A source of information?
http://www.electronics-radio.com/art..._numbering.php
Hard to decipher some semiconductor part numbers, these days. 1N, 2N, 3N devices are well defined but 4N and 5N and 6N parts were never? defined. Does anybody out there actually know if the old JEDEC standard was dropped, or usurped, or has it just faded into the past? I cannot find a JEDEC reference to a 6Nxxx optocoupler. |
