1 / 10 page ® 1/10 SMP50 / SMTPA / TPA TRISIL™ FOR TELECOM EQUIPMENT PROTECTION REV. 1 SMA (JEDEC DO-214AC) SMP50 SMB (JEDEC DO-214AA) SMTPA DO-15 TPA November 2004 FEATURES ■ Bidirectional crowbar protection ■ Voltage range from 62V to 270V ■ Low capacitance from 12pF to 20pF @ 50V ■ Low leakage current : IR = 2µA max ■ Holding current: IH = 150 mA min ■ Repetitive peak pulse current : IPP = 50 A (10/1000µs) MAIN APPLICATIONS Telecommunication equipment such as: ■ Analog and digital line cards (xDSL, T1/E1, ISDN, ...) ■ Terminals (phone, fax, modem, ...) and central office equipment 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 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).
