Product Overview
The 2SC1815M is an NPN silicon bipolar junction transistor (BJT) designed for audio-frequency amplification and general-purpose driver stages. It features a 50V collector-emitter voltage rating, 150mA maximum collector current, low-noise characteristics, and good DC current gain linearity. These characteristics make it well suited to small-signal analog and audio circuits.
Packaged in a compact SOT-23 surface-mount package, the 2SC1815M supports space-efficient amplifier and signal-processing designs. Its 80MHz transition frequency, multiple hFE gain classifications, and low-noise performance make it suitable for preamplifier, signal conditioning, and low-current driver applications.
