Podzespoły MG12600WB-BR2MM - półmostkowe moduły IGBT 1200 V/600 A
Firma Littelfuse wprowadziła do oferty serię półmostkowych modułów IGBT MG12600WB-BR2MM przeznaczonych do zastosowania w sterownikach napędów przemysłowych, falownikach, spawarkach i zasilaczach UPS o dużej mocy. Moduły mają napięcie przebicia 1200 V i większy, dopuszczalny prąd obciążenia w porównaniu do wcześniej oferowanych - 600 A zamiast 450 A.
Jednocześnie są z nimi kompatybilne pod względem sterowania i wyprowadzeń, dzięki czemu mogą być stosowane zamiennie w razie potrzeby zapewnienia większej mocy zasilania dostarczanej do obciążenia. Moduły z serii MG12600WB-BR2MM są oferowane w obudowie o wymiarach 152 mm×62 mm×17 mm z terminalami śrubowymi o konfiguracji WB.
W modułach zastosowano technologię Trench-gate Field Stop IGBT zapewniającą małe straty wskutek przewodzenia i przełączania. Oprócz tego zapewnia ona małe napięcie nasycenia i dodatni współczynnik temperaturowy, co ułatwia równoległe łączenie modułów.
