The Littelfuse Inc. K1100G is a silicon bilateral voltage-triggered switch, commonly known as a SIDAC. It is designed to switch on when the applied voltage exceeds its breakover voltage point, then conducts through a negative resistance region to a low on-state voltage. Conduction is maintained until the current drops below the holding current threshold.
This SIDAC series offers a breakover voltage range from 79V to 330V, with the K1100G specifically rated for 104V to 118V. It has an on-state RMS current of 1A and a peak non-repetitive surge current capability of 20A. The component features glass-passivated junctions for enhanced reliability and ruggedness, making it suitable for harsh environments.
Applications for this series include high voltage power supplies, natural gas igniters, high-pressure sodium lamps, and Xenon flash ignition systems. The K1100G is supplied in a DO-15 axial package, suitable for through-hole mounting.
Key electrical specifications include a dynamic holding current of up to 150mA, a switching resistance of 100Ω, and a critical rate of rise of on-state current (di/dt) of 150 A/μs. The operating junction temperature range is -40°C to 125°C.
