SB1645FCT_T0_00001

Overview

The SB1645FCT_T0_00001 is a Schottky barrier rectifier from the SB1620CT to SB1660CT series manufactured by Panjit International Inc. It features a TO-220AB molded plastic package with axial leads. The device provides a maximum repetitive peak reverse voltage of 45 V and supports a maximum average forward current of 16 A at a case temperature of 75°C. Electrical characteristics include a maximum forward voltage of 0.75 V at 8 A per leg and a typical thermal resistance of 2°C/W. The component operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Utilizes Schottky barrier technology for low power loss and high efficiency operation
• Constructed with flame retardant epoxy molding compound meeting UL 94V-O flammability classification
• Designed for high surge capacity and low forward voltage drop
• Manufactured using halogen-free green molding compound compliant with IEC61249 standards

Applications

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

Procurement Notes

Verify the specific suffix FCT against official documentation to confirm packaging orientation and type. The provided datasheet references T/R (Tape and Reel) codes but does not explicitly define the FCT variant. Confirm terminal solderability per MIL-STD-750 Method 2026 and ensure compliance with EU RoHS 2011/65/EU directives during sourcing.

Selection Notes

Select this component for applications requiring a 45 V blocking voltage and 16 A continuous current capability in a through-hole configuration. Consider the 0.75 V forward voltage drop at 8 A for thermal management calculations. Ensure the operating environment stays within the specified -55°C to +150°C junction temperature range and derate current by 20% for capacitive loads.

Part Context

This part belongs to the SB1620CT through SB1660CT series of Isolation Schottky Barrier Rectifiers. The series covers voltage ratings from 20 V to 60 V while maintaining a consistent 16 A current rating. All variants share the same TO-220AB mechanical package and general electrical characteristics, differing primarily in their maximum recurrent peak reverse voltage specifications.

Replacement Considerations

Parts within the SB1620CT to SB1660CT series are parameter equivalent regarding current and package. Verify that substitute components match the 45 V reverse voltage requirement and the TO-220AB footprint. Cross-reference thermal resistance and forward voltage specifications to ensure compatibility with existing circuit designs.
