Overview
The TMA166B-L is a Triac (Bidirectional Triode Thyristor) manufactured by Sanken Electric USA Inc. It features a peak repetitive off-state voltage of 600 V and an on-state current rating of 16 A RMS at a case temperature of 98°C. The device operates within a junction temperature range of -40 to 125°C and includes a peak non-repetitive off-state voltage of 700 V. It utilizes a 3-pin SIP (TO-3PF) package with flange mount capabilities for thermal dissipation.
Feature Summary
- Provides high isolation voltage rated at 2000 V AC RMS between lead and case.
- Features uniform switching characteristics suitable for full-cycle AC applications.
- Includes UL Recognized Component status for specific suffix variants.
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.
Procurement Notes
Verify the component against official datasheets to confirm electrical ratings and physical dimensions. Ensure compliance with safety standards for lethal voltage applications. Check storage conditions to prevent lead rust or solderability issues before installation.
Selection Notes
Select this component based on its 600 V off-state voltage and 16 A RMS current capacity. Consider the TO-3PF package for heatsink mounting requirements. Verify that the operating junction temperature range meets the application's thermal constraints.
Part Context
This part belongs to the TMA16xB series of Triacs designed for AC power control. It offers improved commutation dv/dt performance compared to other market products. The series provides increased isolation voltage and greater peak non-repetitive off-state voltage for reliable operation.

FAQ
What is the maximum surge on-state current for the TMA166B-L?
The peak non-repetitive surge on-state current is 190 A at 60 Hz and 180 A at 50 Hz, with an initial junction temperature of 125°C.
How is the gate trigger voltage specified for different quadrants?
The typical gate trigger voltage is 1.5 V for Quadrant I (T2+, G+), Quadrant II (T2+, G–), and Quadrant III (T2–, G–).
What are the recommended tightening torques for heatsink mounting?
The recommended tightening torque for mounting screws is 0.686 to 0.882 N•m (7 to 9 kgf•cm) to avoid thermal resistance increase or mechanical deformation.
