I have a SOT23-3 component marked CB RF (dash above F) as shown in the following images:
I thoroughly searched both the web and a number of SMD code databases for information but I haven't been able to come up with anything.
Can you help me to identify the component?
I am assuming it is a switching mosfet as the PCB I'm repairing is a switch mode power supply and I've seen these switching mosfet's blow up before. You can see the component and surrounding it is blackened. I am still learning electronics so forgive me if I'm missing something obvious.
