SB2040FCT_T0_00001

Overview

The SB2040FCT_T0_00001 is a Schottky barrier rectifier from the SB2020FCT series manufactured by Panjit International Inc. It features a maximum average forward current of 20 A and a maximum repetitive peak reverse voltage of 40 V. The device utilizes an ITO-220AB full molded plastic case with solder-plated terminals compliant with MIL-STD-750 Method 2026. Electrical characteristics include a maximum forward voltage of 0.75 V at 10 A per leg, a peak forward surge current of 200 A, and a typical thermal resistance of 2 °C/W per diode. Operating junction temperature ranges from -55 to +150 °C.

Feature Summary

• Low power loss and high efficiency due to low forward voltage and majority carrier conduction.
• High surge capacity suitable for demanding transient conditions.
• Constructed with flame retardant epoxy molding compound classified as UL 94V-O.
• Lead-free product compliant with EU RoHS 2011/65/EU directive and halogen-free green molding compound.

Applications

• Low voltage, high frequency inverters
• Free wheeling applications
• Polarity protection circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type and environmental compliance status. The provided datasheet indicates that suffix codes define packing methods such as Tape and Reel or Bulk, alongside Halogen-Free or RoHS designations. Confirm terminal solderability requirements and derating curves for capacitive loads prior to final procurement decisions.

Selection Notes

Select this component for applications requiring high current handling with minimal forward voltage drop. Ensure the operating environment stays within the specified junction temperature range of -55 to +150 °C. Consider the 200 A surge current rating for transient protection needs. Verify that the ITO-220AB package dimensions fit the intended PCB layout and thermal management strategy.

Part Context

This part belongs to the SB2020FCT series of Schottky barrier rectifiers designed for general-purpose rectification in power supply circuits. The series offers various voltage ratings from 20 V to 60 V while maintaining a consistent 20 A current capability. The FCT designation typically refers to the specific lead frame and molding compound configuration used in the ITO-220AB package style.

Replacement Considerations

Cross-reference electrical parameters such as forward voltage, reverse leakage current, and thermal resistance when evaluating substitutes. Ensure any replacement device supports the same ITO-220AB or compatible mechanical footprint. Verify that alternative components meet the same UL flammability classification and environmental directives.
