TVS - Diodes, often referred to as Transient Voltage Suppressors (TVSs), are active components used to protect electronic components, devices, and systems from overvoltage, overcurrent, and electrostatic discharge (ESD). The 1.5CE33A TR is a 300W TVS - Diode from Littelfuse, and it is part of the TVS400JRAJKE product family.

The 1.5CE33A TR is designed for use in power systems, including solar inverters, motor drives and controllers, rectifiers, and AC/DC power supplies. It offers protection from overvoltages, overcurrents, and ESD events. The device is capable of withstand ratings of up to 300W, and it has a surge clamp voltage of 7.2V. It also features an operating temperature range of -55°C to +175°C, and its maximum power dissipation is 33 W.

The 1.5CE33A TR has a working principle that is based on a reverse-blocking thyristor. When an overvoltage event occurs, the device clamps the voltage across the input and output, which reduces the transients and protects the connected components from damage. When the voltage across the device falls below a certain level, the device is turned off and is considered to be in the reverse blocking state. This prevents any current flow from the output to the input and effectively isolates the protected components.

In addition to its ESD protection capabilities, the 1.5CE33A TR also features Electro-Magnetic Interference (EMI) filtering capability. It has a very low capacitance (16.6pF typical), which allows it to reduce common mode noise pulses. It can be used in various applications as a low-capacitance EMI filter, including in automotive, telecom, medical, and industrial systems.

The 1.5CE33A TR also features fast response time, low leakage current, and robust tolerance to voltage spikes, making it ideal for use in harsh environments. It is designed with a lower capacitance than traditional transient voltage suppressors, making it easier to integrate into existing designs. Additionally, the device also features a low on-state resistance, ensuring low power losses, and increasing efficiency.

The 1.5CE33A TR is a versatile device that can be used in a wide variety of applications. It is an ideal solution for protecting electronic components, devices, and systems from overvoltages, overcurrents, and ESD events. It can also be used as an EMI filter, allowing users to reduce common mode noise pulses. Additionally, its fast response time, low leakage current, and robust tolerance to voltage spikes make it ideal for use in harsh environments.
