Small-outline photorelay has low trigger current
The TLP175A is suitable for designs that demand high-reliability switching and improved efficiency while saving board space. It provides a smaller, more reliable, longer life and lower power alternative to mechanical relays. Minimum creepage and clearance distances of 5.0 mm and an internal isolation thickness of 0.4 mm (min) contribute to a minimum isolation voltage rated at 3750 Vrms.
The photorelay’s 4-pin SO6 package incorporates an infrared LED that is optically coupled to a photo MOSFET. Package dimensions are 7.0 x 3.7 x 2.1 mm. A 1mA current is all that is required to trigger the LED and turn the photorelay on. Featuring a normally open (1-Form-A) configuration, the TLP175A has an OFF-state output terminal voltage of 60V and a maximum ON-state current of 100 mA. Performance is guaranteed for operating temperatures between -40°C and 85°C.
