S250K

Bridge Rectifier Overview

The S250K is a single-phase surface-mount bridge rectifier manufactured by Diotec Semiconductor. It features an average forward current (IFAV) of 1 A and peak reverse voltage ratings exceeding 400 V. The device operates within a junction temperature range of -50°C to +150°C. Key electrical parameters include a maximum forward voltage of 2.1 V at 1 A, a typical reverse recovery time of 1500 ns, and a typical junction capacitance of 10 pF. Thermal resistance from junction to ambient is typically 60 K/W, while junction-to-terminal resistance is 20 K/W.

Bridge Rectifier Feature Summary

• Integrated four-diode bridge configuration for single-phase AC-DC conversion
• Designed with Protectifiers® technology for enhanced reliability in standard commercial applications
• Capable of handling high surge currents up to 75 A under non-repetitive 10/1000µs pulse conditions

Bridge Rectifier Applications

• Standard commercial and industrial power supply circuits
• General-purpose AC to DC rectification modules
• Consumer electronics requiring compact bridge rectification

Bridge Rectifier Procurement Notes

Verify the specific voltage sub-grade required, as datasheet values indicate ratings greater than 400 V. Confirm compliance with RoHS and ELV directives during sourcing. Ensure thermal management aligns with the specified 60 K/W junction-to-ambient resistance for reliable operation at rated currents.

Bridge Rectifier Selection Notes

Select this component when a 1 A average current rating and over 400 V blocking capability are necessary. Consider the 1500 ns reverse recovery time for frequency limitations. Evaluate the need for external protective resistance if charging capacitors directly from mains, based on the provided Rt and CL calculations.

Bridge Rectifier Part Context

The S250K belongs to the S125K/S250K series of SMD Single Phase Bridge Rectifiers. It shares the same physical footprint and thermal characteristics as the S125K but offers higher voltage blocking capabilities. This series utilizes Protectifiers® technology for robust performance in standard applications.

Bridge Rectifier Replacement Considerations

Check for equivalent 1A, >400V SMD bridge rectifiers from other manufacturers. Verify pinout compatibility and ensure replacement parts meet the same thermal resistance and surge current specifications.
