2SC2634 is a NPN type transistor with low noise and high forward current transfer ratio.
The 2SC2634 is an NPN silicon epitaxial planar transistor intended for low‑frequency and low‑noise amplification. It is complementary to the 2SA1127 device and features a low noise voltage and a high forward current transfer ratio (hFE).
Key electrical specifications include collector‑to‑base voltage up to 5 V, collector‑to‑emitter voltage up to 4 V, maximum collector current of 200 mA, power dissipation of 400 mW, transition frequency (fT) of 200 MHz, and a typical noise voltage of 0.01 mV. Temperature‑dependent curves and other performance limits are also provided.
