Abstract :
We have identified and explained a unique ESD breakdown mechanism of high voltage 80V LDMOS structures for very fast CDM transients. The device was protected against observed damage by placing a zener across the gate and source which prevents the observed voltage build up at the gate of the LDMOS.
