1. Applications ATE (Automatic Test Equipment) Measuring Instruments Factory Automation (FA) I/O Interface Boards Mechanical relay replacements 2. General
The TLP3145 photorelay consists of a photo MOSFET optically coupled to an infrared light emitting diode. It is
housed in a 4-pin package with 2.54-mm lead pitch and 2.1-mm height. The TLP3145 is a bi-directional switch,
which can replace mechanical relays in many applications. And its high on-state maximum rating current even
with medium voltage of 200 V and low on-state resistance is suitable to control a power line. 3. Features
