TechnologiesThe 2N65G-TN3-R is a MOSFET N Channel 650V 2A 1.4V @ 250uA 9.5O @ 1A,10V TO-252 RoHS manufactured by Unisonic Technologies. It is a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) which uses insulated gate terminals to control the flow of current. It is an N-Channel type, meaning it is a type of transistor that allows current to flow through it when a negative voltage is applied to the gate. The N-Channel type is normally off, meaning that it does not allow current to flow unless a negative voltage is applied to the gate. It has a voltage rating of 650V, a 2A current rating, a 1.4V at 250uA gate threshold voltage (Vt), and a 9.5 Ohm @1A, 10V drain to source resistance (RDSon). It is housed in a TO-252 RoHS compliant package which is a three-pin package, typically used for surface mount applications. The 2N65G-TN3-R is manufactured by Unisonic Technologies.
