DO-201AA axial — the through-hole survivor
The 1.5KE62-E3/73: Housed in a DO-201AA (DO-27) axial-lead package, this part is through-hole mounted — the leads carry the surge current into the die, and the body handles the thermal pulse. The operating junction temperature range spans -55°C to +175°C, so it can sit in an outdoor enclosure or near a hot power supply without derating at the upper end.
Obsolete — sourcing reality for the 1.5KE62-E3/73
Vishay has marked this part number as obsolete. No official successor or second-source cross-reference is recorded from the manufacturer. For a BOM that already carries this line item, the existing board layout and clamp voltage are locked; a replacement would require a pin-compatible TVS with the same 50.2 V standoff and 1500 W rating in a DO-201AA package.
