Overview
The ULN2003AS16-13 is a high-voltage, high-current Darlington transistor array manufactured by Diodes Incorporated. It contains seven open-collector common-emitter pairs, each rated for a collector current of 500mA and capable of withstanding up to 50V. The device includes integrated suppression diodes for inductive load driving and features inputs compatible with 5V TTL and CMOS logic families. It is housed in a surface-mount SO-16 package (Type SM) with a maximum thickness of 1.75mm. The component operates within an ambient temperature range of -40°C to +105°C.
Feature Summary
- Seven independent Darlington pairs per package
- Integrated clamp diodes for inductive loads
- Inputs pinned opposite outputs for simplified layout
- Compatible with 5V TTL and CMOS logic
Applications
- Relay drivers
- Solenoid drivers
- DC motor drivers
- LED displays
- Filament lamps
Procurement Notes
Verify the specific ordering suffix 'S16' corresponds to the SO-16 (Type SM) package variant when sourcing. Confirm that the part status is acceptable for your design timeline, as datasheet documentation indicates this specific configuration may be Not Recommended for New Design (NRND). Ensure compliance with RoHS and Halogen-free requirements if applicable to your manufacturing standards.
Selection Notes
Select this component when interfacing 5V logic circuits with high-voltage or high-current loads requiring seven independent channels. Consider the thermal resistance characteristics of the SO-16 package for power dissipation calculations. Verify that the 500mA per channel rating meets the peak current demands of the intended loads without paralleling outputs.
Part Context
This part belongs to the ULN200xA series of Darlington arrays from Diodes Incorporated. It shares functional similarities with the ULN2002A and ULN2004A but is specifically optimized for 5V logic compatibility through its internal base resistor configuration. The series provides a versatile solution for driving various peripheral power loads directly from standard logic gates.
Replacement Considerations
Direct replacements include other ULN2003 variants such as the ULN2003AT16-13 (TSSOP-16 package) or generic industry equivalents like the SN75489 or TC78W004FTG, provided pinouts and electrical ratings are verified against the original application requirements.
