Overview
The SG2824J-883B is a high-reliability NPN Darlington transistor array manufactured by Microchip Technology. It features seven internal channels configured as medium-current drivers with open-collector outputs. The device supports a maximum collector-emitter voltage of 95 V and delivers a peak DC collector current of 500 mA per channel. Designed for robust performance, it operates within an extended temperature range from -55°C to +125°C. The component utilizes a hermetically sealed ceramic dual in-line package (CDIP) with 18 pins, ensuring durability in demanding environments.
Feature Summary
- High-reliability construction suitable for critical applications
- Integrated Darlington pairs with built-in protection components
- Hermetic ceramic packaging for environmental resilience
Applications
- Industrial control systems requiring isolated switching
- Military and aerospace relay driver circuits
- High-voltage load driving in harsh environments
Procurement Notes
This component is classified as a factory special order item. Availability is not maintained in standard commercial stock. Verification of current manufacturing status, specific delivery timelines, and official ordering requirements must be obtained directly from the manufacturer or authorized distributors before procurement planning.
Selection Notes
Select this part when a hermetically sealed, high-voltage Darlington array is required for NPN switching applications. Ensure the design accommodates the CDIP-18 through-hole footprint and that the 95V voltage rating aligns with the load requirements. Verify thermal management capabilities for continuous 500 mA operation at elevated temperatures up to 125°C.
Part Context
The SG2824J-883B belongs to the SG28xx series of high-reliability linear and discrete components produced by Microchip Technology. This series is engineered for defense, aerospace, and industrial sectors where long-term stability and radiation hardness are prioritized over cost efficiency. The '883B' suffix typically denotes compliance with MIL-PRF-38534 standards for hybrid microcircuits.
Replacement Considerations
Direct replacements include the SG2823L-883B, which shares similar electrical characteristics but differs in package type (CLCC vs. CDIP). Cross-reference with other SG28xx variants only if pinout compatibility and hermetic sealing requirements can be met.
