TT8T08-13

Bridge Rectifier Overview

The TT8T08-13 is an 8A standard recovery bridge rectifier manufactured by Diodes Incorporated in a TTL package. It features a maximum repetitive peak reverse voltage (VRRM) of 800V and a DC blocking voltage of 800V. The device supports an average rectified output current of 8A at +25°C, with a maximum forward voltage of 1.1V at 4A. Reverse leakage current is limited to 5µA at rated voltage and +25°C, increasing to 500µA at +125°C. The typical reverse-recovery time is 300ns, with a maximum of 500ns. Thermal resistance without a heatsink is 69°C/W junction-to-ambient.

Bridge Rectifier Feature Summary

• Lead-free finish and RoHS compliant manufacturing
• Halogen and antimony free green device

Bridge Rectifier Applications

• General purpose AC to DC conversion circuits
• Power supply bridge rectification
• Battery charging applications

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix '-13' corresponds to the reel packing quantity of 1500 units as documented in the official datasheet. Confirm that the TTL package dimensions and lead finish specifications match the design requirements before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when an 800V rating and 8A continuous current capacity are required for standard recovery applications. Ensure thermal management strategies account for the 69°C/W junction-to-ambient thermal resistance if operating without a heatsink. Verify compatibility with the TTL package footprint during PCB layout.

Bridge Rectifier Part Context

This part belongs to the TT8T06/TT8T08 series of 8A standard recovery bridge rectifiers. The TT8T06 variant shares identical mechanical and electrical characteristics except for a reduced maximum repetitive peak reverse voltage of 600V compared to the 800V rating of the TT8T08.

Bridge Rectifier Replacement Considerations

The TT8T06-13 serves as a direct substitute if the circuit design only requires a 600V reverse voltage rating instead of 800V. Both parts share the same 8A current rating, TTL package, and electrical performance parameters.
