TMA106S-L

Overview

The TMA106S-L is a Triac (Bidirectional Triode Thyristor) designed for AC power control in full-cycle applications. 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 on-state current (IT(RMS)) of 10 A at a case temperature of 85°C, with a surge on-state current capability of 100 A at 50 Hz. It provides an isolation voltage of 1800 V AC RMS between the lead and case. Packaged in a 3-pin SIP (TO-220F), it offers a junction-to-case thermal resistance of 3.6 °C/W and operates within a junction temperature range of -40 to 125 °C.

Feature Summary

• Enhanced isolation voltage of 1800 V AC RMS between lead and case
• Improved commutation dv/dt performance for reliable switching
• Small fully-molded SIP package with heatsink mounting for high thermal dissipation
• Uniform switching characteristics suitable for full-cycle AC applications

Applications

• Residential and commercial appliances such as vacuum cleaners and rice cookers
• White goods including washing machines
• Office automation power control and photocopiers
• Motor control for small tools
• Temperature control, light dimmers, and electric blankets

Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the part number suffix matches the required voltage rating. Ensure storage conditions remain within standard temperature and humidity ranges to prevent lead rust or solderability issues before installation.

Selection Notes

Select this component for general-purpose mains power AC switching where 600 V blocking capability is required. Consider the TO-220F package for effective heat dissipation when operating near the 10 A RMS limit. Verify that the application circuit accounts for the specified surge current ratings and thermal resistance values under maximum load conditions.

Part Context

This device belongs to the TMA10x series of Triacs manufactured by Sanken Electric Co., Ltd. and distributed by Allegro MicroSystems, Inc. The series includes variants with different voltage ratings, such as the TMA104x for 400 V applications. The TMA106S-L specifically targets higher voltage requirements while maintaining the series' reliability and thermal performance standards.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should consult Sanken Electric or Allegro MicroSystems sales representatives for approved alternatives if this component is no longer recommended for new designs.
