GBLA08-M3/45

Overview

The GBLA08-M3/45 is a glass-passivated single-phase bridge rectifier manufactured by Vishay General Semiconductor. It belongs to the GBL series and utilizes an inline circuit configuration within a GBL case type. The device supports a maximum repetitive peak reverse voltage of 800 V and provides a maximum average forward rectified output current of 4.0 A at a case temperature of 50 °C. Key electrical parameters include a peak forward surge current rating of 120 A, a maximum instantaneous forward voltage drop of 1.0 V at 4.0 A, and a maximum DC reverse current of 5 μA at rated blocking voltage. The operating junction temperature range extends from -55 °C to +150 °C.

Feature Summary

• Glass passivation provides mechanical strength and protects against external physical damage
• Molding compound meets UL 94 V-0 flammability rating for safety compliance
• Terminals are matte tin plated and solderable per J-STD-002 standards
• Halogen-free construction with RoHS compliance for environmental safety

Applications

• AC/DC bridge full wave rectification in monitor systems
• Power supply circuits for TV sets and printers
• Switching mode power supplies (SMPS) and adapters
• Audio equipment and home appliances

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the M3 suffix indicates halogen-free, RoHS-compliant material categorization. Ensure the ordering code matches the specific package quantity requirements. Validate datasheet revision dates to ensure alignment with current manufacturing specifications. Request official documentation to confirm compliance with regional regulatory standards before finalizing procurement.

Selection Notes

Select this component based on the required 800 V reverse voltage rating and 4.0 A continuous current capacity. Evaluate thermal management requirements using the specified thermal resistance values for heat-sink or PCB mounting configurations. Consider the 120 A surge current capability for applications with high inrush currents. Verify that the GBL package dimensions fit the available printed circuit board space. Ensure the operating temperature range aligns with the intended environmental conditions.

Part Context

This device is part of the GBLAxx series of glass-passivated bridge rectifiers. Vishay designates it as End of Life, recommending the GBL08E series as the alternative device. The M3 suffix denotes halogen-free and RoHS-compliant materials. The /45 package code specifies tube delivery. This product falls under Vishay's general-purpose diode and rectifier portfolio.

Replacement Considerations

The GBL08E series is the manufacturer-recommended alternative device. Verify pinout compatibility and electrical parameter equivalence before substitution. Confirm that the replacement meets the same UL recognition file number E54214 requirements.
