Additional Details

The 2SD1485 typically features a high collector-emitter voltage (VCEO) rating, enabling it to withstand high voltage levels without breakdown. The high current gain (hFE) ensures that a small base current can control a large collector current. The low saturation voltage (VCE(sat)) minimizes power dissipation during switching. It's designed for switching speeds that are crucial in high-frequency applications. The device is typically packaged in a through-hole package such as TO-220, facilitating easy mounting and heat sinking. The operating temperature range generally spans from -55°C to +150°C. Proper heat sinking is often required when using this transistor at its maximum rated power. The transistor's datasheet provides detailed electrical characteristics and safe operating area (SOA) information, which are essential for designing reliable circuits. The base-emitter voltage (VBE) and collector-emitter breakdown voltage (VCEO) are important parameters for circuit design and ensuring safe operation of the transistor. It is designed for fast switching, improving efficiency in switching applications.
