摘要：
The present invention relates an electrostatic discharge (ESD) protection device that is applied to a mixed voltage circuit assembly. The device comprises a RC controlled circuit subassembly and a field transistor, which the RC controlled circuit is coupled with the mixed voltage circuit assembly to substantially control the ESD protection device to be ON or OFF. The field transistor is coupled between a first power supply and a second power supply of said mixed voltage circuit assembly, which is off on the condition of a normal operating condition and is conducting as an ESD event occurred.
