INVERTER THYRISTOR
C770 & C770A
77mm / 1800V / 60-80us
Disc-type ceramic PRESSPAK package
Type C770 reverse blocking thyristor is suitable for inverter applications.The silicon junction
is manufactured by the proven multi-diffusion process and utilizes the exclusive involute gate
structure.It is supplied in an industry accepted disc-type package , ready to mount using
commercially available heat dissipators and mechanical clamping hardware.
