SB2040CT_T0_00001

Overview

The SB2040CT_T0_00001 is a Schottky barrier rectifier from the SB2020CT series manufactured by Panjit International Inc. It features a TO-220AB molded plastic case with solder-plated terminals. The device provides a maximum average forward current of 20 A at a case temperature of 75°C and supports a peak forward surge current of 200 A for an 8.3 ms single half sine-wave. It offers a maximum repetitive peak reverse voltage of 40 V, a maximum RMS voltage of 28 V, and a maximum DC blocking voltage of 40 V. The typical thermal resistance (RθJC) is 2°C/W, and it operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Utilizes majority carrier conduction for low power loss and high efficiency.
• Constructed with flame retardant epoxy molding compound classified as UL 94V-0.
• Designed for high surge capacity and low forward voltage characteristics.
• Complies with EU RoHS 2.0 directives and IEC 61249 green molding compound standards.

Applications

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

Procurement Notes

Verify the specific part number against official datasheets to confirm electrical ratings and package dimensions. Ensure compliance with environmental directives such as RoHS 2.0 and IEC 61249 if required by your application. Confirm that the TO-220AB package matches your thermal management and mounting requirements. Check for any product change notifications regarding material or manufacturing updates.

Selection Notes

Select this component when a 20 A continuous current rating and 40 V reverse voltage are required in a through-hole TO-220AB package. Consider the 2°C/W thermal resistance for heat dissipation calculations. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature range. Derate current by 20% if used with capacitive loads.

Part Context

This component belongs to the SB2020CT series, which includes variants with reverse voltages ranging from 20 V to 60 V. All members share the same 20 A current rating and TO-220AB mechanical structure. The series is designed for general-purpose rectification where low forward voltage drop and high efficiency are prioritized over ultra-fast switching speeds.

Replacement Considerations

Direct substitutes within the same series include SB2020CT, SB2030CT, SB2045CT, SB2050CT, and SB2060CT, provided the voltage rating meets the circuit requirements. Cross-manufacturer replacements must match the 20 A current, 40 V reverse voltage, and TO-220AB package constraints.

FAQ

What is the maximum non-repetitive surge current for the SB2040CT?

The maximum non-repetitive surge current is 200 A, measured as an 8.3 ms single half sine-wave superimposed on the rated load.

How does the SB2040CT handle capacitive loads?

For capacitive loads, the maximum average forward current must be derated by 20% to ensure safe operation within the specified thermal limits.

Is the SB2040CT lead-free?

Yes, the device is lead-free and complies with EU RoHS 2.0 directives and the IEC 61249 standard for green molding compounds.
