Product Overview
The 2SC4617 is an NPN bipolar junction transistor designed for general-purpose small-signal amplification and low-current switching. It features a 50V collector-emitter voltage rating, 150mA maximum collector current, and a DC current gain range of 120–560 at 1mA collector current. Its low output capacitance and 180MHz transition frequency make it suitable for compact analog, signal-conditioning, and interface circuits.
Packaged in a compact SOT-523 surface-mount package, the 2SC4617 is well suited to space-constrained PCB designs where small size is a priority. It can be used in signal amplification, buffering, low-current switching, and complementary transistor stages in low-power electronic circuits.
