RB420DT146 Discrete Semiconductor Products

The RB420DT146 is a single diode-rectifier with a higher current density and maximum power dissipation than comparable devices. It is intended for use in applications that require very fast speed and low-loss switching, and its fast, low-loss switching load carrying capability is ideal for circuit protection.

The RB420DT146 is a three-terminal integrated package that has a single anode and a cathode connected to the anode and to the package input pin. The package is designed to be connected directly to the anode and cathode. The device also has a gate terminal, which is connected to the package input pin, but the gate terminal is not connected to the anode and cathode and the gate voltage must therefore be manually connected.

The RB420DT146 utilizes a unique double-armed bridge construction with a low level of parasitic inductance and capacitance. The device also has a very thin metallization layer which minimizes the resistance from terminal to body. As a result, the RB420DT146 has improved power providing an unmatched level of speed and current density.

The key output characteristics of the RB420DT146 are: forward voltage drop, current carrying capability and the switch-on time. Its forward voltage drop is typically 0.07V, which is less than the 0.3V typical for other rectifier diodes, making the device much more suitable for applications that require fast-switching, circuit protection and higher output current. The device can carry a maximum current of 1.2A at a low forward voltage drop, making it a very efficient device for power circuits.

The switch-on time of the RB420DT146 is also very fast, typically only 0.2-0.3 nanoseconds, which makes it an ideal choice for applications that require a fast response time, such as in power converters, protection circuits and switching power supplies. The switch-on time can also be adjusted depending on the application requirements.

The RB420DT146\'s advantage lies in its versatility, as it can be used for both general purpose diode application, power circuits and for fast-switching applications. Its low forward voltage drop and high current carrying capability makes it suitable for a wide range of application fields including power converters, motor control, overcurrent and overvoltage protection, switching power supplies, electro-mechanical applications, audio, video and RF circuits, and a variety of other industrial applications.

The working principle of the RB420DT146 is quite simple. The current first passes through the anode and then through the reverse connect cathode, in order for the voltage to drop due to the forward voltage drop across the diode. The current then passes through the gate and is further dependent on the current threshold. By increasing or decreasing the current, the output can be altered, as the control gate is also connected to the anode and the cathode.

In summary, the RB420DT146 is a single diode-rectifier with a higher current density and maximum power dissipation than comparable devices. It is a versatile device that can be used in various applications such as power converters, motor control, overcurrent and overvoltage protection, switching power supplies, and a variety of other industrial applications. It has a fast switch-on time and low forward voltage drop, making it suitable for a wide range of applications. The working principle of the device is quite simple, as the current first passes through the anode and then through the reverse connected cathode, and the output can be altered by the current threshold.
