US2D 系列快恢复高效率二极管产品概述
一、产品简介
US2D 为晶导微电子推出的独立式快恢复、高效率整流二极管，单颗SMA封装（DO-214AC）。器件正向压降低，开关性能良好，专为中小功率开关电源和整流场合设计，适配现代电源对效率与抗干扰的双重要求。
二、主要电气参数
- 正向压降：Vf = 1.0 V @ If = 2 A
- 直流反向耐压：Vr = 200 V
- 额定整流电流：If(AV) = 2 A
- 非重复峰值浪涌电流：Ifsm = 50 A
- 反向电流：Ir = 5 μA @ Vr = 200 V
- 反向恢复时间：Trr = 50 ns
- 工作结温范围：Tj = -55 ℃ ~ +150 ℃
三、产品特点与优势
- 低正向压降（1 V @ 2 A），可减少导通损耗，提高整机效率。
- 50 ns 的快恢复特性，有助于减少开关过渡过程中的能量损失与电磁干扰。
- 低反向漏电（5 μA @ 200 V），适合高压逆变及续流应用。
- SMA 小外形，利于密集布板与自动化贴装。
四、典型应用场景
- 开关电源（SMPS）整流与续流二极管
- DC-DC 转换器与适配器整流链路
- 电机驱动与伺服放大器的续流保护
- 太阳能逆变器、电池充放电管理电路
- 各类消费电子与工业电源的高效整流
五、封装与可靠性提示
- 封装：SMA（适合自动贴片与回流焊工艺，建议按照PCB制造商和焊膏供应商的回流曲线进行焊接）。
- 散热：器件热阻受PCB铜箔面积影响显著，建议在实际使用中通过加大铜箔面积或增加散热面以降低结温并做必要的电流热降额设计。
- 储存与处理：防潮防静电，避免机械应力与过热；焊接后建议做电气与机械性能验证。
US2D 结合了低损耗、快速恢复与小封装的优势，适合要求效率与可靠性并重的各类开关整流应用。如需完整规格书、封装尺寸或样品测试数据，欢迎联系晶导微电子获取更多技术支持。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
