The SPT15N120F1T8TL with TO-247-3 IGBTs ROHS is a power transistor that is manufactured by SPS. It is a silicon N-channel power transistors with built-in annealing diodes, an exceptionally low on-state resistance and a very low gate charge. This makes it well suited for the most challenging motor control and high frequency switching application. Additionally, this part is RoHS compliant, meaning it is free of hazardous substances like lead and mercury.
