🔹 Overview: High-Power Triac Switching Element for Industrial AC Loads

The BTA41-800B is a high-power triangular rectifier switching element widely used for AC load switching in industrial and commercial applications. It features an 800V rated voltage, a 40A RMS rated current, and high surge current capacity.

🔹 Specific Applications of BTA41-800B in AC Load Switching

1️⃣ Industrial Heater Control

    Triangular reversible switches (TRIACs) allow switching of high-power resistive loads without mechanical contacts. ➡️ Using the BTA41-800B ensures precise switching cycles and sustained performance.

    2️⃣ Motor and Pump Switching

      Smooth switching prevents mechanical stress and extends motor life. ➡️ The BTA41-800B can handle high inrush currents, making it suitable for pumps, conveyors, and compressors.

      3️⃣ Lighting and HVAC Systems

      AC load switching for large lighting panels and HVAC fans requires low-noise, flicker-free performance. ➡️ The BTA41-800B provides reliable dv/dt and surge suppression.

              ‼️ FAQs

              Q: Is Semiware BTA41-800B compatible with ST BTA41-800B?

              Yes, the electrical parameters and package size are fully compatible, and it can be directly replaced in most AC switch designs.

              Q: What is the difference between BTA41-600B and BTA41-800B?

              The main difference is the blocking voltage:

              • 600B → 600V
              • 800B → 800V

              Q: What is the difference between BTA41 and BTA16?

              The main difference between BTA41 and BTA16 is their current handling capability.

              • BTA16 is rated for 16A RMS current and is typically used in medium-power applications such as household appliances, small heaters, and light motor control.
              • BTA41 is rated for 40A RMS current and is designed for heavy-duty applications such as industrial heaters, large motors, HVAC systems, and high-power AC load switching.
