I have a 12 volt regulator. Want to put some type of zener clamp on the output of the 12 volt regulator for overvoltage protection. Seems most standard zener diodes individually do not have the current rating to trip the fuse (the 0.5 amp self-resetting fuse trips at 1 amp). I have also looked at TVS type diodes but they do not have a continuous current specification. Do you have any suggestions for my application?

We can suggest NIS5132 ,it contains circuits to monitor the input voltage, output voltage, output current and die temperature.

The current limit circuit uses a SENSEFET along with a reference and amplifier to control the peak current in the device.
