Diodes

You might be asking yourself if you need to use Diodes in circuit protection kits. You do, and that's the right choice. These devices are used in numerous applications and are classified according to their characteristics, specifications, and applications. Listed below are some of the applications of Diodes in circuit protection kits. They're an essential part of any circuit protection kit. Diodes have multiple uses, including demodulators in radio receivers and rectifiers in computers.

AVALANCHE DIODES:

These are typically used as a safety device in other semiconductor devices. Their large p-n junctions enable them to conduct high currents to the ground without damaging themselves. Despite their low resistance, they have a negative resistance caused by quantum tunneling, allowing them to be used in simple bistable circuits and signal amplification. In addition, Tunnel Diodes can withstand high magnetic fields, making them a valuable component in circuit protection kits.

Thyristors

Thyristors in Circuit Protection Kits are excellent components for telecommunications equipment protection. They feature bidirectional crowbar protection and voltage ranges of 62 to 320 V. They have a low on-state resistance of approximately 12 pF at 50 V, making them excellent choices for low-voltage applications. Thyristors are often used as crowbar devices to prevent overvoltage from damaging electronic equipment, such as computer circuits.

A thyristor is a four-layer solid-state semiconductor device with three p-n junctions, known as a gate. It conducts when it receives a triggering current or the voltage across the device is forward biased. This property causes the thyristor to behave as a bistable switch. A three-lead thyristor has three terminals, referred to as a control lead.

Thermal Switches

Thermal switches are a common type of circuit protection kit. These thermally actuated electromechanical on/off switches operate under conditions of thermal expansion and contraction. They can be re-used for temporary protection and are user correctable. A thermal switch will change state when a temperature differential between its two terminals rises above or below a setpoint temperature. The switch's state is usually temporary and may produce a slightly audible signal.

Another common type of circuit protection kit includes thermal cutoffs. These devices rely on external input and often contain a one-time fusible link. They will fail to protect a circuit if the ambient temperature is higher than the melting point of the link. Thermal cutoffs, also known as thermal switches, are like reed switches and resettable fuses. Both thermal switches and thermal fuses restrict current flow when their ambient temperature reaches a specified temperature. Once the conductor temperature drops below that temperature, thermal cutoffs and thermal fuses will resume normal operation.

Thermal Cutoffs

Thermal cutoffs are devices that are used to prevent a certain product's temperature from rising above a threshold. When a product experiences a fault, the cutoff opens when the temperature exceeds a predetermined level. When the product reaches a safe temperature, the cutoff closes and the circuit reverts to its normal operating temperature. Thermal cutoffs come in various sizes and levels of protection, ranging from small appliances to larger ones. They also protect battery packs and electric motors.

Thermal fuses are another type of circuit protection kit. These devices are designed to cut off power to heating elements when they fail. When thermostats malfunction, thermal fuses disconnect the current from the heating element, which may result in dangerous temperatures and fires. It is important to choose thermal fuses carefully and choose the correct one for your project. If you are unsure about which type of thermal fuse is right for your needs, read this guide.

TVS Diodes

Circuit protection kits that include TVS diodes should meet the same requirements as those in the market. These devices should not only protect from transient events but also ensure the signal integrity of the communication packet. For this purpose, they should have a low capacitance. TVS diodes should be selected in line with the rated transient pulse power of the circuit. They should not be used in circuits that have a very high surge power or a high transient pulse.

High-power TVS diodes from Eaton have been rated for 5000 watts peak power. They reduce board space and protect against high power surge events and ESD. High-power TVS diodes provide additional protection for network ports, such as the Type-A and Type-B Gigabit Ethernet. These high-power diodes are also useful for protecting DC power supplies and signal lines.
