RS0408A-CW from Shenzhen Haoruijia Elec, in a TO-220AB-3. 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 T1 of the triac, the gate reference terminal, carrying up to 4 A RMS on-state current (insulated TO-220AB, Tc=90°C). |
| 2 | T2 | passive | Main terminal T2 of the triac, rated for VDRM/VRRM of 800V for the 08 grade and 4 A RMS, and electrically isolated from the heat-sink tab (2500V RMS isolation for the A version). |
| 3 | G | input | Gate trigger input, with IGT max 35 mA (CW grade, quadrants I-II-III, VD=12V RL=33Ω) and VGT max 1.5V, peak gate current IGM 4A for tp=20us. |
