The MOC306XM and MOC316XM components consist of a GaAs infrared emission diode that is optically connected to a monolithic silicon detector, which assumes the function of a bilateral triac driver. They are for use with a triac in the interface of logic to devices powered by 115/240-VAC lines, such as solid-state relays, industrial controls, motors, solenoids and consumer devices etc. . Simplifies the logical control of 115/240 VAC current . Zero-voltage transition to minimise conducted and radiated noise . 600 V repetitive peak off-state voltage . Superior static dv/dt . 600 V/s (MOC306xM) . 1000 V/s (MOC316xM) . Safety and official approvals UL1577, 4,170 VACRMS for 1 minute DIN EN/IEC60747.5.5
