MASMLG18CA TVS - Diodes
The MASMLG18CA is a part of the Transient Voltage Suppressor (TVS) - Diodes series, developed by Vishay. It’s a high efficiency, unidirectional device intended for use in various areas of electronics, including consumer electronics, automotive, and defense. This type of component is designed to protect circuits against transient voltage spikes caused by electrostatic discharges (ESD) or electromagnetic interference (EMI). It’s well suited for applications with high levels of surge current or voltage. The MASMLG18CA is a surface mount device with an envelope size of 17.1 mm by 7.5 mm with a 5.0 mm pitch. It features an operating temperature range between -65°C and +150°C and a voltage rating of 6.0V to 18.0V. The MASMLG18CA is a bidirectional device, meaning it can both absorb and pass current in either direction. It has an extremely low dynamic resistance, which allows high ESD protection levels to be reached. It also features a significant capacitance, making it a reliable and cost-effective solution for ESD protection in a number of applications. The main working principle of the MASMLG18CA is that it extracts and dissipates surplus energy from incoming spikes, thus effectively protecting the circuit it is connected to. When there is an ESD or EMI event, it creates a voltage gradient, which causes the electric field in the junction region of the diode to increase. This leads to a spark which causes the breakdown of the diode. The MASMLG18CA\'s bidirectional design makes it suitable for most EMI environments. Its level of protection against ESD is classified as per the IEC 61000-4-2 standard. It is capable of providing up to 15 kilovolts in ESD protection, as well as up to 30 amps of surge current protection. The MASMLG18CA is also capable of passing a wide range of DC bias currents, so it can easily handle the load conditions present in most applications. Its flexibility and cost-effectiveness make it an excellent choice for high reliability applications. Overall, the MASMLG18CA is an excellent choice for a range of applications, particularly those with high levels of ESD and EMI protection requirements. Its combination of flexibility, reliability, and cost-effectiveness make it a strong contender in the ESD protection market.
