FEATURES

SMA

(JEDEC DO-214AC)

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.

DESCRIPTION

SCHEMATIC DIAGRAM

TELECOM EQUIPMENT PROTECTION: TRISIL™

November 2002- Ed: 3B

Telecommunication equipment such as

■

Analog and digital line cards (xDSL, T1/E1,

ISDN...).

■

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 V0resinapproved.SMA package is JEDEC registred. (Trisils are UL

497B approved - file: E136224).
