CRS08 产品概述

一、产品概况

CRS08 是 SHIKUES(时科)推出的一款独立式肖特基二极管,封装为 SOD-123FL。该器件针对低压高速整流和保护场合优化,具有较低的正向压降与快速响应特性,适合开关电源、DC-DC 转换器、车载及便携设备的整流与反向保护应用。

二、主要参数

  • 二极管类型:肖特基二极管(独立式)
  • 正向压降:Vf = 0.55 V @ 2 A
  • 直流反向耐压:Vr = 40 V
  • 额定整流电流:1.5 A(连续)
  • 反向漏电流:Ir = 500 μA @ 40 V
  • 工作结温:-55 ℃ ~ +125 ℃
  • 非重复峰值浪涌电流:Ifsm = 50 A(单次瞬态,具体测定条件以厂家资料为准)
  • 封装:SOD-123FL

三、主要特性与优势

  • 低正向压降(0.55 V@2 A),降低导通损耗,提升效率,尤其在低电压大电流场合显著。
  • 肖特基结构带来极短的恢复时间,适合高频开关环境,减少开关损耗与电磁干扰。
  • 小型 SOD-123FL 表面贴装封装,便于高密度 PCB 布局与自动化贴装生产。
  • 宽工作温度和较高的浪涌能力,满足工业级与车载级部分需求。

四、典型应用场景

  • 开关电源二次侧整流、低压快恢复整流;
  • DC-DC 转换器输入/输出整流;
  • 逆向防护与反接保护电路;
  • 电池管理、移动设备与便携式电源的功率通路;
  • 低压电机驱动与车载电子(留意热管理与耐压要求)。

五、封装与热管理建议

SOD-123FL 为小型 SMT 封装,散热主要依赖 PCB 铜箔与焊盘设计。建议:

  • 在器件下方和焊盘周围使用适度的露铜和过孔以增强散热;
  • 连续工作电流接近额定值时应做热仿真与实测,必要时采用更大铜量或散热垫;
  • 焊接时遵循厂家推荐的回流曲线,避免超温损伤器件可靠性。

六、选型与使用注意

  • 持续工作时不要超过额定整流电流 1.5 A,若有长时间高负载需求请按热阻与结温进行降额设计;
  • 反向漏电流随温度显著增加,在高温或高压偏置场合需评估漏电对系统的影响;
  • 非重复峰值浪涌 50 A 能承受短时浪涌,但应避免频繁或长期冲击,必要时并联或选择更高浪涌能力器件;
  • 设计时预留安全裕度,避免长期在 Vr=40 V 近限值工作。

七、可靠性与品质控制

该型号适配一般工业级温度范围(-55 ℃ ~ +125 ℃)。在关键应用中建议做以下验证:温度循环、恒温恒湿、峰值浪涌与反复冲击测试、以及焊接热稳定性试验。采购时请向供应商确认批次试验报告与质量控制文件。

八、结论

CRS08(SHIKUES/时科,SOD-123FL)凭借低正向压降、快速响应和小型封装,在低压整流与保护场景中具有良好性价比。使用时需注意热管理与漏电随温度上升的影响,根据实际电流与热条件合理降额设计,以确保长期可靠运行。若需完整数据手册、封装图或回流焊规范,请向 SHIKUES(时科)或授权经销商索取。

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
