Absolute Maximum Ratings at Ta=25
| Parameters | Symbol | Rating | Units |
| Forward Current | IF | 350 | mA |
| PeakPulseCurrent (tp≤100μs, Duty cycle=0.25) | I pulse | 500 | mA |
| Reverse Voltage | VR | 5 | V |
| LED Junction Temperature | Tj | 125 | |
| Operating Temperature Range | Topr | -40 to +80 | |
| Storage Temperature Range | Tstg | -40 to +100 | |
