ABSTRACT:
An electrostatic discharge (ESD) protection circuit includes two stages. A first stage is operatively coupled to a metal bonding pad. This first stage is an npn transistor having a low resistance fusible element which has a fast response time. A second stage is operatively coupled in series to the first stage. The second stage provides a high-resistance path to protect the npn transistor after the fusible element has fused to into a high resistance voltage path. In addition, a semiconductor device having internal circuitry protected by this two stage ESD protection circuit is provided. The ESD protection circuit is operatively coupled between the bonding pad which is located external to the semiconductor device and the internal circuitry.
