5KP70A-G Circuit Protection

TVS (Transient Voltage Suppressor) Diodes are diodes that are designed to protect sensitive electronic equipment from power surges and voltage spikes. The 5KP70A-G is a general purpose Transil Surge Arrestor diode which offers effective protection from electrostatic discharges.

The 5KP70A-G consists of two-terminal avalanche diodes with fast and reliable switching characteristics. The 5KP70A-G comprises a pair of aligned back-to-back Zener diodes with reverse breakdown, which is also known as a bilateral Zener. This type of diode is designed to suppress high voltage transients caused by electrostatic discharges, lightning surges, and other powerline disturbances.

The 5KP70A-G offers protection for both AC and DC applications up to 70V. When the applied voltage exceeds the breakdown voltage, the diode will quickly clamp the voltage and shunt it to ground, limiting any surges above the breakdown voltage. In addition to the quick surge protection, the diode also features low clamping voltages, very low leakage currents and fast response times.

The 5KP70A-G is widely used in many applications such as consumer electronics, sensors and actuators, industrial, automotive, and medical devices. The device can provide efficient protection for both data lines and power lines. Its wide operating voltage makes it suitable for use in battery-operated equipment as well.

The working principle of the 5KP70A-G is simple yet effective. When the input voltage exceeds the breakdown voltage, the diode will quickly clamp the voltage and shunt it to ground. This limits any surges above the breakdown voltage, protecting the device from overvoltage transients. The device has multiple breakdown voltages, each designed to handle specific types of transients.

In conclusion, the 5KP70A-G is a general purpose Transil Surge Arrestor diode which offers effective protection from electrostatic discharges. It provides protection against high voltage transients in many applications such as consumer electronics, sensors and actuators, industrial, automotive, and medical devices. Its working principle is simple yet effective, providing fast protection against overvoltage surges.
