SG2823L-DESC

Overview

The SG2823L-DESC is a high-reliability Darlington transistor array manufactured by Microchip Technology. It features seven NPN transistors configured in an open-collector output arrangement, designed for medium-current driving applications. The device is housed in a 20-pin Ceramic Leadless Chip Carrier (CLCC) package suitable for surface mount installation. Key electrical specifications include a maximum collector-emitter voltage of 95 V and a maximum DC collector current of 500 mA per channel. The unit exhibits a minimum DC current gain of 1000 and operates within a temperature range of -55°C to +125°C.

Feature Summary

• High-reliability construction suitable for demanding environments
• Seven-channel Darlington configuration for efficient signal amplification
• Open-collector outputs providing flexible load interfacing capabilities

Applications

• Industrial control systems requiring robust switching
• Military and aerospace electronic assemblies
• High-reliability data acquisition hardware

Procurement Notes

Verify the specific suffix requirements with the manufacturer prior to ordering, as designator codes may indicate distinct qualification levels or testing standards. Confirm that the CLCC-20 footprint matches the target PCB layout constraints. Ensure thermal management strategies align with the specified operating temperature limits during system integration.

Selection Notes

Select this component when a multi-channel, high-gain switching solution is required in a hermetically sealed or high-reliability package. Compare against standard plastic packages if environmental exposure is minimal. Verify that the 95V voltage rating and 500mA current capacity meet the specific load requirements of the application circuit without exceeding absolute maximum ratings.

Part Context

This part belongs to Microchip's line of high-reliability discrete semiconductors, often utilized in sectors where standard commercial components are insufficient. The SG2823 series provides a compact alternative to discrete transistor networks, reducing board space and assembly complexity while maintaining consistent performance characteristics across multiple channels.

Replacement Considerations

Consult official substitution guides for equivalent Darlington arrays from the same manufacturer family. Verify pin compatibility and thermal resistance values before integrating alternative sources into existing designs.
