MMBT2222A

The MMBT2222A is a popular NPN bipolar junction transistor (BJT) manufactured by various companies, including ON Semiconductor. It is a general-purpose transistor commonly used in low-power amplification and switching applications. The MMBT2222A is a surface-mount version of the traditional TO-92 packaged 2N2222 transistor, designed for use in small-scale electronic circuits where space is a constraint.

The MMBT2222A features a maximum collector-base voltage (Vcbo) of 30V, a maximum collector-emitter voltage (Vceo) of 30V, and a maximum emitter-base voltage (Vebo) of 6V. It has a continuous collector current (Ic) rating of 600mA and a peak collector current (Icm) rating of 1A. The transistor's power dissipation is rated at 350mW, making it suitable for low-power applications. The MMBT2222A operates within a junction temperature range of -55°C to +150°C.

This transistor is commonly used in applications such as signal amplification, switching circuits, and general-purpose amplification. Its small size and low power consumption make it ideal for use in portable electronic devices, consumer electronics, and other compact applications. The MMBT2222A is often used as a replacement for the 2N2222 in surface-mount designs, offering similar electrical characteristics in a smaller package.

The MMBT2222A is typically packaged in a SOT-23 (Small-Outline Transistor) case, which is a three-lead surface-mount package. This package is widely used in modern electronic circuits due to its small size and ease of integration into printed circuit boards (PCBs). The transistor's leads are typically arranged with the emitter on the left, the base in the center, and the collector on the right when viewed from the top of the package.
