1.5KE120ATR

1.5KE120ATR is a type of TVS - Diodes (Transient Voltage Suppressors). It is designed to protect electronic circuits against damages caused by high voltage transients. A 1.510KE120ATR diode is designed to protect against voltage transients that range from 5V up to 18V. It is constructed with the use of an ultra-thin film (UTF) technology that ensures high insulation resistance (IR) and low leakage current (IL). 1.5KE120ATR is mainly used in on-board devices, such as computer, mobile phone, USB port, I/O power supply and other electron products which have risk of being damaged by ESD.

1.5KE120ATR application field and working principle:

1.5KE120ATR is a uni-directional TVS diode. It is mainly used in ESD protection, induced by electrostatic discharge. Its working principle is simple, when an ESD rises above the rated voltage of the diode, it will respond immediately and start to conduct. Once the voltage drops below its breakdown voltage, the diode will automatically turn off and protect the circuit from further damage. In addition, the 1.5KE120ATR diode also has low clamping voltage and good dynamic characteristics, which can effectively prevent the flow of surge current.

The application field of 1.5KE120ATR includes:

• Automobiles: To protect electronic systems in automobiles, such as airbag control modules and ABS.
• Computer: 1.5KE120ATR is used to protect electronic systems and peripherals, such as motherboards, CD-ROMs, network cards, etc.
• Communication systems: It is used to protect the communication systems from ESD induced damage, such as 3G/4G telecom equipment and network switches.
• Industrial equipments: To protect industrial equipments from ESD and short circuit, such as servo, motor controllers, I/O modules, etc.
• Consumer electronics: 1.5KE120ATR can be used in various consumer electronics, such as Bluetooth devices, USB port, chargers, printers, digital camera, etc. It can provide effective ESD protection.

With 1.5KE120ATR diode, it is possible to reduce the risk of ESD induced damages to electronic systems in different application fields. It is designed to provide fast response to high voltage transients, enabling it to protect the system within a shortperiod of time. Furthermore, its low clamping voltage also ensures that it does not cause further damages to the system during the protection process.
