SS210A 产品概述

一、产品简介

SS210A 是 FUXINSEMI(富芯森美)推出的一款独立式肖特基整流二极管,封装为 SMA (DO-214AC)。器件侧重于中等功率、高耐压场合,具有低正向压降、快速响应和宽工作温度范围的特点,适合各种电源整流、反向保护与续流应用。

二、主要参数

  • 器件类型:肖特基二极管(独立式)
  • 型号:SS210A
  • 正向压降:Vf = 0.85 V @ If = 2 A
  • 直流反向耐压:Vr = 100 V
  • 额定整流电流:2 A
  • 反向漏电流:Ir = 100 µA @ 100 V
  • 工作结温范围:-55 ℃ ~ +125 ℃
  • 封装:SMA (DO-214AC)
  • 品牌:FUXINSEMI(富芯森美)

三、产品特性与优势

  • 低正向压降:在 2 A 工作点 Vf≈0.85 V,减少整流损耗,提高系统效率(特别是在中等电流条件下)。
  • 中高耐压能力:100 V 的反向耐压使其可用于较高母线电压场合。
  • 快速响应:肖特基结构本征具备无明显反向恢复的优点,适合高开关频率电源与降压转换器中的续流/整流。
  • 宽温域工作:-55 ℃ 到 +125 ℃ 的结温范围,适配工业级环境。
  • SMA 封装:体积小,便于自动化贴装并在 PCB 上通过铜箔散热。

四、典型应用场景

  • 开关电源(SMPS)次级整流与续流二极管
  • 电池充电与充放电保护电路
  • 反向极性保护与浪涌保护
  • 太阳能逆变器及分布式能源系统的保护/整流
  • 汽车电子中对耐压和宽温度有要求的整流应用(需注意车规环境验证)

五、热管理与可靠性建议

在额定电流 2 A 下,器件功耗近似 Pd = Vf × If ≈ 1.7 W(0.85 V × 2 A)。由于 SMA 为小型封装,热阻相对较高,建议在设计时:

  • 在 PCB 上增加焊盘铜厚与面积,尽量使用多层散热铜箔以降低结到环境的热阻。
  • 对通流路径采用热过孔(thermal vias)将热量引导至内层/底层散热铜箔。
  • 按需进行电流/温度退化评估:计算 Tj = Ta + Pd × RθJA,确保在最大工作条件下结温不超过 125 ℃。
  • 注意反向漏流(IR)随温度上升快速增加,高温下可能影响小电流测量或微功耗电路,应在设计中留有裕量。

六、封装与安装注意事项

  • SMA (DO-214AC) 支持回流焊与手工焊接,建议遵循生产厂家提供的回流曲线(避免过高峰值温度和超时)。
  • 焊盘设计应考虑良好焊接性与散热,避免悬浮焊接或热阻过大。
  • 安装时注意极性标识,肖特基二极管对正负极敏感,反向接入会影响功能甚至损坏器件。
  • 储存与搬运注意防潮防静电,必要时使用防潮包装和 ESD 保护。

七、采购与技术支持

SS210A 由 FUXINSEMI(富芯森美)生产,封装为 SMA(DO-214AC),适合批量采购与自动化贴装。选型时建议索取并参照厂家完整数据手册、热阻及回流焊工艺规范,必要时可申请样片评估在目标系统中的热、电性能与可靠性表现。

总结:SS210A 在 100 V 耐压与 2 A 电流档位提供了平衡的正向压降与散热管理要求,适用于中等功率整流与保护场合。合理的 PCB 热设计与温度管理是发挥其性能并保证可靠性的关键。

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
