Texas InstrumentsULN2004ADDarlington BJT

With one of these NPN ULN2004AD Darlington transistors from Texas Instruments, you'll be able to process much higher current gain values within your circuit. This product's maximum continuous DC collector current is 0.5 A. It has a maximum collector emitter saturation voltage of 1.1@100mA|1.3@200mA|1.6@350mA V. 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. It has a maximum collector emitter voltage of 50 V. This Darlington transistor array has an operating temperature range of -20 °C to 70 °C.
