The TODV 640 ---> 1240 are four TOD series converters. They use high performance passivated glass technology with very high commutation levels and high surge current capability, which are suitable for power control on inductive loads (motors, transformers).
This datasheet describes the SGS-THOMSON TODV 640--->1240 alternistor, a high-performance passivated glass device for power control on inductive loads. It details electrical characteristics, absolute ratings, thermal resistances, and gate behavior. The device supports RMS currents up to 40A and surge currents up to 590A, with voltage ratings up to 1200V. Package dimensions and mechanical data are provided for RD91 plastic mounting.
