Typical DC Forward Current vs. Forward Voltage

The graphs below predict the change in forward voltage compared to the value at case temperature of 25°C at 1000 mA under various use

conditions. These graphs can be used to determine the effects of case temperature and forward current on the values of minimum, typical and

maximum forward voltage to define performance at the expected use condition.

Typical DC Forward Current vs. Forward Voltage 1x4 Configuration

Typical DC Forward Current vs. Forward Voltage 1x2 Configuration

Notes for Figures 5 and 6:

1. All values compared to reference value at case temperature of 25°C and 1000 mA DC forward current.
