# BTA41-600B

**KTP** · TRIACs · TO-3P

BTA41-600B from KTP, in a TO-3P. 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 | T1 | passive | Main terminal 1 (T1) of the triac, which carries the on-state current up to IT(RMS) 40 A with VDRM/VRRM of 600 V. |
| 2 | T2 | passive | Main terminal 2 (T2) of the triac, which carries the on-state current up to IT(RMS) 40 A with VDRM/VRRM of 600 V. |
| 3 | G | input | Gate trigger input, requiring IGT max 50 mA in quadrants I-II-III and 70 mA in quadrant IV at VD=12 V, with VGT max 1.3 V and peak gate current IGM of 8 A. |
