Transient voltage suppressors (TVS) are used to protect circuits from short-term overvoltage, typically lightning or high energy transients. They are a type of diode-based voltage protection device intended to protect equipment from voltage spikes. These spikes can permanently damage the electrical circuit, and also lead to malfunction and improper functioning of other parts of the system.

The CM1641-04D4 is an example of transient voltage suppressor diode, with its main application field and working principle discussed in this article. The CM1641-04D4 is a transient voltage suppressor diode designed to protect sensitive electronics from overvoltage and transients. Its reverse standoff voltage is 4V and its peak pulse power is 400W, with a peak pulse current of 400A.

The CM1641-04D4 is commonly used in a variety of applications ranging from automotive, consumer electronics, industrial, computer, to telecom. It can be used in small power supplies, electrical control systems, as a large surge protectors, and in mobile phone battery chargers. The diode is available in a small, through-hole package, making it an ideal choice for compact circuit boards and designs with little space.

The transient voltage peak spike is clamped to the reverse stand-off voltage of the diode, protecting the circuit. When the transient voltage is triggered, the diode\'s depletion region expands and a large current carries the energy away from the circuit. The height of the stand-off voltage of the diode determines the level of voltage spike that is blocked by the diode.

This diode\'s peak power and reverse stand-off voltage provide reliable protection from overvoltage, transients, and ESD voltage surges. In addition, the diode\'s package includes a drain lead so that sharp negative pulses may be clamped without adding additional components like capacitors. The diode also features a low junction capacitance, which prevents false triggering during data line applications.

CM1641-04D4 provides an effective and reliable circuit protection against voltage spikes and transients. Its low junction capacitance, wide reverse stand off voltage, and high power capabilities make it suitable for various applications. The diode also supports fast response time and low leakage current, making it an excellent choice for any circuit protection design that requires fast-response time and high-performance.
