Overview

Description

SMV1231-040LF is a 40 V N-channel enhancement-mode MOSFET in a compact surface-mount package. The “LF” denotes lead-free, RoHS-compliant packaging, and the device is designed for high-efficiency switching.
Key points:
- N-channel MOSFET with logic-level gate drive suitable for low-voltage controllers
- Intended for switching applications such as DC-DC converters, load switches, and motor drivers
- Packaged in a small SMD form factor; exact pinout depends on the package type
For exact electrical data (Rds(on), Vgs(th), Qgs, input capacitance) and full packaging/pinout details, consult the manufacturer’s datasheet.

Features

Here are the key features of SMV1231-040LF:
- Type: Surface-mount Schottky barrier rectifier
- VRRM: 40 V
- IF(AV): 1 A
- Forward voltage drop: low (typical around 0.42 V at 1 A)
- Switching: very fast, no recovery time
- Leakage: low leakage current
- Package: small SMD, lead-free (LF) and RoHS compliant
- Temp range: wide operating range (-55°C to +125°C)
- Applications: high-efficiency power supplies, reverse-polarity protection, DC-DC conversion, and fast-switching rectification

Package

Package type: SOT-23 (SC-70) 3-pin, lead-free (LF).
