Package

The RB751V-40 is a RouterBOARD product from MikroTik, housed in a compact plastic case. It features a built-in 5-port Ethernet switch and is designed for home and small office use, providing a versatile and cost-effective networking solution.

Pinout

The RB751V-40 is a low-dropout (LDO) voltage regulator from ON Semiconductor. It typically features a pin count of 5.
The functions of the pins are as follows:
1. Input (VIN): This pin is used to connect the input voltage supply to the regulator.
2. Ground (GND): This pin serves as the ground reference for the device.
3. Output (VOUT): This pin provides the regulated output voltage.
4. Enable (EN): This pin is used to enable or disable the output. A high signal turns on the regulator, while a low signal turns it off.
5. Feedback (FB): This pin is used for feedback in applications requiring a specific output voltage, allowing for precise regulation.
The RB751V-40 is used in various applications requiring stable voltage supply with minimal power loss.

Manufacturer

The RB751V-40 is manufactured by MikroTik, a Latvian company founded in 1996. MikroTik specializes in networking equipment and software, particularly for Internet service providers and enterprise networks. The company is well-known for its RouterOS operating system, which powers their routers and provides advanced networking features. MikroTik products, including the RB751V-40, are recognized for their affordability and capabilities, making them popular among network professionals and enthusiasts.

Application

The RB751V-40 is a versatile router commonly used in network applications such as small office/home office (SOHO) setups, wireless networking, and Internet of Things (IoT) devices. It supports tasks like routing, firewall protection, and bandwidth management. Additionally, it is suitable for applications requiring VPN support and can be used in educational, retail, and hospitality environments for reliable internet connectivity and network management.

Equivalent

The RB751V-40 chip is a low-power, 40V rated, N-channel MOSFET. Equivalent products include the IRF740, STP40NF06, and BSS123, which offer similar specifications in terms of voltage and current ratings. For specific applications, it’s essential to verify parameters such as RDS(on), gate threshold voltage, and package type to ensure compatibility.
