Introduction to TVS - Diodes

Transient Voltage Suppression (TVS) diodes are protective devices designed to protect sensitive electronic devices against high voltage transients (“spikes”) caused by electrostatic discharge (ESD), lightning, and other power surges. They are uni-directional devices that can be used to provide overvoltage protection to semiconductor components, circuits, and systems.TVS diodes are becoming increasingly necessary for consumer and industrial applications in this day and age. They are currently used in various automotive, medical, consumer and industrial devices to protect against unwanted power surges and keep them functioning optimally.

5KASMC17AHM3/9A - Application Field and Working Principle

The 5KASMC17AHM3/9A is a Transient Voltage Suppression (TVS) diode specifically designed for automotive, medical, consumer, and industrial applications. The 5KASMC17AHM3/9A has a low profile design that makes it well suited for tight, high humidity applications where thermal dissipation may be an issue. The 5KASMC17AHM3/9A is designed to provide overvoltage protection to semiconductor components, circuits, and systems.The 5KASMC17AHM3/9A features a 17V standoff voltage and an 8A repetitive peak pulse current capability. The device has a 5 ns response time, and a guaranteed ±5% limit variation on the hold-off voltage and the trigger energy rating. The 5KASMC17AHM3/9A also features an ultra-low capacitance of 0.12pF.The 5KASMC17AHM3/9A is designed with a SOD-323 package, which provides a cost-effective, miniaturized solution for space-constrained applications. The device has a low profile design and is specifically tailored to offer overvoltage protection in environments where thermal dissipation may be an issue.When a surge is present, the 5KASMC17AHM3/9A will respond quickly and protect the connected equipment. The device works by clamping surge voltages to a safe operating voltage level. When the surge is no longer present, the 5KASMC17AHM3/9A device will reset itself and return to its resting state until another surge is detected.

Conclusion

The 5KASMC17AHM3/9A Transient Voltage Suppression (TVS) diode is an ideal choice for automotive, medical, consumer, and industrial applications. Thanks to its ultra-low profile design and low capacitance, it is well suited for tight spaces and environments with high humidity. Its 17V hold-off voltage, 8A pulse current capability, and fast 5 ns response time allow it to provide effective overvoltage protection, keeping sensitive components and systems safe from power surges.
