MOSFET plus Schottky diode reduce space and cost
By Bill Schweber -- EDN, 11/8/2001
Expanding on its FETKY family, International Rectifier has introduced two p-channel MOSFETs, copackaged with Schottky diodes on the same heat spreader, in SO-8 packaging (Picture). The copackaging also reduces stray inductance and pc-board resistance, thus reducing voltage spikes and inefficiency. Both the IRF5803D2 and the IRF7342D2 target use in buck-converter designs and use 60% less board space than discrete implementations. The 40V IRF803D2 has a maximum 0.112Ω RDS(ON) at 10V, and the 55V IRF7342D2 has a 0.105Ω RDS(ON). The devices cost 37 and 46 cents (10,000), respectively.
