Stresses exceeding "Maximum Ratings" may damage the device. "Maximum Ratings" are stress ratings only. Functional operation above the
recommended. Operating conditions is not implied. Extended exposure to stresses above the recommended operating conditions may affect device
reliability.
1. FR-5 = 1.0 x 0.75 x 0.62 in.
2. Only 1 diode under power. For all 5 diodes under power, PD will be 20%. Mounted on FR-4 board with min pad.
