Z0409MB from STMicroelectronics, in a DPAK. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | Gate terminal for triggering the triac with maximum peak gate current 1.2 A (tp = 20 µs) and maximum power dissipation 0.5 W. |
| 2 | A1 | bidirectional | Anode 1 main current terminal rated for maximum 4 A RMS on-state current and 600 V repetitive peak off-state voltage (Tj = 125 °C). |
| 3 | A2 | bidirectional | Anode 2 main current terminal rated for maximum 4 A RMS on-state current and 600 V repetitive peak off-state voltage (Tj = 125 °C), connected to package tab for heat dissipation. |
