HI FRIENDS.

I'M  IMPLEMENTING  A DIMMER WITH A DIMMER I.C ( PHASE CONTROL )
MY LOAD IS 100W INCADECENT LAMP AND THE INPUT VOLTAGE IS 230V 50HZ.
THE POWER STAGE - INCLUDES TRIAC-PHILIPS-BT138, A SERIAL RFI CHOKE - 60
microHenry,  A PARALEL CAPCITOR -100NF/275VAC , THE CAPACITOR IS PARALEL TO
THE LAMP AND THE CHOKE.
WHEN I TURN ON THE TRIAC BY APLYING CONSTANT CURRENT TO THE GATE - ALL ITS
FINE.
BUT, WHEN THE TRIAC GOT A PULSE IN IT'S GATE ( B.W=33 microsecond from the
DIMMER I.C - EVERY HALF CYCLE.) AFTER SOME MINUTES ,THE TRIAC BECAME  VERY
HOT!!!!!
CAN ANYONE HELP ME TO SOLVE THE PROBLEM??

THANK YOU VERY MUCH.
MOSES.
