SB30H150CT-1E3/45

Overview

The SB30H150CT-1E3/45 is a Vishay General Semiconductor Schottky diode array featuring a common cathode configuration. It provides a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 15 A per diode. The device utilizes TO-262AA (I2PAK) through-hole packaging with long leads. Key electrical characteristics include a maximum DC reverse leakage current of 10 mA at 150 V and a typical forward voltage drop of 980 mV at 15 A. The junction temperature range spans from -55°C to +175°C, supporting high-temperature operation in demanding power electronics applications.

Feature Summary

• Schottky barrier technology for low forward voltage drop and minimal switching losses
• Common cathode dual-diode configuration simplifies circuit design
• Extended junction temperature rating up to 175°C for robust thermal performance

Applications

• High-frequency DC-DC converters
• Free-wheeling rectification in motor drives
• Polarity protection circuits

Procurement Notes

Verify the specific suffix '1' against the manufacturer's official datasheet to confirm pinout and mechanical dimensions, as variations exist within the SB30H series. Confirm RoHS compliance status via the latest production documentation. Ensure the TO-262AA package footprint matches the target PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when a common cathode Schottky array is required for 150 V applications. The 15 A current rating suits moderate-to-high power conversion tasks. Consider the TO-262AA package for through-hole mounting where higher current capacity than standard TO-220 devices is needed. Evaluate thermal management needs given the 175°C junction limit.

Part Context

This part belongs to the SB30H series of high-current Schottky rectifiers from Vishay. The series offers various voltage ratings while maintaining the 30 A total current capability split across two diodes. The SB30H150CT-1E3/45 specifically targets the 150 V breakdown requirement within this family, providing a balance between voltage handling and current capacity for industrial power supplies.

Replacement Considerations

Direct substitutes may include other Vishay SB30H series variants with matching voltage ratings or equivalent Schottky arrays from other manufacturers such as STMicroelectronics or ON Semiconductor. Verify that replacement parts match the 150 V reverse voltage, 15 A per diode current, and TO-262AA package dimensions.
