AEC-Q101 TVS for 12V/24V automotive bus clamping
The 1.5KE62HE3/54: The DO-201AA axial package handles the 1500W pulse without secondary heatsinking in typical PCB layouts.
Obsolete — sourcing through independent channels
Vishay lists the 1.5KE62HE3/54 as obsolete. The AEC-Q101 qualification and -55°C to 175°C operating range make this part suitable for existing automotive ECU designs that require a 1500W TVS in the DO-201AA footprint. For new designs, a current-production TVS from the same family should be evaluated.
Through-hole DO-201AA (DO-27) axial package. The 1.5KE body diameter and lead spacing match standard 0.100-inch pitch through-hole layouts. Tape-and-reel packaging is the original supply format; loose parts may be available from surplus stock.
