FMAF407 是乐山无线电(LRC)推出的一款通用独立式整流二极管,采用 SMA-FL 表面贴装封装。该器件设计用于中高压整流场合,标称正向压降典型值为 1.1V,直流反向耐压达 1kV,连续整流电流 1A,适合开关电源一次侧、高压整流、工业电源及稳压保护等应用场景。
SMA-FL 为小型表面贴装封装,便于自动化贴装与回流焊工艺。由于 Vf 在 1A 时约 1.1V,器件在满载时功耗约为 P = Vf × If ≈ 1.1W,需考虑印制板铜箔面积和导热路径以降低结温。建议:
FMAF407 在 1kV 的高耐压能力与 1A 的整流电流下,兼具低正向压降与较低漏电的特点,适合多种中高压整流及保护用途。合理的版面热设计与浪涌保护是确保长期可靠运行的关键。如需更详细的电气特性曲线、封装图或焊接说明,建议向 LRC 索取完整数据手册进行最终设计验证。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
