Single phase, half wave, 60Hz, resistive or inductive load.
For capacitive load, derate current by 20%.
Notes: 1. Valid provided that terminals are kept at ambient temperature.
2. Measured at 1.0MHz and applied reverse voltage of 4.0V DC.
3. Reverse Recovery Test Conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A. See figure 5.
