F Flyback Well-Known Member Aug 10, 2017 #1 Hello, We have a DALI signal which comes into our non isolated offline LED driver. The DALI signal is isolated from the receiver in the LED driver by a TCLT1000 optocoupler.. TCLT opto datasheet https://www.vishay.com/docs/83515/tclt1000.pdf The problem is , that its too long to fit on the PCB. We need to use a smaller opto….. Do you think we will be able to use the LTV-356 optocoupler which is 3mm shorter…. https://www.mouser.com/ds/2/239/LTV-356T Series-1308-301539.pdf Will the clearance still be adequate with the LTV-356 opto? Also, if not, then can we just use a cutout in the PCB to increase clearance like that?
