† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: These values apply for tw ≤ 100 µs, duty cycle ≤ 20%.

NOTE 3: Ix is measured under the following conditions with one diode static, all others switching:

Switching diodes: tw = 100 µs, duty cycle = 20%

Static diode: VR = 5 V

The static diode input current is the internal crosstalk current Ix.
