TVS (transient voltage suppressors) – diodes are a protective component that safeguards a circuit against voltage transients from sources such as power line surges or electrostatic discharge (ESD). The SMP22-M3/85A is one such device, designed to protect high-speed digital and analog signals against overvoltage conditions of maximum of 8.5V.

The SMP22-M3/85A consists of two silicon vertical-structure diodes connected in series: the MOS-trigger and the Zener breakdown diode. The MOS-trigger terminal is connected directly to receive the external signal. The second terminal connects to the circuit being protected. When a strong surge or ESD events occur, the MOS-trigger terminal depletes very quickly, turning cycles the Zener breakdown diode. This activates the Zener breakdown diode, which is clamped at the zener voltage. This limits the voltage transient across the SMP22-M3/85A.

The SMP22-M3/85A is ideal for use in industrial automation, telecommunications, and other applications where ultra-rapid breakdowns are needed. The device’s response time of less than 25 nanoseconds to a eight volt overvoltage condition makes it suitable for RF, EMI, and similar applications. The device also has an excellent long-term reliability, making it the perfect choice for a variety of applications.

The SMP22-M3/85A has a wide operating temperature range of -55°C to 150°C, which allows it to be used in a variety of temperature extremes. The device’s low capacitance ensures that it will not interfere with the signal integrity of the protected circuit. In addition, the SMP22-M3/85A has a high tolerance to fast line transients, making it an excellent choice for protecting high-speed data signals from interference.

The SMP22-M3/85A is a lightweight device that is easy to mount and requires minimal board space. The device also has built-in overvoltage protection, providing additional protection against voltage transients. The device’s low leakage current and clamping voltage also make it a reliable choice, even when subjected to extreme temperatures and long-term use.

In addition, the SMP22-M3/85A has a low reverse leakage current, so it can be used with low-noise circuits. The device’s low profile and surface mount make it an excellent choice for prototyping and other space-constrained applications. The low capacitance of the device and its excellent long-term reliability make it the perfect choice for a variety of applications.

Overall, the SMP22-M3/85A, is an excellent choice for transient voltage suppressors. Its ultra-rapid response time and low capacitance make it an ideal choice for high-speed digital and analog signals, as well as embedded designs. The device’s excellent reliability and temperature range also make it an ideal choice for long-term applications.
