STMicroelectronicsULN2803ADarlington BJT

This NPN ULN2803A Darlington transistor from STMicroelectronics amplifies your current and yields a much higher current gain than other transistors. This product's maximum continuous DC collector current is 0.5 A. It has a maximum collector emitter saturation voltage of 1.1@250uA@100mA|1.3@350uA@200mA|1.6@500uA@350mA V. Its maximum power dissipation is 2250 mW. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This Darlington transistor array has an operating temperature range of -20 °C to 85 °C. It has a maximum collector emitter voltage of 50 V.
