This document is a technical datasheet for the Powerex TA20 Series Silicon Controlled Rectifiers (SCR). These devices are designed for phase control applications such as power supplies, battery chargers, motor control, light dimmers, and VAR generators. The series features all-diffused Phase-Pak construction with field-proven amplifying gate technology.
| Average On-State Current | 1600-1800 Amperes Avg |
|---|---|
| Voltage Range | 100-2200 Volts |
| RMS On-State Current | 2500-2820 Amperes |
| Peak Gate Power Dissipation | 16 Watts |
