LCE15A-E3/54

TVS diodes, otherwise known as Transil or Transient Voltage Suppressors, are semiconductor protection components used to protect electronic circuits from electrostatic discharge (ESD). They operate by diverting any fast, transient voltage overshoots to ground, thereby protecting other components in the system from damage. The LCE15A-E3/54 is a type of TVS diode is used to protect circuits from ESD and other transients. This article will discuss the application field of the LCE15A-E3/54 and its working principle.

Application field

The LCE15A-E3/54 is mainly used for protecting sensitive electronic components from ESD and other fast transients. It is designed to protect from overvoltage transients caused by ESD, inductive switching, and other voltage fluctuations. The device can handle up to 28 Volts with a low clamping voltage, so it can be used to protect low voltage circuits. The LCE15A-E3/54 is also suitable for automotive applications due to its high surge and peak pulse capability. It features a low capacitance, low leakage current, and low clamping voltage, all of which make it suitable for use in automotive applications.

Working principle

The LCE15A-E3/54 is a bi-directional TVS diode based on avalanche breakdown technology. When the voltage across the diode reaches its avalanche breakdown voltage, the diode begins to conduct, thus diverting any transient voltage spike to ground.
