Operating junction temperature range spans -55 °C to 175 °C, giving headroom for high-ambient environments like engine bays or industrial enclosures where the local air temperature reaches 85-105 °C. ## Compliance and sourcing posture ROHS3 compliant per STMicroelectronics — no restricted substances above the threshold limits, and no exemption expiry concerns for EU market placement.","metaTitle":"STD95N4F3 STMicroelectronics N-Channel MOSFET, 40V 80A DPAK","metaDescription":"STD95N4F3 N-channel 40V 80A MOSFET, STripFET III series, 6.5mOhm Rds(on), 54nC Qg, DPAK.
