P4KE550C-G Circuit Protection

The P4KE550C-G is a part of the Littelfuse’s Transient Voltage Suppressors (TVS) family of devices, specifically within the TVS diodes category. Designed to meet the latest industry standards, the P4KE550C-G is engineered to protect sensitive electronics from electro-static discharges (ESD), surges and lightning by clamping the voltage to a safe level.

The P4KE550C-G is a bi-directional TVS diode, meaning it can uniformly protect against damaging voltage transients regardless of when the surge enters the electrical system. Other features include a broad working temperature range of -55°C to 125°C, ultra-low capacitance and reaction time of less than one nanosecond. It is suitable for use in a range of commercial and industrial applications.

The P4KE550C-G with its unidirectional clamping and low clamping voltage offers a cost effective alternative to other types of over-voltage protection devices. Low clamping voltage, along with surge capabilities of up to 400 Watts, makes the P4KE550C-G an ideal choice for applications such as high-current LEDs and DC-DC converters. The P4KE550C-G also combines the necessary over-voltage and surge protection in one compact package.

The P4KE550C-G’s functionality depends on the characteristics of its diode construction. When a reverse voltage is applied, the diode is forward biased and begins to conduct current when an ESD, surge or surge impulse event occurs, the diode starts to conduct and clamps the voltage to a safe level.

The P4KE550C-G is available in a variety of packages which makes it suitable for a range of commercial and industrial applications. It is interchangeable with other TVS diodes and compatible with standard mounting methods. Its ESDA2 and IEC 61000-4-2 certifications makes it a suitable choice for applications requiring reliable surge protection.

In summary, the P4KE550C-G from Littelfuse is an effective and cost-efficient bi-directional TVS diode. With its fast response time, low turn-on and clamping voltages and broad operating temperature range, the P4KE550C-G is suitable for high-current LED, DC-DC converter and other commercial and industrial applications requiring reliable surge protection.
