N-channel 40V - 0.0042Ω - 18A - PowerSO-8™
STripFET™III Power MOSFET for DC-DC conversion
General features
Type
STSJ80N4LLF3
VDSS
40V
RDS(on)
0.005Ω
ID
18A(1)
1. This value is rated according to Rthj-pcb
■ Optimal RDS(on) x Qg trade-off @ 4.5V
■ Switching losses reduced
■ Low threshold device
■ Improved junction-case thermal resistance
Description
This series of product utilizes the latest advanced
design rules of ST’s proprietary STripFET™
technology. This process coupled to unique
metallization techniques realizes the most
advanced low voltage Power MOSFET in SO-8
ever produced. The exposed slug reduces the
Rthj-c improving the current capability.
