SiC JFETs

SiC JFETs . . . The ideal circuit protection solution

Current Limiting: Rapid current decrease due to self-heating, limiting I2t

Normally-On JFETs: VTH invariant with temperature

Ability to handle peak TJ>600C, upto the melting point of Al

Current limiting function

jfet02

Back-to-Back Normally-On JFETs lead to a bidirectional current limiting device. Low series resistance, excellent current limiting behavior.

High Side Switch (DC Breaker)

jfet03

Normally-On JFETs are used to create self-powered two-terminal fast acting circuit breakers.
