Latest Patents

Jonsson holds a patent for a self-igniting thyristor with a plurality of discrete, field-controlled features. This thyristor incorporates a zener diode that is integral to its design. The zener diode bridges the central junction of the thyristor, and its breakdown voltage determines the breakover voltage of the device. The unique design allows for the breakdown voltage of the zener diode to be influenced by the field geometry near the surface of the semiconductor body. Additionally, a conducting screen is arranged over the PN junction of the zener diode, separated by an insulating layer. This configuration enables the potential of the screen to influence the field geometry, thereby affecting both the breakdown voltage of the zener diode and the breakover voltage of the thyristor.
