Diodes Incorporated MMST5401-7-F PNP Transistor

The MMST5401-7-F from Diodes Incorporated is a high-quality PNP (Positive-Negative-Positive) bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. This versatile component is a must-have for electronics enthusiasts and professionals alike, offering reliable performance in a compact SOT-23 package.

Key Features

• Transistor Type: PNP - The MMST5401-7-F is a PNP transistor, which means it is turned on when a small current flows through the base in the opposite direction of the emitter to collector current.
• High Voltage: It supports a collector-base voltage (VCBO) of -150V, making it suitable for circuits that require high voltage handling capabilities.
• Current Handling: The collector current (IC) rating is up to -200mA, allowing it to control a fair amount of current for a variety of applications.
• Power Dissipation: With a power dissipation of 300mW, this transistor can handle a moderate amount of power, making it ideal for small to medium power applications.
• Gain Bandwidth Product (fT): The transition frequency is at 50MHz, which is indicative of the frequency at which the transistor can effectively amplify a signal.
• Package: The SOT-23 package is known for its small footprint and is widely used in surface-mount technology, saving valuable board space without compromising performance.
