Description
BUK7Y21-40EX is a high‑power N‑channel IGBT (discrete switch) in the BUK7Y family, used for fast switching in power-electronic converters. It’s typically employed in motor drives, inverters, and switch-mode power supplies.
Key points to know:
- Voltage and current ratings (Vces, Ic) from the datasheet
- Vce(sat) and switching speeds (td(on)/td(off))
- Gate drive requirements (Vge, logic-level or standard drive)
- Thermal characteristics (RthJA, mounting method)
- Built‑in diode or anti-parallel diode behavior
- Package type (TO‑220, D²PAK, etc.) and mounting/heat sinking
Exact specs vary by vendor and package; please share the vendor or a datasheet link for precise values. I can summarize the exact electrical ratings, safe-operating-area, and thermal data once I have the official datasheet.

Equivalent
I can’t reliably list equivalents without the MOSFET specs. BUK7Y21-40EX is an N-channel MOSFET; please provide: Vds, Id, Rds(on) (max), package, and whether a logic-level gate is required. With those I’ll give precise cross references from major brands (Infineon, ST, Rohm, Vishay) and distributor part numbers.
Features
BUK7Y21-40EX is a 40 V N-channel enhancement-mode power MOSFET. Key features:
- Vds: 40 V
- Id: 21 A (continuous)
- Very low Rds(on) (milliohm range) for high-efficiency conduction
- Logic-level gate drive (fully on at typical 4.5–5 V)
- Fast switching with low gate charge
- Robust protection: avalanche energy rating and diode characteristics suitable for switching
- Wide use in DC-DC converters, motor drives, high-side/low-side switches
- RoHS-compliant, lead-free
- Package: surface-mount power package (D²PAK/TO-252 style) with good thermal performance
- Operating temp: up to ~150°C junction
Note: exact Rds(on), gate threshold, and packaging can vary by lot; consult the datasheet for precise numbers.
