Overview
The SG2821L is a high-reliability Darlington transistor array manufactured by Microchip Technology. It features an NPN configuration with seven independent channels arranged in an array. The device supports surface mount installation in a CLCC-20 package. Key electrical specifications include a maximum collector-emitter voltage (VCEO) of 95 V and a maximum DC collector current of 500 mA per channel. The minimum DC current gain (hFE) is specified at 1000. It operates within a temperature range of -55°C to +125°C and provides open collector outputs.
Feature Summary
- High-reliability construction suitable for demanding environments
- Seven-channel Darlington transistor array configuration
- Open collector output structure for flexible interfacing
Applications
- Medium current driver applications requiring high reliability
- Industrial control systems utilizing Darlington arrays
- Military or aerospace electronic circuits
Procurement Notes
Verify the specific ordering suffix and revision level directly with Microchip Technology or authorized distributors before procurement. Confirm that the CLCC-20 package variant matches the design requirements. Ensure compliance with RoHS directives as indicated in the official documentation. Request current availability status due to potential supply constraints for specialized components.
Selection Notes
Select this component when a robust, multi-channel NPN Darlington array is required for medium current switching. Verify that the 95 V VCEO rating exceeds the peak load voltage in the circuit. Ensure the PCB layout accommodates the CLCC-20 footprint and thermal dissipation needs for 500 mA operation. Compare against standard logic ICs if lower power consumption is critical.
Part Context
This part belongs to Microchip's portfolio of discrete semiconductor devices, specifically within the Darlington Transistors sub-category. It serves as a rugged alternative to standard plastic-packaged arrays, offering enhanced durability for harsh operating conditions compared to general-purpose consumer electronics components.
Replacement Considerations
Consult Microchip datasheets for direct pin-compatible alternatives within the SG series. Verify that any substitute maintains the 7-channel array topology and CLCC-20 package dimensions. Ensure equivalent VCEO and hFE ratings are met for reliable circuit performance.
