I'm looking for the datasheet of a photodiode - TIL81, I cant really find it on the search engines. Can someone help? Thanks.

It's pretty old... Just scanned from my old TI catalog '83.

I have a 1976 TI data book that lists the specs, I have no way to scan the pages for you. Here is the maximum ratings, It NPN planar silicon phototransistor.
Collector -Base Voltage 50V
Collector-Emitter Voltage 30V
Emitter-Base Voltage 7V
Emitter-Collector Voltage 7V
Continous Collector Current 50mA
Continous Devie Dissipation at 25 degrees 250mW

Hfe typical when VCE=5V IC=1mA
If you need any other specs let me know

Another one, but not much more info. But they do list it as being used as a photo-diode or a photo-transistor.

Here is a good one. TIL81 Spec Sheets Details Diodes, Transistors, Thyristors, Triacs, Diode Array, Integrated Circuits and Semiconductors — Product Line

microtexan,
I can see why people get frustrated and turn to forums for help. I quit looking down the list when all of them started turning up parts distributors that didn't even have them. They must be in a lot of these peoples keyword lists.

I have a faded 6-page data sheet, but the questions need to be less vague than simply

, especially a first and only post.

I'll try to answer the most common questions:

Peak sensitivity 940 nm, skirts to near zero around 500 and 1100 nm, 50% points around 740 and 990.
With 100 ohm load, switching time as photodiode typ 500 ns, as phototransistor typ 8 us.
Angular sensitivity about +/- 10 degrees.
At 10 mW/cm^2, as photodiode, light current is typ 170 µA
At 5 mW/cm^2, as phototransistor with VCE=5V, typ 22 mA.
