DB35-08

Bridge Rectifier Overview

The DB35-08 is a three-phase bridge rectifier manufactured by Diotec Semiconductor. It features a standard silicon construction with a maximum repetitive peak reverse voltage of 800 V and an average rectified output current of 35 A. The device utilizes a DB-35 package, which is a five-terminal square form factor designed for base mounting. Electrical characteristics include a forward voltage drop of 1.05 V at 17.5 A and a maximum reverse leakage current of 10 µA at the rated voltage. The component operates within a junction temperature range of -50°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Diotec Semiconductor or authorized distributors before procurement. Confirm that the DB-35 mechanical dimensions match the target PCB or chassis layout requirements. Ensure thermal interface materials are compatible with the base-mounting style for optimal heat dissipation during operation.

Bridge Rectifier Selection Notes

Select this component when a 35 A current rating and 800 V blocking voltage are required for three-phase applications. Consider the DB-35 package constraints regarding board space and mounting hardware availability. Evaluate thermal resistance parameters against the expected ambient temperature and cooling method to ensure the junction temperature remains within the specified operational limits.

Bridge Rectifier Part Context

The DB35-08 belongs to the DB35 series of three-phase bridge rectifiers from Diotec Semiconductor. This series typically includes variants with different voltage ratings, such as the DB35-06 (600 V) and DB35-12 (1200 V), sharing the same 35 A current rating and physical package. These components are designed for high-current industrial environments requiring reliable three-phase rectification.

Bridge Rectifier Replacement Considerations

Cross-reference with other manufacturers offering 35 A, 800 V three-phase bridges in a DB-35 equivalent package. Verify pinout compatibility and thermal performance metrics before substitution.
