The KTC4375 with Transistors manufactured by Changjiang is a NPN (negative-positive-negative) type transistor that has a drain current rating of 1.5 amperes (A) and operates at a maximum voltage of 30 volts (V). It is a surface-mount device (SMD) in a SOT-89-3 package, and complies with the Restriction of Hazardous Substances (RoHS) directive. It is a three-pin device, with the emitter, base, and collector in pins one, two, and three respectively. It is suitable for applications such as linear and switching regulators, audio and general amplifiers, and motor speed and temperature control. It will operate in temperatures ranging from 0°C to 125°C.
