The 70TPS. SAFEIR series of silicon controlled rectifiers are specifically designed for high and medium power switching and phase control appli- cations. Typical applications are in input rectification (soft start) or AC-Switches or high current crow-bar as well as others phase-control circuits.
The 70TPS SAFEIR series silicon‑controlled rectifiers are designed for high and medium power switching and phase‑control circuits such as soft‑start input rectification, AC‑switches, and crow‑bar protection. They are intended to be used with International Rectifier diodes, switches, and output rectifiers in identical package outlines.
The bulletin lists major electrical ratings, thermal‑mechanical specifications, and mechanical dimensions, including on‑state current limits, surge current capability, forward voltage drop, thermal resistance values, and junction temperature range. Additional ordering information and reference tables are provided for designers.
| Peak Surge Current (10 ms sine pulse) | 1400 A |
