**MSKSEMI** · TRIACs · TO-220

BTA08-600B from MSKSEMI, 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 | T1 | passive | Main terminal T1 (cathode), with repetitive peak off-state voltage VDRM of 600/800 V (Tj=25℃) and RMS on-state current IT(RMS) of 8 A (TC=95℃). |
| 2 | T2 | passive | Main terminal T2 (anode), with repetitive peak off-state voltage VDRM of 600/800 V and non-repetitive surge peak on-state current ITSM of 80 A (full cycle, F=50Hz). |
| 3 | G | input | Gate with a parallel resistor between Gate and Cathode; peak gate current IGM is 4 A and peak gate power PGM is 5 W. |
