Folks,Looked through numerous datasheets in the 100-200mW power range fromSanyo, Sony, OSI, Ondax and so on ... nada. My experience when callingis that there is no further info available.So, does anyone know what the typical capacitance of an IR laser diodein that power range is? A SPICE model would be even better. Reason I askis that we have to pulse-modulate the heck out of one, pretty muchredline it in terms of what it can give.-- Regards, Joerg

Hmmmm. Wouldn't that be 20:1? Or did you mean 450 Ohms?

Oops, sorry, 20:1. You could use 450ohms but sometimes that's too low, for example for tapping the collector on an RF stage.
