*All tests are under pulse condition 200Hz, 10%D.C. with heatsink temperature 25℃. Mass production wafer level test condition could vary slightly. Operating current range is for reference at engineering stage in case the typical value is not ideal for module application. Within such a current range, an acceptable PCE can be maintained, though most parameters are subjected to change if operating current is different from the suggested typical value.
