Hi, I'm new to this site and to electronics in general. I need some help if anyone can.
I have this IC with the markings 'TPD•5C
1014S' on it. I've tried everything I can think of, but can't find any info (or datasheet). Please help. It has 5-pins, no continuity from any one pin to the next. Although when using the diode checker selection on my multimeter, I get some Vf readings (between 1.26 & 1.6 volts or so). I can post them if it will help. This isn't super important, I'm mostly just curious and really enjoy learning electronics as a hobby. Completely self taught, still have a LOT to learn. Thanks for the help.

Looks like a Teccor device, resembles a Mosfet version with 2 current detection pins.
Max.
Any Chance you'd know where to find a datasheet? If not, what are it uses & do u know the pinout? Please excuse my lack of knowledge/experience, I just started growing my interest in electronics very recently.

Where does it come from?
Im not 100% certain, but i believe I removed it from the main airbag sensor assembly module from an old 95' Toyota Camry I used to own. I'm a very 'hands on' learning type of person, I find it a lot easier to get in and actually work with things rather than study and read. However, with electronics, it's made 'datasheet pdf' an almost permanent suffix on my Google search bar. Lol.

Sry, it didn't show my last comment posted till I already posted the next. Apologies.

This is not your actual device but is a mosfet with temperature sensing: https://www.infineon.com/dgdl/Infin...n.pdf?fileId=db3a3043405f2978014071c7a5c61ff2

On that device, pin 5 (+) to pin 3 or tab (com) should read like a diode. If you charge the gate (pin 1)(say 9V + to gate and neg to pin 5 ), then pin 3 (+) should conduct to pin 5 (com).
Thank you very much! This is very helpful & much appreciated. When I get a chance to do some testing (hopefully without destroying it), I will post an update. Thanks again.

Given its source, I suspect it may be something else. Mosfets with current sense were used in motor controls and such; although, that would not preclude them being used in an airbag system.

I did happen to find a datasheet on a TPD1011S. Seems very similar appearance-wise and it's only one digit off. Jus not sure how much that one digit changes.

Sweets, your item makes more sense if the original came from an airbag circuit in a car. The "diag" circuit would be used to test if the module is good, or has faulted (or been fired) and turn on that famous "check engine" light if it detects a problem....

I'd have guessed a variant of the Toshiba brand mark - what do Teccor make?

I'd also have guessed an integrated SMPSU power device - it might be an industry standard compatible device similar to something in the Sanken range.
