3N258

Bridge Rectifier Overview

The onsemi 3N258 is a single-phase standard bridge rectifier designed for through-hole mounting in the KBPM package. It features a maximum average forward rectified current of 2A and a repetitive peak reverse voltage of 800V. The device exhibits a maximum DC forward voltage drop of 1.1V at rated current and has a non-repetitive peak forward surge current rating of 30A. Operating within a temperature range of -40°C to +150°C, it utilizes glass passivation for electrode protection and meets UL recognition standards.

Bridge Rectifier Procurement Notes

Verify component authenticity against official onsemi documentation due to potential availability variations. Confirm package integrity and lead marking consistency with the KBPM specification. Ensure compliance with RoHS directives if required by the target application environment. Cross-reference datasheet revisions to confirm parameter stability before final integration into production designs.

Bridge Rectifier Selection Notes

Select this component when an 800V blocking voltage and 2A continuous current capacity are required for AC-to-DC conversion. The KBPM form factor suits PCB layouts requiring through-hole assembly. Evaluate thermal dissipation requirements against the 4.7W power dissipation limit under expected ambient conditions. Consider the 1.1V forward voltage drop impact on overall system efficiency during low-voltage operation scenarios.
