TVS-Diodes (Transient Voltage Suppression Diodes) are a type of semiconductor device used to protect electrical circuits from surge or transient voltage spikes. They’re also referred to as “Transient Voltage Clamping Devices”. The 5KASMC30AHM3/57 is a monolithic, planar, surface-mounted Transient Voltage Suppression (TVS) device specifically designed to protect against high surge voltages, typically caused by electrostatic discharge (ESD) or other applications where low capacitance is desired.ApplicationsThe 5KASMC30AHM3/57 can be used for many different applications where high surge protection is needed. Some examples include automotive, consumer, industrial, medical, military and aviation electronics. Common applications include automotive automotive DC/DC converters, communication systems and other high-speed logic interfaces, and power supply & distribution boards.How it WorksTVS-Diodes operate by redirecting or “clamping” any incoming voltage surge away from sensitive components. When the voltage exceeds a predefined threshold, the device will begin conducting electricity, redirecting the current away from the protected component. As voltage levels return to normal, the device will automatically return to an off state, protecting against any further spikes. The 5KASMC30AHM3/57 is designed to operate in high-voltage environments up to 400V, withstanding repetitive surge voltages up to 28A.PackageThe 5KASMC30AHM3/57 is offered in a SOT-23 package, a compact three-Leaded-Package (3LPP) that is designed to reduce both physical and electrical stress due to the limited volume and reduced leads. This device has a thermal resistance of 45°C/W, allowing for improved heat dissipation.SpecificationsThe 5KASMC30AHM3/57 is rated to operate within a temperature range of -55°C to 150°C. It can tolerate a high pulse load of up to 60A for 10µs after a surge voltage of 400V. It has a maximum clamping voltage of 16V @ 8A, a response time of 8ns, and a capacitance of 2.5pF. This device also has an operational stability specification of 0.2%/1000hrs @ 250°C. It has a minimum on-state current of 5mA and a maximum operating voltage of 400V.ConclusionThe 5KASMC30AHM3/57 is an ideal solution for protecting against high surge voltages and transient voltage spikes. It offers excellent performance and reliability in a wide range of applications. Its small form factor makes it an ideal choice for space-constrained designs, while its low capacitance and fast response time make it an excellent option for high-speed logic interfaces. With a rugged SOT-23 package and high surge and temperature ratings, the 5KASMC30AHM3/57 is an ideal choice for protecting sensitive electronic components from over-voltage spikes.
