MUN2238T1G is a single, pre-biased, bipolar junction transistor (BJT), manufactured by ON Semiconductor. It is a complementary PNP-NPN-type BJT specifically designed to operate in a low-voltage environment. It features a high breakdown voltage, high gain, and low RON. The MUN2238T1G also offers excellent switching characteristics, making it ideal for a variety of industrial and consumer applications.

Application Field

The MUN2238T1G is particularly well suited to applications such as:

• Switch mode power supplies (SMPS)
• DC to DC converters
• High efficiency motor drives
• High speed switching circuits
• Displays/lighting controls
• High voltage power amplifiers
• Portable communication devises
• Automotive circuits

Due to its low RON and high gain, the MUN2238T1G is also used in a wide range of general purpose circuits and can serve as the active component in analog controllers, motion control systems, and embedded applications.

Working Principle

Bipolar junction transistors (BJTs) are semiconductor devices made of two P-type and one N-type silicon junctions. In the MUN2238T1G, the PNP-NPN structure allows for current to flow in two directions and is an example of ‘active mode’ operation. When current flows through the emitter-base terminal of the PNP device, it creates a forward bias, charged holes move through the junction and into the collector, providing the transistor with its gain. Conversely, the NPN device experiences the inverse biased voltage, charged electrons move from the collector towards the base, and a current is drawn from the collector to the emitter. This phenomenon creates a negative gain.

In a single, pre-biased, PNP-NPN device, the opposite operating mechanisms also take place. When the bipolar junction transistor is connected to a signal source, such as a transistor, the PNP and NPN sides are driven in opposite directions of conduction. The voltage drop across the biasing resistor in the base, sets the output bias of the transistor. Due to this mechanism, the MUN2238T1G can handle the greater output power and reduce losses across the load.

Due to its fast switching speed and low voltage, the MUN2238T1G can operate equally well in either PNP or NPN mode. This makes it highly suitable for applications that require a bipolar junction transistor to be connected to a signal source, such as transistor amplifiers and power supplies.

Conclusion

The MUN2238T1G is a single, pre-biased BJT designed to operate in a low voltage environment. It is particularly well suited to a wide range of applications, such as switchmode power supplies, DC-DC converters, high efficiency motor drives, and portable communication devises. Thanks to its fast switching speed and low voltage operation, the MUN2238T1G is also capable of handling high output power and can be used in a variety of analog controllers, motion control systems, and embedded applications.
