SMA
(JEDEC DO-214AC)
SCHEMATIC DIAGRAM
DESCRIPTION
The SMP50-xxx series has been designed to
protect telecommunication equipment against
lightningandtransientinduced byACpower lines.
The package/ die sizeratio has been optimizedby
using the SMA package.
BENEFITS
Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. Trisils
are used to help equipment to meet various standards such as UL1950, IEC950 / CSA C22.2, UL1459
and FCC part 68. Trisils have UL94 V0resinapproved.SMA package is JEDEC registred. (Trisils are UL
497B approved - file: E136224).
