TYN640

TYN640, TYN840 A G K A K A G TO-220AB 40 A standard SCRs Datasheet - production data Description These standard SCRs are suitable for applications where in-rush current conditions are critical, such as overvoltage crowbar protection circuits in power supplies, in-rush current limiting circuits, solid state relays (in back to back configuration), welding equipment, high power motor control circuits. Using clip assembly technology, they provide a superior performance in high surge current capabilities. Table 1.
