TIP31BG

TIP31BG Description

The TIP31BG from onsemi is a robust NPN bipolar junction transistor (BJT) designed for medium-power switching and amplification applications. Housed in a TO-220 package, it offers a collector-emitter breakdown voltage (Vceo) of 80V and a maximum collector current (Ic) of 3A, making it suitable for demanding industrial and consumer electronics. With a transition frequency of 3MHz, it balances speed and power efficiency, while its low Vce saturation (1.2V @ 375mA, 3A) ensures minimal power loss in switching applications. The device is RoHS3 compliant and REACH unaffected, meeting modern environmental standards.
