Test voltage must be applied within dv/dt rating. Note 3. This device is guaranteed to trigger at an IF1 value less than or equal to max. IFT. Therefore, recommended operating IF lies between max. IFT (15mA) and absolute max. IF (60mA). Note 4. This is static dv/dt. Commutating dv/dt is a function of the load–driving thyristor only. 6 Pin Connection Diagram Anode 1 6 Main Terminal Cathode 2 5 Substrate Do Not Connect N.C. 3 ZERO CROSSING CIRCUIT 4 Main Terminal 1 5 4 2 3 .260 (6.6) Max .070 (1.78) Max .350 (8.89) Max .200 (5.08) Max .085 (2.16) Max .300 (7.62) .350 (8.89) Max .100 (2.54)
