Abstract
A drive control circuit for a junction field-effect transistor having a gate terminal, a drain terminal and a source terminal as well as a gate leakage current and a maximally permissible gate current, includes a current supply which feeds the gate and produces a control current which is greater than the gate leakage current and smaller than the maximally permissible gate current for turning the junction field-effect transistor off.
