Overview
The APT2X31S20J is a Schottky discrete rectifier manufactured by Microchip Technology. It features a dual parallel configuration housed in an SOT-227-4 package with screw mount installation style. The device supports a reverse voltage of 200 V and offers a forward current rating of 30 A to 45 A depending on the specific datasheet revision. It operates within a temperature range of -55°C to +175°C.
Feature Summary
- Dual parallel internal structure for enhanced current handling capabilities
- Schottky barrier technology ensuring low forward voltage drop
- High thermal stability suitable for demanding industrial environments
Applications
- Industrial power supply systems
- DC-DC converter circuits
- Freewheeling diode applications in motor drives
Procurement Notes
Verify the specific datasheet revision when ordering, as forward current ratings may vary between 30 A and 45 A across different documentation versions. Confirm the SOT-227-4 package outline matches your chassis requirements. Ensure screw mount compatibility with your thermal management design before finalizing procurement.
Selection Notes
Select this component for applications requiring high efficiency at moderate voltages. The dual parallel configuration allows for effective current sharing. Consider the thermal resistance characteristics of the SOT-227 package when designing heat sinks. Verify that the 200 V reverse voltage rating exceeds the peak inverse voltage in your circuit.
Part Context
This part belongs to the ISOTOP family of high-voltage Schottky diodes from Microchip Technology (formerly Advanced Power Technology). These devices are designed for robust performance in power electronics. The SOT-227 package provides a reliable mechanical interface for chassis mounting in high-power density applications.
Replacement Considerations
Check for direct substitutes within the same ISOTOP series such as the APT2X61DQ120J for higher voltage requirements. Ensure any replacement maintains the dual parallel configuration and compatible SOT-227 footprint. Verify electrical parameters match or exceed the original specifications.
