VTVS12ASMF-HM3-18

Transient Voltage Suppression (TVS) diodes are a type of solid state semiconductor device designed to protect electronic components from electrical and electrostatic over-voltage transients which can occur on power lines, communication cables, inputs and outputs, and radio-frequency (RF) circuits. The VTVS12ASMF-HM3-18 is a component of the TVS diode family and is specifically designed for the 12V applications.

The VTVS12ASMF-HM3-18 is a monolithic, low capacitance, and bidirectional tvs diode with a stand-off voltage of 17.8 volts. This component is capable of handling peak pulse currents up to 5.0A and is provided in a surface mount epoxy package. It is constructed with two low capacitance Zener diodes, a common anode and an isolated cathode, which are connected in parallel and provide a fast switching shunt to safely protect against ESD (electrostatic discharge) or other transients. Additionally, the VTVS12ASMF-HM3-18 can be used as a high-speed ESD protection for wide-band RF signals.

This component can be used in 12V telecom and computer applications as well as for ESD/transient suppression on power and signal lines in other high voltage environments. The VTVS12ASMF-HM3-18 has an integrated ESD protection circuitry and an internal ESD rating of up to 8kV minimum, ensuring ideal ESD protection.

In terms of its mode of operation, the VTVS12ASMF-HM3-18 works in two ways. Firstly, it has a high surge current clamp circuit that can down bend the voltage spike. Secondly, its low capacitance element shunts transients by acting as a fast switching shunt between power lines on power-surges and ESD events. This component is designed to protect sensitive electronics from transient voltage which can cause serious damage and degrade system performance, and also to ensure reliable operation of the device and minimize system downtime.

The VTVS12ASMF-HM3-18 offers reliable, fast-recovery, bidirectional protection from both ESD and transient voltage surge events. It is capable of handling peak pulse currents up to 5A and offers superior suppression capability for transient events and switch inductive transients. As a highly integrated component, the VTVS12ASMF-HM3-18 provides excellent ESD performance while maintaining low capacitance to reduce interference with high frequency signals.

The VTVS12ASMF-HM3-18 is a versatile component which can be used for transient and ESD protection in many different applications. Its high surge current clamp circuit and low capacitance elements allow it to provide effective protection from transient voltage and electrostatic discharge. It is suitable for 12V applications in telecom, computer, high voltage, and power and signal line protection, making it an ideal component for ensuring safe, reliable operation of sensitive electronic devices.
