FM4007 是 LGE(鲁光)推出的一款独立式通用整流二极管,采用 SOD-123FL 小封装,面向中高压整流和保护应用。该器件在 1A 工作电流条件下正向压降约为 1.1V,反向耐压高达 1000V,反向漏电流在 1kV 时典型值仅 5μA,具有良好的高压耐受能力与低漏电特性,适合要求体积小、耐压高的电源与保护电路。
FM4007 在常见工作点下表现稳定,1A 直流整流时正向压降约 1.1V,能在中等功率密度场合提供可靠整流。1000V 的反向耐压和极低的漏电流(5μA@1kV)使其可用于高压整流链、反向保护及高压检测电路。30A 的非重复峰值浪涌电流保证了在浪涌过载或瞬态冲击时的短时存活能力(请在设计时关注浪涌时长与热耗散)。
SOD-123FL 为小型表面贴装封装,适合高密度 PCB 设计和自动化贴装。尽管封装体积小,但在正常自然冷却条件下可承受 1A 持续整流。设计散热时建议:
在需要更低正向压降或更高峰值浪涌能力的场合,可考虑肖特基或更大封装的高浪涌二极管;若需更高的工作电流,可采用 TO-xxx 或 DO-214 等散热更好的封装。选型时需综合考虑耐压、正向压降、漏电流及热管理方案。
FM4007 提供标准卷带包装,适用于自动贴装生产线。订购时请明确所需的最小起订量、包装方式与相关质量认证(如有),并与供应商确认器件的批次与测试报告以确保一致性与稳定性。
总结:FM4007(LGE 鲁光)是一款面向中高压整流和保护应用的通用二极管,凭借 1kV 耐压、低漏电和小型 SOD-123FL 封装,适合体积受限且需高压耐受的电子系统。根据具体应用场景合理设计散热与 PCB 布局,可获得可靠而稳定的长期工作表现。

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.
