A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a voltage-controlled power switching device featuring fast switching speed, low power consumption, and simple driving. Mainstream types are classified into N-Channel and P-Channel; by process technology, there are Trench MOS, SGT MOS, VD MOS, SJ MOS, etc.; by material, there are silicon-based products and wide-bandgap products such as SiC and GaN, suitable for a wide range of power circuits.
2. How do I choose between N-Channel and P-Channel MOSFETs? What are the differences?
N-Channel: preferred for low-side switching and high-frequency rectification. P-Channel: suited for high-side power switches, reverse current blocking, and battery protection. The core differences are conduction polarity, driving method, and application topology. Choose based on your circuit topology.
3. Do your products support automotive / industrial-grade standards?
All products come standard with industrial-grade rating and excellent stability; selected series achieve automotive-grade rating, capable of withstanding harsh conditions including extreme temperatures, avalanche withstand voltage, and high heat dissipation. They are suitable for new energy vehicles, industrial control equipment, automotive BMS, AI server power supplies, industrial test equipment, and more.
4. What are the characteristics of P-Channel MOSFETs?
Simple driving and high input impedance as voltage-controlled devices; when used as high-side switches, the gate can be driven directly by logic levels, simplifying circuit design.

3. Selection Parameters & Technology Differences
1. Key MOSFET selection parameters?
Rated voltage Vds, rated current Id, on-resistance Rds(on), gate charge Qg, switching frequency, package size, avalanche capability, and thermal performance — combined with circuit voltage, load current, drive voltage, and switching frequency, selection can be completed.
2. Advantages of ultra-low on-resistance Rds(on)?

3. Difference between Super Junction MOSFETs and conventional MOSFETs?
In conventional high-voltage MOSFETs, on-resistance grows cubically as voltage rating increases. Super Junction MOSFETs use alternating N/P pillars in the drift region, boosting the doping concentration by 5~10 times while maintaining high voltage capability, significantly reducing on-resistance while delivering fast switching and low losses. Note: GOFORD GC-series models are Super Junction MOSFETs; the equivalent from Infineon is CoolMOS™.
4. Features of GT-series models?
Using Split Gate Trench (SGT) technology, the gate is split into a shield electrode and a control gate, reducing Miller capacitance and switching losses; ideal for high-frequency applications such as fast charging. Infineon's equivalent process is named OptiMOS™.
5. Differences and selection of TO-220 / TO-263 / TO-247?
TO-220: through-hole package, suitable for manual soldering and high-power applications; TO-263: surface-mount package, suitable for SMT automated production lines; TO-247: mostly used in ultra-high-power applications. Choose based on the soldering method and PCB layout.
