GBI35B

Bridge Rectifier Overview

The Diotec Semiconductor GBI35B is a single-phase diode bridge rectifier designed for through-hole mounting. It features an average forward current (IFAV) of 35 A at a case temperature of 50°C and supports peak forward surge currents of 320 A at 50 Hz or 350 A at 60 Hz. The component has a maximum repetitive peak reverse voltage (VRRM) of 400 V, with a typical forward voltage drop below 1.1 V at 17.5 A. Operating junction temperatures range from -50°C to +150°C, and the device utilizes a GBI package.

• AC-DC conversion circuits
• General-purpose rectification in commercial equipment

Bridge Rectifier Procurement Notes

Verify the specific datasheet version directly from Diotec Semiconductor before procurement, as product specifications may be updated without notice. Confirm that the ordering suffix matches the required voltage rating, as the GBI35 series includes multiple variants with different reverse voltage capabilities. Ensure compliance with RoHS and ELV directives if applicable to your manufacturing standards.

Bridge Rectifier Selection Notes

Select the GBI35B specifically when a 400 V peak reverse voltage rating is required within the GBI35 series. Evaluate the thermal resistance parameters against your heat dissipation strategy, noting the distinct thermal resistances for junction-to-case and junction-to-ambient configurations. Ensure the circuit design accommodates the specified surge current limits during startup or fault conditions.

Bridge Rectifier Part Context

The GBI35B belongs to the GBI35A through GBI35M family of single-phase bridge rectifiers manufactured by Diotec Semiconductor. This series shares a common physical footprint and current handling capability but varies primarily in its maximum repetitive peak reverse voltage ratings. The GBI35B specifically addresses applications requiring a 400 V blocking capability.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering GBI package single-phase bridge rectifiers rated for 35 A and 400 V. Verify mechanical dimensions, pinout configuration, and thermal characteristics to ensure compatibility with existing PCB layouts and cooling solutions.
