TrenchFET MOSFETs Boast Super-Low On-Resistance

A new series of TrenchFETs, housed in the tiny LITTLE FOOT SC-89 and SC-75 packages, feature on-resistance as low as 1.25_. The Si1012X, which comes in the 3-pin LITTLE FOOT SC-89 package, is a single n-channel 20V TrenchFET with on-resistance of just 1.25_ at a 1.8V gate drive, said to be 76% lower than any competing device in the same package. Fully on at a gate-source voltage of 1.8V, the device requires significantly less power to operate than the digital bipolar transistors it is intended to replace. The new device also features a 500 mA steady-state continuous drain current and a 5 ns turn-on time. Another member of the series, the Si1024X, combines two MOSFETs in a 6-pin SC-89 package with the same specifications per channel as the Si1012X. Pricing is less than $0.10 each/100,000.
