Product details

The 1.5SMC16AT3G: The DO-214AB (SMC) package is a surface-mount footprint common in power-supply input stages, telecom line cards, and industrial control boards where a single TVS absorbs a defined surge without sacrificing board space.

Lifecycle reality — obsolete, no direct successor

Littelfuse has marked the 1.5SMC16AT3G as Obsolete. No official successor order code is recorded in the lifecycle data, meaning the manufacturer no longer produces this exact part and has not designated a drop-in replacement.

The DO-214AB (SMC) package is a surface-mount, JEDEC-standard outline with a gull-wing lead form. The cathode band identifies the unidirectional orientation; the anode is the tab side. Reflow profile follows standard lead-free solder profiles for the tin-plated terminations.

Frequently asked questions
