U1D 产品概述

一、产品简介

U1D 是 YANGJIE(扬杰)推出的一款独立式快恢复高效率整流二极管,封装为 SOD-123FL,面向开关电源、适配器和各类功率管理电路。该器件在 1A 工况下具备较低的正向压降和快速的反向恢复特性,兼顾能效与开关性能,适合对热量和开关损耗有严格控制的应用场景。

二、主要参数概览

  • 正向整流电流:1A(连续)
  • 正向压降(Vf):0.92V @ 1A
  • 直流反向耐压(Vr):200V
  • 反向电流(Ir):5µA @ 200V
  • 非重复峰值浪涌电流(Ifsm):30A(单次脉冲)
  • 反向恢复时间(Trr):25ns
  • 工作结温范围(Tj):-55℃ ~ +150℃
  • 封装:SOD-123FL(独立式表贴)

三、关键特性与优势

  1. 低正向压降:0.92V@1A 有助于降低导通损耗,提高转换效率,尤其在持续整流或低压差场合更为明显。
  2. 快速恢复性能:25ns 的反向恢复时间使其在中高频开关应用中能有效降低开关损耗与电磁干扰(EMI)。
  3. 高耐压与低漏泄:200V 的反向耐压配合 5µA 的低反向电流,适用于高压输入体系且能减少待机能耗。
  4. 抗浪涌能力:30A 的单次浪涌承受能力,可应对启动或短时冲击电流,但应注意不作为长期重复浪涌使用。
  5. 紧凑表贴封装:SOD-123FL 提供良好的焊接可靠性与 PCB 布局友好性,适合自动化贴装工艺。

四、典型应用场景

  • 开关电源(SMPS)和电源模块的整流与续流
  • 手机充电器、适配器及便携类电源管理
  • LED 驱动与照明电源
  • 家电控制板、马达驱动中的保护与整流电路
  • 多路电源隔离、极性保护与反接保护电路

五、设计与使用建议

  • 热管理:器件额定 1A 连续电流与实际散热能力强相关,建议在 PCB 设计时增加铜箔面积以提高散热,必要时进行热仿真验证。
  • 浪涌处理:Ifsm=30A 适用于单次浪涌,应避免重复或长时间超过额定值。对可能发生的重复浪涌场合,请增加限流或保护元件。
  • 高频开关:Trr=25ns 提示在高频下能保持较低开关损耗,频率上限取决于电路拓扑与软恢复需求,应在实际电路中验证开关损耗与 EMI。
  • 焊接工艺:SOD-123FL 兼容主流回流焊工艺,建议遵循制造商提供的回流曲线与焊接指南以保证可靠性。

六、包装与订购说明

U1D 为独立式 SOD-123FL 封装,适配自动化贴装生产线。具体包装形式、最小订购量及可得性请参考 YANGJIE(扬杰)官方数据手册或联系授权分销商获取最新信息。

总结:U1D 将低导通损耗与快恢复特性结合于紧凑的表贴封装中,是面向中功率开关与整流场合的实用型二极管,适合在关注效率、热量与开关性能的设计中使用。有关电气特性曲线、热阻与可靠性试验数据,请以厂商数据手册为准。

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
