DB35-14

Bridge Rectifier Overview

The DB35-14 is a three-phase silicon bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current rating of 35 A and a maximum repetitive peak reverse voltage of 1400 V. The device utilizes standard silicon technology with a typical forward voltage drop of 1.05 V at 17.5 A and a reverse leakage current of 10 µA at 1400 V. Designed for robust operation, it supports a junction temperature range from -50°C to +150°C. The component is housed in a DB-35 (5-pin square) base-mount package, suitable for high-power industrial applications requiring reliable three-phase rectification.

Bridge Rectifier Procurement Notes

Verify the specific datasheet version for the DB35-14 to confirm exact electrical tolerances and mechanical dimensions before integration. Ensure that the mounting surface preparation meets the manufacturer's requirements for thermal interface materials. Confirm compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference pinout diagrams with the PCB layout to prevent installation errors during production.

Bridge Rectifier Selection Notes

Select the DB35-14 when a three-phase rectifier with a 35 A continuous current capacity and 1400 V blocking voltage is required. Compare the forward voltage drop against system efficiency targets, as higher currents increase conduction losses. Evaluate the thermal resistance characteristics to ensure adequate heat sinking solutions are available for the intended operating environment. Consider the physical dimensions of the DB-35 package for enclosure space constraints.

Bridge Rectifier Part Context

The DB35 series represents Diotec Semiconductor's lineup of high-current three-phase bridge rectifiers. These components are engineered for demanding power electronics applications where reliability under high stress conditions is critical. The DB35-14 specifically addresses the need for high-voltage handling within this series, complementing lower voltage variants like the DB35-06 or DB35-12.

Bridge Rectifier Replacement Considerations

The DB35-10 is a documented similar model within the same product family, offering comparable current ratings but with a different voltage specification. Verify electrical compatibility before substitution.
