Automotive-grade TVS in a through-hole axial package
The 1.5KE13AHE3_A/D: It is a unidirectional Zener-type suppressor in a DO-201AA (DO-27) axial-lead through-hole package.
Package and board integration
The DO-201AA axial package (also known as DO-27) is a through-hole form factor with a 0.052-inch diameter lead. It requires a 0.040-inch (1.0 mm) hole in the PCB and is typically hand-soldered or wave-soldered. The body length is about 7.6 mm with a 5.3 mm diameter. The part is supplied in Tape & Box (TB) packaging — not tape-and-reel — so it is suited for hand-insertion or low-volume assembly rather than automated pick-and-place.
