DF005S datasheet



DF005S bridge rectifier diode has a peak reverse voltage of 50V and a maximum average forward rectified current of 1A.

The bridge rectifier is commonly used in power supply circuits to provide a stable DC voltage for electronic devices.


1. UL recognition, file number E54214
2. Ideal for automated placement
3. High surge current capability
4. Meets MSL level 1, per J-STD-020, LF maximum peak of 260 °C


1. The bridge rectifier configuration of provides a stable and reliable DC voltage output, which is essential for electronic devices that require a consistent power supply.

2. The surface mount design of bridge rectifier diode makes it easy to install and saves space on printed circuit boards.

3. The fast recovery time and low forward voltage drop of bridge rectifier diode improve the overall efficiency of the power supply circuit.


1. The maximum average forward rectified current of 1A may not be sufficient for high-power applications.

2. The bridge rectifier configuration of introduces a voltage drop that can reduce the overall efficiency of the power supply circuit.

3. The bridge rectifier diode is polarized and must be connected in the correct orientation to function properly.
