SB1040CT_T0_00001

Overview

The SB1040CT_T0_00001 is a Schottky barrier rectifier from the SB1020CT series manufactured by Panjit International Inc. It features a TO-220AB molded plastic case and provides a maximum average forward current of 10 A at a case temperature of 100°C. The device has a maximum recurrent peak reverse voltage of 40 V and a typical thermal resistance of 3.0°C/W. Electrical characteristics include a maximum forward voltage of 0.75 V at 5 A per leg, a peak forward surge current of 150 A, and an operating junction temperature range of -50 to +125°C.

Feature Summary

• Utilizes Schottky barrier technology for low forward voltage and high efficiency
• Constructed with flame retardant epoxy molding compound classified as 94V-O
• Designed for high surge capacity and low power loss applications

Applications

• Low voltage, high frequency inverters

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and compliance status. The provided datasheet indicates that suffix codes define packing methods such as tape and reel or bulk tube, alongside halogen-free or RoHS compliance levels. Confirm the exact version code matches project requirements before procurement.

Selection Notes

Select this component for circuits requiring a 40 V blocking voltage and 10 A continuous current handling capability. Ensure the application maintains the case temperature below 100°C to sustain the rated average forward current. Consider the 3.0°C/W thermal resistance for heat dissipation planning in the final assembly design.

Part Context

This part belongs to the SB1020CT~SB1060CT series of Schottky barrier rectifiers produced by Panjit International Inc. The series covers voltage ratings from 20 V to 60 V while maintaining a consistent 10 A current rating across all variants. The SB1040CT specifically addresses the 40 V requirement within this standardized product line.

Replacement Considerations

Cross-reference with other manufacturers offering 10 A, 40 V Schottky rectifiers in the TO-220AB package. Verify pinout compatibility and thermal resistance specifications to ensure equivalent performance in existing designs.
