MPSA44 NPN TRANSISTOR TO-92
MPSA44 is a high voltage NPN transistor made for general purpose amplifier and switching applications. It comes in a TO-92 through-hole package, which makes it easy to use in repair work, prototype boards, and standard electronic circuits. Official manufacturer information describes MPSA44 as a high voltage NPN bipolar transistor in TO-92 package for general purpose amplifier applications.
This transistor is a practical choice for circuits that need reliable high-voltage performance in a compact through-hole body. Manufacturer datasheets list key ratings such as 400V collector-emitter voltage, 300mA continuous collector current, and around 625mW power dissipation, which makes it suitable for many control, driver, and signal-level electronic designs.
