Product introduction：
BUK7515-100A,127-VB is a Single N-MOS optimized for high-power switching scenarios, with Trench technology balancing low switching losses and high reliability. The TO220 package strikes a balance between thermal performance and ease of installation. The combination of 100V withstand voltage, 70A current capacity, and 17mΩ on-resistance makes it an ideal cost-effective alternative to traditional DPAK or D2PAK packaged devices, particularly suited for applications with strict thermal and reliability requirements, such as industrial power supplies, motor drives, and automotive systems.

VDS=100V: Suitable for 24V/48V/60V systems, provides ample voltage spike margin, reduces avalanche breakdown risk.
VGS=±20V: Compatible with 5V~12V logic levels, can directly interface with driver ICs or MCUs, simplifying gate drive design.
Vth=1.8V (Typical): Medium threshold voltage, balances noise immunity and drive compatibility, suitable for wide voltage drive scenarios.
RDS(on)=17mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load conduction loss, allows for smaller heatsinks.
ID=70A: Ample continuous current margin, can handle peak load demands of high-power motors and power converters.
Package TO220: Low thermal resistance, short heat dissipation path, supports high continuous power output, easy PCB mounting and maintenance.
Domain and module applications：
Application Areas and Modules
Industrial Switching Power Supply: Low on-resistance improves full-load efficiency; TO220 package facilitates heatsink attachment, suitable for AC-DC power stages.
Motor Drive and Control: 70A high-current capability covers industrial motors, power tools, and robot joint drives; low PWM switching loss.
Automotive Power System: 100V withstand voltage adapts to 12V/24V automotive buses, handling load dump and inductive load spikes with high reliability.
DC-DC Converter: Replaces Schottky diodes in synchronous rectification; heavy-load efficiency can be improved by 2~3%, benefiting module power density.
UPS and Energy Storage System: Lower temperature rise in low-voltage, high-current switching scenarios; supports continuous high-power charge/discharge, extending system life.
Battery Protection Module: Fast switching characteristics ensure reliable turn-off during overcurrent/short circuit; low internal resistance reduces self-heating of the protection board.
Selection Summary: BUK7515-100A,127-VB achieves a balance between withstand voltage, current-carrying capacity, and on-resistance. It is a cost-effective general-purpose choice for 100V high-voltage, high-current switching applications, particularly suitable for industrial and automotive projects with strict requirements for heat dissipation and long-term reliability.
