SDB155-TP

Bridge Rectifier Overview

The SDB155-TP is a single-phase bridge rectifier from the Micro Commercial Components (MCC) SDB151-SDB157 series. It features a 1.5 A average rectified forward current and a 600 V peak repetitive reverse voltage rating. The device utilizes glass passivated chip junctions for enhanced stability and is housed in an SDB-1 surface mount package. Electrical characteristics include a maximum forward voltage of 1.1 V at rated current, a reverse leakage current of 10 µA at 125°C, and a non-repetitive peak surge current of 50 A. The component operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Feature Summary

• Glass passivated chip junction provides high reliability and stable performance under varying thermal conditions.
• Surface mount SDB-1 package design facilitates automated assembly and compact circuit board integration.
• Halogen-free construction meets environmental standards with UL 94 V-0 flammability rating epoxy.

Bridge Rectifier Applications

• General-purpose AC to DC conversion in power supply circuits.
• Bridge rectification in consumer electronics and home appliances.
• DC output stages in industrial control systems requiring moderate current handling.

Bridge Rectifier Procurement Notes

Verify authenticity by purchasing exclusively from MCC or authorized distributors due to counterfeiting risks. Confirm RoHS compliance via the "TP" suffix designation. Ensure storage conditions adhere to Moisture Sensitivity Level 1 requirements. Validate part markings against official datasheet specifications before integration into production lines.

Bridge Rectifier Selection Notes

Select the SDB155-TP when a 600 V reverse voltage rating is required alongside a 1.5 A continuous current capacity. Consider the SDB-1 surface mount footprint for space-constrained designs. Evaluate thermal resistance parameters if operating near maximum temperature limits. Compare alternative voltage ratings within the SDB151-SDB157 series based on specific circuit peak inverse voltage demands.

Bridge Rectifier Part Context

The SDB155-TP belongs to the SDB151 through SDB157 family of single-phase bridge rectifiers manufactured by Micro Commercial Components. This series offers standardized electrical interfaces with varying voltage ratings from 50 V to 1000 V. All variants share identical physical dimensions and pin configurations, allowing for flexible design upgrades without altering PCB layout constraints.

Bridge Rectifier Replacement Considerations

Direct functional substitutes within the same series include SDB151, SDB152, SDB153, SDB154, SDB156, and SDB157. These parts maintain identical current ratings and package types but differ in peak repetitive reverse voltage capabilities. Verify voltage derating requirements before substituting with lower-rated variants.
