Updated July 18, 2020. Just a few points for the record. The BC548 is a part of a family of NPN and PNP epitaxial silicon transistors that originated with the metal-cased BC108 family of transistors.The BC548 is the modern plastic-packaged BC108; the BC548 article at the Radiomuseum website describes the BC548 as a successor to the BC238 and differing from the BC108 in only the shape of the package. When I talk about. How avoid overvoltages when there is loss of neutral in electricity supply system?

Part Category: Transistors Manufacturer: Texas Instruments High-Performance Analog Description: Small Signal Bipolar Transistor, 0.1A I(C), 30V V(BR)CEO, 1-Element, NPN, Silicon, TO-92 Find Equivalent … The BC548 transistor might have a current gain anywhere between 110 and 800.The gain of the BC548A will be in the range from 110 to 220, BC548B ranges from 200 to 450, BC548C ranges from 420 to 800. Right, thanks, could you give me an example of a general purpose NPN transistor, would a BC 108 do? I find sl100 comparison npn transistor bc548b working equal to SL 100 transistor.... MikeMl Well-Known Member. I'm trying to find an equivalent for the SL100 transistor but I don't understand how to do this. Converting mains to 300Hz in order to reduce size of PFC equipment. The SL100 is also in a metal can, so probably has a lower thermal resistance junction/ambient than plastic case types. Most Helpful Member. OK. the circuit works on 9v supply. For a better experience, please enable JavaScript in your browser before proceeding. So with a such voltage operation BC108 can be used. Copyright © 2020 WTWH Media, LLC. I am an engineer and an academic. For that circuit any general purpose NPN transistor may be used. This post describes the BC546 transistor pinout, equivalent, uses, features and some other useful information about this transistor.
