Abstract
Operating a double-sided double-base bipolar junction transistor. At least one example is a method of operating a switch assembly, the method comprising: conducting a forward load current from an upper terminal of the switch assembly, into an upper collector-emitter of a double-sided double-base bipolar junction transistor (DSDB-BJT), through the DSDB-BJT, out through a lower collector-emitter of the DSDB-BJT, and then through a lower terminal of the switch assembly; and then ceasing conduction of the forward load current. The ceasing conduction of the forward load current may be by: coupling a lower base of the DSDB-BJT to the lower terminal; and driving a pinch-off voltage to the lower collector-emitter of the DSDB-BJT to reduce reverse recovery current through the lower base.
