概述

Description

STD5NM50T4 is an STMicroelectronics N-channel enhancement MOSFET in the high‑voltage STD5NM50 family. It’s intended for switching power applications such as offline SMPS, motor drives, and DC–DC converters.
Key points:
- High-voltage N‑channel trench MOSFET suitable for wide voltage rails (typical class around 500 V).
- Built for efficient switching with a rugged body diode and reliable on/off performance.
- Used in configurations like half‑bridge/full‑bridge with appropriate gate drive and protection.
Notes:
- Exact ratings (Vds, Id, Rds(on), Qg, packaging, thermal specs) vary by device variant; consult the current ST datasheet for STD5NM50T4 for precise numbers.
- Typical packaging options and gate-drive requirements depend on the specific package (D²PAK, TO‑220, etc.) and application.
If you need precise Electrical Characteristics or a recommended circuit, I can summarize the datasheet once you share the exact variant or a link.

Features

Equivalent

I don’t have the full STD5NM50T4 datasheet here, but equivalents are other 500 V N‑channel power MOSFETs with matching VDS, ID, RDS(on), Qg and package. Common substitutes to consider: IRF830 / IRF840 (Vishay/IR), STW5NM50 / MTP5N50 (STMicro), FDPF5N50 (Fairchild/Vishay). Always verify electrical ratings, thermal limits and pinout against the original before substituting.
