TMA166S-L

Overview

The TMA166S-L is a Triac (Bidirectional Triode Thyristor) from the TMA16xS series, manufactured by Sanken Electric Co., Ltd. and distributed by Allegro MicroSystems, Inc. It features a peak repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current (IT(RMS)) of 16 A at a case temperature of 66°C. The device provides an isolation voltage of 1800 V AC RMS between lead and case for one minute. It operates within a junction temperature range of -40 to 125°C and utilizes a 3-pin fully molded SIP package (TO-220F).

Feature Summary

Small fully-molded SIP package with heatsink mounting capability for high thermal dissipation.
Increased isolation voltage of 1800 V AC RMS guaranteed for up to 1 minute.
Improved commutation dv/dt and (dv/dt)c characteristics compared to other products.
Uniform switching performance designed for reliable full-cycle AC applications.

Applications

Residential and commercial appliances such as vacuum cleaners, rice cookers, TVs, and home entertainment systems.
White goods including 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 (SMPS).

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the part number matches the specific datasheet version SSE-22887. Ensure storage conditions comply with standard temperature and humidity requirements to prevent lead rust or solderability issues before installation.

Selection Notes

Select this component for AC power control circuits requiring 600 V blocking voltage and 16 A continuous current handling. Consider the TO-220F package for effective heat sinking. Evaluate thermal resistance and derating requirements based on the maximum operating junction temperature of 125°C and ambient conditions.

Part Context

This Triac belongs to the TMA16xS series, which includes variants with different voltage ratings such as the TMA164x (400 V). The TMA166S-L specifically denotes the 600 V rating within this family. The 'S' indicates a specific packaging or variant configuration, while 'L' may denote lead-free compliance or specific packing details.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative Triacs with similar electrical specifications.

FAQ

What is the peak non-repetitive off-state voltage (VDSM) for the TMA166S-L?

The peak non-repetitive off-state voltage (VDSM) for the TMA166S-L is 700 V when the gate reference is open (RGREF = ∞).

How does the TMA166S-L handle surge currents?

It can withstand a surge on-state current (ITSM) of 168 A for a 60 Hz full cycle sine wave and 160 A for a 50 Hz full cycle sine wave, with an initial junction temperature of 125°C.
