They worked great. Not much to say - as far as I can tell they adhere to the specs, and did the job I needed them to. Good transistors for higher current situations.

All current moves in switching devices with the proper selection of amp rating capability. I chose these to do a job that had to handle only 1/3 of it's rated capacity. So they were the perfect choice. To date they work as expected; perfectly.
