BSS123I

Active and preferred

The OptiMOS™ N-channel MOSFET 100 V in SOT-23 package features low RDS(on) of 6 Ohm (at VGS 10 V). With an optimal price/performance ratio and small footprint, our small signal and small power MOSFETs are the best fit for a wide range of applications and circuits. These include low voltage drives, linear battery charger, battery protection, load switches, DC-DC converters, reverse polarity protection and many more.
