B250FD

Bridge Rectifier Overview

The B250FD is a fast recovery bridge rectifier manufactured by Diotec Semiconductor, designed for high-speed switching applications. It features an average forward current rating of 1 A and a peak repetitive reverse voltage of 250 V. The device exhibits a maximum forward voltage drop of 1.3 V at 1 A and a typical reverse recovery time of 300 ns. Electrical characteristics include a leakage current below 5 µA at rated voltage and a junction capacitance of 25 pF. Thermal performance is defined by a thermal resistance from junction to ambient of 60 K/W and junction to terminal of 22 K/W. The component operates within a temperature range of -50°C to +150°C.

Bridge Rectifier Procurement Notes

Verify the exact ordering suffix against the manufacturer's official catalog to ensure correct packaging and tape specifications. Confirm RoHS compliance status and REACH registration details directly through the supplier documentation before finalizing procurement orders.

Bridge Rectifier Selection Notes

Select this component when a 1 A bridge rectifier with fast recovery characteristics is required. Ensure the circuit design accounts for the recommended protective resistance (Rt) of 15.0 Ohms to limit surge currents effectively. Verify that the operating ambient temperature remains within the specified limits for optimal thermal performance.

Bridge Rectifier Part Context

This part belongs to the B40FD to B380FD series of fast recovery bridge rectifiers from Diotec Semiconductor. The series provides various voltage ratings while maintaining consistent current handling capabilities. The B250FD specifically addresses applications requiring 250 V blocking voltage in compact bridge configurations.

Bridge Rectifier Replacement Considerations

Direct substitutes must match the 1 A current rating, 250 V reverse voltage, and fast recovery speed. Verify pinout compatibility and package dimensions before substitution.
