| Market Reality | - | This eight-pin row is how inverter, servo and welder drive boards cross the isolation barrier to fire their IGBTs: TLP250 from Toshiba, HCPL-3120/A3120 from the Avago lineage, FOD3120 from the Fairchild line - four houses, one socket, and a repair literature that swaps them by name. The selection axis is output current (TLP250 at a 1.5A peak against the 2.5A class of its successors) and input threshold (the 3120 triggers from a lower LED current), and the design axis is the negative gate rail that keeps Miller capacitance from re-triggering the IGBT. In repair, the row behaves; what re-fails is the rail and the bypass capacitor the procedure keeps forgetting. |
