MBRS360T3G

The MBRS360T3G is a Schottky diode that’s perfect for power supply and rectification applications. With a low forward voltage drop of around 0.45V at 3A, it helps reduce power loss and heat generation, making it more efficient, especially in low-voltage circuits. This diode is built for high-speed switching, ideal for DC-DC converters and rectification.

It can handle 3A of continuous current, making it suitable for moderate power applications. With a reverse voltage rating of 60V, it can handle voltage spikes, making it durable in overvoltage situations. Plus, its low reverse leakage current ensures minimal energy loss.

The SMB (DO-214AA) package makes it perfect for space-constrained designs, and it operates in temperatures from -55°C to +125°C, making it suitable for automotive and industrial use. It’s also great for ESD protection, keeping your sensitive electronics safe.

MBRS360T3G Pinout Diagram

The NUP2105LT1G Schottky diode has two main pins:

• Pin 1 (Anode): This is the positive side. When the diode is forward-biased, current flows in from here. Make sure it’s connected to the positive side of your circuit, like the input power.

• Pin 2 (Cathode): This is the negative side, where the current exits. It’s typically connected to the load or the output of your rectifier circuit.

In a power supply or rectifier setup, the anode should be connected to the positive voltage, and the cathode to the negative side. If you reverse the connections, the diode won’t work and could be damaged by reverse voltage.

Since this diode is in an SMB package, ensure it’s placed correctly on the PCB to match its polarity. Schottky diodes generate little heat, but always consider thermal management for high-power applications.

MBRS360T3G Equivalent High-Current Diode

When comparing the MBRS340T3G, 1N5822, and MBRS360T3G, here’s what you need to know:

The MBRS340T3G is similar to the MBRS360T3G, but it has a lower reverse voltage rating of 40V instead of 60V. It’s perfect for moderate power applications where 40V protection is enough. It also has a low forward voltage drop (0.45V at 3A), making it efficient.

The 1N5822 comes in a different package (DO-201AD) but offers similar performance to the MBRS360T3G, with a 40V reverse voltage rating and the ability to handle 3A of current. It’s commonly used in power supplies but is a bit bulkier than the SMB package.

If your circuit needs higher reverse voltage protection, go with the MBRS360T3G. Also, keep in mind the package size when choosing replacements.

MBRS360T3G Bridge Rectifier Circuit

The Bridge Rectifier circuit shown here is used to convert AC (alternating current) into DC (direct current). This is common in power supplies when you need a stable DC voltage from an AC source.

In this setup, four diodes (D1, D2, D3, and D4) are arranged in a bridge. During the positive half-cycle of the AC input, diodes D1 and D4 conduct, allowing current to flow through the load. In the negative half-cycle, diodes D2 and D3 conduct, ensuring the current always flows in the same direction through the load.

The MBRS360T3G Schottky diodes are used in this circuit because of their low forward voltage drop (0.45V), ensuring efficient power conversion with minimal loss. They also have fast switching, which is key for high-frequency operation, and can handle up to 3A of current for moderate power needs.

The output is pulsating DC, and you can smooth it out further with a filter capacitor for a cleaner output.

MBRS360T3G Flyback Converter Example

In a flyback converter, the MBRS360T3G Schottky diode is used to rectify the voltage and provide a stable DC output. Here’s how it works:

The MOSFET controls the energy flow to the transformer. When the MOSFET turns on, energy is stored in the transformer. When it turns off, the energy is released through the secondary winding as AC voltage. The MBRS360T3G diode then rectifies this AC voltage into DC. Its low forward voltage drop (0.45V) ensures minimal power loss, making it highly efficient for high-frequency operations.

After rectification, the output is still pulsating DC, so the output capacitor smooths it out to provide stable DC voltage for the load, like a device needing DC power.

MBRS360T3G Load Dump Protection Circuit

This circuit is designed to protect your electronics from overvoltage caused by load dumps in cars or other power systems. It uses diodes to clamp excessive voltage, ensuring it doesn’t damage your components. The shunt regulator helps keep the voltage stable, so everything runs smoothly. An N-channel MOSFET controls when the protection kicks in, only activating when necessary. Resistors and capacitors play a supporting role by stabilizing the voltage and ensuring the circuit operates reliably.
