This LED component exhibits stable electrical and thermal performance under the test conditions of IF = 350mA, Ta = 25°C, and RH60%. Specifically, both the white (W) and blue (B) channels feature a forward voltage (VF) ranging from 2.8V to 3.2V with a tolerance of ±0.1V. The reverse current (IR) is limited to a maximum of 10µA when tested at VR=5V, ensuring reliable anti-leakage performance. Optically, it offers a wide typical view angle (2θ1/2) of 120°, facilitating uniform light distribution. Thermally, it demonstrates a low typical thermal resistance (Rth j-sp) of 7.5°C/W, enabling efficient heat dissipation from the junction to the solder point. Additionally, it complies with an electrostatic discharge (ESD) withstand voltage of 2000V, safeguarding against potential damage during manufacturing and handling processes.
Table 4 presents the Absolute Maximum Ratings of the LED product measured under the standardized environment of Richled LED at Ta = 25°C and RH60%. For Forward Current B (IF), the maximum rated value is 500 mA, while the Pulse Forward Current B (IFP) allows a peak of 600 mA. In contrast, Forward Current W (IF) has a higher absolute maximum rating of 700 mA, with its corresponding Pulse Forward Current W (IFP) supporting up to 800 mA, where the IFP condition is specified with a pulse width of ≤100 μs and a duty cycle ≤1/10. In terms of power dissipation, Power Dissipation B (PD) is rated at 1.6 W, and Power Dissipation W (PD) can reach up to 2.24 W. The Reverse Voltage (VR) that the device can withstand is 5 V. Regarding temperature ratings, the Operating Temperature (Topr) and Storage Temperature (Tstg) both range from -40°C to +85°C, and the Junction Temperature (Tj) has an absolute maximum limit of 150°C. It is important to note that the LED’s properties may deviate from the values provided in this table if the operating conditions exceed the specified parameter range, and strict attention must be paid to ensure that power dissipation does not surpass the product’s absolute maximum rating to maintain proper operation and product integrity.
