20 A maximum forward DC current and < 2 V voltage drop were measured at fixed case temperatures in the range from 0 °C to 200 °C using an active heat sink.
At low forward voltage, the current increases exponentially.
The forward voltage is defined as a positive bias voltage applied on the top In electrode.
The maximum forward acceleration declines slowly with speed.
Forward current is measured through the shunt resistor and forward voltage— is measured at the transistor terminals.
In addition, the forward voltage was reduced from 3.69 V to 3.42 V at 20 mA.
The best PVSC achieves a PCE of 20.10 19.855)% measured under reverse (forward) voltage scan.
Each LED string may have a different forward voltage and current setting.
More specifically, the influence of the N+ floating emitter on the forward voltage drop and forward-biased safe operating area (FBSOA) is studied in detail.
For example, low forward voltages, high light output powers at 20 mA, low reverse currents, long term stability and high electrostatic discharge robustness have to be guaranteed in a temperature range of −55 +85°C and at a maximum humidity of 85%.
