TVS - Diodes are used in a variety of applications ranging from data communication systems to consumer electronics. The Toshiba TPC22HM3/87A is a uni-polar, high-speed, low-capacitance transient voltage suppressor designed to protect electronic systems from voltage spikes and over-voltage events. With its high peak pulse current capability and low capacitance, the TPC22HM3/87A is ideal for protecting communication lines from ESD, lightning, and other transient voltages.

The TPC22HM3/87A is a solid-state device that utilizes a silicon avalanche diode, in combination with a low-capacitance, high-frequency, non-linear junction, to provide high-speed protection against transient events. In the event of an over-voltage or voltage spike, the TPC22HM3/87A will begin to conduct at a specified voltage level, limiting and/or diverting the transient current away from the protected device. The avalanche diode begins to turn on at a particular voltage level and then becomes fully on at a higher voltage level. During steady state operation, the TPC22HM3/87A will remain in a low-impedance state, allowing the protected device to operate normally. As the transient voltage rises above the predetermined threshold, the diode will conduct, and the voltage across the protected device will be clamped to the predefined voltage level of the TPC22HM3/87A.

The TPC22HM3/87A can also be used in applications that may require limited protection. The device can be employed to reduce high-frequency noise and transients, while also limiting the applied voltage or current to the protected circuitry. Additionally, the low capacitance of the TPC22HM3/87A helps to ensure that data transmission is not significantly affected by the presence of the protection device. Applications for the TPC22HM3/87A include protection of PCB traces from ESD, surge protection for laptop computers, I/O protection for instruments and data communication systems, and the protection of portable electronics from power surges.

In summary, the Toshiba TPC22HM3/87A uni-polar transient voltage suppressor is an ideal choice for protecting a broad range of electronic systems and circuits from voltage spikes and over-voltage events. With its high peak pulse current capability, low capacitance, and low impedance, the device is well suited for protecting sensitive components from transients, while helping to maintain signal integrity and improving system reliability.
