Abstract
A power control switch assembly. The assembly may include a thyristor device, where the thyristor device includes a first device terminal, a second device terminal, and a gate terminal> The assembly may include a negative temperature coefficient (NTC) device, electrically coupled to the gate terminal of the thyristor device on a first end, and electrically coupled to the first device terminal of the thyristor device on a second end, wherein the NTC device is thermally coupled to the thyristor device.
Claims3
A thyristor device assembly, comprising:
- a thyristor device comprising a first device terminal, a second device terminal, and a gate terminal;
- a housing, disposed around the thyristor device;
- a lead frame, disposed in electrical contact with the thyristor device and extending outside of the housing, the lead frame comprising a gate lead and a first terminal lead, electrically coupled to the gate terminal and the first device terminal of the thyristor device, respectively;
- and
- a negative temperature coefficient (NTC) device disposed outside the housing, the NTC device being electrically coupled to the gate terminal of the thyristor device on a first end, and being electrically coupled to the first terminal of the thyristor device on a second end;
- wherein the NTC device is disposed in thermal contact with a second terminal lead of the lead frame, the second terminal lead connected to the second device terminal.
