BTA16, BTB16
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
Description
Available either in through-hole or surface-mount
packages, the BTA16, BTB16, T1610 and T1635
Triacs series are suitable for general purpose
mains power AC switching.
