Note 5: VISO, VIOTM, VIOSM, VIOWM, and VIORM are defined by the IEC 60747-5-5 standard.

Note 6: Product is qualified at VISO for 60s and 100% production tested at 120% of VISO for 1s.

Note 7: Devices are immersed in oil during surge characterization.

Note 8: Capacitance is measured with all pins on field-side and logic-side tied together.
