Performance Graphs

The document includes several performance graphs illustrating:

• Fig. 1: Forward current versus voltage drop per diode: Shows the relationship between forward current (IF) and forward voltage drop (VF) for different junction temperatures (TvJ).
• Fig. 2: Surge overload current: Depicts the maximum surge overload current (IFSM) as a function of time (t) for various junction temperatures and conditions (e.g., 50 Hz, 60 Hz).
• Fig. 3: I²t versus time per diode: Illustrates the I²t value, used for fusing calculations, against time (t) for different junction temperatures and conditions.
• Fig. 4: Power dissipation vs. direct output current & ambient temperature: Shows total power dissipation (Ptot) as a function of average output current (IdAVM) and ambient temperature (TA), with curves for different thermal resistances (RthJA).
• Fig. 5: Max. forward current vs. case temperature: Displays the maximum average forward current (IF(AV)M) as a function of case temperature (TC) for various DC (duty cycle) values.
• Fig. 6: Transient thermal impedance junction to case: Plots the transient thermal impedance (ZthJC) against time (t) for the junction-to-case thermal path, with associated constants provided in a table.
