I've been looking at several datasheets for triac SSRs, for example the AQH-2213 here: **broken link removed**
I'm confused why the 10mA trigger LED current is listed as a "maximum" value and not a "minimum". If 10mA is actually a maximum value, why does the recommended operating condition show a forward current of 20mA which is obviously exceeded this maximum value.
I guess I would expect the 10mA to be a minimum, the 20mA to be recommended or typical, and the 50mA as an absolute maximum.
Am I looking at this incorrectly? All SSR datasheets seem to list it as a maximum value. Confused as to why.
