The KTC4373Y with Transistors (NPN/PNP) SOT-89 RoHS manufactured by Shikues is an NPN and PNP bipolar transistor in a SOT-89 package with RoHS compliance. It has a voltage of 40V, a current of 300mA, and is designed to switch and amplify low-level signals, which makes it suitable for a wide range of applications. It has excellent linearity, high gain-bandwidth ratio, logic compatibility, and low noise characteristics. The KTC4373Y also features a high DC current gain, low collector-emitter saturation voltage, and high hfe gain at low collector-base voltage. This makes it suitable for high-speed switching and video applications.
