UTC UNISONIC TECHNOLOGIES CO., LTD. 1 TRIACS SYMBOL DESCRIPTION

Transcription

1 S DESCRIPTION Glass passivated triacs in a plastic envelope, intended for use in applications requiring highbidirectional transient and blocking voltage capability and high thermal cycling performance. Typical applications include motor control, industrial and domestic lighting, heating and static switching.
