FR107L是Hottech(合科泰)推出的一款独立式快恢复/高效率二极管,针对中小功率高频整流场景设计,平衡了正向压降、反向耐压与反向恢复速度,兼具小型化封装与可靠性能,适用于消费电子、电源适配器、LED驱动等多个领域。
FR107L属于快恢复二极管类别,区别于普通硅整流管(反向恢复时间通常达数十微秒),其500ns的恢复时间可有效降低高频开关过程中的损耗与电磁干扰(EMI);同时区别于超快恢复二极管(恢复时间<100ns),在成本与性能之间实现了更优平衡,适合频率范围在数十kHz的常规开关应用。作为独立式封装器件,可灵活应用于整流电路、续流电路等场景,无需依赖集成桥堆结构。
FR107L的电气参数精准匹配中小功率应用需求,核心参数如下:
正向压降(Vf)为1.3V@1A:在额定整流电流1A下,正向压降处于合理区间——虽略高于普通硅整流管(如1N4007约0.7V@1A),但因快恢复工艺的扩散设计,可在保证恢复速度的同时,将正向损耗控制在可接受范围,适合对效率有一定要求的场景。
FR107L采用SOD-123FL表面贴装封装,具备以下特点:
FR107L的参数特性使其适用于多种高频整流与续流场景:
FR107L由国内知名半导体厂商Hottech(合科泰)生产,该厂商专注于功率器件研发多年,产品符合RoHS、REACH等环保标准,且经过可靠性测试(如温度循环、湿热测试),可满足消费级与工业级应用的品质要求,为电路设计提供稳定可靠的器件选择。
FR107L作为一款性价比突出的快恢复二极管,在1A电流、1kV耐压下实现了500ns的反向恢复速度,正向压降合理,封装小巧灵活,适用于多种中小功率高频应用场景,是电源设计中替代普通整流管、平衡成本与性能的理想选择。

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.
