1500W bidirectional TVS — obsolete, sourced per RFQ
The 1.5KE6.8CHE3/54: It clamps transients at 10.8V maximum with a reverse standoff of 5.5V, protecting a single line from overvoltage in both polarities.
Clamping window and pulse current
Breakdown occurs at 6.12V minimum, with the device clamping at 10.8V max while conducting 139A peak pulse current. The 5.5V standoff means the line sees no leakage at the nominal operating voltage — the TVS stays transparent until a transient pushes above the breakdown threshold. Bidirectional construction means a single DO-201AA axial device protects against positive and negative surges — no need to series two unidirectional parts or worry about polarity orientation during assembly.
The TransZorb construction is a planar passivated silicon die in a glass-passivated axial package, designed for repetitive surge handling without degradation.
