They typically are placed behind some type of current-limiting device. Common applications include: • Central office line cards (SLICs) • T-1/E-1, ISDN, and xDSL transmission equipment • Customer Premises Equipment (CPE) such as phones, modems, and caller ID adjunct boxes • PBXs, KSUs, and other switches • Primary protection including main distribution frames, five-pin modules, building entrance equipment, and station protection modules • Data lines and security systems • CATV line amplifiers and power inserters • Sprinkler systems REV.2015.02.01 01 | www.spsemi.cn Thyristor/SMB Series P Device （Ｓ series） DO-214AA P solid state protection devices protect telecommunications equipment such as modems, line cards, fax machines, and other CPE. P devices are used to enable equipment to meet various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).

Upon application of a voltage exceeding the switching voltage (VS), P devices crowbar and simulate a short circuit condition until the current flowing through the device is either interrupted or drops below the P device’s holding current (I H). Once this occurs, P devices reset and return to their high off-state impedance.
