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. Manufactured by NXP Semiconductors, this component features a maximum collector-emitter voltage (VCEO) of 300V and a maximum collector-base voltage (VCBO) of 300V.

 

Key electrical characteristics include a continuous collector current (IC) of up to 500mA and a power dissipation (Ptot) of 680mW at 25°C ambient temperature. The transistor has a minimum static forward current transfer ratio (hFE) of 25 at 1mA and a typical hFE of 40 at 10mA and 30mA. Its transition frequency (fT) is a minimum of 50MHz at 10mA collector current and 20V collector-emitter voltage.

 

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. This transistor is noted as 'Not Recommended for New Design' in favor of parts like the ZTX457.

 

Applications include telephone dialler circuits and other high voltage switching or amplification tasks where its specific voltage and current ratings are beneficial.
