tape-and-reel packaging per standard Nexperia ordering convention: HPZR-C5V6X indicates 10,000 units per reel in CFP3 (SOD123W) package, compatible with J-STD-020 moisture sensitivity level 1 and standard SMT pick-and-place equipment.
