SMF7.5A-T13 is a kind of TVS diodes which is widely used in consumer electronic products, cable protection applications and a variety of automotive applications. It is designed to protect equipment, power supplies, data lines and printed circuit boards from damage due to overvoltage pulses caused by transient voltages and is used to protect against surges such as those caused by lightning strikes, accidental contact with power lines, electrostatic discharge, and more.

The SMF7.5A-T13 is a bidirectional TVS diode with a breakdown voltage of 7.5 volts, and a working temperature range from -55°C to 125°C. This device has an ultra-low capacitance of 0.095 pF and can handle up to 1500 Watt of peak pulse power. It features an 1.25 amp hold current rating with and a maximum clamping voltage of 15 volts, making it ideal for protecting sensitive circuitry against voltage transients.

The working principle of the SMF7.5A-T13 is to protect the circuit from the damaging effects of transient voltages. When a voltage pulse greater than the breakdown voltage is applied, the diode will conduct current, thus shunting any additional voltage to the ground line and protecting the circuitry. The device is capable of dissipating much of the energy from the voltage spike, significantly reducing the overvoltage before it reaches the precious semiconductor devices.

The SMF7.5A-T13 is available in a variety of packages such as the SOT-23, SOT-323, SC74, SOD-123, SOT-89 and TO-92. Its small size, low profile and low capacitance, along with its excellent protection capability, make it ideal for use in a wide range of applications such as consumer electronics, cable protection, automotive, and industrial.

In conclusion, SMF7.5A-T13 is an ideal solution for protection against transient voltage pulses in high frequency systems. This TVS diode exhibits excellent surge protection capability, low capacitance, a breakdown voltage of 7.5 volts, and is offered in a variety of packages to suit any application.
