Littelfuse, Inc. Datasheets for Metal-Oxide Semiconductor FET (MOSFET)

Metal-oxide semiconductor field-effect transistors (MOSFETs) are electronic switching devices with a conducting channel as the output. An electrode called a gate controls the width of the channel and determines how well the MOSFET conducts.

Product Name Notes
As opposed to the enhancement-mode MOSFETs, these depletion-mode devices operate in a ‘normally-on’ mode, requiring zero turn-on voltage at the gate terminal. With blocking voltages up to 1700V and low...
Depletion mode MOSFETs, unlike the regular enhancement type MOSFETs, require a negative gate bias to turn off. Consequently they remain on at or above zero gate bias voltage but otherwise...
