Übersicht

Description

BUK7Y21-40EX is a power MOSFET (N-channel) used for switching power stages. It’s designed for high-current, high-voltage applications such as DC‑DC converters, motor drives, and automotive electronics. The device is offered in a surface‑mount power package (for example, D²PAK/TO‑263 style) with standard gate, drain, and source terminals and a drain tab for heat sinking. Typical advantages include low on-resistance, fast switching, and good avalanche energy handling, enabling compact, efficient power designs. Exact specs (Vds, Id, Rds(on), Qg), package options, and thermal characteristics vary by revision and lot. Always consult the latest manufacturer datasheet and cross‑reference the exact suffix (40EX) to ensure correct electrical and mechanical compatibility for your design or replacement.

Features

I don’t have the exact datasheet for BUK7Y21-40EX without the manufacturer. Please share the vendor or a link and I’ll pull precise specs. In the meantime, typical features for devices in this family (high-voltage, fast-switching power switches) include:
- High blocking voltage (roughly in the 700 V class)
- Significant continuous current rating (tens of amperes)
- Low on-state resistance or low conduction loss
- Fast switching performance (low input/output capacitances, fast rise/fall times)
- Ruggedness (avalanche energy capability, protection against short-circuit/SOA limits)
- Thermal robustness for power electronics
- Available in power-packaging suitable for SMPS/motor-drive use (e.g., D²PAK/TO-263 or similar)
For exact numbers (Vds, Id, Rds(on), switching times, packaging), please provide the datasheet or vendor.

Package

The BUK7Y21-40EX is an N‑channel MOSFET supplied in a DPAK (TO‑252) surface‑mount package.

Pinout

BUK7Y21-40EX is an N-channel power MOSFET with three electrical terminals: Gate (G), Drain (D) and Source (S). It is commonly supplied in a DPAK/TO‑252 style package where the package has three lead pins (G, D, S) plus a large metal tab/heat pad that is electrically connected to the Drain (so some counts list 4 physical pads).

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (formerly the standard products division of NXP) that designs and produces discrete and MOSFET power devices, diodes, transistors and logic ICs—specializing in high-volume, energy-efficient components for automotive, industrial and consumer electronics.

Application

BUK7Y21-40EX is a high-voltage, high-current N-channel MOSFET for switching in power electronics. Typical applications include:
- Switch-mode power supplies (AC-DC and DC-DC)
- Motor drives and PWM control
- Solar/grid/inverters and other high-voltage inverters
- Uninterruptible power supplies (UPS)
- Automotive and industrial power-management systems
Concise and suitable for general power-switching uses.

Equivalent

I don’t have that part in my local data. Please share the BUK7Y21-40EX datasheet or its key specs (VDS, ID, RDS(on), VGS, package) or allow me to look it up online — with that I can list close equivalents (same voltage/current class, RDS(on), and package).
