T tytower Banned Oct 11, 2010 #1 I am looking for a replacement for this . Hopefully something I can get at Jaycar. They don´t seem to have ths one so what would I use instead- its used as a power switch I think TO220 case Last edited: Oct 11, 2010

T tytower Banned Oct 11, 2010 #4 All I could find in my box was 2 off D45H2A which seems to be a power transistor so Iĺl give one a try first- yep this worked and I ran it for a few hours and it was pulling about 400mA. https://www.electro-tech-online.com/custompdfs/2010/10/d45h2a.pdf The original is indeed a2SA1012L https://pdf1.alldatasheet.net/datasheet-pdf/view/172864/UTC/2SA1012L-O-TA3-R.html DC current gain is given as 70 to 240 Ic=1A (the fuse is 1 A) Last edited: Oct 12, 2010
