#159697 - the worst case is... Responding to: ???'s previous message |
... that you can assume NOTHING on what will happen with the transistor.
So you should design your circuit assuming any of the three terminals can disconnect, or short together, or have some weird connection, or any combination of these. The modes of failure are innumerable, rangig from thermal changes in the semiconductor - bulk (meltdown) or local (punchthrough), through physical disconnection (bond melted) into complete disintegration (explosion) of the transistor.
