TVS -Diodes

A transient voltage suppressor (TVS) is an electronic component that clips large voltage transients, particularly those in excess of the normal operating voltage range of a circuit or device, in order to protect it from damage. TVS diodes are a type of TVS that employ diodes as a voltage suppressing element in order to protect against damaging surges in a circuit.

One type of TVS diode is the 1.5KE300A-T, which is designed to protect against overvoltages with high surge capability, high power, and low reverse leakage. This type of diode features an excellent level of transient protection, lightning protection, and are designed to absorb a variety of transients including electrostatic discharges (ESD).

1.5KE300A-T Application Field and Working Principle

1.5KE300A-T TVS diodes can be applied in a wide range of environments and applications, including sensitive electronic equipment in military, industrial, medical, and power electronics. Their primary purpose is to protect circuits from overvoltage transients and surges, although they can also be used in place of a Zener diode to regulate voltage.

The 1.5KE300A-T diodes use a bidirectional, dual-MOSFET structure to quickly and reliably detect and clamp high-energy transient pulses. When the voltage applied to the diode exceeds the diode\'s breakdown voltage, the device effectively becomes a linear zener diode, allowing current to flow in both directions and clamping any sustained extra voltage. When the voltage drops back below the breakdown voltage, the device returns to its normal blocking state.

In addition, the 1.5KE300A-T is designed with an integrated protection circuit that protects against surge currents up to 1500W peak and 150W average, making it capable of offering maximum protection for a wide range of circuits and devices.

The 1.5KE300A-T is built with a compact package size of 5x5mm, making it ideal for a wide range of applications where space is a critical factor. Additionally, these diodes are RoHS compliant and possess UL flammability ratings of 94V-0, making them an environmentally friendly and durable option for many applications.

In summary, the 1.5KE300A-T TVS diodes are a reliable and durable option for robust protection against overvoltage transients and surges. With their high surge capability, low reverse leakage, and industry compliant package sizes and flammability ratings, these are an excellent choice for high-performance applications in military, industrial, medical, and power electronics.
