Overview
The MD1803DFX is a high-voltage NPN power transistor manufactured by STMicroelectronics. It is produced using Diffused Collector in Planar Technology, which adopts a new and enhanced high voltage structure. This technology ensures improved silicon efficiency and updated performance, particularly in the Horizontal Deflection stage of standard definition CRT displays. The transistor is designed to provide stable performance across varying operating temperatures and features a low base drive requirement, tighter hFE range at operating collector current, and an integrated free-wheeling diode.
