TO-220AB Insulated
(BTA24)
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).

In order to meet environmental requirements, ST offers these devices in ECOPACK®
packages. These packages have a lead-free second level interconnect. The category of
second level interconnect is marked on the package and on the inner box label, in
compliance with JEDEC Standard JESD97. The maximum ratings related to soldering
conditions are also marked on the inner box label. ECOPACK is an ST trademark.
ECOPACK specifications are available at: www.st.com.
