BTB24-800BWRG

STMicroelectronics · Thyristors (SCR)/Modules · TO-220AB

BTB24-800BWRG from STMicroelectronics, in a TO-220AB. 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 (MT1), the reference terminal for the A2 voltage and the gate; the datasheet gives the BTB24 as 25 A IT(RMS) with VDRM/VRRM of 600/800 V.
2 A2 passive Main terminal A2 (MT2), also connected to the non-insulated metal tab on the BTB24; rated for 25 A RMS on-state current and VDRM/VRRM of 600/800 V.
3 G input Gate trigger input; IGT is 50 mA max for the BW snubberless version at VD = 12 V, RL = 33 Ω, and VGT is 1.3 V max.
