DF02M

Bridge Rectifier Overview

The onsemi DF02M is a single-phase bridge rectifier designed for printed circuit board mounting. It utilizes glass passivated junction technology to achieve low leakage current characteristics. The device features a peak average forward current rating of 1.5A and a maximum repetitive peak reverse voltage of 200V. It operates within a temperature range of -55°C to 150°C junction temperature. The component is housed in a 4-pin PDIP package with dimensions of 8.51mm length, 6.5mm width, and 3.3mm height. Key electrical parameters include a peak non-repetitive forward surge current of 50A and a peak forward voltage of 1.1V.

Bridge Rectifier Feature Summary

Bridge Rectifier Procurement Notes

Verify the manufacturer part number against official onsemi documentation to ensure authenticity. Confirm that the specified voltage and current ratings match the application requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the packaging type corresponds to the intended assembly method. Validate the date code and lot traceability through authorized distribution channels.

Bridge Rectifier Selection Notes

Select this component when a 1.5A continuous current and 200V reverse voltage capability are required in a surface-mount or through-hole DIP format. Consider the 150°C maximum junction temperature for high-thermal environments. Evaluate the 50A surge current rating against potential inrush currents in the target circuit. Compare physical dimensions against available PCB footprint constraints.

Bridge Rectifier Part Context
