MPSA42 Description

Short technical summary and product information.

The MPSA42 is an NPN silicon planar high voltage transistor designed for applications requiring high voltage capability. It offers a maximum collector-emitter voltage (VCEO) of 300V and a continuous collector current (IC) of 500mA.

 

Key electrical characteristics include a minimum DC current gain (hFE) of 25 at 1mA and 10V, and a typical hFE of 40 at 10mA and 10V. The transition frequency (fT) is 50MHz at 10mA and 20V. The collector-emitter saturation voltage (VCE(sat)) is a maximum of 0.5V at 20mA collector current and 2mA base current.

 

This transistor is housed in a TO-92-3 package, suitable for through-hole mounting. It operates over a wide temperature range from -55°C to +150°C.

 

Applications include telephone dialler circuits and other high voltage switching or amplification tasks.
