Plastic-Encapsulate Darlington Transistors
ULN2003A

Darlington Transistor (NPN)
Introduction
ULN2003A is a high voltage, high current Darlington
transistor array. Each device consists of seven NPN
Darlington pairs that can be output independently.
These Darlington pairs have common emitter poles
that support high voltage output with a common
cathode clamp diode for switching inductive loads.
The input and output of the clamp diode are relatively
fixed to simplify the layout of the printed circuit board.
The collector current of a single Darlington pair is
rated at 500mA, and parallel Darlington pairs provide
a higher current.
Each Darlington pair of ULN2003A devices has a
2.7kΩ series base resistance that works directly with
TTL or CMOS devices. This device is often used to
drive a variety of loads, such as DC engine, LED
display light, high power cache and general logic
circuits such as TTL, 5V CMOS, etc.

10.2 Notes
Electrostatic Discharge Caution
This IC may be damaged by ESD. Relevant personnel shall comply with correct installation
and use specifications to avoid ESD damage to the IC. If appropriate measures are not taken
to prevent ESD damage, the hazards caused by ESD include but are not limited to
degradation of integrated circuit performance or complete damage of integrated circuit. For
some precision integrated circuits, a very small parameter change may cause the whole
device to be inconsistent with its published specifications.
Junction-to-ambient Thermal Resistance RΘJA
Definition: The junction to ambient thermal resistance RΘJA is a metric of the thermal performance of the device's
packages. By comparing the metric of different companies on the same product package, the thermal performance
of the product can be roughly estimated in a relative sense. RΘJA is measured under the conditions specified in the
corresponding specifications. If the measurement of RΘJA of two products follows different specifications and
standards, or although the same specifications and standards are adopted, it is not tested in strict accordance with
the specifications, then the RΘJA of two products will lose the meaning of comparison. This product follows the test
specified by JEDEC in the EIA/JESD51-x series documents. RΘJA is measured in still air with TA = 25°C and
installed on a 1 in 2 FR-4 board covered with 2 ounces of copper.
Usage: Junction to ambient thermal resistance RΘJA is a parameter defined at the system level rather than on a
single device or chip. In the test of RΘJA provided in the data sheet, most of the heat generated by the operation of
the device is dissipated through the test board rather than the packaging surface of the device. In fact, the design
and layout of PCB (such as chip or pad size, internal package geometry, etc.) will significantly affect RΘJA. At this
time, any calculation of the junction temperature or thermal power consumption of the device by applying RΘJA in
the data sheet will have a very large error, so that it does not match the real performance of the device. Therefore,
RΘJA should be used as the relative comparison of product packaging thermal performance between different
companies, rather than directly using RΘJA in the data sheet in the actual calculation.
Reference Maximum Power Dissipation for Continuous Operation PD Ref
The reference maximum power dissipation for continuous operation PD Ref is not an accurate value obtained from
the actual test. It is a theoretical value obtained according to the heat dissipation capacity of packaging combined
with practical application. It is used to compare the differences of heat dissipation capacity more intuitively between
products of different companies. This value is only for estimation reference and cannot be used as an index of the
actual performance of the device for circuit design.
