TVS - Diodes are an invaluable component for protecting electronic systems devices from damage due to power-related disturbances. The 1SMC85A TR13 is a transient voltage suppressor diode developed by EPCOS that is designed to protect against electrical transients in applications ranging from automotive, telecommunications, industrial automation, and consumer appliances. This article will discuss the application fields and working principle of the 1SMC85A TR13.

Application Fields

The 1SMC85A TR13 is designed to be used for over-voltage protection of all kinds of automotive and industrial applications. This TVS diode is ideal for offering reliable protection of low-voltage circuits such as those found in vehicles, telephone equipment, industrial automation, consumer appliances, LED lighting, and other devices. This diode can handle voltages up to 400V and is designed to be used in high-speed circuit designs up to 58V with peak surge currents up to 45A. This diode is designed for use in high-temperature environments operating up to 150 ° C. In addition, the 1SMC85A TR13 is UL certified and can be used in applications requiring UL recognition.

Working Principle

The 1SMC85A TR13 is a bipolar junction diode with a high-speed switching capability that can suppress and limit transients above the diode’s breakdown voltage. The breakdown voltage is usually in the region of 400V, and the amplitude of the transient is limited by the reversed bias breakdown voltage of the diode. The 1SMC85A TR13 has a response time of 1ns, which makes it suitable for high-speed switching applications. When the voltage rises and exceeds the breakdown threshold, current will flow from the anode to the cathode through the diode, which will reduce the potential of the transient and provide the desired protection to the device.

The TVS diode offers a high level of protection against electrical transients while also allowing for a significant reduction in component size thanks to its high-speed switching capability. This makes it an ideal solution for applications where space is at a premium. The 1SMC85A TR13 is also designed for a long service life, with a maximum surge current rating of 45A and an average failure rate of less than 0.3 percent per billion hours of operation.

The 1SMC85A TR13 is an efficient and reliable solution for protecting electronic systems devices from electrical transients and over-voltage surges. This diode is designed to be used in a wide variety of automotive and industrial applications and offers a high level of protection against electrical transients, while also allowing for a significant reduction in component size and a long service life. The 1SMC85A TR13 is a cost-effective solution for protecting electronic devices from damage due to power-related disturbances.
