TVS (transient voltage suppressor) are one of the most common types of diodes in use today. A TVS diode is a reverse-biased, high current handling, semiconductor device designed to protect sensitive electronic components from transient overvoltage events. The MXLSMLJ26AE3 is a unidirectional, two-terminal, low-voltage transient voltage suppressor (TVS). It is designed to protect sensitive electronic components from destructive high transient voltage events.

Application Fields: MXLSMLJ26AE3 is commonly used for over-voltage protection of switch mode power converters, power supplies and downstream circuit protection. Thanks to its excellent capability to withstand surge voltage events, this device is ideal for use in automotive applications such as body electronics, entertainment systems and power management. It can also be used to protect lines against electrostatic discharge (ESD) or lightning-induced surges.

Working Principle: Under normal conditions, the device acts just like a standard diode. When it meets a voltage surge, it instantly conducts and redirects the current. This short-circuits the transient surge, protecting the device from any damage. MXLSMLJ26AE3 provides very low clamping voltage, optimized for surge protection in a wide range of applications including power supplies, microprocessors, I/O ports, cable protection, and automotive applications. The device is Specifically designed to use external capacitors to form a low series resistance and low capacitance filter.

MXLSMLJ26AE3 also provides efficient thermal and dynamic characteristics such as a low dynamic resistance, low leakage current, high peak pulse current, and self-restoration after the surge event. This TVS Diode is rated for a maximum peak pulse power of 1500 Watts and its peak pulse current rating is 6.3 A. With a metal case and plastic case top, the device offers an operating temperature range of -55°C to 150°C. This product is reflowable up to 260°C.

To ensure the best protection for any component, it is recommended that users consult with a technical expert to understand their power supply topology and select the appropriate ratings for their application. Ideally, an externally mounted TVS diode should be used, in addition to internal TVS devices for gate protection and primary EMI protection. This will provide an optimal circuit protection solution.
