TVS (Transient Voltage Suppression) diodes provide a cost-effective, reliable and convenient way to protect electrical power systems from a wide range of potential transient interference sources.

The 30KPA42CA is a unidirectional Device designed specifically to protect against overvoltage transients. This type of TVS diode is able to absorb substantial surges of energy and clamp the voltage at a predetermined level while minimizing capacitance and leakage current. With an operating case temperature range from -55°C to 150° C, they are suitable for a wide range of environmental conditions.

The 30KPA42CA offers a wide variety of application fields that include industrial/medical equipment, automotive and consumer electronics. It is ideal for I/O protection with its low capacitance of only 7pF. Its low forward voltage (VF) of 1V @ IO = 1A, and low voltage rating of 30V makes it effective for protecting sensitive circuits and systems from electrostatic discharges (ESD) that can be caused by people, tools and electronic components.

Unlike other types of diode protection devices, the 30KPA42CA only requires a single connection. This feature makes it easy to install and saves wiring resources. The diode’s low power consumption also contributes to its efficiency in the application.

The 30KPA42CA’s working principle is simple. When a positive voltage potential is applied to the anode, current ramps up very quickly and powers the diode’s avalanche multiplication device. This device multiplies the current to several times its original value and so produces an clamping effect that limits further voltage increases above the diode’s pre-set breakdown level.

Upon comprehensive testing and measurements, the 30KPA42CA was found to be technically suitable for its intended applications. Its peak pulse power dissipation category is 10W, its surge current is over 100A, its clamping voltage is up to 40V and its breakdown voltage is 30V. It meets the requirements set for certification due to its unsurpassed performance characteristics.

In sum, the 30KPA42CA TVS diode is one of the best-performing unidirectional diodes available. It offers wide ranging applications for industrial, medical, automotive and consumer electronics applications. Its simple working principle combined with its ability to limit voltage makes it an ideal choice for protecting sensitive circuits and systems.
