Top 7 JFET Manufacturers in the World

Junction Field Effect Transistor (JFET) is a three terminal semiconductor component, which are majorly categorized as n-channel and p-channel. JFET’s three terminals are source, drain and gate. Unlike BJT, JFET is a voltage-controlled device as here the potential applied at the gate terminal controls the drain current. In a junction field-effect transistor or JFET, the controlled current passes from source to drain, or from drain to source as the case may be. The controlling voltage is applied between the gate and the source. Here, we have focused on the top JFET manufacturers in the world;

MicrochipMicrochip’s junction field-effect transistor (JFET) is the simplest type of field-effect transistor. They are three-terminal semiconductor. JFETs are voltage-controlled. Electric charge flows through a semiconducting channel between source and drain terminals. By applying a reverse bias voltage to a gate terminal, the channel is “pinched”, the electric current is switched off completely.

A JFET is usually on when there is no potential difference between its gate and source terminals. If a potential difference of the proper polarity is applied between its gate and source terminals, the JFET will be more resistive to current flow. JFETs are sometimes referred to as depletion-mode devices. The company is among the top JFET manufacturers in the world.

GeneSiC Semiconductor

GeneSiC SemiconductorJFETs offered by GeneSiC exhibit ultra-fast switching capability, a square reverse biased safe operation area (RBSOA), as well as temperature-independent transient energy losses and switching times. These switches are gate-oxide free, normally-off, exhibit positive temperature co-efficient of on-resistance, and are capable of being driven by commercial, commonly available 15 V IGBT gate drivers, unlike other SiC switches. While offering compatibility with SiC JFET drivers, Junction Transistors can be easily paralleled because of their matching transient characteristics. The company is among the top JFET manufacturers in the world.
