Working Principle

A power MOSFET is a type of power transistor that is characterized by very low power consumption and low thermal resistance. It is composed of a drain, a source, and a gate. The key factor of power MOSFET performance is its junction field-effect transistor (JFET) process. This technology allows the drain to be isolated from the gate and therefore allows for the generation of a high output power.

When a gate voltage is applied, the drain-source channel is opened and allows the electric current to pass through the channel. The gate voltage then adjusts the channel conductance and the flow of current. In addition, a positive source-drain bias will also increase the conductance and allow for higher electrical power output. The BLF9G20LS-160VU has a high power output due to its advanced JFET process.
