2015年5月27日 · Is there anything available to see if a particular transistor can be replaced with a different one . There are books galore on this but surely someone knows of a site that has them listed and searchable My query is a simple one I have no 2N5551 transistors on hand and I want to see if one in my...

2004年6月27日 · I was at the local electronics store trying to find a large amount of 2N3053 transistors, and they said they not being produced anymore, but they had an equivalent that was $1.40US each. Does anyone know of another common NPN transistor with the same power dissipation that it does? (at a lower...

2008年7月19日 · I have seen many circuits using the 2N2222 transistor (correct me if it isn't one). one of them uses it to control electrical appliances. It says it can be substituted by a BC148. So I just wanted to know can the BC148 be used as a general substitute for …

2008年12月19日 · Transistor495, I may still have some left in my box. Old but original unsed. Digikey has quite a lot of stuff that I want but they demand USD30 for delivery to Malaysia.

2009年9月22日 · You might try "ECA" for transistor comparison books. E.g. looking up 2N222 you'll find the equivalent "BC" type, here BC547. 2Nxxx and BCxxx are slightly different in collector current and, as already mentioned by audioguru, they are sometimes different in pin layout. BC-transistors are all E-B-C, 2N types might be B-E-C.

2007年6月20日 · I was wondering what are some modern replacements for 2 common transistors that I use: PN2907A PN2222A They must be non-amplifying, TO-92 package transistors. THANKS

2006年10月13日 · A single booster transistor can charge, or discharge the high capacitance but not both. You need 2 booster complimentary emitter follower transistors, an NPN to pull high to charge the capacitance and a PNP to pull low to discharge the capacitance.

2012年2月7日 · Paste it at the top of the other transistor models in that file, Save the standard.bjt file. Run LTspice and using F2 , select a 'npn' transistor an place the symbol on your circuit. Right click on the transistor symbol and then 'pick new transistor button', your NEW transistor 2N3393 should appear, select it.

2009年12月12日 · I Found Some Tutorial For Choosing The Right Substitution of Transistor . As The Tutorial I Choose Two High Power NPN Transistor . Their Configuration As Below - C4304 C4908 C4020 Vcbo = 900 V 900 V 900 V
