Additional Infomation About Product

The MMBTA42 is a small signal bipolar junction transistor (BJT) from Diotec. It is a surface-mount NPN device with a super-low current gain and low collector-emitter saturation voltage. It is mainly used in switching and amplifier circuits, and is suitable for applications that require fast switching times in small electronics such as audio amplifiers and in high-frequency digital logic circuits. The small package size of the MMBTA42 contributes to its popularity among hobbyists and with professionals.
