gogo2520 Posted March 2, 2006 Report Share Posted March 2, 2006 Hello I have been reading data sheets and could use some help. I wan to build the power supply on the LM350 data sheet. The problem is in one of the power transisters MJ4502, I don't have one and I would rather use something I have instead. What I have is heaver the the MJ4592. I was thinking of useing a 2N5416, the voltate and current rateings or higher but the hfe is not the same. The MJ4502 hfe is 25 - 100, the 2N5416 hfe is 30 - 120. So I guess my question is will that still work? Quote Link to comment Share on other sites More sharing options...
ante Posted March 8, 2006 Report Share Posted March 8, 2006 Hi gogo,No, the 2N5416 is only 1A and will not replace the 30A MJ4502! (smoke)!You could use two 2N2955 in parallel if you like with 0R1 5W on each emitter! Quote Link to comment Share on other sites More sharing options...
gogo2520 Posted March 9, 2006 Author Report Share Posted March 9, 2006 Hi Ante I would use a MJ4502 if I could find one. I only going to build a 2 or 3 amp power supply. I'll Keep looking. Two 2n2955 will work, have to see if I can find them. Thanks Ante gogo Quote Link to comment Share on other sites More sharing options...
