It's rated 1.4 watts, but saturates really low, excellent beta at 2 amps. A SOT89 on a decent copper pour is happy at 3 watts, but this ST part is rated 1.4 watts on 1 cm^2 of PCB. For a real 3-watt rated part, you'll probably have to go DPAK or some such. Why not use the Digikey or Mouser search engines? -- John Larkin Highland Technology, Inc jlarkin att highlandtechnology dott com http://www.highlandtechnology.com |
