SDB157-TP

Bridge Rectifier Overview

The SDB157-TP is a single-phase bridge rectifier manufactured by Micro Commercial Components (MCC). It features a glass-passivated chip junction and operates with an average forward current of 1.5 A at 40°C ambient temperature. The device supports a peak repetitive reverse voltage of 1000 V and withstands a non-repetitive peak surge current of 50 A for an 8.3 ms half-sine wave. Electrical characteristics include a maximum forward voltage of 1.1 V and a reverse leakage current of 10 µA at 125°C. It utilizes an SDB-1 surface mount package, measuring approximately 10.4 mm in length, 8.51 mm in width, and 3.3 mm in height.

Bridge Rectifier Feature Summary

Bridge Rectifier Procurement Notes

Verify authenticity through authorized MCC distributors or direct purchase from the manufacturer to avoid counterfeit components. Ensure the ordering suffix matches the required packaging format, such as Tape & Reel for bulk quantities. Confirm compliance with specific environmental directives like REACH and SVHC requirements before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 1000 V reverse voltage rating and 1.5 A continuous current capacity are required in a compact surface mount footprint. Consider the thermal resistance values and derating curves if operating near maximum temperature limits. Verify that the SDB-1 package dimensions align with the target PCB solder pad layout specifications.

Bridge Rectifier Part Context

This part belongs to the SDB151 through SDB157 series, which share identical physical packages and electrical current ratings but differ in their peak repetitive reverse voltage capabilities. The SDB157-TP represents the highest voltage variant within this specific family, offering 1000 V blocking capability while maintaining the same 1.5 A average forward current specification.

Bridge Rectifier Replacement Considerations

Cross-reference with other SDB-1 package bridge rectifiers rated for 1000 V and 1.5 A. Verify pinout compatibility and thermal resistance parameters to ensure equivalent performance in the existing circuit design without requiring PCB modifications.
