RS0408A-CW

Shenzhen Haoruijia Elec · Thyristors (SCR)/Modules · TO-220AB-3

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.
