and welding power supplies where high pulse currents and sustained load cycling are routine operational conditions requiring a thermally capable and electrically stable switching device
including both current-production and hard-to-find obsolete parts
Integrated thyristor and diode elements in a single isolated-base module reduce PCB footprint and simplify thermal management
and rectifier modules — including hard-to-find and long-lead-time parts like the QM30TB-2HB
SKKT71/16D-SEMIKRON Desc and welding power supplies whereThe SKKT71 16D is a dual SCR (thyristor) module manufactured by SEMIKRON, rated for 71A average on state current and a 1600V repetitive peak off state voltage (VDRM VRRM). Built in SEMIKRON's proven SEMIPACK form factor, this module integrates two thyristors in a common base configuration, enabling straightforward implementation in fully controlled bridge rectifier and AC power controller topologies. Its robust silicon construction, low thermal
