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)
  • VOFF = 60 V/ION = 1.2 A
  • Low trigger current 2 mA
  • High isolation voltage BVs = 5000 VRMS

Additional features

  • Direct replacement of mechanical relays together with 1-Form-A (normally open) device
  • Long lifetime and high reliability compared with mechanical relays
  • Operation temperature range from -40 to +110 °C
  • Can be used in harsh environments
