Working on a 2014 Fiat 500 after airbag deployment. Got most everything fixed but most of the warning lights on the instrument cluster do not work. Traced it down to a blown part (diode?, rectifier?, transistor? etc) on the cluster board, but can't figure out what the actual name of the part is. Can't find any schematics online. I did locate another good cluster and the blown part is labeled as: .Dt0

But can't find anything online about it. Any ideas (and the best place to buy). THANKS!

 

This is a Nexperia PUMD10 Transistor pair (with resistors integrated into the package).

THANKS so much! I've got them ordered already and will let u know how it goes. I'm tempted to ask how u knew this stuff, but I guess their's no substitute for experience.

 

Not a problem. Happy to help.

To the latter, we don't have to rely on IC Master volumes much anymore; but, back in the day, you HAD to have them to have a hope of finding obscure devices for repairs. Now days, there are plenty of online references to chase those top markings down, and ferret-out data sheets and suppliers for nearly anything.

In today's climate of "just replace it", however, it's more likely that you will--given some persistence--find a reference for a particularly old component; only to discover that it has been obsoleted and the distribution pipelines are dry. That's when that datasheet (and an applicable schematic) comes in handy; because, in most cases, you can replace a rare device with discrete components in order to achieve the same function.

There's a lot of satisfaction to be had when you can do that, in the field, under the gun, and with only what you have in your vehicle inventory.
