The MMBTA94 is a silicon-based, NPN, bipolar transistor with a high collector-emitter voltage and a low saturation voltage. It is manufactured by Diotec and is typically used in audio and analog circuits. The MMBTA94 has a maximum collector current rating of 500mA, and can be used as a switch, amplifier, current regulator, or to provide voltage gain. It features epitaxial construction, gold-metallized surface-mount technology, and high DC current gain. The low saturation voltage of the MMBTA94 makes it advantageous for use in low voltage circuits.
