The MPS651, produced by Changjing Electronics Technology, is an electronic part designed with a TO-92 package and regulating bipolar transistor (BJT) in the shape of a transistor-outline integrated circuit (TO-92). This specialized transistor is intended primarily for applications such as relay driver circuits, buzzer drivers, switching power supplies, audio amplifiers, and other circuits requiring multiple amplification stages. It has a maximum power dissipation of 625mW and is rated to withstand voltage of up to 30V. This TO-92 transistor is constructed using a top-quality silicon substrate and RoHS compliant materials. It is suitable for a broad range of operations, from DC to 250MHz, which make it ideal for use in radio frequency (RF) amplification. Additionally, the MPS651 produces highly durable results due to its carefully designed construction and well-engineered components.
