The seven Darlington pairs in ULN can operate independently except the common cathode diodes that connect to their uln2003n collectors. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the uln2003zn temperatures required by lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: The product detailed below complies with the specifications published by RS Components.
RS Components Statement of conformity. A Darlington transistor also known as Darlington pair achieves very high current amplification by connecting two bipolar transistors in direct DC coupling so the current amplified by the first transistor is amplified further by the second one.
The ULN is known for its high-current, high-voltage capacity. The resultant current gain is the product of those of the two component transistors:.
