Abstract
An electrostatic discharge (ESD) protection apparatus and an integrated passive device (IPD) with capacitor(s) are provided. The ESD protection apparatus includes a transistor, an impedance, and a capacitor disposed in a redistribution layer (RDL) structure of a package. The first terminal and the second terminal of the transistor are respectively coupled to a first power rail and a second power rail of the RDL structure. A first terminal of the impedance is coupled to the first power rail. A second terminal of the impedance is coupled to a control terminal of the transistor. A first terminal of the capacitor is coupled to the second terminal of the impedance. A second terminal of the capacitor is coupled to the second power rail.
