The SMP13-M3/85A is an ultra-low-capacitance transient voltage suppression (TVS) diode. It is designed to protect sensitive electronic equipment from voltage transients induced by electrostatic discharge (ESD), electrical fast transients (EFT), and lightning. The device is Diode-Transil, also known as Transil diodes or protective diodes.

The SMP13-M3/85A offers superior transient protection in a very small package, making it perfect for applications with strict space requirements. This device is popular for automotive electronic applications such as in anti-lock braking systems, parking and tire-pressure sensors, and other automotive electronic systems.

In terms of design, the SMP13-M3/85A consists of a semiconductor substrate with a conductive layer, namely a Zener diode, and high-temperature-resistant ceramic substrate. The diode is designed to limit peak pulse current and clamp the voltage to a low safe level. As current flows into the diode, the voltage across it increases until it reaches the clamping voltage. At this point, the diode starts to conduct, limiting the voltage across it to the clamping voltage and allowing the current to flow freely until the charge is dissipated.

The SMP13-M3/85A offers low capacitance, high peak pulse current capability, fast response time, and low clamping voltage. This allows it to be used in a wide variety of applications, including automotive, telecom, and computers, as well as high-speed industrial networks. Additionally, its small size makes it ideal for use in small spaces.

The SMP13-M3/85A is especially useful in automotive applications because it can effectively suppress transients and protect sensitive electronics from voltage spikes. It can protect devices from ESD and EFT pulses with peak currents up to 13A and can withstand peak pulse power of more than 1500W. It also has a very fast response time for protecting sensitive electronics from transient voltage spikes.

The SMP13-M3/85A is also perfect for telecom and computer applications due to its low capacitance and low clamp voltage. This makes it ideal for use in small spaces and is often used as a protection device for Ethernet and fiber optic cables. It is also suitable for use in high-speed or mission-critical operations, where data accuracy and protection from voltage transients is essential.

In summary, the SMP13-M3/85A is an ultra-low-capacitance transient voltage suppression diode with high peak pulse current and power capabilities. It can protect electronics from electrostatic discharge, electrical fast transients, and lightning. It is typically used in automotive, telecom, and computer applications, as well as in industrial networks for protecting high-speed data or mission-critical operations. It is also perfect for use in small spaces due to its small size.
