    You really need to understand what you are trying to achieve and the components required.

    This link provides good basic information on IR communications. If you do not have to use the PHOTO diode, a better choice is an IR receiver (e.g. PNA4602M, TSOP1240, etc). These have the PHOTO diode and required conditioning circuit built-in.

    If you must use the PHOTO diode, first of good luck. Second look at an IR receiver to get an idea of what is it you need to add to the PIN diode itself.

    An example diagram is attached.
