MPSA42 Description

Short technical summary and product information.

The MPSA42 is a high voltage NPN silicon planar transistor manufactured by KEC. It is designed for applications requiring high voltage handling, such as telephone dialler circuits.

 

Key electrical specifications include a collector-base voltage (VCBO) and collector-emitter voltage (VCEO) of 300V. The continuous collector current (IC) is rated at 500mA, with a power dissipation of 680mW at 25°C ambient temperature. The transistor features a minimum static forward current transfer ratio (hFE) of 25 at 1mA and a transition frequency (fT) of 50MHz.

 

The MPSA42 is housed in a TO-92 compatible package, suitable for through-hole mounting. The operating and storage temperature range is from -55°C to +175°C.

 

Note: The datasheet provided is for the MPSA42 from Diodes Inc., and this part is listed as 'Not Recommended for New Design'. A recommended replacement is the ZTX457.
