Dear Technical Support Team,
Could you give me a dissipation Ratings information of PS package?
Datasheet doesn't have it below.
Best Regards,
ttd

Hi TTD,
Thanks for reaching out on E2E. Unfortunately, seeing this is an older device (released in 1967), we don't have detailed thermal information in our database. Can you provide more detail regarding the customer application, we might be able to calculate the thermal dissipation with the information provided in the datasheet.
If the device hasn't been designed in, I recommend looking at our newer low side drivers including the TPL7407LA and the ULN2003A.
Thanks,
Arthur Huang
Hi TTD,
I tried working backwards in my calculations to extract the dissipation ratings from the PS thermal information and the junction temperature, but I was unable to get a concrete value. I also looked at our database and was unable to find any dissipation ratings, due to this being an older device.
Based on thermal information, since the D package performs slightly worse than the PS package, you could use the D Dissipation Ratings as a conservative estimation of the PS ratings. The PS package should perform better than the results you get with the D package, but this could work as an estimation.
Thanks,
Arthur Huang
