FR107L 快恢复二极管产品概述

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。

一、产品核心身份与技术定位

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。

二、关键电气参数解析

FR107L的电气参数精准匹配中小功率应用需求,核心参数如下:

1. 正向特性

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。

2. 反向耐压与漏电流

  • 直流反向耐压(Vr)达1kV:可稳定承受1000V直流反向电压,覆盖市电(220V)相关应用的安全余量,也可满足部分中等高压场景(如小型逆变电路输出)的耐压需求。
  • 反向漏电流(Ir)仅5μA:反向阻断时漏电流极小,说明器件反向特性优异,可降低待机损耗,提升电路可靠性。

3. 恢复速度与电流能力

  • 反向恢复时间(Trr)为500ns:这是快恢复二极管的核心指标,比普通整流管快数十倍,可有效减少开关过程中二极管的反向恢复损耗,避免因恢复过慢导致的尖峰电压与EMI问题。
  • 额定整流电流(IF)为1A:持续工作电流不超过1A,峰值电流(IFSM)可参考厂商 datasheet(通常为[email protected]),满足中小功率设备的电流需求。

三、封装与物理特性

FR107L采用SOD-123FL表面贴装封装,具备以下特点:

  • 尺寸小巧:符合表面贴装器件的高密度布局要求,适合小型化产品(如便携电源、LED球泡灯)的PCB设计。
  • 自动化适配:表面贴装封装便于自动化生产,可降低人工成本,提升生产效率。
  • 散热设计:虽封装尺寸小,但1A电流下的热阻可满足中小功率应用的散热需求(需配合合理的PCB铜箔设计),无需额外散热片即可稳定工作。

四、典型应用场景

FR107L的参数特性使其适用于多种高频整流与续流场景:

  1. 开关电源次级整流:如手机充电器、笔记本电源适配器的次级整流电路,利用快恢复特性降低开关损耗,提升电源效率。
  2. LED驱动电源:LED驱动电路的整流部分,1A电流可覆盖多个LED串联的功率需求(如10-20W LED灯具),1kV耐压可应对浪涌电压。
  3. 小型逆变电路:如太阳能微型逆变器、车载逆变电源的输出整流,满足低压逆变后的电压等级需求。
  4. 电机驱动续流:小型直流电机、步进电机的续流二极管,快恢复可减少电机关断时的反向尖峰电压,保护电路器件。
  5. 消费电子电源:如机顶盒、路由器的电源整流电路,平衡成本与性能,提升设备可靠性。

五、品牌与品质保障

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。

总结

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。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
