Product details

TransZorb bidirectional TVS — 1500 W peak pulse, 66.4 V standoff

The 1.5KE82C-E3/54: Its 66.4 V reverse standoff voltage and 73.8 V minimum breakdown voltage protect 48–60 V rails from transients, clamping at 118 V maximum at the 12.7 A peak pulse current.

Peak power and clamping — what 1500 W means for rail protection

For a 66.4 V standoff rail, the clamping voltage of 118 V at 12.7 A means the TVS limits the surge to a level that downstream semiconductors rated for 120 V or higher can survive. The bidirectional configuration protects both polarities with a single device, useful on AC-coupled or floating signal lines.

Obsolete — sourcing through independent channels

Vishay lists the 1.5KE82C-/54 as Obsolete.
