DB156G

Bridge Rectifier Overview

The GeneSiC Semiconductor DB156G is a single-phase glass passivated silicon bridge rectifier designed for through-hole mounting. It features a molded plastic case with plated terminals solderable per MIL-STD-202, Method 208. The device supports a maximum average forward rectified current of 1.5 A and offers a repetitive peak reverse voltage of 800 V. Key electrical parameters include a maximum instantaneous forward voltage drop of 1.1 V at 1.5 A, a peak forward surge current capability of 50 A, and a typical junction capacitance of 14 pF. The component operates within a temperature range of -55 °C to +150 °C.

Bridge Rectifier Feature Summary

• Glass passivated silicon construction provides reliable low-cost performance
• Ideal for automated printed circuit board insertion
• High surge current capability for robust operation

Bridge Rectifier Applications

• Printed circuit board power supply circuits
• General purpose AC to DC rectification
• Low to medium power electronic equipment

Bridge Rectifier Procurement Notes

Verify the manufacturer designation carefully, as some distributors may list Navitas Semiconductor due to corporate acquisitions, while official datasheets cite GeneSiC Semiconductor. Confirm the specific package type is DB and that terminal plating meets MIL-STD-202 requirements. Ensure the ordering suffix matches the required voltage rating, as the DB156G specifically denotes the 800V variant within the DB155G-DB157G series.

Bridge Rectifier Selection Notes

Select the DB156G when an 800 V repetitive peak reverse voltage is required alongside a 1.5 A continuous forward current. This component is suitable for applications needing high surge tolerance up to 50 A. Consider the thermal resistance of 36 °C/W and derate current by 20% if used with capacitive loads. The DB package allows for any mounting position, offering flexibility in PCB layout design compared to fixed orientation components.

Bridge Rectifier Part Context

The DB156G belongs to the DB155G through DB157G family of single-phase bridge rectifiers. These devices share identical mechanical dimensions and electrical characteristics except for their voltage ratings. The series utilizes a consistent molded plastic technique and glass passivation process, ensuring uniform reliability across the 600 V to 1000 V range. This standardization simplifies inventory management for designs requiring different voltage margins.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 1.5 A current rating, 800 V reverse voltage, and DB package footprint. Verify that alternative bridge rectifiers maintain comparable surge current capabilities and thermal resistance values to ensure equivalent performance in existing circuit layouts.
