TT4M-T

Bridge Rectifier Overview

The TT4M is a standard recovery bridge rectifier manufactured by Diodes Incorporated, designed for general-purpose power supply applications. It features a TTL package with glass passivated die construction and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum repetitive peak reverse voltage (VRRM) of 1000 V and an average rectified output current (IF(AV)) of 4.0 A at 25°C. The forward voltage (VF) is typically 0.91 V at 2 A and 25°C, with a maximum leakage current (IR) of 5 µA at 1000 V reverse bias.

Bridge Rectifier Feature Summary

• Glass passivated die construction ensures reliable low-cost performance
• Suitable for printed circuit board mounting using molded plastic technique
• Lead-free finish compliant with RoHS directives and halogen/antimony free

Bridge Rectifier Applications

• General-purpose power supplies
• Adapters and chargers
• Battery chargers

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details, as the base part number may correspond to different carrier types such as reels or tubes. Confirm compliance requirements including UL recognition file E364304 and environmental standards like J-STD-020 moisture sensitivity level 1 before finalizing procurement specifications.

Bridge Rectifier Selection Notes

Select the TT4M when a 1000 V blocking capability and 4 A continuous current are required in a compact surface-mount configuration. Evaluate thermal resistance values based on whether a heatsink is utilized, as junction-to-ambient resistance varies significantly between mounted and unmounted conditions. Ensure the application does not exceed the specified peak forward surge current limits under expected fault conditions.

Bridge Rectifier Part Context

The TT4M belongs to Diodes Incorporated's family of standard recovery bridge rectifiers, offering a balance of voltage rating and current handling in a small form factor. It serves as a component for converting AC to DC in consumer electronics and industrial equipment where moderate efficiency and cost-effectiveness are prioritized over ultra-fast switching speeds.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 1000 V VRRM, 4 A IF(AV), and TTL package dimensions. Verify that alternative components maintain similar forward voltage characteristics and thermal resistance profiles to ensure equivalent performance in the existing circuit design without requiring layout modifications.
