Package and board-fit for through-hole assembly
Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE300CAH is a through-hole part — hand-solderable and breadboard-friendly for prototyping, but equally at home in wave-soldered production runs. The DO-201 footprint is standard; the axial leads bend to fit 0.4-inch (10.16 mm) hole spacing on a perfboard or PCB.
Sourcing and lifecycle — active, no cross-reference on record
The 1.5KE series is a broad TVS family; if a direct replacement is needed, the base product number 1.5KE300 covers both unidirectional and bidirectional variants — confirm the polarity (bidirectional here) before substituting.
