NTE5181A Description

Short technical summary and product information.

The NTE5181A is a high-power Zener diode from NTE Electronics, providing a nominal Zener voltage of 6.8V with a tolerance of ±5%. It is designed for voltage regulation and overvoltage protection applications requiring up to 10W of power dissipation.

 

With a maximum impedance (Zzt) of 1.2 ohms, this diode offers stable voltage clamping under load. It operates over a wide temperature range from -65°C to 175°C, making it suitable for harsh environments.

 

The device is housed in a DO-203AA / DO-4 stud mount package, which allows for chassis mounting and efficient heat sinking.
