TVS - Diodes

The JAN1N6115 is one of the most powerful and versatile TVS (Transient Voltage Suppressor) diodes, with a long track record of providing reliable surge protection for power system components. In this article, we discuss the application field and working principle of the JAN1N6115 TVS diode in order to help users understand the performance of this device.

Application Field

The JAN1N6115 is designed to provide protection against overvoltage transients for power systems against lightning and other transients. It is well-suited for applications including power supply input protection (DC-DC converters, etc.), AC/DC mains input protection, and power supply line ESD protection (IEC 61000-4-2 Level 4) and other inductive load applications. It is also ideal for use in TVs, LCDs, monitors, set-top boxes, and more.

Working Principle

The JAN1N6115 is constructed from silicon-based PN-junction semiconductor material. It uses a breakdown voltage of between 3 and 15V and a peak pulse power dissipation of up to 600W. When exposed to overvoltage transients, it acts to reduce the transient’s potential to a safer level for the protected circuit. This process is achieved through suppression of overvoltage in the form of a dynamic clamp, limiting the voltage level to that of its clamp voltage. It is also capable of obtaining low clamping voltage factors, as seen in its low leakage current of ≤ 5μA.

The JAN1N6115 also has high maximum surge current capabilities, with up to 1500A peak pulse current when the peak pulse voltage exceeds the breakdown voltage. The cutoff frequency of the clamping circuit is higher than all symmetrical surge pulses in common mode surge tests. The device also obtains a high peak pulse power Zenor diode. It offers large energy absorption capability of up to 600W at a voltage of 8V.

In conclusion, the JAN1N6115 is a powerful and reliable surge protection device for power system components. It has a wide range of applications, including power supply input protection, AC/DC mains input protection, and power supply line ESD protection, among others. Its constructions utilizes a breakdown voltage of between 3 and 15V and a peak pulse power dissipation of up to 600W, allowing it to reduce overvoltage transients to a safe level for the protected circuit. The high maximum surge current and low clamping voltage factors of the JAN1N6115 make it an excellent choice for a wide variety of TVS diode applications.
