DBLS207G

Bridge Rectifier Overview

The DBLS207G is a single-phase bridge rectifier diode manufactured by Taiwan Semiconductor Corporation. It utilizes silicon technology and features a glass-passivated junction for enhanced reliability. The component is rated for a maximum average forward rectified current of 2 A and a repetitive peak reverse voltage of 1000 V. It employs a low-profile surface-mount package, specifically the DBLS configuration with four pins, designed for efficient thermal dissipation and compact board space utilization in power supply applications.

Bridge Rectifier Feature Summary

• Glass passivation provides mechanical strength and protects against external physical stress
• Low profile surface mount design facilitates automated assembly processes
• High surge current capability ensures robustness during transient load conditions

Bridge Rectifier Applications

• General purpose AC to DC conversion in power supplies
• Battery chargers requiring high reverse voltage blocking
• Adapters and inverters utilizing surface mount technology

Bridge Rectifier Procurement Notes

Verify the specific suffix codes on the ordering information to confirm compliance with RoHS directives and halogen-free status. Ensure the selected variant matches the required pin configuration and thermal characteristics for the intended PCB layout. Cross-reference datasheets from authorized distributors to confirm availability and lot traceability before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 1000 V reverse voltage rating is necessary for mains-connected or high-voltage secondary side applications. The 2 A current rating suits moderate power requirements where surface mounting is preferred over through-hole alternatives. Evaluate thermal management needs based on the ambient temperature and expected duty cycle to ensure operation within safe junction temperature limits.

Bridge Rectifier Part Context

This device belongs to the DBLS series of bridge rectifiers from Taiwan Semiconductor. The series offers various voltage ratings including 50 V, 100 V, 200 V, 400 V, 600 V, and 1000 V options. The DBLS207G specifically addresses the higher voltage segment, providing a reliable solution for applications demanding increased reverse blocking capabilities while maintaining a compact footprint.

Bridge Rectifier Replacement Considerations

Compatible substitutes include the DBLS205G (600 V rating) if voltage headroom permits, or other 1000 V 2 A bridge rectifiers in similar packages such as those from Fagor Electrónica. Verify pinout compatibility and thermal resistance values when substituting to ensure equivalent performance.
