Toshiba Electronics Europe TLP4590A

Supplied in a compact DIP6 package, the TLP4590A provides engineers with a more convenient and reliable alternative to conventional mechanical relays. This 1-Form-B (normally closed) photorelay with a MOSFET output, has an ON-state current rating of 1.2 A, which represents a 140% improvement on the previous-generation TLP4176A device. In addition, it has a 60 V OFF-state output terminal voltage rating. Its sensitivity is enhanced thanks to the low trigger LED current of 2 mA (maximum) exhibited. 

Key features

• 1-Form-B (normally closed)
