The 1N6281A-E3/51 is part of a range of voltage-supplied Transient Voltage Suppressors (TVSs). It refers to a general class of products used to protect electronic components and equipment from power related problems and disruptions, such as voltage spiking, over-voltage, and Electrostatic Discharge (ESD) threats. The 1N6281A-E3/51 provides a highly effective solution for protecting device (DUTs) operation in the following 3V to 9V application fields.

Applications

The 1N6281A-E3/51 is capable of protecting products in a range of 3V to 9V application fields. Its main features make it an ideal choice for a variety of applications, such as:

• Power Supplies
• Computer Systems
• Data Acquisition Equipment
• Telecommunications
• Portable Electronics
• Networking

Its robust housing makes it suitable for use in any environment, including small and enclosed spaces.

Working Principle

The 1N6281A-E3/51 is a bidirectional voltage-supplied device with a Gate oxide protection layer built between the anode and the cathode. The primary purpose of the Gate oxide layer is to form a barrier to prevent flow-back current and improve ESD performance (up to 8kV contact using the Human Body Model).

When a surge of voltage is seen on either the anode or the cathode, a current is discharged from the Gate oxide layer to protect the device and the surrounding electronics from damage. The current is then transferred quickly to the anode and the cathode in order to clamp down the offending voltage.

The 1N6281A-E3/51 is also equipped with over-voltage protection, providing additional protection for when the voltage level rises beyond the normal operating range. When this happens, it will automatically reduce the voltage level to ensure the safe operation of the device and the surrounding electronics.

Conclusion

The 1N6281A-E3/51 is a highly effective transient voltage suppressor capable of protecting devices in a range of 3V to 9V application fields. Its integrated Gate oxide layer, over-voltage protection, and robust housing make it an ideal choice for a variety of applications, such as power supplies, computer systems, data acquisition equipment, telecommunications, portable electronics, and networking.
