SLD26U-017-B

TVS (Transient Voltage Suppressor) diodes are used to protect a circuit from voltage transients. The SLD26U-017-B is a member of the popular SLD14U-017 series of overvoltage protection diodes, which are designed to protect electronic circuitry from voltage transients that can occur as a result of inductive switching, cable discharge, and electrostatic discharge (ESD).

The SLD26U-017-B is a low capacitance TVS diode, is a unidirectional protection device designed to protect circuits from overvoltage transients that can be caused by lightning, electrostatic discharge (ESD), inductive switching, and cable discharge. The SLD26U-017-B is also able to provide ESD protection for I/O and USB lines in accordance with IEC 61000-4-2 (Level 4).

The SLD26U-017-B offers a robust design that is able to protect up to 1.2kW peak power at +15kV 8/20μs surge waveform. It is also able to provide protection against a wide range of transient voltages, from +25V to -33V. The SLD26U-017-B has a typical response time of less than 1ns (100ns for polarity reversing). The SLD26U-017-B also features a low leakage current, allowing it to be used in a wide range of applications, including automotive, industrial, medical, and consumer applications.

The SLD26U-017-B is ideal for use in applications such as automotive, industrial, medical and consumer electronics, IoT (Internet of Things) and many other applications. It can be used for protection against lightning and ESD on portable device I/O and USB lines, and provides efficient protection against overvoltage transients.

The working principle of the SLD26U-017-B is based on the principle of the zener diode. When the diode is exposed to a voltage greater than its rated reverse breakdown voltage, it begins to conduct current and lower the voltage to its rated clamping voltage. At this point, the diode allows the transient voltage to flow through it, diverting it away from the protected circuit.

The SLD26U-017-B is designed with an optimized construction, which includes a low capacitance PN junction and voltage limiting diodes. This results in an improved voltage clamping capability and lower parasitic capacitance. The device is also designed to be resistant to breakdown and thermal shock.

In summary, the SLD26U-017-B is a TVS diode designed to protect electronics from overvoltage transients. It offers robust protection for a wide range of applications and also features a fast response time and low leakage current. The SLD26U-017-B is ideal for use in applications such as automotive, medical and consumer electronics, and IoT due to its low capacitance and robust construction.
