CBRDFA4-100 TR13 PBFREE

Bridge Rectifier Overview

The Central Semiconductor CBRDFA4-100 is a surface mount silicon full-wave bridge rectifier housed in a BR DFN-A package. It utilizes glass passivated chips within a durable epoxy case. The device supports a peak repetitive reverse voltage and DC blocking voltage of 1000 V, with an average forward current rating of 4.0 A at 112°C case temperature. Peak forward surge current reaches 150 A for 8.3 ms pulses. Electrical characteristics include a maximum forward voltage of 1.0 V at 4.0 A and a typical reverse leakage current of 5.0 µA at 1000 V. Junction capacitance is 45 pF at 4.0 V reverse bias. Operating and storage temperatures range from -55 to +175 °C.

Bridge Rectifier Procurement Notes

Verify the PBFREE suffix confirms lead-free plating compliance as specified in ordering instructions. Ensure the BR DFN-A package dimensions match the PCB footprint requirements. Confirm that the 1000 V reverse voltage rating aligns with the system's peak line voltage specifications. Check thermal management needs for the 4.0 A continuous current operation.

Bridge Rectifier Selection Notes

Select this component when a high-voltage bridge rectifier is required in a compact surface mount form factor. The 1000 V rating suits universal input AC applications. Consider the 175 °C junction temperature limit for high-temperature environments. Evaluate the 4.0 A current capacity against the load requirements to ensure adequate margin.

Bridge Rectifier Part Context

This part belongs to Central Semiconductor's series of surface mount bridge rectifiers. The BR DFN-A package provides a low-profile solution for space-constrained designs. The product line targets general-purpose power conversion applications requiring robust performance and reliable operation under varying thermal conditions.

Bridge Rectifier Replacement Considerations

Check datasheets for equivalent 4 A, 1000 V bridge rectifiers in the BR DFN-A or similar surface mount packages. Verify pinout compatibility and electrical parameters such as forward voltage and reverse leakage before substitution.
