SS220 产品概述
一、产品简介
SS220 为扬杰（YANGJIE）出品的独立式肖特基二极管，SMB 封装，额定直流正向电流 2A，直流反向耐压 200V。典型正向压降为 900mV（在 2A 条件下），在 200V 反向电压下的反向漏电流约为 100µA。该器件将肖特基二极管的快速开关特性与中高压耐压能力结合，适用于多种电源与保护电路。
二、主要电气参数
- 正向压降（Vf）：900mV @ IF=2A
- 额定整流电流：2A（独立式散热条件下）
- 直流反向耐压（Vr）：200V
- 反向漏电流（Ir）：100µA @ VR=200V
- 封装形式：SMB（DO-214AA）
以上参数为典型/额定描述，具体使用时建议参照厂家完整数据手册中的温度依赖曲线与额定条件。
三、典型应用场景
- 开关电源的整流与续流（二极管作输出整流或续流元件）
- 反向极性保护，防止电池或外部电源接反
- DC-DC 转换器与充电器中的高频整流
- 光伏逆变器和工业电源中需耐高压且响应快的场合
四、封装与热管理建议
SMB 封装便于手工焊接与自动贴片生产，具备较好的封装可靠性。由于正向压降在 2A 时接近 0.9V，会产生显著的功耗（P=Vf×IF），使用时应注意热量散发：
- 在 PCB 上安排足够的铜箔散热区，增加焊盘和散热过孔；
- 保持二极管与热源组件有合理间距，避免局部过热；
- 在高连续电流场合考虑强制风冷或更大铜箔面积。
五、选型与使用注意
- 反向漏电流 100µA 在高阻态或待机功耗敏感的系统中需评估对整机漏电与温升的影响；
- 若应用有较大浪涌电流或高频脉冲，须查阅峰值冲击电流与热阻参数，评估安全余量；
- 多只并联并非最佳散流方案，若需更大电流宜选用额定电流更高的型号或并配热均衡设计；
- 焊接时遵循厂家给定的温度-时间曲线，避免因过热影响器件可靠性。
六、总结
SS220 在 200V 耐压与 2A 额定电流能力的基础上，提供了相对快速的开关响应与紧凑的 SMB 封装，适合需兼顾耐压与效率的中高压电源和保护应用。实际设计与长期可靠性评估应结合完整数据手册与系统热设计共同确认。若需替代型号或并联、散热方案建议，可提供具体电路与工况以便进一步优化。

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.
