Triacs fit for industrial, control apps

ON Semiconductor has expanded its high performance triac portfolio with the introduction of 12 new triacs with available power ratings of 8A, 12A and 16A with Gate Trigger Current (Igt) levels of 35mA and 50mA. The BTAxxxx series of devices are fit industrial and control applications where isolation voltage is critical and safety is a primary concern.

Both the BTAxxx and non isolated equivalent, BTBxxx series, utilize the latest silicon and package designs that optimized die area and package construction improving device performance resulting in the release of high performance devices at a competitive price.

The new BTA08-600BW3G, BTA08-800BW3G, BTA12-600BW3G, BTA12-800BW3G, BTA16-600BW3G, BTA16-800BW3G, BTA08-600CW3G, BTA08-800CW3G, BTA12-600CW3G, BTA12-800CW3G, BTA16-600CW3G, BTA16-800CW3G triacs provide best-in-class isolation performance, high Igt for snubberless designs, excellent dV/dt for improved noise immunity and three quadrant operation, says ON Semiconductor. Soon to be released product line expansion will include sensitive gate and four quadrant operation.

"The new BTAxxxx triacs from ON Semiconductor represent the company's entry into the isolated package market for thyristors, building on its long history in supplying SCR's and triacs," said M.K. Mak, VP of worldwide marketing of ON Semiconductor's Standard Products Group. "Every designer is under pressure to improve the safety and efficiency of his or her design. The new triacs and SCR's from ON Semiconductor can play an important role in any system where safe and efficient AC power switching is required. They add additional safety that comes from the very high isolation voltage of a fully internally isolated package and are a compliment to our recently released BTBxxx series of triacs".

The devices are available in an Isolated TO220 package. The BTAxxx are priced at $0.45 for the 8A version, $0.47 for the 12A, and $0.54 for the 16A version per unit for 1,000 unit quantities.
