30KPA258A

TVS-diodes are electronic components used to control and limit voltage. The 30KPA258A is a unidirectional Transient Voltage Suppressor (TVS) diode used in various applications for its protective and limiting properties. It specifically is designed to protect automotive circuits from voltage spikes or surges, and high-energy electrical transients.

30KPA258A Application Field

The 30KPA258A is applied in automotive applications where protection from overvoltage and transients are required. This includes fuel systems, airbag deployment systems, electrical distribution systems, ABS systems, and car audio systems. It is also used in other general-purpose applications such as LED lighting systems, telecommunications systems, and power switch circuits.

Working Principle of the 30KPA258A

The 30KPA258A is a unidirectional TVS diode used to protect automotive electronics from overvoltage and transients. The unidirectional feature is the primary feature since it limits voltage only in one direction, unlike bi-directional diodes, which limit voltage in both directions. The 30KPA258A features a peak pulse power of 30,000 watts and an operating temperature of -55°C to 150°C.

The 30KPA258A typically absorb high-energy narrow pulses and provide both protection and voltage-limiting action. This device is able to suppress transients up to 18V with a much lower clamping voltage than other similar TVS diodes. The 30KPA258A has a breakdown voltage of 13V, which results in a low on-state resistance and a fast response time. Furthermore, it features an extremely high surge capability which provides a higher level of protection against surges with an additional margin of safety.

Conclusion

The 30KPA258A is an ideal device for protecting automotive electrical components from overvoltage and transients, as well as general-purpose applications. It provides a high level of protection with its unidirectional property and has a breakdown voltage of 13V, resulting in a low on-state resistance and fast response time. This device is also able to absorb high-energy narrow pulses while providing both protection and voltage-limiting action. Furthermore, the 30KPA258A has an extremely high surge capability, providing a higher level of protection against surges with an additional margin of safety.
