GBU1502-G

Overview

The GBU1502-G is a single-phase bridge rectifier manufactured by Comchip Technology, designed for general-purpose power supply applications. It utilizes glass passivated junction technology to ensure high reliability and stability under varying thermal conditions. The component features a robust GBU-4 through-hole package, facilitating secure mounting on printed circuit boards. Key electrical specifications include a maximum average forward rectified current of 15 A and a repetitive peak reverse voltage rating of 200 V. The device supports a maximum non-repetitive surge current of 350 A and operates within a temperature range of -55°C to +150°C junction temperature.

Feature Summary

• Glass passivated junction construction provides enhanced environmental resistance and long-term stability.
• High surge current capability allows effective handling of transient overload conditions during startup or fault events.
• Standardized GBU-4 through-hole footprint ensures compatibility with existing PCB layouts and automated assembly processes.

Applications

• AC-to-DC converter circuits in consumer electronics
• Power supply units requiring reliable bridge rectification
• General-purpose DC power distribution systems

Procurement Notes

Verify the specific suffix and marking codes against the official Comchip Technology datasheet to confirm the exact voltage and current ratings. Ensure that the procurement channel provides authentic components with traceable documentation. Check for RoHS compliance status if required by your manufacturing standards. Confirm lead times and packaging formats directly with authorized distributors, as availability may vary by region.

Selection Notes

Select the GBU1502-G when a 15 A continuous current and 200 V reverse voltage rating are required in a through-hole configuration. Consider the GBU series for its balance of current capacity and physical size. Evaluate the forward voltage drop and thermal dissipation requirements to ensure adequate heat sinking. Compare alternative packages like GBJ or GBPC if higher current or different mounting styles are needed.

Part Context

The GBU1502-G belongs to Comchip Technology's GBU series of glass passivated bridge rectifiers. This series is characterized by high current ratings and standardized through-hole packaging suitable for industrial and commercial applications. The GBU-4 package offers a compact form factor while maintaining robust mechanical strength for solder pin termination.

Replacement Considerations

Direct replacements must match the 15 A current, 200 V reverse voltage, and GBU-4 package dimensions. Verify that substitute components maintain equivalent surge current ratings and thermal characteristics. Cross-reference part numbers from other manufacturers offering identical electrical specifications and pin configurations to ensure functional interchangeability without redesigning the PCB.
