TB8S-G

Bridge Rectifier Overview

The TB8S-G is a silicon bridge rectifier from Comchip Technology, rated for a maximum recurrent peak reverse voltage of 800 V and a maximum average forward output current of 1.0 A at an ambient temperature of 100°C. It features a glass passivated chip junction and operates within a junction temperature range of -55°C to +150°C. The device exhibits a typical thermal resistance of 62.5°C/W on aluminum substrates and 80°C/W on glass-epoxy substrates. It supports a peak forward surge current of 30 A under JEDEC testing conditions.

Bridge Rectifier Feature Summary

• Glass passivated chip junction construction
• Plastic material with UL flammability classification 94V-0
• High surge overload rating capability

Bridge Rectifier Applications

• Space-saving printed circuit board designs
• General purpose rectification in power supplies
• AC to DC conversion circuits

Bridge Rectifier Procurement Notes

Verify the specific datasheet revision and package configuration before ordering. Confirm that the component meets RoHS compliance requirements for your manufacturing process. Ensure the supplier provides traceable documentation matching the TB8S-G marking code. Check lead solderability standards against MIL-STD-750 Method 2026 if required by your assembly specifications.

Bridge Rectifier Selection Notes

Select this component when an 800 V blocking voltage and 1.0 A continuous current are required in a compact surface-mount format. Consider the thermal resistance values for your specific PCB substrate type during heat dissipation planning. Verify that the operating environment stays within the specified -55°C to +150°C junction temperature range for reliable performance.

Bridge Rectifier Part Context

This part belongs to the TB2S-G through TB10S-G series of silicon bridge rectifiers manufactured by Comchip Technology. The series offers varying voltage ratings from 200 V to 1000 V while maintaining a consistent 1.0 A forward current capacity. The TB8S-G specifically addresses applications requiring higher voltage isolation than lower-rated siblings in the same physical footprint.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other 800 V, 1.0 A surface-mount bridge rectifiers with identical pinout configurations. Verify that replacement parts match the 94V-0 flammability rating and glass passivation technology. Ensure thermal resistance characteristics align with the original design constraints.
