CIQ1680

Tokmas · Thyristors (SCR)/Modules · TO-220

CIQ1680 from Tokmas, 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 A1 passive Main terminal 1, the reference terminal for both polarities of A2 in the datasheet's test conditions, and the terminal against which the 800 V VDRM/VRRM and 16 A IT(RMS) ratings apply.
2 A2 passive Main terminal 2; the datasheet specifies VDSM/VRSM of 800 V non-repetitive peak off-state voltage and dV/dt of 300 V/µs minimum at Tj = 150° C, with both polarities referenced to A1.
3 G input Gate trigger input; the datasheet gives IGT max 35 mA and VGT max 1.3 V for quadrants II-III at VD = 12 V, IGM max 4 A peak (tp = 20 µs) and PG(AV) max 1 W at Tj = 150° C.
