The TPC22AHM3/86A TVS diodes are a type of overvoltage protection device employed to protect items such as power supplies, data lines and other electronic components. It is designed to protect against both electric current and voltage transients, providing a high current protection level of approximately 1900A peak. The TPC22AHM3/86A is ideal for applications where small size and low profile are important factors. As a Transient Voltage Suppressor diode, it is designed to prevent the device and circuit it is protecting from damage due to overvoltage transients and ESD (electrostatic discharge).

The TPC22AHM3/86A ’s working principle is that when it senses a voltage higher than the breakdown voltage, it will become briefly conductive, allowing some of the excess charge to pass through the body of the diode. This is due to the fact that when an electric field is applied across the junction of two different semiconductor materials, a charge will begin to flow. When the excess charge passes through the diode, it will reduce the voltage across the junction and limit the current, thus protecting the device from damage.

The operating voltage of the TPC22AHM3/86A varies between 8.5V and 20V and the peak surge current rating is 5.5A (2/10 microseconds). The TPC22AHM3/86A comes in several packages and sizes and has a low-clamping voltage, which improves its suitability for applications requiring low voltage protection. The TPC22AHM3/86A has a center insulating washer which increases the protection level for applications requiring extra safety.

The application fields of TPC22AHM3/86A TVS diodes cover a broad range, such as telecom, data lines, consumer electronics, automotive, and industrial electronics. This device can be used to protect a variety of digital and analog circuits and components. It is especially suitable for applications that require high reliability, such as those used in automobiles, medical equipment, and military electronics.

The TPC22AHM3/86A is a reliable and cost-effective solution for protecting against electric current and voltage transients. With its small size, low profile, and its flexibility in terms of application fields, this TVS diode is the ideal choice for providing cost-effective protection for a wide range of devices and circuits.
