TMA206S-L

Overview

The TMA206S-L is a Triac (Bidirectional Triode Thyristor) from the TMA20x series manufactured by Sanken Electric USA Inc. It features a peak repetitive off-state voltage (VDRM) of 600 V and a peak non-repetitive off-state voltage (VDSM) of 700 V. The device supports an RMS on-state current (IT(RMS)) of 20 A at a case temperature of 53°C, with a surge on-state current capability of 190 A at 50 Hz. It operates within a junction temperature range of -40°C to 125°C and provides an isolation voltage of 1800 V AC RMS. The component is housed in a 3-pin TO-220F package.

Feature Summary

• Small fully-molded SIP package designed for heatsink mounting to ensure high thermal dissipation and long life
• Provides increased isolation voltage of 1800 V AC RMS guaranteed for up to 1 minute between lead and case
• Features improved commutation dv/dt and (dv/dt)c characteristics for uniform switching

Applications

• Residential and commercial appliances including vacuum cleaners, rice cookers, TVs, and home entertainment systems
• White goods such as washing machines
• Office automation power control and photocopiers
• Motor control for small tools
• Temperature control, light dimmers, electric blankets, and general use switching mode power supplies

Procurement Notes

Verify the specific part number against official manufacturer documentation before procurement. Confirm that the component meets all required electrical specifications for the intended application. Check for any updates regarding the 'Not Recommended for New Designs' status. Ensure compliance with safety standards and handling precautions due to lethal voltage operation.

Selection Notes

Select the TMA206S-L when a 600 V off-state voltage rating is required. Consider the 20 A RMS current capacity and TO-220F package for thermal management needs. Evaluate the improved commutation dv/dt performance for applications requiring reliable switching under varying load conditions. Ensure the design accounts for the specified junction temperature limits and isolation requirements.
