Detailed Description

High-voltage N-channel superjunction MOSFET from the CoolMOS CE family. Rated for 500 V class operation with a low RDS(on) class around 1.4 Ω, optimized for cost-effective, energy-efficient consumer power supplies. Typical DPAK footprint for easy layout and thermal management. Suited for flyback and other hard-switching topologies where low switching loss and robust avalanche behavior are needed

Key Features

500 V class drain-source voltage for wide input AC applications

Low RDS(on) class approx 1.4 Ω at VGS 10 V for lower conduction loss

Superjunction technology for lower switching loss versus planar MOSFETs

Fast switching with low gate charge for higher efficiency at light and full load

High dv/dt ruggedness and avalanche capability for robust operation

Standard DPAK TO-252 footprint for compact designs

Pb-free, RoHS compliant, halogen free

ESD protected gate and robust body diode behavior

Production date code family 14+ available in stock depending on lot

Key Advantages

Higher efficiency and lower heat in compact adapters and LED drivers

Cost-optimized CoolMOS CE platform reduces total BOM cost

Drop-in DPAK footprint accelerates design and qualification

Better EMI profile due to lower switching energy

Reliable under line surges and startup stress thanks to avalanche ruggedness

Broad ecosystem and long-term availability from a Tier-1 supplier

Packaging

Device package type DPAK also known as TO-252-3 SMD

Molded epoxy package with copper leadframe and large drain tab for heat spreading

Typical body size about 6.5 x 6.1 mm low profile around 2.3 mm height refer to datasheet for exact dimensions

Pin configuration Pin 1 Gate Pin 2 Drain tied to thermal tab Pin 3 Source confirm with datasheet land pattern

Thermal performance DPAK offers low junction-to-case thermal resistance in the typical 3 to 5 K W range and junction-to-ambient depending on PCB copper area and airflow see datasheet for test conditions and curves
