The KSP44BU from ON Semiconductor is a high-voltage NPN Epitaxial Silicon Transistor. It is designed for applications requiring significant voltage handling capabilities, with a maximum collector-emitter voltage (VCEO) of 400V for the KSP44 variant and 350V for the KSP45 variant. The transistor can handle a continuous collector current (IC) of up to 300mA.
This device operates within a junction temperature range of -55°C to 150°C and has a maximum power dissipation of 625mW at 25°C ambient temperature, or 1.5W at 25°C case temperature. The thermal resistance from junction to case (RθJC) is 83.3°C/W, and junction to ambient (RθJA) is 200°C/W.
The KSP44BU is supplied in a TO-92-3 package, suitable for through-hole mounting. It offers a DC current gain (hFE) typically ranging from 50 to 200 at 10mA and 10V. The saturation voltage (Vce(sat)) is a maximum of 0.40V at 1mA collector current and 0.1mA base current, or 0.75V at 50mA collector current and 5mA base current.
This transistor is Pb-free, halogen-free, BFR-free, and RoHS compliant, making it suitable for environmentally conscious designs. Its high voltage rating and NPN configuration make it a versatile component for various switching and amplification circuits.
