The BTA16, BTB16 and T16 series is suitable for general purpose AC switching. They can be used as an ON/OFF function in applica- tions such as static relays, heating regulation, in- duction motor starting circuits. or for phase control operation in light dimmers, motor speed controllers, . The snubberless versions (BTA/BTB.W and T16 series) are specially recommended for use on in- ductive loads, thanks to their high commutation performances. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rat- ed at 2500VRMS) complying with UL standards (File ref.: E81734).

The L78xxAB/L78xxAC series of three terminal positive regulators are available in TO-220, TO-220FP, and D2PAK packages and several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution problem associated with single point regulation. Each type employs internal current limiting, thermal shut-down and safe area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1 A output current, although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltage and currents.
