Overview
The SG2823J is a high-reliability Darlington transistor array manufactured by Microchip Technology. It integrates eight NPN Darlington pairs with internal suppression diodes, designed for driving lamps, relays, and solenoids in severe environments. The device features open collector outputs with breakdown voltages up to 95V and maximum DC collector currents of 600mA. It operates within an ambient temperature range of -55°C to +125°C and utilizes an 18-pin ceramic dual in-line (CDIP) package.
Feature Summary
- Integrates eight NPN Darlington pairs with internal clamping diodes for inductive load protection
- Compatible with DTL, TTL, PMOS, or CMOS drive signals
- Hermetic ceramic packaging suitable for military and aerospace applications
Applications
- Military systems requiring severe environment operation
- Aerospace control circuits
- Industrial relay and solenoid drivers
Procurement Notes
Verify the specific ordering suffix and manufacturer history, as this component originated from Microsemi Corporation before its acquisition by Microchip Technology. Confirm that the hermetic ceramic CDIP-18 package meets the environmental requirements for the intended deployment. Request official datasheets to validate pinout compatibility and electrical specifications against current design needs.
Selection Notes
Select the SG2823J when high voltage isolation and medium current switching are required for inductive loads. Ensure the input logic levels match the available drive signals, as the device supports multiple logic families. Consider the thermal management capabilities of the ceramic package if operating near the upper temperature limit of 125°C.
Part Context
The SG2823J belongs to the SG2800 series of high-voltage medium-current driver arrays. This series provides optimized designs for interfacing with various digital logic families while offering robust performance in harsh conditions. The device serves as a bridge between low-power control logic and higher-power actuators like relays and solenoids.
Replacement Considerations
Cross-reference numbers include 5962-86058012A and 5962-86058012. Verify functional equivalence regarding pinout and electrical ratings before substitution.
