ASM65R280E Silicon N Channel MOSFET Ideal for Flyback and Forward Topologies in Power Supplies
Product Overview
The ASA65R280E, ASD65R280E, and ASM65R280E are N-Channel Silicon MOSFETs designed for high-efficiency power applications. These enhancement-mode MOSFETs feature low drain-source on-resistance (RDS(ON) = 240m typ.) and easy gate switching control. They are ideal for single-ended flyback or two-transistor forward topologies in applications such as PC power supplies, PD adaptors, LCD & PDP TVs, and LED lighting.
