Device identity and key parametrics
The Comchip Technology 1.5KE43A-G is a Zener-type transient voltage suppression (TVS) diode in a DO-201AA / DO-27 axial-lead through-hole package. It is a unidirectional device, with one suppression channel per package.
Operating range and deployment context
Mounted through-hole in the DO-201 footprint, the axial leads handle repeated surge current without lifting a pad — a consideration for boards that see field return vibration or thermal cycling.
Lifecycle and supply posture
Comchip Technology lists the 1.5KE43A-G as Active in production. The part is sourced to order against BOM quantities through independent distribution channels.
