BTA24, BTB24, BTA25
BTA26, BTB26, T25
25 A standard and Snubberless™ triacs
Features
High current triac
Low thermal resistance with clip bonding
High commutation (4 quadrant) or very high
commutation (3 quadrant) capability
BTA series UL1557 certified (File ref: 81734)
Packages are RoHS (2002/95/EC) compliant
Applications
Applications include the ON/OFF function in
applications such as static relays, heating
regulation, induction motor starting circuits, etc.,
or for phase control operation in light dimmers,
motor speed controllers, and silmilar.
The snubberless versions (BTA/BTB...W and T25
series) are especially recommended for use on
inductive loads, due to their high commutation
performances. The BTA series provides an
insulated tab (rated at 2500 VRMS).
Description
Available either in through-hole or surface-mount
packages, the BTA24, BTB24, BTA25, BTA26,
BTB26 and T25 triac series is suitable for general
purpose mains power AC switching.
