BTA16-800CW from WEIDA, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | T1 | passive | Main terminal 1 of the triac, the 'T1(1)' terminal in the symbol; the device is rated for IT(RMS) 16 A and VDRM/VRRM of 800 V for this MPN. |
| 2 | T2 | passive | Main terminal 2 of the triac, the 'T2(2)' terminal in the symbol; in the insulated TO-220A package the tab is isolated from all three terminals (2500 VRMS rated). |
| 3 | G | input | Gate trigger terminal, 'G(3)'; the CW grade has IGT max 35 mA (quadrants I-II-III) at VD=12V, RL=33Ω with VGT max 1.3 V. |
