    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.

    *DISCALIMER*

    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.

    with apologies to Jace Everett:

    When you came in, the light went out
    And OC facet filled up with doubt
    I don't know exactly what you did,
    but before the night is through
    I wanna swap dead diodes with you

    I'm the kind to sit up in her room
    Aligning knife edge and PBS cube
    I don't know what you did to it,
    but I know this much is true:
    I wanna swap dead diodes with you

    When you came in, the light went out
    Electrostatic discharge, or it took a clout
    I don't know what you did to it, but I know this much is true:
    I wanna swap dead diodes with you
    I wanna swap blue dead diodes with you

    -J.
