ABS20T1M

Bridge Rectifier Overview

The ABS20T1M is a surface-mount fast recovery bridge rectifier manufactured by Diodes Incorporated. It features a SOPA-4 package with glass passivated die construction and operates within a temperature range of -55°C to +150°C. The device supports a maximum repetitive peak reverse voltage (VRRM) of 1000 V and provides a maximum average rectified output current (IF(AV)) of 2 A at a case temperature of 130°C. Key electrical characteristics include a maximum forward voltage (VF) of 1.3 V at 2 A, a maximum leakage current (IR) of 5 µA at 25°C, and a typical reverse recovery time (trr) of 500 ns.

Bridge Rectifier Feature Summary

• Glass passivated die construction for reliable low-cost performance
• Rated to withstand 1000V peak reverse voltage
• Designed specifically for surface mount technology manufacturing processes
• Lead-free finish compliant with RoHS directives and free from halogens and antimony

Bridge Rectifier Applications

• General-purpose AC to DC conversion in power supplies
• Fast recovery applications requiring high voltage blocking capability
• Automotive electronics systems meeting specific change control requirements

Bridge Rectifier Procurement Notes

Verify the component against the official Diodes Incorporated datasheet DS44740 Rev. 3-2 to confirm authenticity and specifications. Ensure that the received parts match the SOPA-4 package type and the ABS20T1M marking code. Check for compliance with RoHS and lead-free standards as documented in the manufacturer's quality definitions. Confirm the date code format matches the YWW standard specified in the ordering information.

Bridge Rectifier Selection Notes

Select this component when a 1000V rating and 2A continuous current capacity are required in a compact surface-mount form factor. Consider the 500 ns reverse recovery time for applications where switching speed is relevant but ultra-fast recovery is not critical. Evaluate thermal resistance values based on whether heatsinking is utilized, as the average current rating drops significantly without a heatsink. Verify that the operating environment falls within the specified -55°C to +150°C junction temperature range.

Bridge Rectifier Part Context

The ABS20T1M belongs to the family of surface-mount bridge rectifiers produced by Diodes Incorporated under the Zetex brand. It utilizes a molded plastic technique for cost-effective construction while maintaining high reliability through glass passivation. The SOPA-4 package allows for automated assembly, making it suitable for high-volume manufacturing environments. This part serves as a robust solution for general rectification tasks in industrial and consumer electronics.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 1000V VRRM, 2A IF(AV), SOPA-4 package, and similar trr specifications. Verify pinout compatibility and thermal characteristics before substitution. Consult the manufacturer for automotive-grade equivalents if AEC-Q100/101 qualification is required.
