Quote:Someone mention it's just a fancy name for a 15-16V zener.
No.
These are protection devices not regulating (as in voltage regulator) devices.
For a start, once the rated voltage is exceeded, they become a virtual short circuit until the voltage drops down again, they won't regulate voltage like a Zener diode.
They are designed to handle spikes on supply rails, control lines and signal lines, not extended overvoltage events, that's why it's gone pop in your rig.
A lot, not all, can be put in circuit any way round, try that with a Zener.
