ULN2805A - Brand New STMicroelectronics Transistors (BJT) - Arrays
-
Description
The ULN2805A is an electronic component model belonging to the category of Transistors (BJT) - Arrays. It is a versatile component that features eight darlington transistors with common emitters and integral suppression diodes for inductive loads. The darlington transistors have a peak load current rating of 600mA (500mA continuous) and can withstand at least 50V in the offstate. The outputs of the ULN2805A can be paralleled for higher current capability. It comes in a convenient 18-lead plastic DIP package.
Specifications and Features
- Eight darlington transistors with common emitters
