10/02/14 - 20140291721 - Surge protection circuit for power mosfets used as active bypass diodes in photovoltaic solar power systems
A protection circuit for metal-oxide-semiconductor field-effect transistors (MOSFETs) that are used as active bypass diodes in photovoltaic solar power systems is disclosed. The protection circuit comprises, a detection circuit for detecting the start of a surge event, a switch disposed to connect the MOSFET's drain to it's gate in response...
08/09/12 - 20120199875 - Cascode scheme for improved device switching behavior
A switching device includes a low voltage normally-off transistor and a control circuit built into a common die. The device includes source, gate and drain electrodes for the transistor and one or more auxiliary electrodes. The drain electrode is on one surface of a die on which the transistor is...
01/12/12 - 20120007138 - Smoke-free esd protection structure used in integrated circuit devices
The present invention provides a smoke-free ESD protection structure used in integrated circuit devices. A JFET or n-channel MOS transistor is coupled between an I/O pad, and a transistor and diode, wherein the JFET or n-channel MOS transistor limits the current flowing through the diode and transistor to prevent the...
