Product details

The 83 W power dissipation at the case (Tc) assumes a proper thermal interface to a heatsink or PCB copper plane; the 3.1 W at ambient (Ta) is the free-air limit — derate from there if the board is in a sealed enclosure.

No last-time-buy or end-of-life notice is on record for this order code.
