IR Debuts IRF6216/IRF6217 HEXFET Power MOSFETs

April 18, 2002 by Jeff Shepard

International Rectifier Corp. (IR, El Segundo, CA) introduced the IRF6216 and IRF6217 p-channel, HEXFET power MOSFETs designed specifically for active-clamp reset circuits in isolated dc/dc converters. The new 150V devices in the SO-8 package have 15 percent lower device on-resistance compared to previous generation p-channel devices in the larger D-Pak footprint, reducing power system size and cost in telecommunications and data communications equipment, according to IR.

The new MOSFETs optimize active-clamp reset circuits in 48V input, isolated, dc/dc converters using forward converter, flyback or similar topologies. The use of a p-channel MOSFET instead of an n-channel MOSFET simplifies drive circuitry since it eliminates the need for a high-side gate drive. In addition, the new devices have a lower breakdown voltage to further improve performance.

The IRF6216 and IRF6217 are available immediately. Pricing for the IRF6216 is $0.39 each, while the IRF6217 is $0.17 each in 5,000-unit quantities.
