The TPSMD78CA is an efficient bidirectional TVS-Diode device from the TPSMD78CA family, realized by Texas Instruments in their latest TPSMD78CA technology, which combines a surge protection diode with an efficient breakdown voltage protection element. The device works by protecting circuits and devices against voltage surges caused by power switching, lightning strikes, and electrostatic discharge. The TPSMD78CA offers a wide range of features and benefits, including:

• Breakdown voltage range from 1.5V to 8V
• Voltage clamping from 21V to 46V
• Maximum operating temperature of 125
• Very low operating current of 12mA@7V
• Robust structure for ESD and surge protection capability
• High surge handling capability

The TPSMD78CA is a solution ideal for a wide variety of applications, including automotive, military, telecommunications, and consumer electronics. The device is designed to protect wireless systems, transistors, memory devices, power application systems, and other high-speed switching systems. As a TVS device, the TPSMD78CA operates by providing an abrupt voltage drop when the supply voltage exceeds the voltage clamping level. The device can be connected directly to the power line, bypassing any additional components or components that typically require series inductors and parallel RC network.

The TPSMD78CA offers high surge handling capability, with peak pulse and mean working power ratings up to 2000W and 800W respectively. The device also features low leakage current of 0.5mA@7V and high ESD protection of up to ±4.5kV. Its electrical operation effective window is from -55°C to 125°C. With its high operating temperature, the TPSMD78CA can be used in industrial and automotive applications, where reliability and performance are required.

The TPSMD78CA is a bidirectional device, which means it is able to handle excessive current in both directions, providing strong protection from both overvoltage and short-circuits. In addition, the TPSMD78CA has low capacitance of 1.5pF to ensure minimum interference with signal and data paths.

Overall, the TPSMD78CA offers a versatile and effective protection solution for a wide range of applications. With its high surge handling capability, low total capacitance, low leakage current, and wide operating temperature range, the TPSMD78CA is highly suitable for keeping the system protected at all times.
