FEATURES
SMA
(JEDEC DO-214AC)
The SMP30-xxx series has been designed to
protect telecommunication equipment against
lightning and transient induced by AC power lines.
The package / die size ratio has been optimized by
using the SMA package.
DESCRIPTION
SCHEMATIC DIAGRAM
TELECOM EQUIPMENT PROTECTION: TRISILTM
November 2002 - Ed: 4B
Telecommunication equipment such as
s
Analog and digital line cards (xDSL, T1/E1,
ISDN...).
s
Terminals (phone, fax, modem...) and central
office equipment.
MAIN APPLICATIONS
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 V0 resin approved. SMA package is JEDEC registred. (Trisils are UL
497B approved - file: E136224).
