ERZ-SF2MK270

The ERZ-SF2MK270 is a two-terminal device that provides voltage and transient protection for critical circuits typically found in consumer electronics and computer-related applications. This device is classified as a TVS (Transient Voltage Suppressor) – Varistor – MOV (Metal Oxide Varistor), and has two distinct sections: the varistor and the MOV kick-back element. Both sections are designed to provide unidirectional protection capability, which helps provide quick suppression of transient voltage, while still achieving an acceptable clamping voltage.

ERZ-SF2MK270 Applications

The ERZ-SF2MK270 is designed for a wide range of consumer electronics and computer-related applications. It is recommended for use in applications such as: AC/DC power supplies, ATX motherboards, communication systems, set-top boxes, automotive electronics, and consumer electronics, among others. The ERZ-SF2MK270 is specifically suitable for line-to-ground protection from ESD and overvoltage due to lightning surges. The device also offers very fast response times in order to protect circuits against high-energy spikes, as well as continuous overvoltage conditions.

ERZ-SF2MK270 Working Principle

The working principle of the ERZ-SF2MK270 is both simple and highly effective. This device is composed of two distinct sections: the varistor and the MOV kick-back element. The varistor is one of the most commonly used protection devices due to its simple design and increasingly better performance characteristics. It works by creating an environment where an increase in voltage causes an immediate decrease in current. This in turn creates a clamping action which reduces the peak voltage of a transient surge. Each varistor has a blocking capability, meaning it can block static voltage. The MOV kick-back element works in combination with the varistor and provides superior, lightning-fast response times, while still achieving an acceptable clamping voltage.

The two sections of the ERZ-SF2MK270 are designed to work in unison. When a static voltage condition is present, neither section is activated. However, when there is a surge or a transient event, the MOV kick-back element kicks in and acts quickly, clamping the voltage at an acceptable level. At the same time, the varistor component helps reduce the voltage to a safer level, while still allowing the current to flow.

Conclusion

The ERZ-SF2MK270 is designed specifically for use in consumer electronics and computer related applications. This device provides reliable protection against transient voltage events, and utilizes two distinct sections, the varistor and the MOV kick-back element, which work together to provide a quick response time and reliable clamping voltage. Overall, the ERZ-SF2MK270 is an effective and reliable two-terminal device that provides superior protection against transient voltage events.
