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

TN4015H-6I 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 | K | passive | Cathode, the SCR current return terminal, carrying up to 40 A RMS on-state current (IT(RMS) at Tc = 82 °C). |
| 2 | A | passive | Anode, the SCR power terminal, with repetitive peak off-state voltage VDRM/VRRM of 600 V and 40 A RMS on-state current. |
| 3 | G | input | Gate trigger input, requiring IGT max 15 mA and VGT max 1.3 V at VD = 12 V, with maximum peak reverse gate voltage VRGM of 5 V. |
