STMICROELECTRONICS ULN2803A Bipolar Transistor Array, Darlington, NPN, 50 V, 2.25 W, 500 mA, 1000 hFE, DIP

The ULN2803A device is a 50 V, 500 mA Darlington transistor array. The device consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability.
