New ON Semiconductor ChipFETs in the leadless 1206A package features the same outline as popular 1206A resistors and capacitors but provide all the performance of true power semiconductor devices. The 1206A ChipFET has the same footprint as the body of the LITTLE FOOT[ TSOP–6, and can be thought of as a leadless TSOP–6 for purposes of visualizing board area, but its thermal performance bears comparison with the much larger SO–8. This technical note discusses the dual ChipFET 1206A pin–out, package outline, pad patterns, evaluation board layout, and thermal performance.
