AVS08CBI

Overview

The AVS08CBI is an automatic mains selector kit designed for switch-mode power supplies (SMPS) under 200 W. It comprises two components: the AVS1BCP08 controller in a DIP-8 package and the AVS08CBI TRIAC in a TO-220AB insulated package. The TRIAC provides a repetitive peak off-state voltage of ±500 V and an RMS on-state current of 5 A at a case temperature of 95°C. The system supports full compatibility with 50/60 Hz mains frequencies, features an integrated voltage regulator, and includes parasitic filtering to ensure high efficiency and safety switching.

Feature Summary

Insulated TRIAC package providing 2500V(RMS) isolation
Integrated voltage regulator within the controller
Optimized triggering pulse train for enhanced immunity against disturbances

Applications

Automatic selection between 110V and 220V AC mains inputs
Power supply systems with output ratings below 200 W
Equipment requiring high-efficiency and safe voltage switching

Procurement Notes

Verify that the specific part number corresponds to the insulated TRIAC variant (AVS08CBI) rather than the uninsulated version. Confirm the accompanying controller component is the AVS1BCP08. Ensure the application design accounts for the specified thermal resistance values and operating temperature range of 0 to +70°C for the complete kit assembly.

Selection Notes

Select the AVS08CBI when electrical isolation is required between the control circuitry and the mains-connected TRIAC. This insulated package variant is necessary for applications demanding 2500V(RMS) isolation. Verify that the SMPS power consumption remains strictly below the 200 W limit defined for this kit's operational specifications.

Part Context

The AVS08CBI serves as the TRIAC component within the broader AVS08 automatic voltage switch family. While the AVS08CB offers an uninsulated package, the CBI suffix specifically denotes the insulated TO-220AB configuration. This distinction ensures appropriate safety isolation levels are maintained for different enclosure and regulatory requirements in low-power AC mains applications.
