Mosfet body current
WebHello Someno San, Thanks for your questions. 1. Yes, you are correct in theory that the body diode can support the same current as the FET. Please note, the body diode has a constant voltage drop and is therefore limited by power loss in the actual application to keep the device within the datasheet maximum temperature limits. WebThe body of the transistor is made of the substrate. In this figure, ... This would mean less current would flow and this type of MOSFET would be considered a “normally-closed” …
