概述
Description
SMV1231-040LF is a RoHS-compliant Schottky barrier rectifier diode (SMD, lead-free) used for low-loss, fast rectification in switching power supplies and protection circuits. It features a 40 V reverse-voltage rating and a forward-current rating around 1 A (exact values in the datasheet). The LF suffix denotes lead-free construction, and it comes in a compact SMD package (SOD‑123/SOD‑123FL family). For precise parameters (IF(AV), VF, IR, cycle ratings, and packaging), consult the manufacturer’s datasheet.
Features
Here are the key features of SMV1231-040LF:
- Surface-mount Schottky barrier rectifier
- VRRM: 40 V (reverse voltage)
- IF(AV): typically 1 A (average forward current)
- Very low forward voltage drop (high efficiency; reduced power loss)
- Fast switching with no reverse recovery
- Pb-free, RoHS compliant
- Plastic molded package (SMD, compact footprint)
- Wide operating temperature range (typical -55°C to 125°C)
- Robust surge/high-current capability for short peaks
Note: Exact values (forward voltage, surge specs) can vary slightly by lot; consult the datasheet for precise parameters.
