The six-lead SC-89 Little Foot is a low-resistance MOSFET measuring 0.6 mm high with a 2.56-mm2 footprint. The device comes in two single p-channel versions, the Si1039X and the Si1037X, with respective ratings of 165 and 195 m ohms at a -4.5-V gate drive. Each can handle up to 0.95 amp. Another version, the Si1040X, comes in both n- and p-channel models and includes a level shift to allow a low-voltage microcontroller to control loads on a range of different voltage rails. The n-channel version has internal ESD protection and can be driven by logic signals as low as 1.5 V. Available now, the SC-89 is priced at 22 cents each per 100,000.
