The NEC 2SD743 is a silicon NPN power transistor housed in a TO-220C package. It is designed for applications such as audio frequency power amplifiers and low-speed switching circuits.
Key electrical characteristics include a maximum collector-base voltage of 100V and a collector-emitter voltage of 80V for the 2SD743 variant and 100V for the 2SD743A variant. The continuous collector current is rated at 4A, with a peak collector current of 6A. The maximum collector power dissipation is 40W at 25°C case temperature.
Thermal characteristics include a junction-to-case thermal resistance of 3.125°C/W. The device operates within a junction temperature range of -50°C to 150°C and a storage temperature range of -50°C to 150°C.
This transistor is a complement to the 2SB703/703A PNP types. Its robust design and specifications make it suitable for various power amplification and switching tasks.
