KSP42TA Description

Short technical summary and product information.

The KSP42TA from ON Semiconductor is an NPN epitaxial silicon transistor. It features a maximum collector-emitter voltage (VCEO) of 300V and a continuous collector current (IC) of up to 500mA. The device has a maximum power dissipation (PC) of 625mW and an operating junction temperature up to 150°C.

 

This transistor is housed in a TO-92-3 package, suitable for through-hole mounting. It offers a DC current gain (hFE) of 40 minimum at 30mA collector current and 10V collector-emitter voltage. The saturation voltage (VCE(sat)) is 500mV maximum at 2mA base current and 20mA collector current, and the base-emitter saturation voltage (VBE(sat)) is 0.9V maximum under the same conditions.

 

The KSP42TA is Pb-free and halogen-free, complying with RoHS standards. Its frequency response is characterized by a current gain bandwidth product (fT) of 50MHz at 10mA collector current and 20V collector-emitter voltage. This makes it suitable for various switching and amplification applications where high voltage is required.
