    I would have a quick question about the TSAL6100 IR LED:


    In the absolute maximum ratings section of the data sheet, it says that this led's forwards current is 100ma. But then it also says that the peak forwards current is 200ma.

    My question is, if I am pulsing this LED at 38Khz, can I go beyond the 100 ma maximum current. Like for example 150ma?

    Thanks for all help!

    Look closely, the Datasheets usually give a time or duty cycle that can be used. Looks like 100 microseconds. That will be 3.8 :D pulses at 38kHz.

    Are you making your own 38k detector or using a standard can?

    the detector is a tsop4838....

    LOL.... that won't get far....

    if u don't mind me asking .... what's a a CAN?

    so I guess 100 ma is Max huh?

    I don't think 100ma will be enough though .... ??

    thanks for replying?
