TVS - Diodes are solid state components that protect electronic circuits from transient overvoltages. Transient overvoltages consist of voltage spikes that occur in electrical and electronic systems. It is usually caused by lightning strikes, power inductive loads, static discharges or other fault conditions. TVS diodes are designed to absorb and divert the energy of the transient voltage into the ground, while preventing the high voltage from damaging the sensitive components within the circuit. The 5KASMC28AHM3/9A is a TVS Diode specifically designed to protect low-cost and critical coils, drivers, and other components in electronic circuits.

The 5KASMC28AHM3/9A is a low capacitance transient voltage suppressor diode designed for automotive and industrial applications. It is a single diode with a breakdown voltage of 28V. The working principle of the 5KASMC28AHM3/9A is when voltage exceeds the breakdown voltage, the diode starts conducting, limiting the voltage to an acceptable level. The temperature range of the diode is -55℃ to 125℃. The clamping voltage of the diode is 9V above its rated breakdown voltage. The diode is contained in a small 1.2mmx1.3mm surface-mount package and is RoHS compliant.

The 5KASMC28AHM3/9A is suitable for high-speed overvoltage protection and is mainly used in automotive and low-cost industrial applications. It is used to protect fuse triggers, opto couplers, voltage regulators, and dc-dc converters from overvoltages caused by reverse or transient conditions. In automotive applications, the diode is used to protect high-side Input/Output (I/O) as well as chipsets and modules from overvoltages due to static electricity and other fault conditions. It is also used in industrial applications such as data communications and process-control networks.

The 5KASMC28AHM3/9A diode is a popular choice for automotive and industrial applications due to its low capacitance and high-speed protection. Its small size, low on-state voltage drop, and wide operating temperature range make it suitable for a variety of applications. The diode provides superior-level protection against overvoltage transients, while also keeping the voltage level within the acceptable limits for the protected components. Although its size is small, the diode provides reliable and effective surge protection for automotive and industrial applications.
