SG2823J-883B

Overview

The SG2823J-883B is a high-reliability Darlington transistor array manufactured by Microchip Technology. It features seven NPN Darlington pairs configured in an array, housed in a CDIP-16 package for through-hole mounting. The device supports a maximum collector-emitter voltage of 95 V and a continuous DC collector current of 500 mA per channel. It operates within a temperature range of -55°C to +125°C and provides a minimum DC current gain (hfe) of 1000.

Feature Summary

• Seven integrated NPN Darlington transistor pairs for medium-current driving applications
• High-reliability construction suitable for demanding environments
• Open-collector output configuration for flexible interfacing

Applications

• Industrial control systems requiring isolated switching
• High-reliability logic interface circuits
• Solid-state relay driver arrays

Procurement Notes

Verify the specific suffix J against the official Microchip datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status directly with the manufacturer as regulatory details may vary by production batch. Ensure the CDIP-16 package footprint matches the target PCB design before finalizing procurement orders.

Selection Notes

Select this component when multiple independent low-side switches are required in a single package. The high current gain reduces base drive requirements compared to standard transistors. Verify that the 95 V collector-emitter voltage rating exceeds the maximum load voltage in the application circuit to prevent breakdown.

Part Context

This part belongs to Microchip's SG series of high-reliability discrete semiconductors. These components are designed for aerospace and defense markets where radiation hardness and long-term stability are critical. The SG2823J serves as a multi-channel alternative to individual discrete Darlington transistors, simplifying board layout.

Replacement Considerations

Check for direct equivalents such as the SG2024J-883B, which offers a similar Darlington array configuration but with a different pin count and package type. Ensure any substitute maintains the required 7-channel configuration and CDIP-16 compatibility if physical interchangeability is necessary.
