Transient Voltage Suppressors (TVSs) are a mature technology used to protect sensitive electronics from high voltage spikes. They are passive components that can be used to protect circuits from voltage transients such as ESD strikes, lightning strikes, and surges. They are typically connected across the terminals of a circuit, usually ground and power rails, and provide short-circuit protection in the event that the transient voltage rises above a given threshold.

The CR3602AA is a TVS diode designed to protect circuits from transient voltage spiking beyond 18 volts. It\'s a 3.4V, 6.1A discrete bidirectional diode, which means that it can dissipate voltage and current in both directions. The device is designed to handle up to 5.7A peak transient current (IPP) and up to 17A peak current during repetitive surge operations.

The CR3602AA is typically used in automotive, medical, telecom and industrial applications where voltage and current surges must be contained and dissipated. The diode can be used in applications like power supplies, protection circuits, IGBT modules, and LED lighting. Since it\'s a bidirectional diode, the CR3602AA can be used in applications that require reverse-polarity protection.

Working principle: The CR3602AA diode utilizes a voltage breakdown mechanism to dissipate the surges and relief the protected circuit from overvoltage. Transient voltage is clamped to its breakdown voltage (VBR) by allowing a certain amount of current to flow through it, then dissipated through its internal structure. When the voltage exceeds the breakdown voltage, it can conduct current between the anode and the cathode, but when the voltage is below the breakdown voltage, it can block the flow of current and isolate the anode and the cathode.

The CR3602AA is also equipped with a surge rating (IPP), which indicates the peak power it can handle in one-time surge application, and a repetitive surge rating (IAR) that indicates the peak power it can handle in repetitive surge application. It also features a Peak Pulse Power Dissipation (PpP) rating, which indicates the power the device is capable of dissipating in repetitive surge applications.

The CR3602AA is a reliable and cost-effective solution for transient voltage suppression in automotive, medical, telecom and industrial applications. It offers a low clamping voltage, high peak current capability, and excellent protection up to 18 volts. With its reverse polarity protection, it can be used to protect sensitive electronic components from overvoltage, ensuring their long term reliability.
