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 4 diodes under power, PD will be 25%. Mounted on FR-4 board with min pad.
