Hi,
Once I ordered some bright white LEDs from Jameco, which
were not static sensitive (no warning notice). I ordered another
type, N-94C6256, from another source and they came in a static
shielding bag with a warning!!!!! There is no information about
these. Why are these LEDs static sensitive?

Thanks in advance, Brad

Tip for your old computer (reduce discard pollution too):

If you can't sell your old computer, don't throw it away. Use it to backup
your software by transferring files/folders from your new computer or laptop
to it. I transferred my Windows folder and other stuff to my old computer
using "PC Link", which I downloaded from www.simtel.net (cool site).

Because they are semiconductor devices;they have a junction that can be
damaged by overvoltage just like any other diode.

FYI,static charges can vary from 30 volts to several *thousand* volts,with
high instantaneous currents.That's how they destroy semis.

LEDs are just diodes with low reverse breakdown V.

Static discharges can weaken semis,and cause failure days,months
later,too,not just immediately.
