Looking at the broken switch’s PCB, I can see that one component in the voltage input section is fully charred and basically vaporised. Comparing with an intact PCB I can glance the following data:. Fits the description, and according to the link would be marked N5 with suffixes, so N59 would fit.

APM (Anpec) – P-channel Enhancement Mode Mosfet

Anyone have a clue what transistor this may be, and what to replace it with? Here is a picture of the board click to zoom: It might be a PFET being used as a power switch or a soft-start device. Difficult to say without a schematic.

The drain goes to a coil L1 and to another cap C9. From the looks of it is likely used as a voltage regulator?

Hmm, hard to say. It could well be the control FET on a switching regulator. If so, you could look it up and see what kind of switching topology it uses A hi-res Picture would be nice, if not mandatory. Not just of the IC but of the surrounding circuit.

Here’s the datasheet for U2. On page 19 there’s a circuit that looks similar to yours. Spehro and JRE were right! I’d give one of them a try: Datasneet course it could make things worse than they are now, but I doubt it.

Spehro Pefhany k 4 I hadn’t looked at U3 yet, but it looks like it’s indeed a very similar arrangement, with U3 and Q3 both controlled by what seems to be an MCU U2 and then providing power via smoothing cap and coil datasheeh components. Unfortunately upon applying power the power LED of the switch does not light up.

It seems that more parts may be broken. I’m marking this as the answer for now.

N5 would match, but the ‘9M’ would be out of place. Unless Vishay changed their markings? These switches are about years old. I couldn’t tell you. I just had a look around, and found what seemed to be a good match.

That’s only an 8V part- seems a bit low, but then that would explain fatasheet it didn’t like 12V. Sign up or log in Sign up using Google. Sign up using Facebook.
