SM5S10AHE3/2D

TVS (Transient Voltage Suppressor) diodes are used to provide protection from high voltage surges and transient spikes in the power supply. The SM5S10AHE3/2D is a 5 mm, 10 V TVS diode designed for high-speed ESD (electrostatic discharge) and surge protection applications. It has an ultra-low capacitance of 0.2 pF and an operating voltage of up to 10 V.

Application field: The SM5S10AHE3/2D is designed for use in high-speed ESD and surge protection applications in media and consumer electronics, such as digital cameras, CD ROMs, headphones, and other electronic devices. It can also be used for industrial-grade surge protection of control systems, communications systems, and high-speed signal lines. This device provides low leakage current for good protection from ESD, spikes, and EFT (electrical fast transient).

Working principle: The SM5S10AHE3/2D TVS diode is a solid-state device that reacts to overvoltage conditions by clamping the voltage to a predetermined breakdown level. When the voltage exceeds the diode’s clamping voltage, the diode begins to conduct, absorbing the excess energy and protecting the connected equipment. Once the surge is over, the diode reverts to its original state and the connected equipment resumes normal operation.

The device features a low dynamic resistance, which provides for faster response times in the event of a surge or ESD event. The ultra-low capacitance bit line and data line protection (BLP/DLP) allows for high-speed data lines to be protected with minimal signal loss. The SM5S10AHE3/2D also includes ESD protection up to ±15 kV (air discharge) to protect against ESD events.

In addition to surge and ESD protection, the SM5S10AHE3/2D includes protection from overvoltage conditions such as reverse polarity and accidental hot-swapping. The device features a low clamping voltage with a high peak pulse current capacity, making it suitable for a variety of applications.

The SM5S10AHE3/2D is an effective, stable, and reliable TVS diode for use in high-speed ESD and surge protection applications. It has an ultra-low capacitance of 0.2 pF and an operating voltage of up to 10 V, and offers protection from ESD events, EFT events, and overvoltage conditions. The device features a low dynamic resistance and low clamping voltage with a high peak pulse current capacity, making it ideal for a wide range of applications in the media and consumer electronics industries.
