NTE571 Description

Short technical summary and product information.

The NTE571 from NTE Electronics is a fast recovery avalanche rectifier diode designed for high voltage applications. Key electrical ratings include a maximum reverse voltage (Vr) of 1000V and an average rectified current (Io) of 2.9A. Its avalanche technology provides robust overvoltage protection and ruggedness in harsh environments.

 

Forward voltage is rated at a maximum of 1.78V when tested at 3A forward current. The reverse recovery time (trr) is 150ns maximum, classifying this diode as fast recovery (<500ns at >200mA), making it suitable for switching power supplies and pulse circuits. The operating temperature range spans from -65°C to 175°C, ensuring reliable performance across extreme conditions.

 

The device is housed in an Axial through-hole package, allowing for straightforward manual or automated insertion into circuit boards. Compliance data lists RoHS3, REACH unaffected, and MSL level 1 (unlimited), though these are unverified. The NTE571 is commonly used in high voltage rectification, freewheeling diodes, snubber circuits, and other power conversion stages.
