Hi Ian , the transistor is basically a surface mount version of the BC if the pcb design makes it possible ,you could try a TO92 plastic NPN transistor like a BC or BC can try maplin for this otherwise try ebay , RS components or farnell for a BC what is the transistor used in ,and how many do you need?
Hi johnstij I have some, BCB. The B suffix is for hfe range, so if yours lacks the suffix they will be perfect. How many do you need? Engaged in the art of turning large pieces of useful material into ever smaller pieces of s crap. Ferndown, Dorset. Thanks for the replies. I'm trying to control the speed of my CNC mill spindle.
It runs on Mach 3 software. PWM to 10v DC conerter diagram. Thanks Ian. If it is for very high frequency 10meg hertz plus work then some times only a correct replacement will work satisfactory, but this is rare.
I am sure other folk may have other opinions, but I have found this approach works for me. Hi Trev , thanks for the info two usefull links while a search for data for a transistor very often links to datasheetcataloge.
