ROHS3 compliant. No official second-source or successor is listed in the Infineon cross-reference database for this exact order code.","metaTitle":"IRFB4229PBF HEXFET N-Channel MOSFET, 250 V, 46 A, TO-220","metaDescription":"IRFB4229PBF N-channel HEXFET MOSFET, 250 Vdss, 46 A continuous, 46 mOhm Rds(on) at 10 V.
