Small-signal MOSFETs save space for wearables

Small-signal MOSFETs save space for wearables
Diodes Incorporated has introduced three small-signal MOSFETs in a tiny DFN0606 package, measuring only 0.6x0.6mm. The 20 and 30V N-channel and 30V P-channel transistors require 40% less board space than the commonly used DFN1006 (aka SOT883) packaged MOSFETs, making them suited for next-gen wearables, tablets and smartphones.
