The Toshiba 2SC1815-GR is a silicon NPN epitaxial bipolar transistor designed for audio-frequency general-purpose amplification and driver-stage amplifier applications. It provides a 50V collector-emitter voltage rating and supports up to 150mA collector current, making it suitable for low-power analog amplification and signal-processing circuits.
The GR suffix specifies the DC current-gain classification. At VCE = 6V and IC = 2mA, the GR grade provides an hFE range of 200 to 400. Its good current-gain linearity makes it well suited for audio preamplifiers, driver stages, and general small-signal amplification.
The device features a transition frequency of 80MHz, with collector output capacitance of 2.0pF typical and 3.5pF maximum. Under the specified conditions, typical noise figure is only 1dB at 1kHz, supporting low-noise analog and audio designs.
At IC = 100mA and IB = 10mA, collector-emitter saturation voltage is 0.1V typical and 0.25V maximum. Maximum collector power dissipation is 400mW, maximum junction temperature is 125°C, and the specified storage temperature range is -55°C to +125°C.
The 2SC1815-GR is housed in a standard TO-92 through-hole package, identified by Toshiba package code 2-5F1B. It is suitable for audio amplifiers, driver circuits, signal processing, and general-purpose switching and amplification applications.
