M1.5KE16A is a transient voltage suppression (TVS) diode designed to protect sensitive electronics against overvoltages. It is part of a wide range of TVS diode solutions created by Littelfuse, a well-established and trusted leader in this technology. These low-profile (2.1 mm max. footprint) unidirectional ESD protection devices come in a 16-pin package and are compliant with IEC 61000–4–2 (ESD) and IEC 61000-4-4 (EFT) standards. When exposed to high voltages, the M1.5KE16A can reduce the voltage to protect sensitive electronic components.

The M1.5KE16A can be used in a variety of applications ranging from consumer electronics such as laptops and mobile phones to industrial items like circuit boards and automation controllers. Its low-voltage breakdown voltage of 16V and peak pulse power of 1500W make it ideal for applications operating at low-failure voltages. The M1.5KE16A also features a very low junction capacitance, providing fast response time to reduce system power. This device is RoHS compliant and has a high surge current rating, meaning it will reliably perform even in the most demanding conditions.

The working principle of the M1.5KE16A is based around its junction construction, which consists of a heavily doped p-type region and a heavily doped n-type region. When a high surge voltage is applied to the device, it causes a large amount of current to flow through the p-n junction. This current causes an avalanche breakdown, quickly neutralizing the voltage. This effect then transfers the spike voltage and energy to the device, which absorbs it without damaging the protected components.

The M1.5KE16A provides a low-profile, reliable, and cost-effective solution for overvoltage protection of components exposed to high voltage surges and ESD. Its low-voltage breakdown voltage and low junction capacitance combine to make it suitable for a wide range of consumer and industrial applications. This device provides robust protection against overvoltage surges to ensure the safe operation of sensitive electronic components.
