http://onsemi.com
The SMBJ12AON is designed to protect voltage sensitive
components from high voltage, high energy transients. This device has
excellent clamping capability, high surge capability, low zener
impedance and fast response time. The SMBJ12AON is ideally suited
for use in computer hard disk drives, communication systems,
automotive, numerical controls, process controls, medical equipment,
business machines, power supplies, and many other
industrial/consumer applications.
