The FMMT449TA is an NPN silicon planar medium power transistor designed for general purpose switching and amplification applications. It offers a minimum collector-emitter breakdown voltage of 30V and a continuous collector current rating of 1A, with a peak pulse current capability of 2A. The device provides a DC current gain (hFE) ranging from 70 to 300 at 50mA, ensuring consistent performance across various operating conditions.
Key electrical characteristics include a low collector-emitter saturation voltage of 0.5V typical at 1A, and a transition frequency of 150 MHz minimum, making it suitable for medium-speed switching circuits. The transistor is housed in a compact SOT23-3 surface mount package, which is ideal for space-constrained designs. The operating junction temperature range is -55°C to 150°C.
The FMMT449TA is a complementary NPN type to the FMMT549 PNP transistor. It is RoHS3 compliant and has a moisture sensitivity level of 1, indicating no special handling requirements for moisture-sensitive assembly processes.
