NYC0102BLT1G

Littelfuse · Thyristors (SCR)/Modules · SOT-23

NYC0102BLT1G from Littelfuse, 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 G input Gate of the SCR: gate trigger current is specified at 200 (µA as printed; the micro sign is lost in extraction) max, gate trigger voltage at 0.8 V max, and reverse gate voltage VRGM is 8.0 V max with peak gate power PGM of 0.1 W and peak gate current IFGM of 0.5 A.
2 A passive Anode of the SCR: peak repetitive off-state voltage VDRM/VRRM is 200 V (positive gate voltage must not be applied concurrent with negative anode potential), with on-state RMS current IT(RMS) of 0.25 A and peak non-repetitive surge current ITSM of 7.0 A.
3 K passive Cathode of the SCR, the reference terminal for the gate; characterization uses a gate-to-cathode resistor RGK of 1 kΩ (printed as '1 k' in extraction).
