KD160KB80

Overview

The SanRex KD160KB80 is a silicon diode module featuring an isolated package with two cathode-common chips. It supports a repetitive peak reverse voltage of 800 V and a non-repetitive peak reverse voltage of 960 V. The average forward current rating is 160 A at a case temperature of 90°C, with an RMS forward current of 250 A under the same conditions. The surge forward current capacity is 3200 A for a half-cycle at 60 Hz. The maximum forward voltage drop is 1.35 V at 500 A instantaneous measurement. Operating junction temperature ranges from -40°C to +150°C, while storage temperature spans -40°C to +125°C. The isolation breakdown voltage is 2500 V RMS for one minute.
