MCR100G-6-AE3-R

UTC Unisonic Tech · Thyristors (SCR)/Modules · SOT-23

MCR100G-6-AE3-R from UTC Unisonic Tech, in a SOT-23. 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 K passive Cathode of the SCR; the main current return terminal, and the reference for the gate-cathode path (RGK of 1 kΩ is specified in the blocking tests).
2 G input Gate trigger input; limits are peak forward gate current IGM 1 A and peak reverse gate voltage VGRM 5 V (pulse width ≤1.0 µs), with forward average gate power PG(AV) 0.01 W.
3 A passive Anode, the main power terminal; for MCR100-6 the peak repetitive off-state voltage VDRM/VRRM is 400 V, and positive gate voltage must not be applied while the anode is at negative potential.
