Drive control circuit for a junction field-effect transistor |
摘要 |
A drive control circuit for a junction field-effect transistor having a gate terminal, a drain terminal and a source terminal, includes a controllable current supply or voltage supply to produce a reverse control current or a reverse control voltage for the gate. The current supply or voltage supply is controlled in such a way that upon a switch-off of the junction field-effect transistor, the absolute magnitude of the reverse control current or the reverse control voltage assumes initially a higher value and then a lower value, whereby the lower value is sufficient for blocking the junction field-effect of the transistor.
