MBR4035PTHC0G Application Field and Working Principle

Introduction to Diodes - Rectifiers - Arrays

Diodes - Rectifiers - Arrays are electronic devices which perform the basic function of converting alternating current (AC) to direct current (DC). They are commonly used in power supplies that rapidly convert AC to DC, such as in computers and other electronic equipment. Rectifier diodes make up a major class of devices that are used for rectifying current, meaning that they can allow the current to go in one direction only.

Arrays consist of several individual diodes that act together in a single package, and often act as a circuit component in its own right. As such, they are used to provide more efficient rectification than individual diodes. This is because they are able to convert a higher input frequency into an output with less energy loss.

MBR4035PTHC0G

The MBR4035PTHC0G, from ON Semiconductor, is a 35 A, 400 V, surface mount Schottky rectifier in a 4-pin TO-220 package. This device has extremely low forward voltage drop, fast switching speed, and displays low reverse leakage current.

Applications of MBR4035PTHC0G

The MBR4035PTHC0G is typically used in high frequency power supplies, converters, mobile and telecom equipment, motors, and general purpose power rectification. It is also suitable for automotive and industrial applications.

MBR4035PTHC0G Working Principle

The MBR4035PTHC0G uses Schottky (or hot carrier) technology, which is a type of rectification. This type of rectification consists of a p-n junction which is biased by a small voltage and with a low current. A Schottky diode will pass current in either forward or reverse directions and the reverse current is much lower than with conventional diodes.

When the MBR4035PTHC0G is in forward bias, it behaves much like a regular diode by allowing current to pass in one direction only. When in reverse bias, it blocks current flow in the opposite direction, as with a regular diode. When the forward voltage bias is exceeded, the breakdown voltage of the diode, it will conduct current in either direction.

Advantages of the MBR4035PTHC0G

The MBR4035PTHC0G offers several advantages over conventional diode rectifiers, including:

1. Extremely low forward voltage drop, as low as 0.65 V at room temperature.
2. High switching speed, typically 600 ns.
3. Negligible reverse leakage current.
4. High junction temperature rating of 150C.
5. Low forward voltage temperature coefficient for high stability.

Conclusion

The MBR4035PTHC0G is a high-speed, low-temperature Schottky rectifier that offers numerous advantages over traditional rectifiers. It is suitable for a wide range of applications, such as telecom and automotive, and can be used to convert AC to DC rapidly and efficiently.
