MXSMLJ85CAE3 Datasheet/PDFMXSMLJ85CAE3 TVS - Diodes
Transient Voltage Suppressor (TVS) diodes are immensely important components that, when used in a device, can prevent power spikes from damaging the device’s internal circuitry. The most common type of TVS is the diode-based TVSs which are formed when a diode is reverse-biased and configured with an external resistor. The MXSMLJ85CAE3 is one such device. This diode feature bidirectional ESD protection and is designed to defend against electrostatic discharges of up to 25kV.
Applications
The MXSMLJ85CAE3 TVS Diode is a great choice when it comes to high-speed data signals as it offers a fast response time and an extended surge protection for I/O lines. As a result, these types of diodes are typically used to protect against electromagnetic interference and power or current surges in electrical circuits. TVS-diodes are also commonly used in automotive applications, such as truck lighting and blinkers, dashboard components, sensors and shifters. Additionally, they are popularly used in consumer electronics such as laptops, printers, gaming consoles, smartphones, and tablets.
Working Principle
The MXSMLJ85CAE3 TVS diode works by clamping the voltage across its terminals when the voltage reaches the diode’s breakdown voltage. When an electrical spike occurs, the added voltage exceeds the diode’s breakdown voltage and causes the diode to turn on. The excess current is then conducted through the diode and dissipated as heat. This protects the circuit from any further voltage surges. The MXSMLJ85CAE3 TVS diode features a low on voltage, which ensures that it turns on before it gets too hot and is destroyed by overcurrent conditions.
Conclusion
In closing, the MXSMLJ85CAE3 is a type of diode that is designed to protect devices and circuits from power or current surges. These diodes are ideal for high-speed data signals and are commonly used in automotive applications and consumer electronics. The diode features a fast response time and an extended surge protection for I/O lines. The diode works by clamping the voltage when it reaches its breakdown voltage, thus conducting excess current through the diode and dissipating it as heat.
