The R7S00212XX rectifiers also serve as replacements for standard rectifiers in semiconductor and electronic equipment.

Features

The R7S00212XX rectifiers offer a wide range of features, making them even more attractive for use in low-voltage applications.

• Small package size
• Low forward voltage (2.2 V)
• Low current consumption
• High average forward current (5A)
• High temperature operation (125°C)
• High surge forward current (50A)

Working Principle

Diodes are two-terminal, semiconductor electronic components that allow current to flow only in one direction, while blocking current flow in the opposite direction. The R7S00212XX rectifiers, like other diode rectifiers, are designed to exploit this feature of diodes by converting AC current into DC current.

For the R7S00212XX rectifiers, the input voltage must be high enough to turn the diode "on". Once "on", the diode will pass the current and the output is a DC voltage. In low-voltage applications, the forward voltage drop (Vf) of the diode is critical, as it directly affects the output voltage of the rectifier. Fortunately, the R7S00212XX rectifiers have an exceptionally low forward voltage of 2.2 V, which allows for safe and efficient operation.

Conclusion

The R7S00212XX series diodes from ROHM are compact and reliable diode rectifiers with a wide range of features that make them an ideal choice for low-voltage applications, such as switching power supplies, brushless DC motor control and lighting.
