5 x Z0409ME TRIACS 4A 600V 10mA SENSITIVITY GATE. LONG TAG TO202-3 PACKAGE. GOOD VALUE 5 TRIAC's FOR ONLY £1.99 MANUFACTURED BY ST ( SGS-THOMSON MICROELECTRONICS ) THE Z04 SERIES OF TRIACS ARE SUITABLE FOR GENERAL PURPOSE AC SWITCHING APPLICATIONS. THEY CAN BE FOUND IN APPLICATIONS SUCH AS TOUCH LIGHT DIMMERS, FAN CONTROLLERS, HID LAMP IGNITERS etc. THE GATE CONTROL PIN IS SENSITIVE TO A LOW CURRENT 10mA SWITCHING SIGNAL MAKING THE DEVICE SUITABLE FOR DIRECT LOGIC LEVEL CONTROL. Low power TRIACs are used in many applications such as light dimmers, speed controls for electric fans and other electric motors, and in the modern computerized control circuits of many household small and major appliances. However, when used with inductive loads such as electric fans, care must be taken to assure that the TRIAC will turn off correctly at the end of each half-cycle of the ac power. A snubber circuit is often used to assist this turn off. Snubber circuits are also used to prevent premature triggering. For higher-powered, more-demanding loads, two SCRs in inverse parallel may be used instead of one TRIAC. Because each SCR will have an entire half-cycle of reverse polarity voltage applied to it, turn-off of the SCRs is assured, no matter what the character of the load.
