T1610T-8I

STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB

T1610T-8I from STMicroelectronics, in a TO-220AB. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A1 passive Main terminal 1 (MT1/Anode 1). Reference terminal for A2 and gate; carries the AC load current together with A2. Blocking capability VDRM/VRRM = 800 V (Tj = 125 °C); on-state RMS current up to 16 A at Tc = 108 °C.
2 A2 passive Main terminal 2 (MT2/Anode 2). Second AC power terminal; electrically connected to the mounting tab. Rated 16 A RMS on-state current with VDRM/VRRM = 800 V; non-repetitive surge ITSM = 120 A (50 Hz, 20 ms).
3 G input Gate trigger input. Logic-level sensitive: IGT = 0.5 mA min / 10 mA max, VGT = 1.3 V max (VD = 12 V, RL = 30 Ω), allowing direct microcontroller drive. Peak gate current IGM = 4 A (tp = 20 µs); average gate power PG(AV) = 1 W. Triggers in quadrants I, II, and III.
TAB TAB passive Mounting tab, internally connected to A2 but ceramic-insulated from the heatsink (Vins = 2500 V rms, 1 minute). Recommended mounting torque 0.4-0.6 N·m. Thermal path: Rth(j-c) = 2.1 °C/W.
