Help identifying grab bag component

[sloMoses]

I am very new at electronics. I found this website from Dave Jones' very enthusiastic videos on Youtube. I appreciate his enthusiasm and passion for the subject.

All I have is a breadboard, an Innova 3320 digital auto-ranging VOM and a cheap analog VOM to see analog meter sweeps when checking capacitors.

I bought a grab bag of components from the internet. There were some binary counters, BJT transistors, some logic gate ICs, some LEDs and some SMT ICs. There were some pink, three lead components in there, too. I figured out that they are IR phototransistors. There were some LED looking things in there, too. I figured out that they are IR LEDs.

There is another component that I haven't been able to figure out. Picture attached. I did some tests on this mystery component, much like I did with the pink phototransitors and IR LEDs. But, this mystery component is challenging me.

Currently I'm thinking that it is possibly some type of IR reactive p-channel FET (are there such things?). The voltage drops and A --> C resistance constant makes me think it is not a BJT phototransistor.

I didn't want to assume or guess anything, lest the magic smoke biloweth.

Anyone have any ideas? The following picture shows what I have tested so far.

Looks like an IR receiver module. It will detect an IR carrier typically at 36, 38 or 40 kHz.

There are two common pinouts... Out / Gnd / Vcc and Out / Vcc / Gnd.

I suspect that one is Out / Gnd / Vcc.

It just looks like an IR receiver module to me

The datasheet below shows a 22k pullup resistor on pins 'A' and 'C' so this might be likely

Perfect. Thanks for the help.

I have one of these too which I scavenged from a toy. My understanding is that it responds to a particular frequency by grounding the source through the output? So if I connect to 5v source and gnd, what am I looking for on the output pin to know the correct frequency was detected? A change from 5v to 0v? The signal that triggers it seems to be from a particular IR LED that is PWM to a set frequency, so the remote is only1 function (to trigger it or not). I guess you can't read the pulses or could you encode something on top of the signal depending on the on/off pulses?

Looking at the data sheet listed above it has an inverted logic level output. You will see a string of pulses on the output that correspond to the encoding  sent by the IR remote. 0 when there is an IR signal present.
