SMP50-100 STMicroelectronics

SMP50 / SMTPA / TPA Trisil 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 : I = 2 A max R SMB SMA (JEDEC DO-214AA) Holding current: I = 150 mA min (JEDEC DO-214AC) H SMTPA SMP50 Repetitive peak pulse current : I = 50 A (10/1000 s) PP Main applications Telecommunication equipment such as: Analog and digital line cards (xDSL, T1/E1, DO-15 ISDN, ...) TPA Terminals (phone, fax, modem, ...) and central office equipment Order codes Description Part Number Marking These Trisil series have been designed to protect telecommunication equipment against lightning SMP50-xxx and transient induced by AC power lines. See Ordering Information TPAxxx on page 9 They are available in SMA, SMB and DO-15 SMTPAxxx packages. Schematic Diagram 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).
