calling master T, may update na dito?
mas better master T ang heat dissipation
master tony anong simulation gamit mo
sir tony,pag inassemble mo ang amp na to gaano kaya kalaki chassis nito at estimated amount?true RMS power output amp na yan?
to summarize:2SC5200/2SA1943 ------ 16 pairsMJL21193/MJL21194 ----- 11 pairsMJ21193/MJ21194 ------- 8 pairsTIP35C/TIP36C ---------- 22 pairsnotice that up to this point i have not mentioned about the device dissipation Pd max, i have thus far tackled, Vceo and Ic....The reason we do not use this spec as a figure of merit as it has not much use to us in designing amps....looking at 2SC5200, at dc operation and if case is held to a temp of 25*C it can dissipate 150 watts, so that if heatsinking is such that case temperature reaches 50*C it can still dissipate 75 watts......but we do not want to operate our trannies this way, we want to have it to operate at much lower temperature as heat is the number one killer of solid state devices....the MJL21193/94 otoh while rated at 200watts at 25*C case temp has a soa of 150watts at 25*C.... the TIP35C/36C is rated at 125 watts at 25*C case temp has only 50watts soa at case temp of 25*C....SOA were taken at dc curves, 50 volts, except for the MJL21193/94 which has only a 1sec curve provided....
