he World's Largest-Capacity 8kV/3.6kA Light-Triggered Thyristor by Katsumi sato* Mitsubishi Electric has developed an 8kV/3.6kA light-triggered thyristor (LTT) based on a six inch wafer for power-converter applications in igh-voltage DC transmission and back-to-back systems. New design features give the device

VDRMI VARM =10ms 1/2 sine. Vosu V asM =VDRM+ 100V respectively. Lower voltage grades available. ORDERING INFORMATION When ordering select the required part number shown in the Voltage Ratings selection table r ex For example:

The Bipolar Junction Transistor The term Bipolar is because two type of charges (electrons and holes) are involved in the flow of electricity The term Junction is because there are two pn Junctions There are two configurations for this device n-type p-type n-type
