概述

Description

BUK9M52-40EX is an export variant of Russia’s Buk family mobile air-defense system. It defends units and key facilities from aircraft, helicopters, drones, and some missiles at medium range. The system is a self-propelled combination of a missile launcher, a radar/target-acquisition unit, and a fire-control/command vehicle, designed for rapid detection, tracking, and engagement of multiple targets, often operating in a networked air-defense layout with other units. The 9M52 family missiles provide fast interception and can be launched in salvos to defeat agile threats. The “-40EX” suffix denotes an export configuration tailored for international customers, sometimes with equipment variations or limitations compared with domestic versions. Widely exported and deployed in several countries, it is used to provide brigade- or facility-level air-defense coverage.

Features

BUK9M52-40EX is a mobile, medium‑range air defense missile for the Buk family. Key features:
- Mobile TEL-based system with all‑weather, day/night operation.
- Two‑stage solid-propellant motor (booster and sustainer).
- Guidance: semi‑active radar homing in terminal phase with ground-based illumination and midcourse command updates.
- Warhead: high‑explosive fragmentation with proximity fuse (option for contact detonation).
- Engagement envelope targeting aircraft, helicopters and some missiles at medium altitude; supports multi‑target engagement.
- ECCM‑resistant avionics and integrated fire-control linkage with Buk radar/comms.
- Export variant (40EX) offers extended performance while remaining compatible with standard Buk fire‑control and radar systems.
Note: exact range/altitude figures vary by configuration and mission profile.

Package

D²PAK (TO-263) surface-mount package with an exposed pad (three leads plus tab).

Pinout

Pin count: 8 pins (with an exposed pad on the package).
Function: Dual N-channel enhancement-mode power MOSFET in one package, typically used as a high-side/low-side pair in a half-bridge or switching power stage.

Manufacturer

Manufacturer: Almaz-Antey (Almaz-Antey Air and Space Defence Corporation).
What kind of company: A large Russian state-owned defense conglomerate that designs, develops, and manufactures air-defense systems, missiles, radars, and related military equipment.

Application

BUK9M52-40EX is a high-voltage, high-current N-channel power MOSFET. Common applications:
- Offline and DC-DC switch-mode power supplies (PFC/LLC)
- Motor drives (BLDC/PMSM)
- Inverters for solar and battery systems, UPS/telecom power
- Automotive and industrial power electronics (DC-DC, chargers)

Equivalent

I can’t provide exact equivalents without the device specs. BUK9M52-40EX is a high-power IGBT/diode device; cross-references depend on Vces, Ic, switching speed, and package. Please share the datasheet or key ratings (e.g., Vces, Ic, packaging). With that, I can give precise equivalents from Infineon, ST, ON Semiconductor, Vishay, TI, etc.
