Diode Arrays FAQ

What is the isolation voltage specification for the TO-220AB package?

The datasheet specifies an isolation voltage only for the ITO-220AB package, which is 1500 V AC. No isolation voltage rating is provided for the standard TO-220AB package.

How does the forward voltage drop vary with temperature?

The maximum instantaneous forward voltage decreases as temperature increases. It is rated at 0.82 V at 25 °C and drops to 0.73 V at 125 °C when tested at 30 A.

What is the maximum non-repetitive peak reverse energy rating?

The maximum non-repetitive peak reverse energy (ERSM) is rated at 25 mJ per diode, measured using an 8/20 μs waveform.
