Overview
The TMA166G-L is a Triac (Bidirectional Triode Thyristor) manufactured by Sanken Electric. It features a peak repetitive off-state voltage (VDRM) of 600 V and an RMS on-state current rating of 16 A at a case temperature of 100°C. The device supports a peak non-repetitive off-state voltage (VDSM) of 700 V and a surge on-state current of 168 A at 60 Hz. It operates within a junction temperature range of -40 to 125 °C and utilizes a 3-pin TO-220 package with a heatsink mounting pad.
Feature Summary
- Provides uniform switching for full-cycle AC power control applications
- Features improved commutation dv/dt performance compared to standard market products
- Offers high thermal dissipation capability through a small SIP package with integrated heatsink mounting
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
- Temperature control systems, light dimmers, and electric blankets
- General use switching mode power supplies (SMPS) for in-rush current control
Procurement Notes
Verify the component status before integration, as the datasheet explicitly marks the TMA166G-L as Not Recommended for New Designs. Confirm that the 3-pin fully molded SIP package with heatsink mount aligns with existing mechanical constraints. Ensure sourcing channels provide genuine Sanken Electric units to maintain specified reliability standards.
Selection Notes
Select this component for AC power control circuits requiring 16 A RMS current handling and 600 V blocking voltage. Consider the enhanced commutation dv/dt characteristics when driving capacitive loads or inductive motors. Verify that the thermal management design accommodates the 1.4 °C/W junction-to-case thermal resistance under maximum load conditions.
Part Context
This Triac belongs to Sanken Electric's bidirectional triode thyristor series designed for general-purpose AC switching. It serves as a robust alternative for legacy designs needing reliable full-cycle conduction. The device integrates a gate controller interface suitable for various industrial and consumer electronics control architectures.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Sanken Electric sales representatives for approved replacements or updated product recommendations due to the 'Not Recommended for New Designs' status.
