The 1.5KE62CHE3/54: For a BOM line that still calls out this specific order code, the supply path runs through independent distribution — surplus or new-old-stock inventory, confirmed at RFQ. No direct factory or franchised channel supports new orders.
1500 W peak pulse — what the rating governs
The 50.2 V reverse standoff means it sits across a 48 V nominal rail without conducting in standby. Breakdown occurs between 55.8 V and the clamp voltage — the avalanche region absorbs the transient energy. This is a unidirectional device? No — the part is a single bidirectional channel, clamping both polarities in one package.
Automotive-grade TransZorb — AEC-Q101 pedigree
The qualification covers reliability stress and PPAP documentation for automotive OEMs. The DO-201AA (DO-27) axial leaded package suits through-hole mounting on power entry boards, battery junction boxes, or ECU input protection stages where a surface-mount TVS might not handle the pulse energy or thermal cycling.
