GBU1005

Overview

The GBU1005 is a glass passivated single-phase bridge rectifier manufactured by Taiwan Semiconductor Corporation. It features a molded plastic construction with Underwriters Laboratory Flammability Classification 94V-0 and is designed for printed circuit board mounting. The device provides an average forward rectified current of 10 Amperes at 60Hz resistive loads and supports a repetitive peak reverse voltage of 50 Volts. Key electrical parameters include a maximum non-repetitive peak forward surge current of 200 Amperes, a maximum DC forward voltage of 1.1 Volts at 10 Amperes, and a maximum DC reverse current of 5 microamperes at 25°C ambient temperature.

Procurement Notes

Verify the specific manufacturer designation when sourcing this component, as the GBU series is widely produced by multiple semiconductor vendors including Continental Device India and HORNBY. Confirm that the selected unit matches the required 50-volt rating and 10-ampere current capacity for your specific circuit design requirements before finalizing procurement.

Selection Notes

Select the GBU1005 for circuits requiring a 50-volt reverse blocking capability and 10-ampere continuous current handling in a through-hole package. Ensure the application operates within the specified thermal limits, noting that current derating may be necessary if the device is subjected to capacitive loads or elevated ambient temperatures beyond standard conditions.

Part Context

This component belongs to the GBU series of glass passivated bridge rectifiers, which covers a voltage range from 50 volts to 1000 volts while maintaining a consistent 10-ampere forward current rating across the family. The GBU1005 specifically represents the lowest voltage option in this standardized lineup, sharing identical physical dimensions and thermal characteristics with higher voltage variants like the GBU1010.

Replacement Considerations

Cross-reference with other manufacturers' GBU1005 equivalents such as those from Continental Device India or HORNBY. Verify that substitute parts maintain the same 50-volt reverse voltage, 10-ampere current rating, and GBU package footprint to ensure mechanical and electrical compatibility.
