TISP4180H4BJR-S Application Field and Working Principle

Introduction

The TISP4180H4BJR-S is a Thyristor Surge Protector (TVS) device developed by Littelfuse. This breakthrough technology offers superior performance for Lightning and ESD Protection over traditional PPTC devices. It can suppress high-voltage incoming surges of 8.6kV or higher with a joule rating of 4.5A and a maximum device breakdown voltage of 180V. This device is extremely compact, measuring only 1.2mm x 0.9mm x 0.55mm, and provides reliable protection against high voltage surges up to 10 times greater than standard protection networks.

Application Field

The TISP4180H4BJR-S is a perfect solution for many applications including telecom / broadcast equipment, PC video / gaming consoles, data centers, photovoltaic (PV) systems, industrial automation, and other high-voltage applications. Thanks to its advanced protection circuitry, the device is designed to provide instantaneous response to both surge and ESD threats.The TISP4180H4BJR-S is suitable for use in a variety of high-voltage applications, including high-power consumer electronics, automotive electronics, telecom / broadcast equipment, PC video / gaming consoles, data centers, and photovoltaic (PV) systems. The device is also suitable for use in any other application where transient surges may cause performance degradation or damage.

Working Principle

The working principle of the device is based on the principle of thyristors. Generally, thyristors are semiconductor switching devices that are triggered by a gate current. They work by blocking current once the gate current has reached a certain threshold level. The TISP4180H4BJR-S device works by using the voltage-controlled conduction of a thyristor to provide a passive, high-speed response to surge and ESD events.When a surge or ESD event occurs, the gate current of the device is quickly exceeded, resulting in a high-voltage gate pulse that triggers the device to switch. Once triggered, the thyristor remains in its conduction mode until the current is removed, whereupon the thyristor switch is opened.This rapid switching action of the device prevents damage from high-voltage surges and ESD events. Thus, the device is designed to protect electronic devices from ESD induced breakdowns and high voltage transients.

Conclusion

The TISP4180H4BJR-S is an advanced technology providing superior surge and ESD protection for a variety of applications. The device works on the principle of thyristors, and its fast switch-on time ensures effective protection against transient surges quickly and effectively.Combined with its miniature dimensions, the TISP4180H4BJR-S is an ideal solution for all high-voltage applications.
