RK1608B-TW

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

RK1608B-TW 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 (current return/reference terminal in the symbol), carrying up to 16 A RMS on-state current (TO-220B: at Tc=100°C).
2 T2 passive Main terminal T2 of the triac, rated for repetitive off-state/reverse voltage VDRM/VRRM of 600/800/1200 V depending on the voltage code and 16 A RMS on-state current.
3 G input Gate trigger terminal, with peak gate current IGM of 4 A (tp=20 µs, Tj=125°C), peak gate power PGM of 10 W and average gate power PG(AV) of 1 W.
