TVS (Transient Voltage Suppression) diode technology has been used for decades to protect sensitive electronics from overvoltage events in automotive, industrial, medical and military applications. The TVS diode can absorb high voltage transients and overvoltage events such as electrostatic discharge (ESD), power line surges, lightning strikes and EMI/RFI. The V385LA40CPX10 is a mid-range, low capacitance, unidirectional three terminal TVS diode that offers superior performance in protection against ESD.

The V385LA40CPX10 is designed to protect sensitive electronics from overvoltage events and is ideal for applications such as adapters, automotive, computers, consumer electronics, industrial systems, telecom, and other systems that require low capacitance in high speed data lines. The low capacitance of this diode allows it to be used to limit voltage surges at high data transmission speeds while also providing excellent surge current capabilities. The temperature characteristics of this diode are stable across the wide temperature range and allow for broad-temperature application usage.

The V385LA40CPX10 features an ultra-low capacitance of 0.50pF and a high peak pulse power rating of 400W, making it suitable for a variety of applications. The fast response time of this diode allows it to be used to protect circuits from overvoltage transients that occur without warning. The diode is reverse power limited to 1.0V, which makes it suitable for shutdown protection when the power supply is unintentionally short-circuited or reversed-biased.

The V385LA40CPX10 is designed with a single-column protection structure that prevents an additional breakdown of the protection diode and provides continuous protection against overvoltage transients. It also has an extremely low junction capacitance which reduces any negative effects on signal performance that could arise during high-speed switching applications. Additionally, the low weight and small package size makes it easy to integrate the V385LA40CPX10 into the circuit.

The working principle of this diode is based on bi-directional protection principle. With this principle, the current is blocked from traveling and the protection diode will limit the voltage to the set limit of the designed breakover voltage. This diode features an avalanche voltage of 10V and a breakover voltage of 22V. When an overvoltage transient or ESD occurs, the diode will instantly absorb the excess voltage thus providing the protection.

The V385LA40CPX10 is an ideal combination of low capacitance, high surge power rating and fast response time. This combination makes the diode the perfect choice for a variety of applications. It provides superior protection against overvoltage transients while keeping line noise to a minimum. With its small size and high reliability, this diode is an excellent choice for a variety of applications that require fast and reliable protection.
