uiKenkyushoThe 2SC2757 is a Bipolar Transistor BJT (Bipolar Junction Transistor) with RoHS (Restriction of Hazardous Substances) compliance, manufactured by ShikuesuiKenkyusho. It is an NPN transistor used for general purpose switching and amplification. It has a SOT-23 package, which is a small, inexpensive packaging type that packages devices in vertical form in a compact size. This allows for low profile, cost-effective designs. It has maximum collector current of 200mA, collector-emitter voltage of 40V and power dissipation of 500mW. Additionally, it has maximum collector-base voltage of 60V and maximum emitter-base voltage of 5V. It is used in various applications such as switching, amplifying, interfacing and power management.
