DF10S

Bridge Rectifier Overview

The onsemi DF10S is a single-phase bridge rectifier in the DFxS family, designed for surface mount applications. It features a maximum repetitive reverse voltage (VRRM) of 1000 V and an average rectified forward current (IF(AV)) of 1.5 A at 40°C. The device supports a non-repetitive peak forward surge current (IFSM) of 50 A with an I2t rating of 10 A²s. Electrical characteristics include a maximum forward voltage (VF) of 1.1 V at 1.5 A and a maximum reverse current (IR) of 5 µA at 25°C. Thermal resistance ranges from 50 to 105 °C/W depending on the PCB land pattern. It operates within a junction temperature range of -55°C to +150°C.

Bridge Rectifier Procurement Notes

Verify component authenticity through official onsemi channels or authorized distributors. Confirm RoHS compliance and green molding compound specifications against the latest datasheet revision. Ensure ordering suffixes match required packaging formats such as tape and reel quantities. Validate thermal performance expectations based on specific PCB land pattern implementations.

Bridge Rectifier Selection Notes

Select the DF10S when high surge current ratings are necessary to maintain circuit reliability during inrush events. Consider the SDIP package dimensions for layout constraints. Evaluate thermal resistance values relative to the intended copper pad size on the printed circuit board. Compare forward voltage characteristics against alternative bridge rectifiers for efficiency optimization.

Bridge Rectifier Part Context
