SMP15A-E3/85A

A TVS diode, also known as a Transient Voltage Suppression Diode, is a form of semiconductor designed specifically to respond to sudden changes in voltage. The primary application is to protect vulnerable electronics from damage caused by transient voltage spikes. The SMP15A-E3/85A TVS diode is a unidirectional device, with a voltage rating of 15 volts and a peak pulse current rating of 85 amps.

The primary purpose of the SMP15A-E3/85A is to protect against transient voltage events, such as electrostatic discharges (ESD) and other voltage spikes that may be caused by lightning, inductive switching, or other sources. It does this through clamping, which limits the peak voltage by diverting excessive current away from the protected circuits, and by absorbing the electrical energy of the transient voltage. The SMP15A-E3/85A has an impressive peak pulse power rating of 1375 watts, offering unmatched protection for vulnerable components such as voltage converters, power supplies, and control circuits.

The structure of the SMP15A-E3/85A is cleverly designed to offer a range of protection features. It consists of a very low-threshold PN junction, with a built-in avalanche voltage that can quickly react to any sharp voltage changes. Additionally, it features a surge rating of eight nanoseconds, meaning that it can manage sustained transients in the microsecond range. The SMP15A-E3/85A also features thermal shutdown capability, which prevents damage from excessive heat by raising the device’s trip temperature.

In terms of application, the SMP15A-E3/85A TVS diode is designed to be used in a variety of different scenarios. It is especially well-suited for power supplies, offering superior protection for sensitive components such as data converters, as well as other electronics that might be vulnerable to damage from transient voltage spikes. It is well-suited for applications such as consumer electronics, medical devices, automobiles, and other high-voltage situations.

In summary, the SMP15A-E3/85A TVS diode is an excellent choice for protecting vulnerable electronics against transient voltage events. It features an impressive peak pulse rating, a low surge rating, and thermal shutdown capability. Additionally, it is versatile enough to be used in a variety of different applications, making it a great choice for those looking to provide superior protection for their electronics.
