TVS (Transient Voltage Suppressors) diodes are used to protect sensitive electronic components from transient voltage events. The SMLJ8.5AE3/TR13 is a particular type of TVS diode. It is designed to protect devices from electrical transients caused by input port and circuit board stress events. This article will discuss the application field and working principle of the SMLJ8.5AE3/TR13.

The SMLJ8.5AE3/TR13 is suitable for active and passive ESD protection in medium-current applications. It is particularly well suited for use in high-speed data lines such as USB 3.0, HDMI and USB 2.0. The diode also provides excellent protection for power supply lines in telecom equipment, general electronics and automotive applications. The TVS diode can be used in either a bidirectional or unidirectional configuration.

The SMLJ8.5AE3/TR13 is a fast-recovery diode that is designed to clamp transient voltages quickly. The diode has a fast response time that will respond to high-speed transients in as little as 5 ns. The SMLJ8.5AE3/TR13 also has excellent clamping performance. The diode will protect sensitive devices from overvoltage transients up to ±8.5kV (Contact), ±8.1kV (Air), and maximum peak pulses currents up to 18A. The diode also has an operating temperature range of -55°C to 150°C.

The working principle of the SMLJ8.5AE3/TR13 is relatively simple. The diode is comprised of two main components; the voltage clamp and the current clamp. The voltage clamp is designed to clamp incoming transient voltages to a safe level by providing a low impedance path to ground. The current clamp is designed to limit the surge current that can flow through the diode. When a transient voltage is applied, the voltage clamp will quickly clamp the voltage to the safe levels while the current clamp will limit the peak current that can flow through the diode. When the transient event is over, the diode will return to its normal operating state.

In summary, the SMLJ8.5AE3/TR13 is a fast-recovery TVS diode that is designed for active and passive ESD protection in medium-current applications. The diode is suitable for use in high-speed data lines such as USB 3.0, HDMI and USB 2.0, as well as power supply lines in telecom equipment, general electronics and automotive applications. The diode has a fast response time and excellent clamping performance, which will protect devices from overvoltage transients up to ±8.5kV (Contact), ±8.1kV (Air). The operating principle of the SMLJ8.5AE3/TR13 is based on the voltage and current clamping components which quickly clamp transient voltages to safe levels, and limit the surge current that can flow through the diode. All in all, the SMLJ8.5AE3/TR13 is a reliable and versatile solution for the protection of sensitive electronic components from transient voltage events.
