GBU1504-G

Overview

The GBU1504-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for general-purpose applications. It utilizes silicon epitaxial planar chips encapsulated in a GBU plastic package with four terminals. The device features an isolated case connection and meets RoHS standards. Key electrical parameters include a maximum repetitive peak reverse voltage of 400 V and a maximum average forward rectified current of 3.2 A. It supports a non-repetitive peak forward surge current of 200 A and operates within a junction temperature range from -55 °C to 150 °C.

Feature Summary

• Utilizes silicon epitaxial planar chip technology for reliable performance.
• Encapsulated in UL94-V0 rated flame retardant epoxy for safety.
• Features an isolated case connection suitable for heat sinking.

Applications

• General purpose rectification
• Low voltage high frequency inverters
• Free wheeling diode circuits

Procurement Notes

Verify the specific manufacturer source, as the GBU1504 designation is widely produced by multiple vendors including LITEON and RFE International. Confirm that the '-G' suffix specifically denotes the Comchip Technology variant and matches the required DO-201AD or GBU mechanical dimensions. Ensure compliance with RoHS directives is documented in the official datasheet provided by the supplier before procurement.

Selection Notes

Select this component when a 400 V reverse voltage rating and 3.2 A continuous current capacity are required in a flange-mountable GBU package. Consider the 150 °C maximum operating temperature for thermal management design. Verify that the 200 A surge current capability aligns with the circuit's inrush requirements. Compare mechanical footprint compatibility against existing PCB layouts.

Part Context

This part belongs to the family of single-phase bridge rectifiers used in power supply conversion. It serves as a fundamental component for converting AC input to DC output in various electronic systems. The GBU package allows for direct mounting to heatsinks, facilitating thermal dissipation in medium-power applications compared to smaller surface-mount alternatives.

Replacement Considerations

Direct substitutes include the GBU1504 from other manufacturers such as LITEON or RFE International, provided the pinout and mechanical dimensions match. Verify that alternative parts meet the same 400 V reverse voltage and 3.2 A current ratings. Ensure the replacement maintains the same RoHS compliance and operating temperature range.
