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 maximum collector-base voltage (VCBO) of 300V.

 

With a continuous collector current (IC) rating of 500mA and a power dissipation of 680mW at 25°C, this transistor is suitable for various high-voltage switching and amplification tasks. The operating and storage temperature range is from -55°C to +175°C.

 

Electrical characteristics include a collector-emitter saturation voltage (VCE(sat)) of 0.5V at 20mA/2mA and a base-emitter saturation voltage (VBE(sat)) of 0.9V under the same conditions. The static forward current transfer ratio (hFE) ranges from a minimum of 25 at 1mA to a typical 40 at 10mA and 30mA. The transition frequency (fT) is a minimum of 50MHz at 10mA/20V.

 

The MPSA42 is housed in a TO-92 compatible package, suitable for through-hole mounting. It is noted as not recommended for new designs, with ZTX457 suggested as a replacement.
