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) 28105.12 TMA8x Series Selection Guide Part Number TMA84(I) TMA84S-L TMA86(I) TMA86S-L Triac (Bidirectional Triode Thyristor) VDRM (V) 400 400 600 600 UL-Recognized Component Yes – Yes – Package 3-pin fully molded SIP with heatsink mount Packing 50 pieces per tube Absolute Maximum Ratings Characteristic Peak Repetitive Off-State Voltage Symbol VDRM Notes Rating 400 600 500 700 1800 8 84 80 32 2 5 0.5 –40 to 125 –40 to 125 Units V V V V V A A A A2 • s A W W ºC ºC TMA84x TMA86x TMA84x TMA86x RGREF = ∞ RGREF = ∞ Peak Non-Repetitive Off-State Voltage Isolation Voltage RMS On-State Current VDSM VISO IT(RMS) AC RMS applied for 1 minute between lead and case 50/60 Hz full cycle sine wave, total Conduction angle (α+) + (α–) = 360°, TC = 92°C f = 60 Hz Full cycle sine wave, peak value, non-repetitive, initial TJ = 125°C Surge On-State Current I2t Value for Fusing Peak Gate Current Peak Gate Power Dissipation Average Gate Power Dissipation Junction Temperature Storage Temperature ITSM f = 50 Hz I2t IGM PGM PGM(AV) TJ Tstg Value for 50 Hz half cycle sine wave, 1 cycle, ITSM = 80 A f ≥ 50 Hz, duty cycle ≤ 10% f ≥ 50 Hz, duty cycle ≤ 10% TJ < TJ(max) Thermal Characteristics May require derating at maximum conditions Characteristic Package Thermal Resistance (Junction to Case) Symbol RθJC For AC Test Conditions Value 3.7 Units ºC/W Pin-out Diagram T2 Number 1 Terminal List Table Name T1 T2 G Function Main terminal, gate referenced Main terminal connect to signal side Gate control G T1 2 3 1 2 3 All performance characteristics given are typical values for circuit or system baseline design only and are at the nominal operating voltage and an ambient temperature, TA, of 25°C, unless otherwise stated.
