BTB41-600BRG

JSMSEMI · TRIACs · TO-3P-3

BTB41-600BRG from JSMSEMI, in a TO-3P-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 A1 passive Main terminal A1 (reference terminal for gate and A2 polarity); the datasheet's TOP3 (BTB41) drawing shows the leads in the order A1, A2, G.
2 A2 passive Main terminal A2, which is also connected to the metal tab (non-insulated TOP3, BTB41); rated 40 A RMS (IT(RMS)) and VDRM/VRRM of 600 V for this part.
3 G input Gate trigger input with IGT max 50 mA in quadrants I-II-III (100 mA in IV) and VGT max 1.3 V at VD = 12 V, RL = 33 Ω.
