The highly efficient 1N5393S-T rectifier is used in various fields and applications, thanks to its wide range of operating parameters, low forward voltage drop and fast response time. The device is also capable of operating with both low and high reverse current voltages. The 1N5393S-T diode is mainly used in power supplies, converters, dual and isolation circuits, overvoltage protection circuits, and snubber circuits.

Overview of the 1N5393S-T

The 1N5393S-T belongs to the STMicroelectronics’ 1N5393S rectifier family. It is a single-phase, 3A (average), 40V rectifier, housed in the DO-201AD plastic package. Its forward voltage drop at 20A is less than or equal to 0.85V. The diode has a high surge current rating of lesser than or equal to 320A and its operating junction temperature is - 55 to + 150 degrees Celsius.

Working Principle of the 1N5393S-T

The 1N5393S-T operates in two distinct power modes; forward conduction mode and reverse blocking mode. In forward conduction mode, the electrodes of the diode are forward biased and current flows through it. The current-voltage characteristics of a silicon diode indicate that the voltage of the device decreases as the current through it increases. This phenomenon is called “Forward Voltage Drop”.

In the reverse blocking mode, the electrodes of the 1N5393S-T are reverse biased and no current flows through the device. The device provides a high blocking voltage that prevents current from flowing. The reverse recovery time and reverse avalanche energy of the diode are also quite low, resulting in less power dissipation.

Applications of the 1N5393S-T

The 1N5393S-T is used in a variety of applications. The device is used in power supplies, converters, and dual and isolation circuits for EMI or surge protection. It is also used in overvoltage & over-current protection circuits, snubber circuits and automotive lighting circuits, for example, for vehicle turn signals or rear fog lights.

Its wide operating parameters, low voltage drop and fast response time also make it suitable for use in switching power supplies, DC-DC converters, bridge circuits and power management systems. In addition, the device is suitable for use in high ripple current applications such as motors and inverters.

Features of the 1N5393S-T
