The RCLAMP1851ZATFT is a new and advanced surge protector, part of the TVS - Diodes category. It is designed for use on sensitive electronics, including servers, computers, data networking, and industrial systems, in order to guard against undesirable overvoltage levels. It is also suitable for use in automotive, home appliance, LED lighting, wireless, medical device, and consumer electronics applications.

The RCLAMP1851ZATFT uses a new and innovative technology to prevent and minimize the likelihood of permanent damage caused by overvoltage transients. It does this by diverting the transient voltage away from the sensitive electronics, and releasing it to the ground. The protector uses a high safety margin which ensures its compliance.

Working Principle

The RCLAMP1851ZATFT works by using a combination of two highly reliable technologies to protect sensitive electronics. When an overvoltage transient arises, an off-chip varistor absorbs the energy by clamping the voltage and energy to a safe level. This works in conjunction with an integrated zener diode, which operates in parallel to bring down the voltage level further.

The protector additionally features an integrated diode network which ensures that the applied overvoltage clamping does not interfere with the normal operation of the system.

The protector operates within a current redundancy of 5kV/μs, ensuring a very fast response-time, and ensuring total protection from destructive overvoltage transients. The protector is also highly resilient to reverse-polarity surges, abrupt discharge, and other transient threats.

A further aspect of the RCLAMP1851ZATFT’s working principle is its ability to withstand and absorb high levels of electrostatic discharge, as indicated by its IEC 61000-4-2 contact ESD rating of 15kV. Overall, the RCLAMP1851ZATFT offers superior protection against the broad range of transient voltage levels.

Conclusion

The RCLAMP1851ZATFT is an advanced surge protector, designed to offer protection for sensitive electrical components. It works in a combined model, which couples the protection of a varistor and a zener diode. Additionally, the protector is highly resilient against transient threats, and has a very fast response-time. It is suitable for a broad range of applications, especially in the automotive, industrial, home appliance, LED lighting, wireless, medical device, and consumer electronics industries.
