TV15C300J-G Circuit Protection

TVS diodes protect sensitive circuits against damaging overvoltages, providing short circuit protection for equipment. TV15C300J-G application field and working principle is related to this kind of protection.

The TV15C300J-G is primarily used in Automotive systems as a 15kW (30A) unidirectional device. This product is designed to protect devices such as relays, sensors, injectors, and other automotive components from voltage transients and other failure mechanisms. It is intended for use in oscillator and logic circuits, and offers a familiar package size of 1.6mm x 0.8mm, making it ideal for end products requiring miniaturization.

The TV15C300J-G uses a proprietary dynamic clamping structure that can absorb large transient voltages and will not create a ground bounce. The device is qualified per AEC-Q101 and offers near zero power consumption with an effective clamping voltage of 30V. It is RoHS compliant and also provides overvoltage protection up to 65V.

The TV15C300J-G’s working principle is based on the avalanche breakdown of the diode when the applied voltage or current exceeds its avalanche voltage, breakdown current, or peak current ratings. When the applied voltage or current is greater than the avalanche voltage, breakdown current, or peak current rating, the diode absorbs the excess energy and reduces the voltage or current to a safe value. The same principle applies for the TV15C300J-G’s bidirectional protection.

The TV15C300J-G also offers high capacitance, enabling it to absorb the transient energy quickly and efficiently. This helps to protect the active components from damage due to transient overvoltages and sudden surges in current. The device is designed to operate with very low power consumption and is available in both surface mount and leaded packages.

In conclusion, the TV15C300J-G is an excellent device for protection of sensitive circuits against damaging overvoltages. Its dynamic clamping structure absorbs large transient voltages and will not generate a ground bounce. It is qualified per AEC-Q101, RoHS compliant, and can also provide overvoltage protection up to 65V. It is an ideal choice for end products that require both miniaturization and effective protection from overvoltages.
