GBL04

Overview

The SURGE GBL04 is a single-phase silicon bridge rectifier diode designed for general-purpose power conversion applications. It features a maximum average forward output current of 4 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes a plastic encapsulated R-PSIP-T4 through-hole package with four terminals in an inline configuration. Key electrical characteristics include a non-repetitive peak forward surge current rating of 158 A. The junction is glass passivated, and the component is constructed with an isolated case connection suitable for mounting on printed circuit boards.

Feature Summary

• Glass passivated junctions for improved reliability and stability
• Molded plastic construction utilizing epoxy materials for low cost and durability
• Isolated case design facilitating secure PCB mounting
• High surge overload capability to withstand transient current spikes

Applications

• Printed circuit board assembly for AC to DC conversion
• General purpose power supply units
• Battery charging circuits

Procurement Notes

Verify the manufacturer designation carefully, as the GBL series is widely produced by multiple semiconductor vendors including Vishay and LGE. Confirm that the specific part number corresponds to the intended 4A/400V specification and package type (R-PSIP-T4). Ensure compliance with required environmental standards such as RoHS if applicable to the final assembly. Cross-reference datasheets from authorized distributors to confirm current availability status and lead times before placing orders.

Selection Notes

Select this component when a 4 A continuous current rating and 400 V reverse voltage blocking capability are required for single-phase rectification. The through-hole R-PSIP-T4 package is suitable for applications requiring robust mechanical mounting. Ensure the operating ambient temperature remains within the specified limits to maintain the rated current capacity. Verify that the surge current requirements of the application do not exceed the 158 A non-repetitive peak rating.

Part Context

The GBL series represents a family of silicon bridge rectifiers commonly used in low to medium power electronic devices. These components are characterized by their compact molded plastic packages and high surge current ratings. The GBL04 variant specifically targets applications requiring 4 A output at voltages up to 400 V. This series is widely adopted in consumer electronics and industrial control systems due to its reliable performance and cost-effective construction.

Replacement Considerations

Compatible substitutes include the GBU404 from Comchip Technology, which offers similar electrical specifications in a comparable package. Other potential replacements within the GBL family or equivalent series should be verified against the specific current, voltage, and thermal requirements of the original design.
