GBL4G

Overview

The GBL4G is a glass passivated single-phase bridge rectifier diode manufactured by SURGE. It features a maximum average forward rectified output current of 4.0 amperes and a maximum repetitive peak reverse voltage of 400 volts. The device utilizes a plastic encapsulated package with four terminals in an inline configuration, suitable for through-hole mounting. Key electrical characteristics include a typical non-repetitive peak forward surge current capability of 158 amperes and a maximum DC blocking voltage of 280 volts. The component operates within a junction temperature range from -65 °C to +150 °C, ensuring reliability in general-purpose AC-to-DC full-wave rectification applications.

Procurement Notes

Verify the manufacturer designation as SURGE or Surge Components when sourcing this component. Confirm that the part number matches the specific GBL4G variant intended for your circuit design. Ensure compliance with relevant safety standards such as UL recognition if required for your final product assembly. Check datasheet revisions for any updates to mechanical dimensions or thermal ratings before finalizing procurement orders.

Selection Notes

Select the GBL4G when a 4A continuous current rating and 400V reverse voltage withstand are required for single-phase rectification. Consider its through-hole packaging for PCB designs utilizing standard drilling patterns. Evaluate the thermal management requirements based on the specified operating temperature range and case temperature limits. Compare leakage current specifications against alternative bridge rectifiers if low standby power consumption is critical for the application.

Part Context

The GBL4G belongs to the GBL series of single-phase bridge rectifiers, which are widely used in consumer electronics and industrial control systems. This series typically offers various voltage ratings ranging from 50V to 1000V while maintaining a consistent 4A current capacity. The GBL package style is recognized for its compact form factor and high reliability, making it a standard choice for general-purpose power conversion tasks in mass-produced electronic devices.

Replacement Considerations

Compatible substitutes include the GBL4005 from other manufacturers, provided they meet the same 4A current and 400V voltage specifications. Verify pinout compatibility and physical dimensions to ensure direct replacement without PCB modifications. Check for equivalent surge current ratings and thermal characteristics to maintain system performance integrity.
