The transistor is encapsulated in a RO-CSP package with four pins.

Application Field

MPS6513_D74Z is capable of meeting the requirements ofsmall area, low power and high current amplifier, switching andsensing applications. It is widely used in fields like digital outputs,analog switch and biasing applications, as well as digital signalprocessing and feature control. It is suitable for applications likeinterfacing with CMOS/TTL logic, low level switching, analogswitching, input/output protection and pulse generation. Its smallpackage size makes it suitable for portable electronics, automobileelectronics and handheld devices.

Working Principle

MPS6513_D74Z is a PNP transistor, which means its base is connected to its emitter, while the emitter is connected to the ground. When a small current is applied to the base, it allows a large current to flow through the collector and emitter, resulting in the desired amplified current flow. The current gain of the transistor is determined by the level of current applied to the base. When the current applied is lower than the original level, the current passing through the collector and emitter decreases, leading to a diminished amplification. To maintain a constant flow, the base current needs to be adjusted.

Conclusion

MPS6513_D74Z is a PNP silicon epitaxial transistor with high DC current gain and a voltage drop of 1.5V at 4mA. It is used in small area, low power and high current amplifier, switching and sensing applications, like digital outputs, analog switch and biasing applications, digital signal processing and feature control. The principle of its operation is based on the fact that when a small current is applied to the base, it allows a large current to flow through the collector and emitter, resulting in amplified current flows.
