Pavlo GorkunSingle Diode Module ND171N18K (170A 1800V) Infineon Replacement
Single Rectifier Diode Module AMND171N18K AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for normal recovery diode ND171N18K Infineon Technologies. Average forward current IFAV – 170 ampere, repetitive peak reverse voltage VRRM – 1800V.
Features of Standard Rectifier Diodes: optimised for line frequency; low on-state losses; high reverse voltage and high current handling capabilities; press pack standard ceramic housing; designed for high power industrial and power transmission applications. Their main applications are rectifiers for large AC drives, aluminum smelting and other metal refining as well as trackside supply. Air and water heat sinks for diode cooling are also available to order.
Rectifier Diodes AS ENERGITM have the following features: industry standard housing; low static and dynamic losses, high values of VRRM/VRSM, extensive experience of using the devices in various industries, range of voltages from 100 to 9000 V and amperages from 100 to 7500 A, high resistance to thermal and electric cycling.
The technical specifications and parameters of ND171N18K and replacement AMND171N18K, datasheet PDF, outline drawing and dimensions are listed below.
Our company provides a quality guarantee for single diode modules of 2 years from the date of purchase. When supplying diode modules, if necessary, we provide technical passport and certificate of conformity.
The final price for single diode modules depends on the class, quantity, delivery terms, manufacturer, country of origin and form of payment.
