1.5KE400A-E3/54

TVS-Diodes

The 1.5KE400A-E3/54 is a Silicon-Avalanche Diode (SAD) specifically designed to protect sensitive electronic components from electrical transients. It is typically used for electrical transient suppressions in consumer and communication electronics, industrial and automotive electronic applications, and high-speed computer and telecom systems.

Application Field

The 1.5KE400A-E3/54 is a high-speed Transient Voltage Suppressor (TVS). TVS diodes suppress transient voltages from lightning and other spikes on systems by shorting them to ground or by maintaining them within a safe range. TVS diodes protect communication systems, automotive body and charging systems, and consumer electronics, such as cell phones and computers, from high-energy transients.

Working Principle

The 1.5KE400A-E3/54 is designed to shunt away high-voltage transients by operating as a “crowbar” circuit to ground. In the event of a transient, the internal Silicon Avalanche Diode (SAD) rapidly switches between on and off states thus shorting out the transient surge current to ground.

The 1.5KE400A-E3/54 is designed to withstand voltages up to 400 volts, with a peak pulse surge current of 400 amperes. It is available in a 0805 package and has a clamping voltage of 7.4 Volts.

The device is designed to work in a variety of system environments, and it is stable from -55 degrees Celsius to 125 degrees Celsius. The device also features a wide operating temperature range, low turn-on capacitance, and a low operating voltage, making it suitable for use in systems running sensitive data.

Conclusion

The 1.5KE400A-E3/54 is a Transient Voltage Suppressor specifically designed to protect sensitive electronics from electrical transients. It is typically used in a variety of system environments, and its features make it suitable for use in systems running sensitive data. Additionally, the device has a wide operating temperature range, low turn-on capacitance, and a low voltage.
