PicoSSR 3 is the world's smallest MOSFET for AEG. Even though its dimensions are merely 4x6x21 mm, PicoSSR 3 is very powerful. It has great electrical and mechanical parameters and fits replicas with little space for MOSFET.
Additionally, it is fully resistant to water immersion (after heatshrink tube fitting). It can work with the strongest AEG replicas - maximum battery rated voltage is 12.8V.
