US5DCG 产品概述

一、产品简介

US5DCG 为 SHIKUES(时科)推出的一款独立式快恢复/高效率整流二极管,采用 SMC 封装,面向中高压开关电源、逆变器及电机驱动等需兼顾效率与开关性能的电力电子场合。器件在 5A 连续整流电流下具有较低的正向压降与快速恢复特性,适合替代传统缓恢复整流器以提升系统效率与减小 EMI。

二、主要技术参数

  • 器件型号:US5DCG(SHIKUES / 时科)
  • 封装:SMC(独立式)
  • 连续整流电流:5A
  • 反向耐压(Vr):200V
  • 正向压降(Vf):1.0V @ If = 5A
  • 反向电流(Ir):≤5μA @ Vr = 200V
  • 反向恢复时间(Trr):≈50ns
  • 工作结温范围(Tj):-55℃ ~ +150℃

三、关键特性与优势

  • 低正向压降:在 5A 条件下 Vf ≈1.0V,减小导通损耗,有利于提高整机效率。
  • 快恢复性能:Trr ≈50ns,开关损耗与反向恢复导致的电压尖峰较小,适合中高频开关应用。
  • 低反向泄漏:在 200V 条件下 Ir ≤5μA,有助于降低高压空载损耗和热应力。
  • 宽温区稳定:-55℃至+150℃的结温范围,适应工业环境的温度变化。
  • 标准封装:SMC 便于手工焊接与自动化贴装,散热与机械强度兼顾。

四、典型应用

  • 开关电源(SMPS)中的输出整流与续流二极管
  • 功率因数校正(PFC)电路中的高压整流
  • 逆变器与 UPS 系统的整流与自由轮回路
  • 直流电机驱动、太阳能逆变器及其他功率电子模块
  • 通用电源保护与续流场合

五、热管理与 PCB 布局建议

  • 在 5A 工作点下,器件正向导通损耗约为 Vf × I ≈ 5W,需注意热流散与结温控制。建议配合足够的铜厚和散热片,保持结温远低于 150℃。
  • SMC 封装应使用对应的 PCB 焊盘与散热孔设计,扩大散热铜箔并增加过孔连接多层散热层。
  • 在高频开关场合,布局上应靠近功率开关与磁性元件,缩短电流回路并在需要处添加旁路电容和抑制 RC/TVS 以缓解开关尖峰。

六、可靠性与使用注意事项

  • 请参考完整数据表获取最大浪涌电流(IFSM)、功率耗散与热阻等参数,以便进行精准热设计与过载保护。
  • 在高温或高电压长期工作时应采取适当降额(derating),保证器件长期可靠性。
  • 焊接时注意温度曲线与回流规范,避免过热导致封装或性能退化。
  • 对于敏感应用建议加装保护元件(熔断器、限流电阻或 TVS)以防突发浪涌或反向过压。

七、封装与订购信息

  • 封装:SMC,便于批量装配与散热设计。
  • 品牌:SHIKUES(时科)。型号 US5DCG,适用于需要 200V 耐压与 5A 整流能力的中功率电路。
  • 订购时请确认完整料号与包装形式(卷带/散装/托盘),并索取最新数据手册以核对所有极限参数与典型曲线。

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
