5kVrms-Rated Photorelay Device Attains Elevated Reliability Characteristics

06 January 2024

The TLP241BP photorelay from Toshiba is a 1-Form-A/normally open (NO) device supplied in DIP4 packaging.

This device presents a highly effective alternative to using mechanical relays - with advantages being derived in terms of ongoing performance, invulnerability to ambient noise and compactness too. It supports a 5kVrms input-output isolation voltage. The photorelay delivers a continuous on-state current of 1.4A and 4.2A for pulsed operation. It also has an 80V off-state output terminal voltage. Built-in over-temperature and over-voltage protection mechanisms have been incorporated for assured long-term reliability. A -40°C to +110°C working temperature range can be coped with.
