Phase control thyristor ATY24A-550-06 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for SCR thyristor Y24KPA-06-06, Y24KPA Techsem. Average forward on-state current ITAV – 550 ampere, repetitive peak forward and reverse voltage VDRM/VRRM – 200-600V. Phase control thyristor are designed to convert and control DC and AC currents. Thyristor ratings: Y24KPA-06-2 (550A 200V), Y24KPA-06-4 (550A 400V), Y24KPA-06-6 (550A 600V). "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series" for thyristor cooling are also available to order. Features: press pack industry standard ceramic housing; designed for high power industrial and power transmission applications; optimized for low on-state voltage drop; matched Qrr and VT values available for series and / or parallel connections. The anode and cathode of the thyristor (polarity) are determined by the symbol on the case. Power phase control thyristors (PCT) are also called Silicon Controlled Rectifier (SCR thyristors), Capsule Type Thyristors, and are optimised to give low conduction losses and are primarily intended for applications with line frequencies up to 500Hz. Thyristors AS ENERGITM have the following features: low static and dynamic losses, high values of VDRM/VRRM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 10 to 15000 A
