Product Description
Product Overview
The TOSHIBA 2SA1298 is a silicon PNP epitaxial transistor manufactured using the PCT process. It is designed for low frequency power amplifier and power switching applications. Key advantages include high DC current gain (hFE = 100 to 320), low saturation voltage (VCE (sat) = -0.4 V max), and suitability as a driver stage for small motors. It is complementary to the 2SC3265 and comes in a small package.
