SMA5J20AHE3/5A devices are a small and cost effective TVS (transient voltage suppressor) diode, designed to protect sensitive electronic components from voltage spikes. The device features two diodes in one package, with a stand-off voltage rating of 5.6 to 20V.

As a transient voltage surge suppressor diode, SMA5J20AHE3/5A devices are equipped with two tiny chips in a single SMA package. The device has an operating voltage of 5.6V, and is designed to provide protection from transient voltage spikes in 5V, 12V and 24V systems. The chip also has a breakdown voltage rating of 20V, which allows for protection against higher voltage surges.

The SMA5J20AHE3/5A device’s working principle is based on a principle of reverse biasing. The diode consists of two diodes, in opposite polarities. When a voltage surge occurs, the diode will produce a high resistance path for the current to flow in the reverse direction. The high resistance path will reduce the voltage and absorb the energy from the surge.

The SMA5J20AHE3/5A device is suitable for a range of applications. It is especially useful in automotive, medical equipment, computers and communications. The device offers protection from surges from 10V to 20V, with a breakdown voltage of 5.6V, making it ideal for 12V and 24V systems. Additionally, the device is approved by the AEC-Q101 and RoHS standards.

The SMA5J20AHE3/5A device is available in a range of different packages, allowing for its use in a variety of applications. The device is available in both SMT (surface mount technology) and leaded packages, allowing for quick and easy integration into circuit boards.

Overall, SMA5J20AHE3/5A devices are a small and cost effective transient voltage surge suppressor diode, offering protection from voltage spikes in 5V, 12V and 24V systems. The device offers reverse biasing protection, with a breakdown voltage of 5.6V and a stand-off voltage rating of 5.6 to 20V. The device is available in both SMT and leaded packages, and is approved by the AEC-Q101 and RoHS standards.
