Visão Geral
Description
BUK7Y3R5-40HX is a high-voltage, high-current MOSFET in the BUK family, used for switching in power electronics. It’s typically employed in offline power supplies, DC-DC converters, motor drives, and other PWM switching applications. Key specs you’ll want from the official datasheet include VDS (drain–source voltage), ID (continuous drain current), RDS(on) (on-resistance), gate threshold and drive voltage, switching times, and the exact package/pinout. The “40HX” suffix usually denotes a specific voltage/power/packaging variant within the line. Because marking codes can vary by lot and manufacturer, verify exact details from the manufacturer’s datasheet or a trusted distributor cross-reference. If you share the manufacturer or a link, I can pull the precise specs and summarize them.
Equivalent
I can provide cross references, but I need the exact datasheet or package. BUK7Y3R5-40HX is a 40V N‑channel MOSFET (Rds(on) ≈ 3.5 mΩ). Please confirm the package (e.g., D2PAK/TO-263) and preferred vendors (Infineon/ON Semi/ST/Vishay), or allow me to look up the latest cross parts.
Features
BUK7Y3R5-40HX is a 40 V N‑channel MOSFET. Likely features include:
- N‑channel enhancement mode, Vds = 40 V
- Very low Rds(on) in the few milliohms (typ around 3.5 mΩ; max a few mΩ)
- High continuous current capability (tens of amps, depending on package and cooling)
- Logic‑level gate drive (Vgs(th) ~1–2 V; suitable for 4.5–10 V drive)
- Fast switching with low gate charge
- Robust body diode with good reverse recovery; avalanche energy ruggedness
- Power/TO‑like package (e.g., D2PAK/DPAK or similar) with good thermal performance
- Suitable for high‑efficiency DC‑DC converters, motor drives, and other high‑current switching applications
Note: exact values (Rds(on), Id, package) depend on the specific manufacturer. Please consult the datasheet for precise numbers.
