Hence, IFSM occurs as a single pulse only! Falls die Rt CL Zeitkonstante kleiner ist als ¼ der 50Hz-Netzperiode, kann CL innerhalb einer einzigen Netzhalbwelle komplett geladen werden. IFSM tritt dann nur als Einzelpuls auf! 2 http://www.diotec.com/ © Diotec Semiconductor AG R t 3) C L 4) ~ ~ + _ 120 100 80 60 40 20 0 [%] I FAV Rated forward current versus ambient temperature ) Zul.
