The DT2041-04SO-7 device is a multi-avalanche breakdown voltage varistor from the VAR series of TVSs, developed by Beijing Dynamic AC Tech Co., Ltd.

DT2041-04SO-7 is a bi-directional, 4-terminal DIP TVS diode. It features a dynamic response time of less than 1ns and a standoff voltage of 7V. The device is housed in a plastic case that measures 5.07mm x 4.14mm x 2.03mm and is RoHS compliant. Its maximum reverse surge current rating is 300A and its maximum continuous forward current is approximately 200mA.

Application field

The DT2041-04SO-7 is primarily used for ESD protection and in overvoltage circuits. It can be used in a variety of applications, including: Computers and peripheral equipment, consumer electronic devices, industrial electronics, automotive electronics, and communication systems. It is also suitable for applications where a high degree of circuit protection is required.

Working Principle

The working principle of the DT2041-04SO-7 is based on the avalanche breakdown phenomenon. The chip contains a junction in which, under the influence of an external voltage, the numbers of majority carriers increase dramatically. This results in a further increase in current which causes the temperature of the junction to reach a critical level. At this point, the avalanche breakdown effect occurs and results in a high diode conductivity, protecting the device from overvoltage and ESD.

The DT2041-04SO-7 is an efficient device able to absorb a large amount of energy and that also features surge current protection for a wide range of voltages. It is ideal for use in applications where high levels of circuit protection are needed.

In short, the DT2041-04SO-7 is a bi-directional, 4-terminal DIP TVS diode that is used in a variety of applications for overvoltage and ESD protection. Its dynamic response time and maximum reverse surge current rating make it ideal for applications where high levels of circuit protection are required.
