Description
The ACPL-K30T is specially designed to drive high-voltage
MOSFETs. It consists of an AlGaAs infrared Light-Emitting
Diode (LED) input stage optically coupled to an output
detector circuit. The detector consists of a high-speed
photovoltaic diode array and a turn-o circuit. The pho-
tovoltaic driver is turned on (contact closes) with a mini-
mum input current of 5 mA through the input LED. The
relay driver is turned o (contact opens) with an input
voltage of 0.8 V or less.
ACPL-K30T is available in the stretched SO-8 package
outline, designed to be compatible with standard surface
mount processes.
