S6025LTP

Littelfuse · TRIACs · TO-220

S6025LTP from Littelfuse, 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 CATHODE passive Cathode main terminal of the 25 A SCR (IT(RMS) 25 A at TC=75°C for Sxx25L, 600 V VDRM/VRRM for S60).
2 ANODE passive Anode main terminal of the SCR, blocking up to 600 V (VDRM/VRRM) for the S60 voltage code; the mounting tab is isolated from it in the L package.
3 GATE input Gate trigger input, with IGT max 35 mA and VGT max 1.5 V at VD=12 V, RL=30 Ω, TJ=25°C.
