The FZT649 is an NPN Bipolar Junction Transistor (BJT) manufactured by ON Semiconductor. It is designed for general purpose switching and amplification applications. Key electrical specifications include a collector-emitter voltage (Vceo) of 25V, a continuous collector current (Ic) of 3A, and a power dissipation (Pd) of 2W. The transistor offers a minimum DC current gain (hFE) of 100 at 1A collector current and 2V collector-emitter voltage, and a low collector-emitter saturation voltage (Vce(sat)) of 600mV at 3A collector current. The transition frequency (fT) is 150MHz, suitable for moderate-speed switching circuits.
The device is housed in a surface mount package, available as TO-261-4 (also known as TO-261AA) with a supplier device package of SOT-223-4. This package provides good thermal performance for the 2W power rating. The operating junction temperature range is -55°C to 150°C, allowing use in a wide variety of environments.
The FZT649 is listed as RoHS3 compliant, MSL Level 1, and REACH Unaffected, though these compliance statuses are unverified. It is commonly used in medium-power load switching, DC-DC converters, and motor driver circuits.
