SG2823L

Overview

The SG2823L-883B is a high-reliability Darlington transistor array manufactured by Microchip Technology. It features seven NPN transistors configured in an array format, housed in a CLCC-20 surface-mount package. The device supports a maximum collector-emitter voltage (VCEO) of 95 V and a maximum DC collector current of 500 mA per channel. Designed for medium-current applications, it operates within a specified temperature range starting at -40°C. This component is classified under Darlington transistors and adheres to specific military-grade reliability standards indicated by the suffix.

Feature Summary

• High-reliability construction suitable for demanding environments
• Integrated Darlington configuration for high gain and drive capability
• Surface-mount packaging for automated assembly compatibility

Applications

• Medium-current switching circuits
• Relay driver interfaces
• Industrial control systems requiring high-reliability components

Procurement Notes

Verify the complete part number including the -883B suffix, as this indicates specific military or aerospace qualification levels distinct from commercial variants. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability for high-reliability parts may vary. Ensure the ordering documentation explicitly references the CLCC-20 package type to avoid substitution errors with other form factors.

Selection Notes

Select this component when a multi-channel high-gain switching solution is required in a compact surface-mount footprint. The 500 mA current rating and 95 V voltage rating define the operational limits for load driving. Consider the thermal dissipation characteristics of the CLCC-20 package during PCB layout to ensure reliable operation within the specified temperature range.

Part Context

This part belongs to Microchip's portfolio of high-reliability analog and discrete components. The SG2823 series typically denotes Darlington arrays designed for robust performance. The specific model integrates multiple transistor pairs into a single unit, reducing board space compared to discrete implementations while maintaining signal integrity for critical applications.

Replacement Considerations

Direct replacements must match the Darlington array topology, NPN polarity, and CLCC-20 package dimensions. Verify that any substitute meets the same VCEO and collector current specifications. Cross-reference with other manufacturers' high-reliability Darlington arrays if Microchip supply is constrained, ensuring pinout compatibility.
