Bridge Rectifier Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics also lists this part number. Confirm that the component meets RoHS requirements and is lead-free. Ensure the KBPM package footprint matches the target PCB design. Check for any obsolescence notices or lifecycle changes before finalizing procurement plans.

Bridge Rectifier Selection Notes

Select this component for applications requiring a compact, through-hole single-phase rectifier with a 100 V reverse voltage rating. The 2 A current capacity suits low-power AC-DC conversion tasks. Consider the physical dimensions of the SIP-4 package when designing the enclosure. Verify thermal management needs based on the expected load current and ambient temperature conditions.

Bridge Rectifier Part Context

The 3N254 belongs to the family of standard silicon bridge rectifiers from onsemi. It serves as a fundamental passive component in power electronics, converting alternating current to direct current. The KBPM package offers a balance between cost-effectiveness and reliability for mass-produced electronic devices requiring simple rectification stages.

Bridge Rectifier Replacement Considerations

Consult official cross-reference data for compatible substitutes. Ensure replacement parts maintain identical voltage, current, and package specifications.
