FZT605TA

The FZT605TA is a high-voltage NPN Darlington transistor manufactured by Diodes Incorporated. It features a collector-emitter breakdown voltage (VCEO) of 120V and a continuous collector current rating of 1.5A, with a peak pulse current capability of 4A. The device provides a minimum DC current gain (hFE) of 2000 when tested at 1A collector current and 5V VCE, making it suitable for high-gain amplification and switching applications. The saturation voltage is low, with a maximum VCE(sat) of 1.5V at 1A base current. The transition frequency (ft) is 150 MHz, allowing for moderate-speed switching. The transistor is housed in a surface-mount SOT223 package (TO-261-4, TO-261AA). It is compliant with RoHS and REACH, and features a halogen-free green molding compound. The device is rated for operation over a junction temperature range of -55°C to +150°C, with a maximum power dissipation of 2W (or 3W under certain conditions). Typical applications include driving lamps, relays, and solenoids.
