TVS (Transient Voltage Suppressor) diodes are an important type of component used to protect sensitive circuitry and systems against high voltage transients. The SMP30A-M3/85A is one such diode, designed to absorb voltage transients of up to 30ALC peak per line with a breakdown voltage of 85V. It is designed for use with a wide range of applications from telecommunications and data communications systems to consumer electronic products.

The SMP30A-M3/85A is built with a high-performance monolithic structure and features a low-profile surface mount design for easy mounting. It has a patented “Dynamic Warmth Control System” that is designed to constantly adjust its breakdown voltage to minimize energy losses, resulting in superior performance and reliability. The diode is also designed to provide protection against overvoltage, overcurrent, and reverse current. The SMP30A-M3/85A is available in a variety of packages, including SMA, SMC, SOT-223, and SC-75.

The working principle of the SMP30A-M3/85A is based on the Zener diode, which acts as a voltage regulator. When a transient voltage spike occurs, the diode will switch on and limit the voltage to its breakdown voltage (in this case, 85V). The diode acts like a valve, preventing the voltage from rising higher and protecting the system from damage. The SMP30A-M3/85A is designed with a high peak surge current rating and low let-through voltage so that it can tolerate short and powerful surges.

The SMP30A-M3/85A is particularly well suited for use in telecommunication and data communication systems, where it can provide protection against lightning-induced transients and other high-energy events. The diode can also be used to protect consumer electronic products from power surges and other unwanted voltage spikes. The SMP30A-M3/85A is an ideal choice for applications that require reliable protection against transient voltage spikes.
