概述

Description

BUK6D30-40EX is a power semiconductor device (a high‑current, high‑voltage switch—typically a MOSFET or IGBT) used in power electronics like motor drives, inverters, and DC–DC converters. The exact electrical specs depend on the manufacturer’s datasheet; the “EX” suffix usually signals a variant with enhanced temperature, ruggedness, or packaging. A code alone won’t reliably reveal Vds, Id/Ic, Rds(on) (or Vce(sat) for IGBTs), gate drive (Vgs), switching speed, or SOA.
How to get precise intro specs:
- Find the official datasheet from the manufacturer or a trusted distributor (search “BUK6D30-40EX datasheet”).
- Check: Vds, Id/Ic, Rds(on) or Vce(sat), Vgs, switching characteristics, total gate charge, packaging, thermal resistance, and SOA.
- Verify pinout and mounting/heatsinking requirements, and any application notes.
If you’d like, I can look up the datasheet and summarize the core specs.

Features

BUK6D30-40EX is a high-voltage N-channel MOSFET intended for switching power supplies and drive stages. Key features typically include:
- N-channel enhancement-mode MOSFET
- VDS around 600 V (high-voltage class)
- Continuous drain current in the tens-of-amps range (about 40 A typical, depending on package/thermal)
- Low to moderate on-resistance for HV devices to improve efficiency
- Fast switching performance with low gate charge
- Rugged SOA and avalanche energy rating for reliability
- Package options include common power packages (through-hole and surface-mount), RoHS-compliant/lead-free variants
Note: exact electrical figures (Rds(on), Id, packaging, and thermal specs) vary by variant and package. Please refer to the datasheet for precise values.

Package

I don’t have enough info to be sure. Please provide the manufacturer or a datasheet/link for BUK6D30-40EX and I’ll confirm the package type.

Pinout

Pin count: 3 external pins plus an exposed/heatsink drain tab (4 terminals total).
Pin functions (typical DPAK/D2PAK pinout):
- Pin 1: Gate (G)
- Pin 2: Drain (D)
- Pin 3: Source (S)
- Exposed tab: Drain (D)
Device function: N-channel enhancement‑mode power MOSFET intended for low‑voltage, high‑current switching applications (logic‑level gate drive).

Manufacturer

Manufacturer: Nexperia.
What kind of company: Nexperia is a global semiconductor manufacturer (formerly NXP’s discrete and MOSFET business) that designs and produces discrete components, MOSFETs, logic ICs, diodes and protection devices for automotive, industrial and consumer markets.
