The ±20 V Vgs max gives headroom for 12 V gate drive in automotive pre-driver circuits. ## Temperature range and thermal budget Junction temperature range is -55 °C to 150 °C, covering under-hood automotive and industrial enclosures. Maximum power dissipation is 139 W at the case — real-world dissipation depends on the PCB copper area under the 8-VSON-CLIP pad. The 2.2 V gate threshold at 250 µA means the MOSFET is fully off below 2 V, but the threshold shifts with temperature; at -55 °C it rises, so a 5 V gate drive is the safe minimum for cold starts.","metaTitle":"CSD18512Q5B NexFET N-Channel MOSFET, 40 V, 211 A, 1.6 mOhm","metaDescription":"Texas Instruments CSD18512Q5B NexFET N-Channel MOSFET, 40 V drain, 211 A continuous, 1.6 mOhm Rds(on) at 10 V.
