Abstract

Transient blocking with electrostatic discharge (ESD) protection to be employed with a transient blocking apparatus that has a transient blocking core with an input, an output and at least one depletion mode n-channel device interconnected with at least one depletion mode p-channel device such that a transient alters a bias voltage Vp of the p-channel device and a bias voltage Vn of the n-channel device so that these devices mutually switch off to block the transient. The apparatus uses high-voltage depletion mode devices, e.g., MOSFETs, connected before the input and/or past the output of the transient blocking core in uni-directional and bi-directional embodiments, respectively. The ESD protection unit can be of the fold-back type and is connected between the input and output of the core to protect the transient blocking apparatus by causing the core to turn the high-voltage devices back on and shunting the core when dangerously high over-current conditions are produced by ESD events.
