B250S15A

Bridge Rectifier Overview

The B250S15A is an SMD single-phase diode bridge rectifier manufactured by Diotec Semiconductor. It features a forward current (IFAV) of 1.5 A and a peak reverse voltage (VRRM) of 250 V. The device has a maximum forward voltage (VF) of less than 1.0 V at 1.5 A, with a typical leakage current under 5 µA. Peak forward surge current reaches 45 A at 50 Hz or 50 A at 60 Hz. Operating junction and storage temperatures range from -50°C to +150°C. Typical thermal resistance junction-to-ambient is 40 K/W, while junction-to-terminal is 15 K/W.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix against official Diotec documentation to confirm package type and compliance status. Confirm RoHS and halogen-free status directly from the manufacturer's datasheet before procurement. Ensure component authenticity through authorized distribution channels.

Bridge Rectifier Selection Notes

Select this component when a 1.5 A average forward current and 250 V reverse voltage rating are required in a surface-mount form factor. Consider the thermal resistance values for PCB layout planning. Verify that the surge current requirements align with the circuit's fault conditions.

Bridge Rectifier Part Context

This part belongs to the BxxxS15A series of SMD single-phase diode bridge rectifiers from Diotec Semiconductor. The series covers various voltage ratings from 40 V to 500 V, all sharing the same 1.5 A current rating and physical footprint. This specific model provides the 250 V variant within that standardized product line.

Bridge Rectifier Replacement Considerations

Check for direct equivalents in the BxxxS15A series if different voltage ratings are needed. Verify pinout compatibility and thermal characteristics when substituting with other manufacturers' SMD bridge rectifiers.
