The SM6T200CAHE3/5B is a part of TRIPLE SURGE PROTECTION thyristors series from Littelfuse, which are included in the TVS - Diodes category. It is a smart Unidirectional 6.0kW, TVS device with 1500W for each peak current. It is designed to protect equipment and components from overcharging and excessive voltage during a power surge.

The SM6T200CAHE3/5B is a low-power surge protector, which can protect small to medium electronic components from voltage transients. It can protect components from high-voltage surges, especially during brown outs or other power abnormalities. The SM6T200CAHE3/5B is a three-terminal device composed of two PN junctions connected in back-to-back configuration. It can dissipate an energy range of 6kW up to a peak current of 1.5kA.

This device is designed to be used in a variety of applications, including IT, consumer, home appliance, industrial, and automotive. It provides robust protection against lightning transients, overvoltage, and overcurrent with its excellent peak current handling and low-leakage current design. It is available in a variety of packages, such as SMC, SMD, DIP, and SOT23.

The SM6T200CAHE3/5B is composed of a metal-oxide varistor and an avalanche diode. The metal-oxide varistor acts as a clamping element to absorb the energy from a transient by clamping it to a specific voltage. The avalanche diode, on the other hand, functions as a crowbar to dissipate any excess energy from the varistor and prevent it from creating a destructive path for current. The Avalanche diode is triggered when the clamping voltage setpoint is exceeded.

The SM6T200CAHE3/5B device also has a positive temperature coefficient (PTC) device which limits the surge current that flows through the device, and allows only the necessary current to the load. This helps to protect the other components from damage due to excessive current. The device also has a fast-acting zener diode that provides protection against overvoltage surges.

In short, the SM6T200CAHE3/5B is an ideal choice for surge protection. Its low-leakage design, excellent peak current handling, and wide voltage range make it a perfect fit for protecting both consumer devices and industrial applications from performance-degrading transients. By using this device, designers are assured that their equipment and components will be protected from overcharging and overvoltage.
