SCRS
DESCRIPTION
Passivated, sensitive gate thyristors in a plastic envelope,
intended for use in general purpose switching and phase control
applications. These devices are intended to be interfaced
directly to microcontrollers, logic integrated circuits and other
low power gate trigger circuits.

Note: 1. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.
2. 1 Although not recommended, off-state voltages up to 800V may be applied without damage, but the
thyristor may switch to the on-state. The rate of rise of current should not exceed 15 A/μs.
