K1100E70 Description

Short technical summary and product information.

The Littelfuse Inc. K1100E70 is a bidirectional SIDAC, a silicon bilateral voltage-triggered switch. It is designed to switch on when the applied voltage exceeds its breakover voltage point, then conduct through a negative resistance region to a low on-state voltage. Conduction is maintained until the current drops below the minimum holding current.

This SIDAC has a breakover voltage range of 104V to 118V and an on-state RMS current rating of 1A at 50/60Hz and temperatures below 125°C. It features glass-passivated junctions for ruggedness and dependability in harsh environments. The operating temperature range is -40°C to 125°C (TJ).

The K1100E70 is supplied in a TO-92 package (TO-226-2, TO-92-2 (TO-226AC)). Its applications include high voltage power supplies, natural gas igniters, high-pressure sodium lamps, and Xenon flash ignition.

Key electrical specifications include a peak on-state voltage of 1.5V at 1A for Kxxx0y types and 3.0V for Kxxx2y types, a dynamic holding current up to 150mA, and a repetitive peak off-state current of 5μA. It also has a critical rate of rise of on-state current of 150 A/μs and a critical rate of rise of off-state voltage of 1500 V/μs.
