Transient voltage suppressor (TVS) diodes are used in various electronic devices to protect against voltage spikes. The ICTE10C-E3/51 is a TVS diode particularly suited to applications in harsh environments and extreme cases. In this article, we will take a look at their application field and working principle.

The ICTE10C-E3/51 is an unidirectional 10V transient voltage suppressor diode designed to protect sensitive electronic components in a wide variety of applications. It uses a dual-slot structure to dissipate heat generated by its unique silicon avalanche technology. This technology, combined with a high peak power rating, is capable of over-voltage protection and instantaneous turn-off time of less than 100ns, making it suitable for applications in harsh environments. It also features small size, low capacitance, and low leakage current. Furthermore, its peak forward surge capability can be up to 600W.

This TVS diode also offers a wide operating temperature range from -55°C to 175°C, making it suitable for a variety of application fields, including automotive, industrial, computer and digital opportunities, instrumentation, telecommunications, and aerospace. It is also suitable for railway operation and safety-critical applications. The ICTE10C series is designed to comply with both industrial and automotive component standards.

The ICTE10C-E3/51 is designed to protect sensitive electronic components from voltage transients caused by lightning strikes, static discharge, line surges, and other power disturbances. The diode works by diverting the surge current away from these components and safely dissipating it into the ground. It has a maximum breakdown voltage of 10V, with a working clamping voltage at 5.8V.

When a surge is detected, the avalanche process in the silicon chip is triggered, allowing it to absorb the energy of the transient and clamp the voltage applied to the protected components. The process involves the formation of a high number of electron-hole pairs, which can then be rapidly neutralized. This avalanche process is inherently fast and it helps maintain the transient peak voltage at a safe level.

In addition to over-voltage protection, other features of the ICTE10C-E3/51 include a high surge capability, small size, low EMI noise, and low leakage current. It is suitable for use in high-density PCB assemblies and is compatible with high-temperature SMT processes. The improved surface mount version of this diode is also available for increased power handling capabilities.

The ICTE10C-E3/51 is a high-performance, reliable, and cost-effective TVS diode. Its combination of low capacitance, low leakage current, and fast turn-off time make it suitable for various applications in harsh environments. Additionally, its wide operating temperature range and high peak power capability make it suitable for a variety of applications. Thus, the ICTE10C-E3/51 is the ideal choice for any electronic system that needs protection from over-voltage transients.
