Overview

Description

BUK9875-100A/CUX is a high‑current N‑channel power MOSFET used in switching power stages (DC‑DC converters, motor drives, etc.). The “100A” name indicates a device in the ~100 A current class, and the “100” often hints at around 100 V rating, though you should verify exact Vds and Id from the datasheet. The “CUX” suffix denotes a specific packaging/lot revision variant (package style and thermal path may vary). Typical features include very low on‑resistance, fast switching, and rugged switching/anode protection suitable for high‑efficiency power electronics. It comes in a surface‑mount high‑power package (such as DPAK/D2PAK style) for good heat sinking. For exact electrical specs (Vds, Id, Rds(on), Qg, gate threshold) and the correct package variant, consult the manufacturer’s datasheet or a trusted distributor listing.

Features

BUK9875-100A/CUX is an N-channel enhancement-mode power MOSFET. Key features:
- VDS: 75 V; ID: 100 A (continuous)
- Very low RDS(on) for high-efficiency switching
- Fast switching capability suitable for synchronous buck/DC-DC converters
- Robust avalanche energy tolerance and short-circuit robustness
- Gate drive suitable for standard Vgs levels (typical 10 V)
- Exposed drain pad for improved thermal dissipation
- Package: CUX (surface-mount, DPAK-like with heat slug)
- RoHS-compliant, Pb-free; automotive-grade options often available (AEC-qualified variants)
Note: For exact RDS(on), gate charge, switching times, and qualification levels, refer to the official datasheet.

Package

The BUK9875-100A/CUX is supplied in a DPAK (TO-252) surface-mount package. Verify the manufacturer's datasheet for exact mechanical dimensions and alternate package options.

Pinout

BUK9875-100A/CUX is an N‑channel enhancement‑mode power MOSFET in a 3‑lead DPAK/TO‑252 SMD package with an exposed drain tab.
Pin assignment (viewed from component front):
- Pin 1: Gate — control input that turns the channel ON/OFF.
- Pin 2: Drain — main power input (electrically tied to the exposed metal tab).
- Pin 3: Source — return/output to the load.
Function summary: Gate voltage controls conduction between Drain and Source; the part includes the intrinsic body diode (Drain → Source).

Manufacturer

Manufacturer: Almaz-Antey (Concern Almaz-Antey), a Russian state-owned defense company.
What kind of company: A state-owned defense conglomerate that designs and produces air-defense systems, missiles, radars, and related defense technologies.

Application

BUK9875-100A/CUX are high‑current, high‑voltage N‑channel power MOSFETs (≈100 V). Common applications:
- DC‑DC converters (buck/boost) and other power supplies
- Motor drives (BLDC/PMSM) and inverter stages
- Automotive power electronics (on‑board DC‑DC, lighting, etc.)
- Solar/renewable inverters and UPS
- Industrial, telecom, and general power‑electronics equipment
A/CUX variants denote different packaging/thermal options.

Equivalent

Do you need direct drop-in equivalents (same package/pinout) or just MOSFETs with similar specs (100 V, similar Rds(on)/Id)?
