Bi-Directiona! Triode Thyristor 53 STUD/; lance Hermetic Triacs SC240 6A to 40A RMS_ Up to 600 Volts $Cc245 The triac is a silicon AC switch which may be gate triggered from an OFF- $C260 State to an ON-State for either polarity of applied voltage. These triacs are S$C265 hermetically sealed devices which incorporate General Electrics patented POWER-GLAS process that improves upon normal passivation techniques. It provides an intimate bond between the silicon chip and the glass coating. P RESS-F IT The resulting stable, low-level leakage current provides excellent performance nares and demonstrated reliability. c241 FEATURES: $C246 POWER-GLAS passivated silicon chip for maximum reliability. $C251 e Very low off-state (leakage) current at room and elevated temperatures. e Inherent immunity from non-repetitive transient voltage damage (max. Sc261 critical rate-of-rise of on-state current subsequent to voltage breakover triggering, di/dt = 10 A/usec.) SC266 e Low on-state voltage at high current levels. e Excellent surge current capability. e 1800 volts RMS Surge Isolation Voltage on Isolated Triacs. e Selected types available from factory for use where circuit requires operation: -- with popular zero voltage triggering ICs at 400 Hz with low gate trigger current -- at higher voltage levels at higher commutating dv/dt levels.

Heatsink materials may be copper, aluminum, or steel. For maximum heat transfer and minimum corrosion problems, copper is recommended. The heatsink thickness, or amount of heatsink wall, in contact with the Triac should be 1/8 inch. 2. The hole diameter into which the Triac is pressed must be 0.4975 + .001 inch. A slight chamfer on the hole should be used, This hole may be punched in a flat plate and reamed, or extruded and sized in sheet metal. 3. The entire knurled section of the Triac should be in contact with the heatsink to insure maximum heat transfer. The Triac must not be inserted into a heatsink deeper than the knurl height. 4. The Triac insertion force must not exceed 800 pounds. If the insertion force approaches this value before complete insertion, either the Triac is misaligned with the hole or the Triac-to-hole interference is excessive, The insertion force must be uniformly applied to the top face (terminal end) of the Triac within an annular ring which has an inside diameter of not less than 0.370 inch and not larger than 0.390 inch; the outside diameter of the insertion force must not be less than 0.500 inch. 5. The thermal resistance between the Triac case and a copper heatsink will not exceed 0,5C/W, if the Triac is inserted in the manner described. Soldering of Press-Fit Package to Heat Sink The press-fit package may be soldered directly to a heatsink using 60/40 (Pb-Sn) solder at a temperature of about 200C. Attachment of Press-Fit Device to Printed Circuit Board For certain light load applications, the Triac can be inverted and, using a special brass bracket (A7149451), dip-soldered into a printed circuit board. The feet on the bracket act both as a mechanical support and Main Terminal 2 (case) electrical connection. For Triacs preassembled into the bracket, add X24 to the type number, for example, SC251BX24, PRINTED yt} a CIRCUIT BOARD Pr LLLL1L Ko} [oJ] pie sotper _/ ALL 3 CONNECTIONS CONNECTIONS L 3 GONNECTIO BOTTOM VIEW OF ASSEMBLY SEFORE MOUNT ING TO BOARD Attachment of the Stud & Isolated Stud Device To a Heat Sink These devices require certain precautions in order to insure good thermal transfer. The chassis hole must be drilled and deburred, and should be between .005 and .015 inches larger than the stud outside diameter. The use of a Torque wrench is highly recommended and must be used within the torque limits indicated on page 2. A good grade of silicone grease will minimize contact thermal resistance.
