K110 产品概述

一、产品简介

K110 是 GOODWORK(固得沃克)推出的一款独立式肖特基整流二极管,面向中小功率整流与保护应用。该器件采用 SOD-123FL 小外形封装,设计用于宽温度范围工作(结温 -65℃ 至 +150℃),在 1A 直流整流电流条件下表现稳定,兼顾体积紧凑与热性能要求,适合空间受限且需快速恢复或低压降整流的电路。

二、主要电气参数

  • 二极管类型:肖特基二极管(独立式)
  • 正向压降(Vf):850 mV @ IF = 1 A
  • 直流整流电流(IF):1 A
  • 非重复峰值浪涌电流(Ifsm):30 A
  • 直流反向耐压(Vr):100 V
  • 反向电流(Ir):200 µA(典型或最大值,请参见详细数据表)
  • 工作结温范围:-65℃ ~ +150℃
  • 封装:SOD-123FL

以上参数为器件选型的关键指标,具体条件(如测试温度、测量协议)请以厂方数据表为准。

三、产品特点

  • 可靠的中功率整流能力:1A 连续整流电流配合高达 30A 的浪涌能力,能抵御短时冲击电流。
  • 宽温度适应性:结温范围覆盖工业级与更严苛环境,适合温变环境下长期工作。
  • 小巧封装:SOD-123FL 提供紧凑的占板面积,利于高密度 PCB 布局与便携设备设计。
  • 良好的反向耐压能力:100V 的耐压等级适配多数 12V/24V 系统以及中等电压线路的整流与保护需求。

四、典型应用场景

  • 开关电源输出整流与二次侧保护
  • 反向电池保护、方向保护电路
  • 功率管理与降压模块的输出整流
  • 功率二极管替换、快速恢复整流场合(需权衡 Vf 与恢复特性)
  • 车载电子、通信设备、工业控制板等受限空间的中低功率电路

五、封装与热管理

SOD-123FL 封装兼顾小体积与可接受的散热能力,但在 1A 连续工作且高环境温度下,封装热阻会影响结温上升。建议在 PCB 布局时:

  • 在二极管焊盘周围增加铜箔扩展以改善散热;
  • 为连续高电流或高温应用考虑强制对流或热沉方案;
  • 在设计时采用器件结温与环境温度的热裕量估算,必要时进行 derating(降额)处理。

六、可靠性与工作条件

  • 额定的工作结温范围支持低温启动与高温长期运行,但反向漏电随温度上升会增加,设计时应考虑在高温工况下的漏电容忍度。
  • 对浪涌电流有一定承受能力(Ifsm 30A),但频繁的大浪涌或长时间超过额定电流会缩短寿命,应避免长期超出额定范围运行。

七、使用建议与注意事项

  • 芯片选择时注意正向压降 Vf 与系统功耗的平衡,850 mV@1A 在部分要求极低导通损耗的场合可能并非最佳选择;
  • 若需并联使用以提高电流能力,应保证良好热均衡与匹配,且并联二极管可能存在电流分配不均问题;
  • 回流焊与手工焊接时,遵循封装厂提供的焊接温度曲线,避免过热导致封装或性能退化;
  • 设计评估时参考详尽的厂方数据表(漏电随温度、Vf 随电流曲线、热阻参数等),以确保在应用场景中的可靠性与性能。

八、采购与技术支持

K110 由 GOODWORK(固得沃克)提供,封装为 SOD-123FL。采购前建议向供应商索取最新数据表、器件性能曲线及可靠性报告,并确认样片测试结果与目标应用的匹配度。若需替代型号或并联/散热优化建议,可联系 GOODWORK 的技术支持获取针对性的方案。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Replenishment inquiry Typical RFQ workflow
