Additional Details

The KTA1040D's specifications include parameters such as collector current (IC), base current (IB), and power dissipation. These values are critical for ensuring the transistor operates within its safe operating area. The transistor's characteristics are typically tested and specified at room temperature, and variations may occur at different temperatures. It is available in a standard through-hole package. The hFE (DC current gain) is an important parameter for amplifier design, indicating the transistor's ability to amplify current. The saturation voltage (VCE(sat)) is a key parameter for switching applications, indicating the voltage drop across the transistor when it is fully turned on.
