MPSW45G

Single Bipolar Transistors Overview

The MPSW45G is an NPN Darlington transistor manufactured by onsemi, housed in a TO-92 (TO-226) through-hole package. It features a maximum collector-emitter voltage of 40 V and a continuous collector current rating of 1 A. The device exhibits a high DC current gain of at least 25,000 at 200 mA and 5 V. Key electrical parameters include a transition frequency of 100 MHz, a maximum power dissipation of 1 W, and a collector cutoff current of 100 nA. The saturation voltage is specified at 1.5 V under conditions of 2 mA base current and 1 A collector current.
