Overview

Description

BUK7Y12-40EX is a high-voltage, high-current power semiconductor device used for switching in power electronics. It is intended for applications like motor drives, inverters, switch-mode power supplies, and automotive control units. The exact device type (MOSFET or IGBT) depends on the variant; confirm from the datasheet.
Key points to know:
- Voltage and current ratings (Vds/Vce, Id) and how they fit your load.
- On-state characteristics (Rds(on) for MOSFETs or Vce(sat) for IGBTs) and switching speed.
- Gate drive requirements (voltage level, drive current, and voltage isolation).
- Packaging and thermal considerations (pinout, mounting, heat sinking).
- Safe operating area and protection features.
For precise specs, consult the manufacturer’s datasheet or a trusted distributor listing. If you share a link or confirm the manufacturer, I can summarize the exact ratings, pinout, and typical application recommendations.

Features

BUK7Y12-40EX is a N-channel enhancement MOSFET for switch-mode power supplies, motor drives, and load switching. Key features typically include:
- Vds: 40 V
- Id: ~7 A continuous current
- Low on-resistance for high efficiency
- Logic-level gate drive (works with 4.5 V/5 V logic)
- Fast switching with low gate charge
- Robust body diode and avalanche-energy capability
- Surface-mount package (EX variant); RoHS-compliant
- Wide operating temperature range (EX/grade variants offer extended temps for automotive/industrial use)
Note: exact specs (Rds(on), temp range, package variant) can vary by revision; please consult the latest datasheet for precise numbers.

Package

The BUK7Y12-40EX is supplied in a DPAK (TO-252) surface-mount package; the "X" typically denotes tape-and-reel packaging.

Pinout

BUK7Y12-40EX is an N‑channel enhancement MOSFET in a 3‑lead SMD package with an exposed metal tab. Pin count and functions:
- Pin 1: Gate (G) — control terminal
- Pin 2: Drain (D) — main current inlet (also connected to the exposed heatsink tab)
- Pin 3: Source (S) — current outlet / reference
So electrically it has three terminals (G, D, S); the metal tab is tied to Drain for thermal/current carrying.

Manufacturer

The BUK7Y12-40EX is manufactured by Nexperia. Nexperia is a global semiconductor company (spun out of NXP) that specializes in discrete components and power MOSFETs, logic and analog ICs used in automotive, industrial and consumer electronics.

Application

BUK7Y12-40EX is a high-voltage, high-current IGBT used in medium/high-power switching. Typical applications include: motor drives and speed controllers (AC motors), solar/wind power inverters and energy-storage DC-DC stages, uninterruptible power supplies (UPS) and industrial power supplies, welding and induction heating equipment, and other switch-mode power converters needing efficient high-voltage switching.
