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, Snubberless™)
capability
• BTA series UL1557 certified (file ref: 81734)
• Packages are 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 and
T1610, T1635 and T1650 Triac series are suitable for general purpose mains power
AC switching. They can be used as ON/OFF function in applications such as static
relays, heating regulation or induction motor starting circuit. They are also
recommended for phase control operations in light dimmers and appliance motors
speed controllers.
The Snubberless™ versions (W suffix and T1610, T1635, T1650) are especially
recommended for use on inductive loads, because of their high commutation
performance.
By using an internal ceramic pad, the Snubberless™ series provide an insulated tab
(rated at 2500 VRMS) complying with UL standards (file reference: E81734).
