RB400DT146 Discrete Semiconductor Products

The RB400DT146 is a single piece molded package rectifier which is mainly used for installation in a bridge rectifier assembly. It is manufactured by Semikron and is used in low and high frequency applications, as well as in low power switch mode applications.

The RB400DT146 rectifier uses a single terminal pair, which allows it to be mounted in a footprint as small as 1cm x 0.9cm. Its high thermal conductivity and low junction-to-case thermal resistance, provide cooling to its lowprofile package. It is designed for use in high voltages up to 400V and can handle up to 140A peak repetitive reverse current.

The RB400DT146 rectifier uses a high density, non-isothermal (NED) process technology. This process technology provides optimal properties for a low-profile bridge rectifier technology, allowing for improved high frequency snubbing, low forward voltages and good thermal stability.

The working principle of a rectifier is to convert alternating current ( AC ) into direct current ( DC ). The RB400DT146 rectifier is a full wave bridge rectifier which uses a diode bridge arrangement to convert AC input voltage into a DC output voltage. The bridge arrangement consists of four diodes in a closed loop configuration.

When the AC voltage is applied to the input of the rectifier, it passes through two of the diodes, while the other two diodes are reverse biased. The current flows in two directions through the two diodes and then combines in the output terminals to form a single DC output voltage. Since the diodes are in reverse biased, the current flow is limited to one direction, and the output voltage is converted to a DC signal.

The RB400DT146 rectifier is designed for a variety of applications that require conversion of AC input voltage to DC output voltage. Examples include dc to dc converters, inverters, power supplies, chargers, and energy storage systems. It is also suitable for industrial and consumer applications, including motors, appliances, lighting and electronic equipment.

The RB400DT146 rectifier is a low-profile, cost-effective solution for applications that require high frequency snubbing and low forward voltage drops. Its high-density NED process technology provides improved high frequency snubbing and low forward voltages, while its low junction-to-case thermal resistance ensures reliable cooling of the low-profile package. Its ability to withstand high voltages up to 400V, and pulsed current ratings up to 140A, makes the rectifier suitable for a variety of applications.

In summary, the RB400DT146 rectifier is a one piece, low profile, cost-effective solution for applications that require conversion of AC input voltage to DC output voltage. It uses a high-density, nonisothermal (NED) process technology which provides improved high frequency snubbing and low forward voltage drops, while its thermal conductivity ensures reliable cooling of the low profile package. Its ability to handle voltages up to 400V and pulsed current ratings up to 140A make it suitable for many applications.
