SB3045CT_T0_00001

Overview

The SB3045CT_T0_00001 is a Schottky Barrier Rectifier from the SB3020CT series manufactured by Panjit International Inc. It features a TO-220AB molded plastic case and provides a maximum average forward current of 30 A at a case temperature of 75°C. The device offers a maximum repetitive peak reverse voltage of 45 V and a maximum DC blocking voltage of 45 V. Electrical characteristics include a typical thermal resistance (RθJC) of 1.5°C/W, a maximum forward voltage of 0.75 V at 15 A per leg, and a peak forward surge current capability of 275 A for an 8.3 ms single half sine-wave. The operating junction temperature range extends from -55°C to +150°C.

Feature Summary

• Utilizes Schottky barrier technology to achieve low power loss and high efficiency in rectification applications.
• Constructed with flame retardant epoxy molding compound classified as UL 94V-O for enhanced safety.
• Designed with high surge capacity and low forward voltage to support high current capabilities.

Applications

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

Procurement Notes

Verify the specific ordering suffix T0_00001 against official documentation to confirm packing configuration. The source indicates that the 'T' code corresponds to Tape and Ammo Box packaging, while other codes denote different formats such as Tape and Reel or Bulk Packing. Confirm compliance requirements including RoHS 2011/65/EU and IEC61249 Halogen Free standards directly with the manufacturer before procurement.

Selection Notes

Select this component when a 45 V reverse voltage rating and 30 A continuous current are required for power conversion tasks. Ensure the application environment allows for adequate heat dissipation given the 1.5°C/W thermal resistance. Verify that the TO-220AB package fits the mechanical constraints of the target design. Consider derating the current by 20% if the load is capacitive to maintain reliable operation within specified limits.

Part Context

This part belongs to the SB3020CT series, which encompasses devices ranging from 20 V to 60 V reverse voltage ratings. All members of this series share the same 30 A current handling capability and utilize the TO-220AB package. The series is designed for general-purpose rectification where low forward voltage drop and high efficiency are critical performance factors.

Replacement Considerations

Other parts within the SB3020CT series, such as SB3040CT or SB3050CT, offer identical current ratings but differ in reverse voltage specifications. Ensure the replacement part's voltage rating meets or exceeds the circuit requirements. Verify that the physical footprint and pinout of the TO-220AB package remain compatible with the existing PCB layout.
