Sensitive Triacs (0.8 To 8.0 Amps)

Category: Electronics, Littelfuse Inc, Trigger Devices

General Description

Teccor Electronics Inc. presents a series of sensitive gate triacs with current ratings up to 8 amperes, designed for AC switching and phase control applications such as motor speed adjustment, temperature modulation, and lighting controls. These triacs are suitable for both the domestic and industrial sectors, offering voltage capacities ranging from 200 to 600 volts. The product emphasizes gate control capabilities across all four quadrants, particularly the second and fourth, which is essential for circuits requiring positive-only or negative-only pulse inputs for AC current control across the device. Their operation is tailored to digital circuit interfacing.

The unique characteristic of this series is its sensitive gate functionality, ensuring reliable control over AC power. Despite their heightened sensitivity, users should be aware that triacs with lower holding current (I_t) values in the unfavored second and fourth quadrants may yield reduced dv/dt (rate of change of voltage) ratings, which is a critical consideration for certain applications.

Features

The series is distinguished by its electrically-isolated packaging options, such as the plastic TO-92 and THERMOTAB configurations. These designs ensure that the case or tab is insulated from the semiconductor chip, optimizing safety and reliability. Additionally, the non-isolated plastic TO-202 package variants are also offered. The triacs come with the convenience of tape-and-reel capability and tube packing to accommodate various logistical preferences.

Furthermore, all triacs in this lineup feature glass-passivated junctions that serve to prevent contaminant migration, which directly contributes to the product’s sustained reliability and parameter stability over time. Teccor Electronics has taken measures to certify the longevity and consistency of their sensitive triacs.

The triacs boast an impressive voltage capability of up to 600 volts and a surge capacity of up to 80 Amps, indicating robust performance ratings for a wide range of electrical environments and conditions.
