Product Overview

The ULN2803A from STMicroelectronics is a through hole eight darlington array in DIP package. Array contains eight darlington transistors with common emitters and integral suppression diodes for inductive loads. Each darlington features a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V in the OFF state. ULN2803A has a 2.7Kohm input resistor for 5V TTL and CMOS to simplify logic families interfacing.
  • Inputs pinned opposite to outputs to simplify board layout
  • Outputs may be paralleled for higher current capability
  • Integral suppression diodes
  • Output voltage of 50V
  • DC current gain (hFE) of 1000
  • Operating ambient temperature range from -20°C to 85°C
  • Power dissipation (Pd) is 2.25W

Applications

Power Management, Consumer Electronics, Portable Devices, Industrial
