In a FET, the depletion zone stretches from the gate region ... So we’ve described the FET, and noted that while its mode of operation is different to that of a bipolar transistor it does ...

An enhancement MOSFET needs a voltage applied to a gate for the device to turn on, it can be thought of as a normally closed switch as opposed to a depletion mode device which needs a gate voltage ...

Infineon is one of the few semiconductor manufacturers worldwide to offer depletion MOSFETs. Areas of application include power supply startup power, over-voltage protection, in-rush-current limiter, ...

Others meet U.S. military specifications (MIL-SPEC). MOSFET RF transistors vary in terms of operating mode, packaging, and packing methods. Devices that operate in depletion mode can increase or ...
