TISP43xxMMAJ/BJ Bidirectional Thyristor Overvoltage Protectors are designed for telephone line applications. They can limit overvoltages on the telephone line and protect telephone line. The devices meet ITU-T Recommendation K.21 10/700 AC Induction and Contact, FCC Part 68 (TIA/EIA-IS-968) Type A & B Surge, UL 60950 and CSA 22.2 No.60950 Clause 6. Power Cross, Telcordia GR-1089-CORE 2/10 and 10/1000 AC Induction and Contact specifications.
This handbook describes the TISP43xxMMAJ/BJ series of bidirectional thyristor overvoltage protectors. It lists the applicable standards (ITU‑T K.21, FCC Part 68, UL 60950, CSA 22.2, Telcordia GR‑1089‑CORE) and the typical applications such as POTS and ADSL modems.
The document includes absolute maximum ratings, overload ratings, recommended operating conditions, electrical characteristics, mechanical dimensions, and tape packaging details for both SMA (DO‑214AC) and SMB (DO‑214AA) surface‑mount packages.
