Fast recovery diodes work by themselves and with thyristors as solid state switches and snubber devices. The diodes’ low reverse recovery times facilitate high speed switching. Fast recovery also protects insulated-gate bipolar transistors (IGBTs) and integrate gate-commutated thyristors (IGCTs) against commutation failures. Through our IXYS subsidiary, Littelfuse offers several kinds of fast recovery diodes with a wide variety of performance characteristics.
