SG2004J-883B

Overview

The SG2004J-883B is a high-reliability NPN Darlington transistor array manufactured by Microchip Technology. It features seven independent driver channels within a single package, designed for robust switching applications in demanding environments. The component utilizes a CDIP-16 ceramic dual in-line package with through-hole mounting to ensure mechanical stability and thermal performance. Key electrical specifications include a maximum collector-emitter voltage of 95 V and a continuous collector current of 500 mA per channel. The device maintains a minimum DC current gain (hFE) of 1000, facilitating efficient control of higher load currents with minimal input drive. It operates reliably across an extended temperature range from -55°C to +125°C, meeting stringent military and aerospace standards.

Feature Summary

• Seven-channel NPN Darlington configuration for multi-load switching
• High current gain ensures low input drive requirements
• Ceramic dual in-line package provides superior environmental sealing
• Extended temperature rating supports harsh operational conditions

Applications

• Aerospace and defense relay driving circuits
• Military-grade industrial motor control systems
• High-reliability power supply output stages
• Avionics interface and isolation modules

Procurement Notes

Verify the specific suffix J-883B against the official Microchip datasheet to confirm radiation hardness and screening levels. Confirm that the CDIP-16 package dimensions match your PCB footprint requirements. Ensure that the supplier provides traceability documentation required for high-reliability procurement processes. Check for any product change notifications that may affect pinout or electrical characteristics before finalizing orders.

Selection Notes

Select this component when multiple isolated switching outputs are required in a compact form factor. The high hFE minimizes base current demand from logic controllers. Verify that the 95V voltage rating exceeds the peak load voltage in your circuit design. Consider the thermal dissipation capabilities of the CDIP-16 package relative to the total power loss of all active channels during continuous operation.

Part Context

This part belongs to Microchip's SG series of high-reliability semiconductors, specifically designed for space and military applications. The SG2004J-883B complements other discrete and integrated solutions in the portfolio by offering multi-channel integration without compromising individual channel performance. It serves as a critical interface component between low-power control logic and high-power loads in mission-critical systems.

Replacement Considerations

Direct replacements must match the CDIP-16 package, 7-channel NPN Darlington topology, and 95V/500mA ratings. Verify equivalent hFE and operating temperature ranges. Consult Microchip for qualified alternate sources within the same reliability class.
