TVS (Transient Voltage Suppressors) diodes are designed to protect sensitive electronic components from transient overvoltage events, such as Electrical Fast Transients (EFT), bursts, surges, lightning, electrostatic discharges (ESD) and short circuits. They are also commonly used in Automotive, Military, Aerospace, and Telecommunications applications. SMDA15C-5.TBT is a 5-pin surface mount TVS diode designed for protection against ESD and other overvoltage events. In this article, we will discuss the application field and working principle of SMDA15C-5.TBT.

Application Field

SMDA15C-5.TBT can be used in a wide variety of applications, including automotive and industrial electronics systems. In addition to its high-performance capabilities, SMDA15C-5.TBT also offers excellent protection from ESD, lightning, and other transient overvoltage events. In automotive applications, it can be used to protect the wiring harness, and serves as an ESD protection device for ECU (electronic control units) and ESL (electrical short-circuit) protection. In industrial applications, it can be used to eliminate any noise or overvoltage from power supply lines, and protect sensitive components from power supply spikes. Additionally, the SMDA15C-5.TBT can be used in telecommunications systems to provide ESD protection for receiver and transmitter circuits.

Working Principle

The SMDA15C-5.TBT is a Shottky-structure diode that works on the principle of avalanche breakdown. When the voltage across the diode exceeds a certain level, the diode will start to conduct. This is known as the avalanche breakdown voltage and is key to understanding the working of the diode. When an overvoltage event occurs, the voltage across the diode can reach this level, causing the current to start flowing. The SMDA15C-5.TBT is constructed to limit the current that can flow through the diode, and it is the maximum power dissipation rating of the diode that prevents it from being damaged by the high current.

Once the voltage across the diode reaches the clamping voltage, the current will start to decrease until the voltage reaches the clamping threshold voltage. The direction of the current is then reversed, and a reverse recovery time starts. During this time, the diode must be able to dissipate the energy from the overvoltage event quickly and safely, so that the device can return to normal operation. The SMDA15C-5.TBT is designed to have a fast recovery time, and can dissipate up to 1 watt of energy in the form of heat.

The SMDA15C-5.TBT is designed to provide high performance protection from ESD and other transient overvoltage events. The diode is constructed to limit the peak current to 15 A, with a clamping voltage of 7.5 V. This ensures that the device can provide the necessary protection to sensitive electronic components. The device also has a fast response time, allowing it to react quickly and safely in the event of an overvoltage event.
