The V385LU40CPX10 is an ultra-high-energy-density transient-voltage-suppression (TVS) diode developed by ON Semiconductor Corporation, which can safely clamp transient energy over a broad spectrum of frequencies. As a part of their wide portfolio of varistors, MOVs, and TVS diodes, this TVS diode is designed to protect sensitive electronics from voltage transients.

Application Field

The robust V385LU40CPX10 is suitable for a wide array of applications. It can provide reliable protection against highly destructive voltage transients over a broad range of frequencies, making it ideal for automotive, industrial, and consumer electronics applications. This device is characterized at 82A peak pulse current with 8/20 µs waveform. The V385LU40CPX10 can also be used in stabilizing power supply lines, providing protection against lightning strikes, and surge suppression.

Working Principle

The V385LU40CPX10 is based on the unique silicon-oxide technology of ON Semiconductor Corporation that offers high energy density and high peak current levels in a compact package. The device absorbs and dissipates excess transient energy by clamping or shunting voltage above a predetermined breakdown level. It will instantly divert the excess current through a low-resistance conduction path and allow normal operation of the system once the surge has been addressed. This gives superior protection to sensitive electronic components from the damage caused by excessive voltage transient.

In addition, this device has high surge-handling capability in a very small package and excellent clamping performance due to its low maximum clamping voltage. The V385LU40CPX10 also offers fast response time and good current handling capability, making it suitable for general-purpose applications such as control lines, I/O lines, and coaxial cables.

Conclusion

The V385LU40CPX10 is ideal for automotive, industrial, and consumer applications that require high energy density and superior surge-handling capabilities. It has an ultra-high energy density and excellent peak pulse current capacity that eliminates the need for external protection components. The device has high surge-handling capability in a very small package and excellent clamping performance due to its low maximum clamping voltage. With fast response time and good current handling capability, the V385LU40CPX10 is the perfect choice for protecting sensitive electronic components.
