TVS diodes (transient voltage suppression diodes) are components used to protect circuits from transient voltage waves. These components help in maintaining the integrity of high-speed signal inputs and outputs, and are also capable of protecting voltage circuits from unexpected transients in power. SMCJ85C-E3/9AT is a series of TVS diodes from WE Corporation – a leading manufacturer in the semiconductor industry.

The SMCJ85C-E3/9AT series of TVS diodes are ideal for use in high-speed data lines, LCD driver circuits, and other sensor circuits where voltages may become unstable due to changes in environment or circuit conditions. These components provide protection for bidirectional electrostatic discharges (ESDs) of up to 15kV (human body model, HBM), and can also protect circuits from unwanted surges caused by load dump or inductive load switching. These components are also designed to reduce the flow of transients on both sides of the circuit.

These TVS diodes come in a variety of package styles and current ratings, ranging from 30V to 85V and from 400mA to 1000mA. The case forms available for this series include SURFACE MOUNT DO-214AA, and SURFACE MOUNT DO-214AC. With a low-capacitance diode, a fast response time of less than 1ns is achieved and the ESD protection is maximized. This series has also undergone several rounds of testing in order to guarantee high-performance levels with static tests, dynamic tests, and ESD tests.

The design of the SMCJ85C-E3/9AT series of TVS diodes follows the principle of avalanche breakdown. This phenomenon occurs when the electric field becomes so strong inside the diode that it causes the electrons to accelerate and collide with the atoms of the material, releasing additional electrons in the form of a current. This current will then be diverted away from the circuit, protecting it from the damage caused by transients and surges.

A key feature of this series is its peak pulse power dissipation of 1.7kW. This power is capable of handling transients up to 1.2kW, providing reliable protection for a wide range of electrical components and electrical circuits. Additionally, the SMCJ85C-E3/9AT series has a clamping voltage of 140V, as well as an operating temperature range of -55°C to +150°C.

In conclusion, the SMCJ85C-E3/9AT series of TVS diodes from WE Corporation is an ideal choice for those looking for reliable protection for a range of circuits and components. The devices are capable of protecting voltage circuits from transients in power, while also providing protection for bidirectional electrostatic discharges and reducing the flow of transients on both sides of the circuit. Moreover, the peak pulse power dissipation of 1.7kW and the clamping voltage of 140V ensure the devices will provide effective and reliable protection for all electrical components.
