BD243CG

Application Field

The BD243CG can be used in a wide range of applications, such as switching power supplies, switching power amplifiers, linear amplifiers, intersection and distribution circuits, motor drives, and high frequency switching. It is particularly suitable for applications that require a high speed switching capability, such as low impedance, high speed drives with a wide range of frequencies.

Working Principle

The BD243CG is a bipolar junction transistor which works similar to other transistors. It has three terminals, namely the base (B), collector (C) and emitter (E). When the base current is increased, the collector current will also increase while the emitter current will decrease. This simplified working principle is known as “current amplification”. The BD243CG has a gain of 250, which means that for each 1mA of base current applied, up to 250mA of collector current is generated.

The BD243CG can be used in a wide variety of configurations. It can be used either as an amplifier in a circuit, or as a switch. As an amplifier, the BD243CG provides linear amplification of the input signal. As a switch, the BD243CG can be used to control the amount of current that flows through a circuit. The device is also able to switch rapidly, making it ideal for high-speed applications.

Conclusion

The BD243CG is a silicon epitaxial-base NPN power transistor with a high current and high speed switching capability. The device can be used in a wide range of applications, such as switching power supplies, switching power amplifiers, linear amplifiers, intersection and distribution circuits, motor drives, and high frequency switching. Its ability to amplify current and switch quickly make it ideal for applications that require a high speed switching capability.
