2.Initial Electrical / Optical Characteristics of High power 280nm UVC UV Light

Item	Symbol	Condition	Typ	Max	Unit
Forward voltage	VF	IF=350mA	5.2	-	V
Radiant flux	Φe	IF=350mA	55	-	mW
Peak Wavelength	λp	IF=350mA	280	-	nm
Spectrum half width	△λ	IF=350mA	10.0	-	nm
Thermal resistance	RθJS	-	8.4	9.9	℃/W
	RθJc_real	-	4.3	4.6
	RθJc_el	-	4.1	4.4

* Characteristics at Ts=25℃.

* Radiant flux value as per CIE 127:2007 standard.

* RθJS is the thermal resistance from the junction to the Ts measurement point.

* Thermal Resistance values (RθJc_real) determined by considering the energy conversion efficiency (ηe=3%). Refer to JESD51.

* The thermal resistance between value (RθJc) is used to perform logical analysis (e.g. computer-based thermal analysis simulation) and represents a thermal resistance between the die to the Tc measurement point (PCB used : Aluminum PCB t = 1.5mm, Insulating layer t =0.12mm).

* For more details on thermal resistance, see CAUTIONS, (6) thermal management.

* It is recommended to operate the LEDs at a current greater than 10% of the sorting current to stabilize the LED characteristics.
