TMB206S-L

Overview

The TMB206S-L is a Triac (Bidirectional Triode Thyristor) from the TMB20x series manufactured by Sanken Electric. It features a peak repetitive off-state voltage of 600 V and an RMS on-state current rating of 20 A at a case temperature of 85°C. The device provides a peak non-repetitive off-state voltage of 700 V and an isolation voltage of 1800 V AC RMS between lead and case. It operates within a junction temperature range of -40 to 150 °C and utilizes a TO-220F package with a thermal resistance of 2.7 °C/W.

Feature Summary

• Small fully-molded SIP package designed for heatsink mounting to ensure high thermal dissipation and long life
• Enhanced isolation voltage of 1800 V AC RMS guaranteed for up to 1 minute
• Improved commutation dv/dt performance compared to standard market products
• Uniform switching characteristics suitable for full-cycle AC applications

Applications

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

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the specific ordering suffix matches the required packaging format, as variations exist between tube and bulk packing options. Ensure compliance with RoHS standards and check for UL Recognized Component status if safety certification is mandatory for the end application design.

Selection Notes

Select this component based on the 20 A RMS current requirement and 600 V blocking voltage capability. Consider the TO-220F package for effective heat sinking in high-power scenarios. Evaluate the improved commutation dv/dt specifications for circuits prone to rapid voltage changes. Verify that the operating junction temperature remains within the specified -40 to 150 °C range during continuous operation.

Part Context

This part belongs to the TMB20x series of Triacs produced by Sanken Electric. The series is characterized by its fully-molded SIP construction and enhanced electrical isolation properties. The TMB206S-L specifically denotes the 600 V variant within this lineup, designed for robust AC power control applications where reliability and uniform switching are critical requirements.

Replacement Considerations

Direct substitutes include other Triacs with similar 20 A ratings and 600 V blocking voltages in TO-220 packages. Verify pinout compatibility and thermal resistance values before substitution. Check datasheets for equivalent gate trigger currents and holding currents to ensure circuit stability without modification.
