TVS - Diodes

SMCJ11A series are surface mount Transient Voltage Suppression (TVS) Diodes designed for repetitive surge current applications. TVS diodes are a form of semiconductor that can provide burst protection for a device or system. It is used to protect semiconductor components and systems against high-energy, short-duration power transients such as Electrostatic Discharge (ESD) Voltage transients, lightning-induced surges, and induced load switching transients.

Application area

SMCJ11A diodes are mainly used to protect equipment from voltage or current transients. They can also be used in various applications such as automotive electronics, telecom, consumer electronics, and industrial electronics. These diodes can be used in automotive applications like Electronic Control Units (ECUs), Electronic Control Modules (ECMs), Invertors, Bearing Watchdog, and other electronic circuits.

These devices are also used in industrial applications like monitoring equipment, pumps, blowers, air conditioners, contactors, welding equipment, and laser systems. SMCJ11A diodes can also be used in devices such as computer motherboards, memory modules, hard drives, and other circuit boards in consumer electronics.

Working principle

The working principle of the SMCJ11A diode is based on the phenomenon of avalanche breakdown. When the reverse voltage across the diode reaches a certain level, the internal electric field reaches the breakdown point and the current between the diode electrodes increases dramatically. This is known as breakdown and avalanche breakdown. This phenomenon can be used to reduce the electric stress on a sensitive component.

When a high-energy transient is applied between the anode and the cathode of the SMCJ11A diode, the increased electric field intensifies the free electrons and holes inside the diode. This quickly increases the current inside the diode, lowering the voltage and dissipating the energy from the transient. This method of voltage suppression is known as clamping.

SMCJ11A diodes are designed to be robust. They have low leakage at normal voltage levels and low clamping voltage levels. This makes them suitable for applications where low voltage is needed, and for long-duration surges.
