Frequently Asked Questions
How much continuous drain current can the STP140N8F7 handle and what package dissipates that heat?
The STP140N8F7 supports up to 90 A continuous drain current with a maximum power dissipation of 200 W in the TO-220 vertical through-hole package. This combination allows direct heat-sink mounting in motor drive stages operating at 80 V, maintaining junction temperature below 175°C under full load with adequate cooling.
For which high-current switching topologies is the STP140N8F7 most suitable compared to lower-rated alternatives?
The STP140N8F7 with its 80 V, 90 A rating is ideal for synchronous rectification in 48 V bus converters, H-bridge motor drives up to 3 kW, and phase-leg switches in 3-phase inverters. Lower-rated parts such as 60 A alternatives introduce higher conduction losses at currents above 60 A, whereas the STP140N8F7 maintains lower RDS(on) margin across the full 90 A range.
What lead time and availability should procurement teams plan for when sourcing the STP140N8F7?
The STP140N8F7 carries a factory lead time of approximately 26 weeks, making it critical to secure buffer stock for production ramps. At roughly $2.50 per unit at standard quantities, procurement teams should plan 6-month rolling forecasts and consider qualification of a secondary 80 V, 90 A N-channel MOSFET as a drop-in alternative to mitigate supply risk.
