Abstract
A method of providing a Transient Voltage Suppression (TVS) device is described utilizing a Metal Oxide Semiconductor (MOS) structure and an Insulated Gate Bipolar Transistor (IGBT) structure. The MOS based TVS devices offer reduced leakage current with reduced clamp voltages between 0.5 and 5 volts. Trench MOS based TVS device ( ) provides an enhanced gain operation, while device ( ) provides a top side drain contact. The high gain MOS based TVS devices provide increased control over clamp voltage variation.
