FR107W是FOSAN(富信)推出的快恢复/高效率二极管,核心参数围绕「高压耐量、快恢复特性、低导通损耗」设计,精准匹配中高压小功率电源场景:
快恢复提升高频效率
500ns的反向恢复时间,可大幅减少开关过程中的反向恢复损耗——普通整流管在高频(如几十kHz)下会因恢复慢产生额外发热,而FR107W能适配开关电源(SMPS)、逆变器等高频电路,避免效率下降。
低VF降低导通损耗
1A电流下仅1.3V的正向压降,相比同参数竞品(部分FR107的Vf达1.5V以上),导通损耗可降低约15%。这一特性对LED驱动、便携充电器等「效率敏感」场景尤为重要,能减少散热片需求,简化电路设计。
高压耐量覆盖宽场景
1000V的反向耐压,可直接应用于AC110V/220V输入的电源电路(整流后反向电压峰值约310V/620V,远低于1000V安全裕量),避免反向击穿风险。
宽结温保障可靠性
-65℃~+150℃的工作结温,覆盖了工业控制(如车间高温环境)、汽车电子(发动机舱120℃以上)、户外设备(低温严寒)等严苛场景,长期工作失效率低。
FR107W采用SOD-123FL表面贴装封装,兼具「小型化」与「可靠性」:
FR107W的参数特性使其成为以下场景的优选器件:
FR107W凭借「快恢复、低损耗、高压宽温」的综合优势,成为小功率高压电源电路的核心器件,覆盖消费电子、工业控制、汽车电子等多领域,其小型化封装也契合了现代电子设备的轻薄化趋势。

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.
