Vishay VO615A spice model in TINA

James Crow

Other Parts Discussed in Thread: TINA-TI

I got the spice model for an opto-transistor from the Vishay website, but when I created the model in TINA it does not function correctly. Please let me know what I did wrong. Thank you.VO615A.TSC

James,

I took a look at the model and see no obvious reason why it would not work in TINA-TI. I also pulled the application note for the model and tested it per their diagram and found that the input side appeared to function as I would expect, but the output just stayed at about 5V. Let me ask around to see if we can find out why it works in PSpice and does not show the same response in TINA-TI.

James,

Please take a look at the attached .TSC file that should correct the problem. This is the application circuit that is used in the application note for the Opto from Vishay. There was a small issue with the model file (not a problem in PSpice, but TINA-TI has a smoothing function that needed an additional point in the table model). This corrected the problem.

Please let me know if you have any additional questions.
