TLP3127
1. Applications
• High-Speed Memory Testers
• High-Speed Logic IC Testers
• Factory Automation (FA)
• Power supplies
• Mechanical relay replacements
2. General
The TLP3127 photorelay consists of a photo MOSFET optically coupled to an infrared LED. It is housed in a 4-
pin package with 2.54-mm lead pitch and 2.1-mm height. The TLP3127 is a bi-directional switch, which can
replace mechanical relays in many applications. And its high on-state current maximum rating and low on-state
resistance is suitable to control a power line.
