TVS - Diodes: JAN1N6144US application field and working principle.

TVS-diodes, also known as Transient Voltage Suppression Diodes, are high-speed semiconductor devices used to protect circuits from transients and other transient voltages induced by lightning, electrostatic charge, or electrical faults. They are designed to limit peak current and voltage levels that can cause damage to sensitive equipment. The JAN1N6144US is an example of a TVS diode, and this article will discuss its application field and working principle.

Application Field

The JAN1N6144US is commonly used in power converters and generators, and is an ideal choice for designers looking for a reliable and economical over-voltage protection solution. It features a dual-silicone construction that makes it suitable for 5V to 36V input systems. It has a very fast response time and excellent surge capability. It also offers good ESD protection with 700W peak pulse power, and can handle pulse currents up to 5A. As a result, the JAN1N6144US is well-suited for applications requiring fast transients and high surge capability. It is also a suitable choice for usage in sub-assemblies and PC boards.

Working Principle

At its most basic level, the JAN1N6144US works by clamping the voltage between its anode and cathode terminals when an over-voltage is detected. It is designed with two parallel silicon diodes that share the same doping and cutting process. Its circuitry is embedded in a monolithic dual-silicone substrate, which provides excellent performance, low thermal resistance and high ESD protection. To ensure these features, the substrate is moulded with a specially designed coating to further minimise the thermal resistance and achieve the desired electrical characteristics.

When an over-voltage occurs, the first diode experiences a forward bias, causing a voltage drop across the diode. This in turn, triggers the second diode, resulting in a clamping of the voltage between the anode and cathode terminals. This clamping of voltage limits further increases of voltage, mitigating any damage to the protected circuit. A zener diode is also present to increase the clamping voltage of the JAN1N6144US, increasing its tolerance to transients and surges. This is because the zener diode clamps the voltage of the positive terminal, preventing any further rise of the voltage.

Conclusion

The JAN1N6144US is an example of a TVS diode used to protect circuits from transients and other transient voltages induced by lightning, electrostatic charge, or electrical faults. It is commonly used in power converters and generators and features a dual-silicone construction that makes it suitable for 5V to 36V input systems. Its working principle involves the triggering of two parallel silicon diodes and the clamping of the voltage between the anode and cathode terminals. As a result of its fast response time and excellent surge capability, the JAN1N6144US is an ideal choice for designers looking for a reliable and economical over-voltage protection solution.
