MPSA42 NPN Transistor

Fr 500.00

MPSA42 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin


. It has a gain value of 30; this value determines the amplification capacity of the transistor normally MPSA42 will not be used for amplification due to its low gain value.


  • Bi-Polar, High Voltage NPN Transistor
