The RF100BA08 is a low-current, dual-mode, low-voltage, bidirectional silicon-controlled rectifier (SCR) manufactured by JHN. It features two SCRs in one 5-pin package, allowing it to switch two circuits with one device. The device operates in either auto-trigger or voltage-triggered mode, and is ideal for applications like bidirectional motor control, current limiting, or over/under voltage protection. It can handle up to 100A of current, with a peak non-repetitive surge of 1000A for up to 20ms. The RF100BA08 is rated for operation up to 400V, and provides temperature protection through its integral junction temperature monitor. It is rated for operation up to 125° C.
