Phase control thyristor ATDN4803FC350 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for SCR thyristor N4803FC350 IXYS UK Westcode, Littelfuse, OLD Part Number N1683CH35 Westcode.

Average forward on-state current ITAV4803 ampere, repetitive peak forward and reverse voltage VDRM/VRRM3500V. Phase control thyristor are designed to convert and control DC and AC currents. "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, high resistance to thermal and electric cycling, natural or forced air cooling.

The technical specifications and parameters of N4803FC350, N1683CH35 and replacement ATDN4803FC350, datasheet PDF, outline drawing and dimensions are listed below.

Our company provides a quality guarantee for thyristors of 2 years from the date of purchase. When supplying thyristors, if necessary, we provide technical passport and certificate of conformity.

Heat sinks for power disc thyristors:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

Air and water heat sinks for thyristor cooling are also available to order.

See for more information about heatsinks: "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".
