1 SMP5 / SMTPA / TPA TRISIL FOR TELECOM EQUIPMENT PROTECTION FEATURES Bidirectional crowbar protection Voltage range from 62V to 27V Low capacitance from 12pF to 5V Low leakage current : I R = 2µA max Holding current: I H = 15 ma min Repetitive peak pulse current : I PP = 5 A (1/µs) MAIN APPLICATIONS Telecommunication equipment such as: Analog and digital line cards (xdsl, T1/E1, ISDN,...) Terminals (phone, fax, modem,...) and central office equipment SMA (JEDEC DO-214AC) SMP5 SMB (JEDEC DO-214AA) SMTPA 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. 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 UL195, IEC95 / CSA C22.2, UL1459 and FCC part 68. Trisils have UL94 V approved resin. SMA and SMB packages are JEDEC registered (DO-214AC and DO-214AA). Trisils are UL497B approved (file: E136224).
