SLA6020

Overview

The SLA6020 is a monolithic Darlington transistor array manufactured by Sanken Electric USA Inc. It integrates three NPN and three PNP Darlington pairs within a single 12-pin SIP package. The device provides high current gain, with a typical hFE of 2000 at an output current of 3A. It supports continuous collector currents up to 5A for both polarities and withstands supply voltages of ±100V. Designed for robust switching applications, it features a thermal resistance (θj-c) of 5°C/W and operates across a junction temperature range of -40°C to +150°C.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific datasheet revision matches design requirements. Check RoHS compliance status if environmental regulations apply to the target assembly. Ensure proper thermal management solutions are integrated into the PCB layout to maintain safe operating temperatures during operation.

Selection Notes

Select this component when complementary high-current switching is required in a compact form factor. Evaluate the thermal dissipation needs based on the ambient temperature and load duty cycle. Consider the ±100V voltage rating against the system supply rails. Verify that the 12-pin SIP footprint aligns with the available board space and mounting constraints.

Part Context

This component belongs to Sanken's lineup of power transistor arrays designed for industrial and automotive applications. It serves as a bridge between low-power logic controllers and high-power loads. The Darlington configuration simplifies drive circuitry by eliminating the need for external base resistors in many standard configurations.

Replacement Considerations

Consult official cross-reference lists for parametrically equivalent parts. Verify pinout compatibility and thermal characteristics before substitution. Ensure replacement devices meet the same voltage and current specifications.
