Technical documentation and image source
The linked manufacturer table explicitly gives a maximum operating junction temperature. A minimum operating temperature is not specified in that table and remains unconfirmed; the separately labeled storage temperature range is not an operating range. Complete ordering code, function description and exact literal package come from the independently reparsed manufacturer order card. Pin count and manufacturer package reference are independently crosschecked. The image is not a current-lot photograph or guaranteed marking. No complete electrical qualification or full temperature range is claimed.
Manufacturer package reference image for TO-220. Confirm electrical pin functions in the datasheet. Actual lot appearance and top marking require current-lot confirmation.
Some exact-order specifications remain to be confirmed in the manufacturer documentation.
