Absolute Maximum Ratings (Note) (Unless otherwise specified, Ta = 25 ) Characteristics Symbol Rating Unit Forward current (DC) See Fig. 4.1. IF 180 mA Power dissipation PD 0.61 W Operating temperature Topr -40 to 120  Storage temperature Tstg -40 to 120 Junction temperature A (Note1) Tj 125 Junction temperature B (Note1) Tj 150 Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ("Handling Precautions"/"Derating Concept and Methods") and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Fig. 4.1 IF - Ta (Note 1), (Note 2) Note 1: The junction-to-ambient thermal resistance, Rth(j-a), should be kept below 70 /W so that this product is not exposed to a condition beyond the absolute maximum ratings. Junction temperature A: For general lighting applications, the current rating should be limited within the range shown by the dotted line (A) (Tj ≤ 125 ) and derated for temperature. Heat dissipation performance should also be considered when selecting a printed circuit board. Junction temperature B: The device temperature is between lines A and B shown in Figure 4.1 (125  < Tj ≤ 150 ). Because the device becomes so hot, it could be damaged in a short period of time. Therefore, in this temperature range, the device must not be used for any applications other than camera flashlights and similar applications (with a short lifetime on-time). Rth(j-a): Thermal resistance from the LED junction to ambient temperature Note 2: This LED has a relatively large (mid-range) operating power. When it is mounted in a narrow space or together with other components, they have mutual effects on their thermal characteristics; most notably, Rth(j-a) affects their junction temperatures. Therefore, care should be exercised to thermal management and PCB selection. If this LED operates at high temperatures, be sure to provide adequate heat dissipation by using an MCP, thermally enhanced PCB and the like, and perform thorough evaluation. 2 2014-06-19 Rev.1.0 TL1WK-WH1,L 5. Handling Precautions • This product is sensitive to electrostatic and care must be fully taken when handling products. Particularly in the case that an overvoltage shall be applied, the overflowed energy may cause damage to or possibly result in destruction of the product. Users shall take absolutely secure countermeasures against electrostatic and surge when handling the product. • A damage to the device might create a tiny leakage path, which causes the LED lamp not to light up in the low-current region or causes a drop in the VF rise voltage. Failure criterion: IF ≥ 0.5 mA @ VF = 2 V • If multiple LEDs are connected in parallel, they will experience variations in the forward current due to the characteristics differences in forward voltage. Ensure that the forward current of all the LEDs fall within the intended range of the system design, for example, by inserting current-limiting resistors to each LED string. Circuit Example • Since this product is intended to be used for display lighting, the measurement standard is based on the spectral sensitivity of the human eye. It is not intended to be used for any applications other than display lighting (e.g., sensors and light communications systems.) • Generally, GaN-based LEDs exhibit instability or significant device-to-device variations in the relative luminous flux in the low-current region. To avoid these problems, an application system should be designed in such a manner that the GaN-based LEDs are driven with a forward current of 2 mA or higher. • This device should not be reverse-biased. • When the device is used in places that are likely to be exposed to condensation, salt or corrosive gas, the effect on its performance and reliability must be thoroughly verified. • Please note the handling of products during evaluation. (1) Please do not handle apply pressure to the product with finger, tweezers, and others. Failure of product to light up may occur due to package deformation disconnection. (2) Please do not drop the product. There is a possibility for package transformation etc. .
