------Question for [GBU8J](https://www.digikey.com/en/products/detail/diotec-semiconductor/GBU8J/13163524) Please Put your question below------

I do not see anywhere on the Diotec datasheet that the operating temp is. I cannot state it is -50 to +150 without backing document. DigiKey website is insufficient.

Hello,

It looks like the junction temperature on page one of the [datasheet](https://diotec.com/request/datasheet/gbu8a.pdf) shows a range of -50 to 150C.
