Under the test conditions of forward current IF = 700mA, ambient temperature Ta = 25°C, and relative humidity RH60%, this LED component presents the following electro-thermal performance parameters: The forward voltage (VF) ranges from a minimum of 1.2V to a maximum of 1.8V, with a tolerance of ±0.1V, ensuring stable voltage output during operation. The reverse current (IR) is controlled to a maximum of 10μA at a reverse voltage VR of 5V, effectively preventing reverse leakage. The typical viewing angle (2θ1/2), defined as the off-axis angle where luminous intensity reaches half of the peak intensity, is 30°, delivering focused light output. The junction-to-solder thermal resistance (Rth j-sp) is typically 7.5°C/W, enabling efficient heat dissipation and reliable long-term operation. Additionally, the component features an electrostatic discharge (ESD) withstand voltage of 2000V, providing robust protection against electrostatic damage in practical applications.
Under the standard test conditions of an ambient temperature (Ta) of 25°C and a relative humidity (RH) of 60%, the absolute maximum ratings for this LED component are defined as follows to ensure reliable and safe operation: The maximum continuous forward current (IF) is rated at 1000mA, while the maximum pulse forward current (IFP) reaches 1200mA, applicable only under the specified pulse conditions of a pulse width ≤100μs and a duty cycle ≤1/10. The maximum allowable power dissipation (PD) is 1.8W, and the reverse voltage (VR) is limited to a maximum of 5V to prevent reverse breakdown. The component is designed to operate within an operating temperature (Topr) range of -40°C to +85°C, with an identical storage temperature (Tstg) range for long-term storage. The maximum junction temperature (Tj) is specified at 115°C, which is critical for thermal management. It is important to note that exceeding any of these rated parameters may cause the LED's performance to deviate from the specified values, and strict attention must be paid to ensure power dissipation does not exceed the product's absolute maximum rating. All measurements were conducted in the standardized testing environment of Richled LED.
Under the standard test conditions of an ambient temperature (Ta) of 25°C, relative humidity (RH) of 60%, and forward current (IF) of 700mA, this LED component is categorized into three grading systems for precise performance matching. For radiometric power, the product is divided into three ranks: code PF0 offers a minimum of 600mW and a maximum of 650mW, code PF5 ranges from 650mW to 700mW, and code PG0 provides 700mW to 750mW of radiometric power. In terms of forward voltage grading, three ranks are available: code BA2 has a forward voltage range of 1.2V to 1.4V, code BA4 spans 1.4V to 1.6V, and code BA6 covers 1.6V to 1.8V, aligning with the component's forward voltage specifications. For peak wavelength, two ranks are defined: code 84F features a peak wavelength between 845nm and 850nm, while code 85E offers a peak wavelength range of 850nm to 855nm, ensuring consistent spectral performance for infrared applications. These binning codes enable customers to select components with tightly controlled optical and electrical characteristics tailored to their specific design requirements.
