SS56A 产品概述

一、产品简介

SS56A 是富芯森美(FUXINSEMI)推出的一款独立式肖特基整流二极管,封装为 SMA(DO-214AC)。该器件面向中功率整流与保护应用,凭借肖特基结构具有较低的正向压降与快速开关特性,适用于开关电源输出整流、反向保护与低压快恢复要求的电路。

二、主要参数

  • 二极管配置:独立式
  • 正向压降(Vf):0.7 V @ 5 A
  • 直流反向耐压(Vr):60 V
  • 额定整流电流:5 A
  • 反向电流(Ir):500 nA(在额定条件下)
  • 非重复峰值浪涌电流(Ifsm):150 A
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SMA(DO-214AC)
  • 品牌:FUXINSEMI(富芯森美)

三、关键特性与优势

  • 低正向压降:0.7 V 在 5 A 条件下,有助于降低导通损耗与散热需求,提升整体效率。
  • 低反向漏电:典型反向电流为 500 nA,可在高阻抗或回路关断状态下减小泄漏功耗。
  • 良好浪涌承受能力:150 A 的非重复峰值浪涌能力,可应对启动瞬态或短时冲击电流。
  • 宽温度范围:-55 ℃ 至 +150 ℃ 的工作结温,使器件在工业级与汽车类环境中具有较好的热稳定性。
  • SMA 小型封装:适配紧凑 PCB 布局,便于自动化贴装和批量生产。

四、典型应用场景

  • 开关电源(SMPS)二次侧整流
  • 逆向保护、肖特基 OR-ing 电路、二极管束并联应用
  • DC-DC 转换器输出整流与滤波保护
  • 汽车电子 12V/24V 线路保护(需考虑环境与标准匹配)
  • 便携电源、充电器与电池管理系统的防反接或续流路径

五、热管理与可靠性注意

  • 尽管器件允许较高结温,但在持续 5 A 工作电流下应关注封装与 PCB 的散热能力。建议在布局层面放置热沉铜箔、加宽电源走线及增加焊盘面积,以降低结-焊点温升。
  • 在长时间高电流或高环境温度下,应进行功率损耗与结温计算,必要时通过降额使用或并联多颗器件分担电流。
  • 浪涌电流为非重复峰值能力,不能作为长期持续过载指标,实际系统设计应设置适当保护(如限流、保险丝或热关断电路)。

六、封装与使用建议

  • SMA(DO-214AC)封装适合自动贴装与波峰/回流焊工艺。焊接时遵循厂家焊接曲线与焊接工艺规范,避免超过封装和内部粘结材料的温度极限。
  • 储存与搬运时防潮防静电,开包后建议按常规电子元件元器件湿敏等级(MSL)处理并尽快回流焊接。
  • 采购时确认完整型号(SS56A)、生产批次与产品认证,必要时索取并参照富芯森美官方 Datasheet 以获取更详细的参数和测试条件。

七、选型与替代

SS56A 适用于需要 5 A 等级且反向耐压在 60 V 左右的场合。若系统对正向压降或反向泄漏有更严格要求,可考虑更低 Vf 或低 Ir 的肖特基型号;若需更高电流或更高耐压,应选择相应更大规格或不同封装的器件。选型时建议参考完整数据手册并在目标应用中进行热/电仿真与实测验证。

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
