Soft Recovery Diode ADDM1494ND180 AS ENERGITM is a replacement, analogue, alternative and equivalent semiconductor device for soft recovery discrete diode M1494ND180 IXYS UK Westcode, Littelfuse.

Average forward current IFAV1494 ampere, repetitive peak reverse voltage VRRM1800V.

Soft Recovery Diodes are available with a range of reverse recovery characteristics tailored to meet the requirements of both freewheeling and snubber applications. These semiconductor devices are particularly suitable where soft recovery is required, such as RCD snubbers, voltage clamping and snubberless applications.

Features: class-leading performance and reliability; optimised for line frequency; low on-state losses; high reverse voltage and high current handling capabilities, high surge capability.

"Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series" for thyristors and diodes 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 10 to 15000 A, high resistance to thermal and electric cycling.

The technical specifications and parameters of M1494ND180 and replacement ADDM1494ND180, datasheet PDF, outline drawing and dimensions are listed below.

Our company provides a quality guarantee for soft recovery diodes of 2 years from the date of purchase. When supplying diodes, if necessary, we provide technical passport and certificate of conformity.

according to your requests and technical task.


Heat sinks for power rectifier disc diodes:

Heat sinks (radiators) are used for single- and double-sided cooling of power semiconductor devices in disc design.

Heat sinks of coolers are made of aluminum radiator profiles and do not require additional protective coating when used in various climatic conditions.

Air and water heat sinks for rectifier diode cooling are also available to order.

See for more information about heatsinks: "Air-cooled heatsinks O series for disc devices", "Air heatsink SF series", "Water heatsink SS series".
