Fast fuses are commonly used to protect semiconductor devices and rectifier diodes and thyristors in power frequency rectifier circuits.
For other power electronic devices, such as fast thyristor, high frequency thyristor, high power transistor, power field effect transistor, etc., the fusing time of fast fuse is still too long, generally can not be directly used to protect the fast fuse.
