VDS=100V: Suitable for 24V/36V/48V and higher systems, providing ample voltage spike margin, significantly reducing avalanche breakdown risk, and enhancing system robustness.
VGS=±20V: Compatible with various logic-level drives, can be flexibly used with PWM controllers, gate driver ICs, or MCUs without complex level shifting.
Vth=2.5V (Typical): Moderate threshold voltage balances noise immunity and drive compatibility, ensuring stable conduction over a wide temperature range.
RDS(on)=10mΩ @ VGS=10V: Ultra-low on-resistance minimizes conduction losses at full load, effectively reducing temperature rise, simplifying thermal design, or increasing power density.
RDS(on)=23mΩ @ VGS=4.5V: Maintains low on-resistance even with low-voltage drive, providing extra margin for 5V logic drive scenarios.
ID=100A: Ample continuous current capability to handle high-power loads and short-term current surges, suitable for motors, power supplies, and other heavy-load applications.
Package TO263 (DPAK): Industry-standard high-current SMD package with an integrated heatsink pad for enhanced thermal transfer, compatible with mainstream SMT processes for mass production.
Domain and module applications：
High-Power DC-DC Converters: In synchronous rectification or main switch applications, the 10mΩ-level low on-resistance significantly reduces conversion losses, improving heavy-load efficiency and facilitating module miniaturization.
Server & Telecom Power Supplies: The 100V withstand voltage and 100A current capability support efficient PFC or LLC topologies, meeting the demands of high-power-density power modules.
Motor Drive & Control: Low PWM switching losses and low conduction voltage drop make it suitable for 48V and below BLDC/PMSM motor drives, resulting in lower controller temperature rise.
Automotive Power Systems: In 12V/24V/48V automotive bus environments, ample voltage margin and a wide Safe Operating Area (SOA) handle inductive load spikes reliably.
Battery Protection & Energy Storage: Strong high-current switching capability, fast response during overcurrent/short circuit, low on-resistance reduces self-heating on the protection board, extending battery cycle life.
UPS & Industrial Power Supplies: The synergy of high withstand voltage and low on-resistance improves inverter efficiency and load capacity, suitable for Uninterruptible Power Supplies and industrial auxiliary power.
Power Tools & High-Power Loads: 100A continuous current supports high-power output, and the TO263 package facilitates thermal design, meeting demanding operating conditions.
Selection Summary: The STH80N10LF7-2AG-VB excels in high-current, medium-voltage, and high-reliability applications. The combination of 10mΩ-level on-resistance and 100A current capability makes it a preferred device for efficient power conversion and power control, especially for projects with specific requirements for thermal performance, current handling, and long-term stability.
