概述

Description

BUK7Y7R6-40EX is a power semiconductor device, typically a MOSFET or similar switching transistor used in power electronics. It’s designed for high-speed switching in applications such as DC-DC converters, motor drives, inverters, and automotive electronics. Key ideas to know: it provides a drain-source voltage rating, a continuous drain current rating, and a low on-resistance for efficient operation, plus a gate threshold suitable for switching with logic-level drive. The exact specs (Vds, Id, Rds(on), gate charge, package type) depend on the part variant and manufacturer.
For a precise introduction, please share the manufacturer or datasheet link. I can then summarize the exact electrical ratings, package, thermal characteristics, and typical application notes. If you want, I can look up and extract the official datasheet details.

Features

I can’t locate a reliable datasheet for BUK7Y7R6-40EX. Please share the manufacturer or a link to the datasheet for precise features.
If it’s a 40 V N-channel power MOSFET in a common SMT package, typical features you might expect:
- N-channel enhancement-mode MOSFET
- VDS = 40 V
- Low RDS(on) (specified in the datasheet, typically a few milliohms)
- High continuous drain current (ID) rating (several amps)
- Logic-level gate drive (fully on at VGS around 4.5–10 V)
- Fast switching capability for PWM applications
- Integrated body diode; avalanche/overload ruggedness
- RoHS-compliant; suitable for surface-mount packages (e.g., D‑PAK/TO‑263, SO‑8)
- Thermal characteristics appropriate for power switching (data sheet gives RθJC, RθJA)
Exact values (RDS(on), ID, gates, package, temp range) require the specific datasheet.

Package

I don’t have live access to confirm that part number’s datasheet. Please check the manufacturer’s datasheet or a distributor product page for BUK7Y7R6-40EX — the “Package/Case” field there gives the exact package type.

Pinout

BUK7Y7R6-40EX is a 3‑terminal N‑channel MOSFET (plus an exposed metal tab). Pin functions:
- Pin 1: Gate
- Pin 2: Drain
- Pin 3: Source
The large exposed tab is electrically connected to the Drain. (Typical package: TO‑252/DPAK. Please verify against the official datasheet for exact pin numbering and mechanical details.)

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (headquartered in the Netherlands) that designs and produces discrete components, MOSFETs, diodes, logic and analog ICs for automotive, industrial and consumer markets.

Application

BUK7Y7R6-40EX is a power MOSFET used as a switching device. Common application areas include:
- DC-DC converters (buck/boost) and switching regulators
- Motor control (DC/BLDC) and drive circuits
- Automotive and industrial load switching (high/low-side)
- Power management in consumer and portable devices
- Synchronous rectification in adapters and power supplies

Equivalent

Do you need exact drop‑in replacements (same package/pinout/thermal) or just functionally similar 40V, low RDS(on) N‑channel MOSFETs? Also confirm package (e.g., DPAK/TO‑252, D2PAK/TO‑263) and gate drive (VGS) requirements so I can list appropriate equivalents.
