Notes:
• UL Recognized component, UL File E153537.
• Line to Line voltage is approximately 1.8 to 2 times the stated Line to Ground voltage.
• The rated discharge current is the total current equally divided between each line to ground.
• Surface Mount (SM) parts may show a temporary increase in DCBD after the solder reflow process. Most devices will recover
within 24 hours time. It should be noted that there is no quality defect nor change in protection levels during the temporary change
in DCBD.
• At delivery AQL 0.65 AQL Level II, DIN ISO 2859
• Bourns recommends reflowing surface mount devices per IPCVJEDEC J-STD-020 rev D.
