Description

Electronic Component Model: ST-4ETA201 is a trimmer potentiometer used in various electronic devices. It belongs to the Teccor's "HT" and "ST" Series of bilateral trigger diacs. This diac semiconductor is a full-wave or bidirectional thyristor which is triggered from a blocking-to-conduction state for either polarity of applied voltage whenever the amplitude of applied voltage exceeds the breakover voltage rating of the diac. It features glass-passivated junctions to ensure long-term device reliability and parameter stability. The diac specifications listed in this data sheet are for standard products, but custom selections like close tolerance voltage symmetry are also available for custom design applications.
