BIDIRECTIONAL CROWBAR PROTECTION

VOLTAGE RANGE FROM 62V TO 270V

LOW CAPACITANCE FROM 15PF TO 30PF TYP.@50V

LOW LEAKAGE CURRENT: IR = 2uA MAX.

HOLDING CURRENT: IH = 150 mA MIN.

REPETITIVE PEAK PULSE CURRENT: IPP = 50A (10/1000uS)

MAIN APPLICATIONS

TELECOMMUNICATION EQUIPMENT SUCH AS:

ANALOG AND DIGITAL LINE CARDS (xDSL,T1/E1,ISDN..)

TERMINALS (PHONE, FAX,MODEM…) AND CENTRAL

OFFICE EQUIPMENT.

DESCRIPTION

THE SMTPAxxx

SERIES HAS BEEN DESIGNED TO PROTECT

TELECOMMUNICATION EQUIPMENT AGAINST LIGHTNING AND

TRANSIENT INDUCED BY AC POWER LINES.

CASE:DO-214AA (SMB)

THE PACKAGE / DIE SIZE RATIO HAS BEEN OPTIMIZED BY USING

DIMENSIONS IN INCHES AND (MILLIMETERS)

THE SMB 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

SUCH AS UL1950, IEC950/CSA C22.2, UL1459 AND FCC PART68.

TRISILS HAVE UL94 V0 RESIN APPROVED. SMB PACKAGE IS JEDEC

REGISTERED.( TRISILS ARE UL497B APPROVED – FILE:E136224)
