The 2SC2983 with Diacs Trigger Diode TO-252-2 (DPAK) RoHS is a bipolar transistor manufactured by Changjiang Electronics Technology Co. Ltd. It has three terminals which include an emitter, a base, and a collector. It is a NPN (negative-positive-negative) device, meaning that it provides amplification when the current flows from the emitter through the base and into the collector. It has a current rating of 900 mA and a frequency range of up to 100MHz. It is RoHS compliant, meaning that it is free of hazardous chemicals such as lead, mercury, cadmium, and hexavalent chromium. It has an insulation layer of Body Weave Diace, Perfect Anti_Moisture and Anti-Static. It is also designed to be compatible with a variety of electronic equipment from different manufacturers.
