SLA6023

Overview

The SLA6023 is a high-power NPN/PNP Darlington transistor array manufactured by Sanken Electric. It integrates six complementary output pairs within a single SIP-21 package featuring an integrated heatsink fin. The device supports continuous collector currents of ±6 A and peak currents up to ±12 A, with a breakdown voltage rating of 60 V for both NPN and PNP sections. Internal base resistors are provided: 2 kΩ for the NPN channels and 80 Ω for the PNP channels. Thermal management relies on a junction-to-case thermal resistance of 5 °C/W, allowing operation at temperatures up to +150 °C.

Feature Summary

• Integrates three NPN and three PNP Darlington pairs in a unified power module
• Includes internal base resistors to simplify drive circuit design
• Features an integrated aluminum heatsink fin for efficient thermal dissipation

Applications

• Three-phase motor drive systems
• High-current switching applications
• Industrial control circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific unit matches the SLA6023 designation and SIP-21 physical dimensions. Review the datasheet for absolute maximum ratings to ensure operational parameters remain within safe limits during implementation.

Selection Notes

Evaluate the required current handling against the ±6 A continuous and ±12 A peak specifications. Ensure the drive circuit can supply sufficient base current given the internal resistor values. Consider the thermal environment and verify if the integrated fin provides adequate heat dissipation or if additional cooling measures are necessary.

Part Context

This component belongs to the SLA series of power transistor arrays produced by Sanken Electric USA Inc. These modules are designed to consolidate multiple discrete transistors into a single compact package, reducing board space and simplifying assembly for complex power electronics designs.

Replacement Considerations

The datasheet explicitly states this part is not recommended for new designs. Verify compatibility with alternative SIP-21 Darlington arrays from other manufacturers if sourcing this specific model proves difficult.
