Mullard TCA280A trigger module provides triggering of load triac at zero crossings of AC line voltage. Values shown are for triac requiring gate current of 100mA; for other triacs, values of Rd, Rg, and C1 may need to be changed. Designed for resistive loads and ON/OFF rather than propoltional control.－ TCA280A Trigger IC for Thyristors and Triacs, Mullard, London, 1975, Technical Note 19, TP1490, p 10.
