SMP50 / SMTPA / TPA
TrisilTM for telecom equipment protection
Features

Bidirectional crowbar protection Voltage range from 62 V to 320 V Low capacitance from 12 pF to 20 pF @ 50 V Low leakage current : IR = 2 uA max Holding current: IH = 150 mA min Repetitive peak pulse current : IPP = 50 A (10/1000 us) SMB SMA (JEDEC DO-214AC) (JEDEC DO-214AA) SMTPA SMP50

Main applications
Telecommunication equipment such as:

Analog and digital line cards (xDSL, T1/E1, ISDN, ...) Terminals (phone, fax, modem, ...) and central office equipment

DO-15 TPA

Description
These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines. They are available in SMA, SMB and DO-15 packages.

Order codes
Part Number SMP50-xxx TPAxxx SMTPAxxx See Ordering Information on page 9 Marking

Benefits
Trisils are not subject to ageing and provide a fail safe mode in short circuit for a better protection. They 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 approved resin. SMA and SMB packages are JEDEC registered (DO-214AC and DO-214AA). Trisils are UL497B approved (file: E136224).
