2N3490

The 2N3490 is a PNP power bipolar junction transistor manufactured by Microchip Technology. It is designed for high-power switching and amplification applications requiring a stud mount package. Key electrical specifications include a collector-emitter breakdown voltage (VCEO) of 60V, a continuous collector current (IC) rating of 7A, and a maximum power dissipation (PD) of 115W. The device operates over a junction temperature range of -65°C to 200°C. The transistor is housed in a TO-61 (also known as TO-211MA, TO-210AC) stud mount package, which facilitates efficient heat sinking in power circuits. The stud mount configuration allows for secure mechanical attachment and thermal management in industrial and military-grade equipment. As a PNP device, it is suitable for use in complementary push-pull stages, power inverters, and motor control circuits where high current and voltage handling are required. The 2N3490 is RoHS3 compliant and REACH unaffected, though these compliance statuses are unverified. It is recommended to consult the manufacturer for the latest compliance documentation.
