Overview
The SG2803J-JAN is a high-reliability NPN Darlington transistor array manufactured by Microchip Technology. It integrates eight Darlington pairs within an 18-pin ceramic dual in-line package (CDIP-18). The device supports through-hole mounting and operates across an ambient temperature range of -55°C to +125°C. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 50 V, a maximum DC collector current of 500 mA, and a minimum DC current gain (hfe) of 1000. The output configuration utilizes open-collector terminals.
Feature Summary
- High-reliability construction designed for severe environments
- Hermetic ceramic packaging suitable for military and aerospace applications
- Compatibility with DTL, TTL, PMOS, and CMOS drive signals
Applications
- Military systems requiring MIL-STD-883 compliance
- Aerospace control circuits
- Industrial driver arrays for lamps, relays, and solenoids
Procurement Notes
Verify the specific JAN suffix requirements against MIL-M38510/14108BVA standards before procurement. Confirm that the hermetic CDIP-18 package meets environmental constraints. Ensure compatibility with existing drive signal logic levels. Validate radiation data availability if operating in space environments. Check for any recent process change notifications affecting lead finish or assembly sites.
Selection Notes
Select this component when high current switching capability is required alongside robust environmental tolerance. The 500 mA per pair rating suits medium-current load driving tasks. Verify that the 50 V breakdown voltage aligns with the inductive load suppression needs. Consider the 18-pin footprint for PCB layout constraints. Ensure the open-collector output structure matches the downstream circuit design requirements.
Part Context
This part belongs to the SG2800 series of high-voltage medium-current driver arrays. The JAN suffix indicates compliance with Military Standard MIL-M38510/14108BVA. It shares architectural similarities with non-military variants like the SG2803J but differs in reliability processing and qualification standards. The series provides multiple input configurations for versatile interfacing options.
Replacement Considerations
The SG2803J serves as the commercial equivalent. The JAN2803J is the direct military standard counterpart under MIL-M38510/14108BVA. Verify pinout compatibility before substitution. Ensure replacement parts meet the same hermetic sealing and radiation hardness requirements if applicable.
