MXRT 100KP70CA is a diode in the Transient Voltage Suppressor (TVS) family. It is commonly used in telecom and computing applications to protect against damaging Glitches, ESD, and EFT. This diode is well suited for high temperature applications, making it very attractive for engineers needing robust over-voltage protection in harsh environments.

A TVS is a three-terminal, bi-directional device used primarily to protect sensitive electronic circuits from voltage transients induced by lightning or other type of electrostatic discharge (ESD). The MXRT 100KP70CA is a very popular and highly acclaimed TVS due to its ability to clamp voltages from transients as high as 70V, reverse standoff voltage of 100V and ESD clamping voltage of up to 400V.

State-of-the-art MOSFET process technology was employed for the MXRT 100KP70CA. This process ensures improved performance, and improved reliability of the device at high temperatures. Silicon abrasion protection technology of the MXRT 100KP70CA enables slow voltage ramp-up of ESD transients, which minimizes the damage to the sensitive electronic circuitry from ESD and EFT.

The MXRT 100KP70CA is designed with unidirectional ESD protection for data and high speed signal lines, eliminating the risk of latch up due to a simultaneous bidirectional ESD strike. The low clamping voltage is key in this diode because it ensures the sensitive circuitry does not experience over-voltage damage during a voltage transient. The MXRT 100KP70CA provides excellent ESD and EFT protection, high temperature operation and low cost performance in a wide variety of end user applications.

The MXRT 100KP70CA application field includes laptop computers, DSL / modem, military installations, PDA, routers, wireless networking equipment, PDAs, and ZIF interface applications. Due to its low clamping and reverse standoff voltages, the MXRT 100KP70CA can also be used in applications where design engineers need to reduce the amount of transient voltage clamp needed to protect the sensitive circuitry of the device. Many standard and proprietary applications also can use this diode due to its ability to handle higher voltage transients common in low-voltage, high-speed signal line applications.

The MXRT 100KP70CA working principle requires three functional blocks; a Zener diode, an avalanche diode, and Ground. The Zener diode shunts excess current for transient events, and the avalanche diode clamps the voltage during electrostatic discharge or EFT. The Ground terminal provides the return path for the current. An avalanche diode creates a potential barrier in the Zener region and clamps the voltage by sinking the excess current from the reverse direction. An avalanche device is normally a PN junction, positioned to curve the voltage coordinate during an electrostatic discharge.

In summary, MXRT 100KP70CA is a great choice for engineers seeking robust over-voltage protection for their high temperature applications. Its low cost, state-of-the-art process technology, and low clamping voltage makes it an attractive option for a wide range of applications. It provides excellent ESD and EFT protection and the unidirectional ESD protection helps to eliminate the risk of latch up. With its low clamping and reverse standoff voltages, the MXRT 100KP70CA can also be used in applications requiring lesser amount of clamping voltage to protect the sensitive circuitry from voltage transients.
