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 | ℃ |
| Soldering Time at 260 ℃ (Max.) | Tsol | 5 | Seconds |
Notes:
1. Proper current derating must be observed to maintain junction temperature below the maximum.
2. LEDs are not designed to be driven in reserve bias.
