The FMMT449 is a general-purpose NPN bipolar junction transistor manufactured by On Semiconductor. It is designed for switching and amplifier applications requiring moderate voltage and current handling.
Key electrical specifications include a maximum collector-emitter voltage (Vce) of 30V, a continuous collector current (Ic) rating of 1A, and a maximum power dissipation of 500mW. The device offers a minimum DC current gain (hFE) of 100 at 500mA and 2V, with a typical transition frequency of 150 MHz. The collector-emitter saturation voltage is 1V maximum at 200mA base current and 2A collector current.
The transistor is housed in a surface mount SOT-23-3 package, which is also available as TO-236-3 and SC-59 variants. It is rated for operation over a junction temperature range of -55°C to 150°C. The component is designated as RoHS3 compliant, MSL Level 1, and REACH unaffected, though these compliance statuses are unverified and should be confirmed with the manufacturer.
