Descripción general

Description

BUK7Y3R5-40HX is a power semiconductor part number used for switching power electronics (typically a MOSFET or IGBT). The exact electricals depend on the vendor, as the BUK prefix is used by multiple manufacturers.
What it typically represents
- A high-current, fast-switching transistor for power conversion, motor drives, lighting drives, and inverters.
- Used as the main switching element in DC-DC converters and AC motor drives.
Key specs to check (from the vendor datasheet)
- Vds (drain–source voltage) and Id (continuous current)
- Rds(on) (for MOSFETs) or Vce(sat) (for IGBTs)
- Gate drive requirements (Vgs for MOSFETs or gate threshold)
- Total gate charge and switching times
- Package type and thermal resistance
How to use
- Verify the exact part variant with the supplier’s datasheet.
- Ensure your gate drive voltage, heat sinking, and PCB layout meet the device’s needs.
If you share the vendor or a link to the datasheet, I can summarize the exact specs.

Features

I don’t have the datasheet on hand, but BUK7Y3R5-40HX is a 40 V N-channel power MOSFET. Expected key features (as per the naming):
- Vds: 40 V
- Id: about 7 A continuous
- Rds(on): around 3.5 mΩ (max)
- Type: N-channel enhancement-mode
- Switching: fast switching performance, suitable for high-efficiency power conversion
- Protection: avalanche ruggedness, body diode
- Packaging: surface-mount power package (DPAK/TO-252‑like) – check exact variant
- Compliance: RoHS/Pb-free
For precise electrical specs (exact Id rating, Rds(on) tolerance, Vgs(th), Qg, packaging, and required drive voltage), please share the datasheet or a link and I’ll summarize accurately.

Package

I don’t have the package type for BUK7Y3R5-40HX in my available data. Please provide the manufacturer or a datasheet link, or allow me to look it up online — then I can give the exact package (e.g., TO‑220, DPAK, etc.).

Pinout

BUK7Y3R5-40HX is a 3-pin N‑channel enhancement‑mode power MOSFET (plus a metal tab/backside). Pin functions:
- Pin 1: Gate — control terminal (voltage input).
- Pin 2: Drain — main current input; usually connected to the large tab/backside.
- Pin 3: Source — current output/return (reference to source).
Note: the metal tab/backside is electrically connected to the Drain.

Manufacturer

Manufacturer: Infineon Technologies AG.
What kind of company: Infineon is a German multinational semiconductor company that designs and manufactures power semiconductors (MOSFETs, IGBTs), microcontrollers, sensors and security chips for automotive, industrial, and consumer electronics applications.

Application

Common application areas for BUK7Y3R5-40HX (a 40V N-channel MOSFET) include:
- Power-management circuits: DC-DC converters (buck/boost) and synchronous rectification
- Load switches and high-side/low-side switches in PMICs
- Motor/actuator drivers (DC and BLDC)
- Automotive and industrial power electronics and battery-powered devices
- Solar charge controllers and small inverters
Note: Check the datasheet for exact electrical specs and recommended operating conditions.

Equivalent

I don’t have live web access—please provide the BUK7Y3R5-40HX manufacturer or its datasheet (VDS, RDS(on), ID, package, gate charge). With those key specs I can list accurate equivalent MOSFETs.
