1- dropped diode on concrete from workbench height= still lased
2- dropped diode on carpeting from workbench height= still lased
3- handling diode by can (NO static strap)= Still lased
4- handling diode by pins (NO Static strap)= Still lased
5- held in hand and walked around house (carpeting and non carpeted floors)= still lased
6- held solder iron on pins for >3 seconds= still lased
7- rubbed diode on my t-shirt= still lased
8- reversed polarity hookup (NO diode protection. just jerked power supply up to ~4V then back off. I did not notice the current draw)= Still lased after proper polarity connection.
I think their were a couple others, but these were the most impressive.

As i said before, none of this is Scientific. just simple "everyday" poor handling procedures and what their likely outcome would be. Obviously i am not suggesting to everyone to throw safe handling practices out and to ignore proper static protocol. i was just pretty damn impressed how resilient these things really are.
I thought that if i looked at these 445's wrong, they would pop. But i guess not.
