SLA6022

Overview

The SLA6022 is a monolithic integrated circuit containing complementary NPN and PNP Darlington transistor pairs. Designed for high-current switching applications, it features an internal equivalent circuit with three resistors: R1 (2.5kΩ), R2 (2.5kΩ), and R3 (200Ω). The device supports a collector current of up to 5A and operates within a supply voltage range of 80V to 100V depending on polarity. It utilizes a 12-pin SIP package with a fin for thermal management, offering a junction-to-case thermal resistance of 5°C/W. The component is rated for a maximum junction temperature of 150°C.

Feature Summary

• Integrated complementary NPN and PNP Darlington pairs for bridge or H-configuration driving
• High output current capability suitable for heavy loads
• Built-in base resistors simplify external drive circuit requirements
• Thermal fin design facilitates heat dissipation in through-hole mounting

Applications

• Three-phase motor drives
• General-purpose power switching
• Relay driver circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation before procurement. Suffixes may indicate variations in packaging, screening levels, or environmental compliance. Confirm that the component status aligns with project lifecycle requirements, as availability may be restricted.

Selection Notes

Evaluate the thermal performance based on the expected load current and ambient conditions. Ensure the drive circuit can provide sufficient base current to saturate the Darlington pairs at the required collector currents. Verify that the package dimensions and pinout match the target PCB footprint.

Part Context
