As a very common MOS tube, the N-channel MOS tube is composed of a P-type substrate and two high-concentration N-diffusion regions, which is called an N-channel MOS tube. When the tube is turned on, an N-type conductive channel is formed between the two high-concentration N-diffusion regions. In this issue, Hottech introduces a common N-channel MOS tube HKTG90N03, which can be used in motor drive circuits and chargers.
