SR560 产品概述
一、概述
SR560 是扬杰（YANGJIE）出品的一款独立式肖特基整流二极管，额定整流电流为 5A，直流反向耐压 60V，典型正向压降为 700mV（5A 测试条件下）。该器件采用 DO-201AD 轴向封装，适用于需要低正向压降、快速整流性能的中小功率电源与保护场合。
二、电气特性（主要参数）
- 型号：SR560（肖特基二极管）
- 正向压降：Vf ≈ 700mV @ If = 5A
- 直流反向耐压：Vr = 60V
- 连续整流电流：If(AV) = 5A
- 反向漏电流：Ir = 200μA @ Vr = 60V（温度升高时漏电流会显著上升）
- 封装：DO-201AD（独立式、轴向引线，便于通孔安装与手工焊接）
三、封装与热管理
DO-201AD 为轴向独立式封装，机械强度好、散热路径主要通过引线与封装本体传导。按典型计算：在 If = 5A、Vf = 0.7V 时，二极管功耗约为 3.5W（P = Vf × If），因此在连续大电流工作下应考虑散热设计。建议：
- 在 PCB 上使用加宽铜箔、加大焊盘或铜柱增强散热；
- 预留足够的空气对流空间或在必要时配合散热片；
- 在高温环境或频繁脉冲大电流情况下对额定电流进行适当降额。
四、典型应用场景
- 开关电源整流、次级输出整流；
- DC-DC 降压变换器的续流/钳位二极管；
- 反向极性保护与电源 OR-ing（并联备份电源）；
- 电机驱动、继电器回路的续流保护（中低压、高电流场合）；
- 具有较高开关频率要求但耐压不超过 60V 的应用。
五、使用建议与注意事项
- 反向漏电流：肖特基结构本身导致在较高反向电压与温度下漏电流较大（本器件为 200μA@60V），对低待机功耗系统或高温环境需谨慎评估；
- 耐压限制：Vr = 60V，超过此值会发生雪崩或击穿，选型时预留适当裕量；
- 热设计：遵循功耗计算（P = Vf×If）并结合 PCB 热阻进行电流降额；短时脉冲可承受峰值大于额定电流，但需参考脉冲能量与封装热容；
- 焊接：轴向封装便于手工或波峰焊，焊接时避免长时间高温加热以保护器件性能。
六、选型与替代考虑
若应用更看重更低正向压降，可寻找在同电流等级下 Vf 更低的高性能肖特基；若对漏电流要求严格或工作电压接近/超过 60V，应选用耐压更高的肖特基或普通整流二极管（硅整流）并评估正向损耗与恢复特性。总体上，SR560 在 5A/≤60V 的中等功率整流与保护场景中，凭借 DO-201AD 封装的机械稳定性与良好热传导表现，是性价比较高的选择。

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.
