Description

The ST-4TB502 is a trimmer potentiometer that belongs to the product category of Electronic Component Model. It's designed by Teccor and it's part of their "HT" and "ST" Series of bilateral trigger diacs. This diac semiconductor is a full-wave or bidirectional thyristor that can be 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.
