T1610, T1635
16 A Snubberless™, logic level and standard Triacs
Features
■ Medium current Triac
■ Low thermal resistance with clip bonding
■ Low thermal resistance insulation ceramic for
insulated BTA
■ High commutation (4Q) or very high
commutation (3Q) capability
■ BTA series UL1557 certified (File ref: 81734)
■ RoHS ( 2002/95/EC) compliant
■ Insulated tab (BTA series, rated at 2500 VRMS)
Applications
■ Snubberless versions (BTA/BTB...W and
T1635) especially recommended for use on
inductive loads, because of their high
commutation performances
■ On/off or phase angle function in applications
such as static relays, light dimmers and
appliance motor speed controllers
