BTA04
TRIAC
SENSITIVE GATE TRIAC
DESCRIPTION

The UTC BTA04 is a 4A triac, it uses UTC’s advanced
technology to provide customers with high commutation
performances and voltage insulated tab, etc.
The UTC BTA04 is suitable for inductive loads, general
purpose AC switching and an ON/OFF function in applications
such as induction motor starting circuits, for phase control
operation in light dimmers and static relays, etc.
FEATURES

* Low gate trigger current
* Low holding current
