The SMLJ7.5A is a bidirectional voltage clamping device in the TVS (Transient Voltage Suppression) Diode family and is designed to protect against strong ESD/EFT pulses or other voltage upsurge. This diode is suitable for widely used USB applications. SMLJ7.5A diodes have variety of properties.

Typical applications for the SMLJ7.5A include ESD protection for any data lines requiring suppression of up to 8kV Human Body Model, EFT protection for data lines requiring suppression of up to 800V, and overvoltage protection for any low voltage line; USB ports, PCI ports and audio/video ports.

The maximum breakdown voltage of SMLJ7.5A can reach 7.5V, and the clamping voltage is lower than 10V. It can clamp voltage up to 5A with peak pulse power 8.3W. The Stand-off voltage can reach 2.4V.It also has low operating capacitance of 5pF. SMLJ7.5A has fast response time (less than 1ns) and tight clamping which can protect against overvoltage.

The SMLJ7.5A primarily works in a manner of voltage clamping. It works by preventing high-level transients from entering the protected circuit. If an undesirable pulse voltage exceeds the breakdown voltage, then the diode applies a reverse voltage across the diode, clamping and limiting the voltage to the zener voltage.

The internal construction of the SMLJ7.5A is a junction of two diodes which is designed for excellent protection of high surge current. The reverse leakage current of the device is low in order to further the protection offered. The operating temperature range of the diode is -55 to 125 degrees Celsius with the absolute maximum peak power of 8.3W.

In summary, the SMLJ7.5A is a TVS diode which is used for many applications such as ESD, EFT and overvoltage protection. It has low operating capacitance and a a maximum breakdown voltage of 7.5V with a clamping voltage of less than 10V. The fast response time and tight clamping protects against overvoltage and surge current. Moreover, with an operating temperature range of -55 to 125 degrees Celsius and an absolute maximum peak power of 8.3W, SMLJ7.5A is one of the most reliable choices on the market.
