TLP172 Photorelay Photocouplers

Toshiba TLP172 Photorelay Photocouplers offer ON/OFF control for high current. These photo relays contain a photo-MOSFET optically coupled with a gallium arsenide (GaAs) infrared-emitting diode. The TLP172 is 2.1mm in height with a 2.54mm pitch. Specifications include normally opened (1-Form-A), off-state output terminal voltage of 60V or 350V (min.), and 3mA (max.) trigger LED current. These photo relays are suitable surface mount assemblies. Ideal applications for TLP172 Photorelays are factory automation (FA), mechanical relay replacements, measuring instruments, battery management systems (BMS), security systems, and more.
