CBR10-J040

Bridge Rectifier Overview

The Central Semiconductor CBR10-J040 is a silicon single-phase full-wave bridge rectifier designed for general-purpose high-current applications. It features a peak repetitive reverse voltage of 400 V and an average forward current rating of 10 A at a case temperature of 80°C, or 5.0 A at 30°C. The device supports a peak forward surge current of 150 A and operates within a junction temperature range of -65 to +150°C. Electrical characteristics include a maximum reverse leakage current of 10 µA at rated voltage and a forward voltage drop of 1.2 V at 5.0 A. The component utilizes the CASE CM mechanical outline.

Bridge Rectifier Feature Summary

• Single-phase silicon construction for full-wave rectification
• High thermal stability with a junction temperature range up to +150°C
• Robust surge overload capability for transient protection

Bridge Rectifier Applications

• General purpose power supply circuits
• High current DC conversion systems
• Industrial rectifier modules

Bridge Rectifier Procurement Notes

Verify availability status as the CBR10-J040 has been transitioned to End of Life (EOL) status per Product Discontinuation Notice PDN01002. Last purchase orders were effective six months from the notice date, with final shipments occurring twelve months after issuance. Confirm if surplus inventory remains available through authorized distributors before initiating procurement processes.

Bridge Rectifier Selection Notes

Select this component when a 400 V blocking voltage is required for 10 A continuous operation in standard bridge configurations. Ensure thermal management allows the case temperature to remain below 80°C to maintain the full 10 A rating; otherwise, derate to 5.0 A if operating at lower case temperatures like 30°C. Verify that the CASE CM package fits the intended PCB layout or heat sink mounting constraints.

Bridge Rectifier Part Context

This part belongs to the CBR10-J010 series, which covers voltage ratings from 100 V to 1000 V. All members share identical current ratings, thermal characteristics, and physical packaging. The J040 variant specifically provides the 400 V rating within this standardized family, allowing for consistent design practices across different voltage requirements.

Bridge Rectifier Replacement Considerations

The official replacement specified by Central Semiconductor is the CBR10-J100. This substitute shares the same 10 A current rating and CASE CM package but offers a higher 1000 V reverse voltage rating. Designers should verify that the increased voltage rating does not impact other circuit parameters.
