DB152G

Bridge Rectifier Overview

The GeneSiC Semiconductor DB152G is a single-phase, glass-passivated silicon bridge rectifier designed for general-purpose applications. It features a molded plastic case with a maximum average forward rectified current (IO) of 1.5 A and a peak forward surge current (IFSM) rating of 50 A. The device supports a repetitive peak reverse voltage (VRRM) of 100 V, corresponding to an RMS reverse voltage of 70 V and a DC blocking voltage of 100 V. Operating within a junction temperature range of -55°C to +150°C, it exhibits a typical thermal resistance (RΘJA) of 36 °C/W and a typical junction capacitance of 14 pF.

Bridge Rectifier Feature Summary

• Glass passivation provides reliable low-cost construction utilizing molded plastic technique
• High surge current capability suitable for resistive or inductive loads
• Small size and simple installation ideal for printed circuit board mounting

Bridge Rectifier Applications

• General-purpose rectification in power supply circuits
• Printed circuit board assembly requiring compact components
• Applications involving half-sine wave, 60 Hz resistive or inductive loads

Bridge Rectifier Procurement Notes

Verify the specific manufacturer source when sourcing this component, as datasheet documentation indicates distribution through third-party semiconductor suppliers rather than direct GeneSiC channels. Confirm that the received units match the DB152G marking and package dimensions specified in the official technical documentation to ensure correct electrical ratings and polarity alignment.

Bridge Rectifier Selection Notes

Select the DB152G when a 100 V reverse voltage rating and 1.5 A continuous current capacity are required for PCB-mounted bridge rectification. Ensure the application load remains within the specified thermal limits, noting that capacitive loads require a 20% current derating. Verify that the operating environment falls within the -55°C to +150°C junction temperature range for optimal performance.

Bridge Rectifier Part Context

This component belongs to the DB151G through DB154G series of single-phase bridge rectifiers from GeneSiC Semiconductor. The series shares identical mechanical dimensions and current handling capabilities, differing primarily in their voltage ratings. The DB152G specifically addresses applications requiring a 100 V blocking voltage, positioned between the lower-voltage DB151G and higher-voltage variants.

Bridge Rectifier Replacement Considerations

Compatible replacements include other DB152G parts from different manufacturers offering identical 1.5 A/100 V specifications in the DB package. Cross-referencing with DB1502 surface mount variants requires verification of pinout compatibility and thermal characteristics.
