Introduction of TVS - Diodes

Transient Voltage Suppressor (TVS) diodes are a type of overvoltage protection devices which has become a popular choice for protecting various type of electrical and electronic equipment from voltage transients. The TVS diode series are designed to protect components from high energy voltage transients to prevent damages caused by lighting or other electrical storms. The diodes also help protect electronic systems from low energy or repetitive transients due to equipment or wiring faults.

15KPA18A-B Application Field and Working Principle

The 15KPA18A-B TVS diode is used primarily in automotive applications for protection against power transients, electromagnetic pulses (EMP), electromagnetic interference (EMI) and electrical overstress (EOS). It is also suitable for applications in industries, power systems, military and aerospace, consumer electronics, computing and communication equipment.

The TVS diode series 15KPA18A-B is designed for clamping transients with high surge current capability. The 15KPA18A-B has a reponse time of less than 1.0 ns for negative transients and is rated for operation in temperatures between -65°C to +150°C. It has an excellent clamping ratio at a variety of applied transients and provides low power loss and low leakage current. The 15KPA18A-B has a clamping voltage of 18V.

The TVS diode series 15KPA18A-B works by clamping the overvoltage transient current response to a safe clamping voltage. When the voltage on the TVS diode is greater than its clamping voltage, it starts to conduct current. The current then flows to ground and the voltage is clamped to a safe level. The current then returns to a safe level once the voltage is clamped to the safe clamping voltage. This process helps to protect more vulnerable components from damaging current pulse.

The TVS diode series 15KPA18A-B is available in different packages such as SMA, SMB, SMC, SOD-323 and SOD-123 that are suitable for board-level applications. These packages have a low profile design, high withstand voltage, low capacitance and increased system reliability.

The 15KPA18A-B TVS diode series is a great solution for surge protection applications which require minimal leakage current, fast response and high surge capability. It provides protection from EOS, EMI, and EMP as well as overvoltages. It is easy to use and cost-effective. In addition, it can help extend the life of equipment by preventing the damage caused by voltage transients.
