Description
TMA8x Series Triac (Bidirectional Triode Thyristor)
Features and Benefits
▪ Exceptional reliability ▪ Small fully-molded SIP package with heatsink mounting for high thermal dissipation and long life ▪ VDRM of 400 or 600 V ▪ 8 ARMS on-state current ▪ Uniform switching ▪ UL Recognized Component (File No.: E118037) (suffix I)
Description
This Sanken triac (bidirectional triode thyristor) is designed for AC power control, providing reliable, uniform switching for full-cycle AC applications. In comparison with other products on the market, the TMA8x series provides increased isolation voltage (1800 VACRMS), guaranteed for up to 1 minute, and greater peak nonrepetitive off-state voltage, VDSM (700 V). In addition, commutation dv/dt and (dv/dt)c are improved.
Package: 3-pin SIP (TO-220F)
Applications
▪ Residential and commercial appliances: vacuum cleaners, rice cookers, TVs, home entertainment ▪ White goods: washing machines ▪ Office automation power control, photocopiers ▪ Motor control for small tools ▪ Temperature control, light dimmers, electric blankets ▪ General use switching mode power supplies (SMPS)
Not to scale
Typical Applications
Halogen Lamp
Gate Controller
Heater control (for example, LBP. PPC, MFP)
Two-phase motor control (for example, washing machine)
In-rush current control (for example, SMPS)
