Hi All,
I'm trying to repair a PCB that has some surface mount SOT23 devices that apear to be transistors but testing them on the board are giving confusing results.
Its named FS45 but I can't find a datasheet that seems correct.
The device is used in 10 places on the PCB. In 4 cases they appear to be controling triacs and the attached picture it shows it connected to a BT136 triac with the FS45 connected to the gate leg of the BT136.
Can anyone identify the device and suggest an alternative?
Many thanks.
PS: I have...
