I have ups device with inverter board problem, there are some defect components, one of them is smd transistor with code N1P , I’ve searched and found equivalent number is bfr53,
which is 2Ghz wideband NPN transistor
There are about 100 devices with code N1, the 'p' probably indicates the manufacturer.
It isn't impossible its a BFR53 but I can't think of a good reason a transistor with those characteristics would be used in an inverter, it is more commonly used in cable TV distribution amplifiers. Note that some N1 coded devices are Zener diodes or voltage regulators so if you test them as transistors they will appear to be faulty.
You right, me too surprised, but it’s the same as photo on eBay which I’ve posted first, let’s assume it’s a transistor until I take real photos for you later, for this component and for the board I have
For now, it must be replaced with wideband transistor?
