ignition switch Littelfuse K2400GHU featuring silicon bilateral voltage triggered thyristor technology
Product Description
The K2xx0yHU series High Energy Unidirectional SIDACs are designed for gas ignition applications requiring high current pulse capability, particularly at low repetition rates. These solid-state switches offer voltage activation with peak voltage levels ranging from 190 to 260 Volts. They are available in both DO-15 leaded and DO-214AA surface mount packages. The SIDAC functions as a silicon bilateral voltage-triggered Thyristor switch, transitioning to a low on-state voltage through a negative resistance region. Conduction persists until the current is interrupted or falls below the device's minimum holding current. Key advantages include AC circuit orientation, a triggering voltage range of 190-260V, 280A pulse current capability, and RoHS compliance. Applications include high voltage power supplies, natural gas igniters, and Xenon flash ignition.
