The P4SMA400AHE3_A/H is a transient voltage suppression (TVS) diode designed to protect sensitive electronic devices from the potentially damaging effects of electrical spikes, surges, and transients. Its common applications include the protection of data communications ports, telecommunications equipment, AC power supplies, and other critical components that could be vulnerable to damage from electrical transients.

The P4SMA400AHE3_A/H is a double transient voltage suppressor (TVS) device specifically designed to eliminate the surge and transient noise that a typical diode on an AC power line will not suppress. It offers superior clamping capability over single TVS diodes, and its very low capacitance provides an excellent broadband frequency response. The P4SMA400AHE3_A/H is also capable of handling large transients at both the peak and the corresponding low points in the AC power line.

The P4SMA400AHE3_A/H utilizes a p-type MOSFET and a second n-type MOSFET to form a five-layer diode structure. This multi-layer design allows the device to rapidly respond to voltage changes, quickly and effectively clamping any transients to a safe operating level. In order to ensure optimal performance, the device has a low clamping voltage of less than 5V with an effective clamping voltage range of 5V to 370V. Additionally, as the device is made from two MOSFETs, the response time is stable, regardless of current or temperature changes.

The P4SMA400AHE3_A/H is also designed to protect against reverse bias leakage and voltage transients, as well as providing a robust thermal protection system. In order to achieve this, the device is designed with an internal resistance and leakage current limit, enabling the device to maintain a consistent operating temperature. Additionally, the device has an over-temperature shutdown feature that will automatically shut down the device in case of excessive temperatures.

The wide operating temperature range (0 to + 70°C) and small form factor of the P4SMA400AHE3_A/H make it a suitable choice for protecting a variety of commercial, medical, and industrial applications. The device is also capable of handling high peak currents, making it well suited for wireless communication components, such as Wi-Fi and Bluetooth, as well as for digital media applications.

In conclusion, the P4SMA400AHE3_A/H is an outstanding transient voltage suppressor (TVS) diode designed to protect electronic devices against electrical transients, over-voltage conditions, and reverse-bias leakage. It is able to handle large transients, provide an excellent broadband frequency response, and maintain consistent operating temperatures. Furthermore, the device is also highly durable and provides a wide operating temperature range making it suitable for a wide range of commercial, medical, and industrial applications.
