DF10SP-HF

Bridge Rectifier Overview

The DF10SP-HF is a single-phase, glass-passivated surface mount bridge rectifier manufactured by Comchip Technology. It belongs to the DFS series and features a maximum average forward rectified current of 1.0 A at an ambient temperature of 40°C. The device supports a maximum recurrent peak reverse voltage (VRRM) of 1000 V, with corresponding maximum RMS and DC blocking voltages of 700 V and 1000 V, respectively. It exhibits a maximum forward voltage drop of 1.1 V at 1.0 A DC and a typical thermal resistance of 40 °C/W. The component operates within a junction temperature range of -55°C to +150°C and is housed in a DFS package.

Bridge Rectifier Feature Summary

• Glass passivation provides mechanical strength and meets moisture resistance standards.
• Low forward voltage drop contributes to high efficiency during rectification.
• Designed for direct mounting on printed circuit boards.
• Plastic case is UL recognized with a flammability classification of 94V-0.

Bridge Rectifier Applications

• General purpose rectification in printed circuit board assemblies.
• AC to DC conversion in power supply circuits.
• Half-wave or full-wave rectification for resistive or inductive loads.

Bridge Rectifier Procurement Notes

Verify the specific ordering suffix 'P' corresponds to tube packaging when sourcing this part number. Confirm that the requested quantity aligns with standard tube counts of 50 pieces per tube or box quantities of 5,000 pieces. Ensure the procurement documentation references the correct RoHS compliance status as indicated in the manufacturer's datasheet.

Bridge Rectifier Selection Notes

Select the DF10SP-HF for applications requiring a 1000 V reverse voltage rating and 1.0 A continuous forward current capability. Consider the DFS surface mount package dimensions for PCB layout constraints. Derate the forward current by 20% if the application involves capacitive loads to ensure reliable operation within the specified thermal limits.

Bridge Rectifier Part Context

This component is part of the DFS series of SMD glass-passivated bridge rectifiers produced by Comchip Technology. The series spans various voltage ratings from 50 V to 1000 V, all sharing a common 1.0 A current rating and physical footprint. The 'DF10SP-HF' designation specifically identifies the 1000 V variant packaged in tubes, distinguishing it from the reel-packaged 'DF10S' version.

Bridge Rectifier Replacement Considerations

Compatible substitutes include other 1A, 1000V SMD bridge rectifiers in the DFS package, such as the DF10S-G from Sensitron or Sangdest Microelectronics. Verify pinout compatibility and thermal resistance specifications before substitution.
