SS56 (DO-214AC) 肖特基二极管 — 产品概述
一、产品简介
SS56 为东沃（DOWO）品牌的一款功率肖特基整流二极管，封装为 DO-214AC（SMA），适用于中高电流整流与开关应用。该器件在 5A 工作电流下正向压降为 700mV（典型或最大值依测试条件而定），反向耐压为 60V，设计兼顾低正向压降与快速恢复特性，适合要求效率与热管理并重的电源场合。
二、主要电气参数
- 正向压降（Vf）：700mV @ 5A
- 额定整流电流：5A（直流）
- 直流反向耐压（Vr）：60V
- 反向电流（Ir）：标称在 60V 时为 100µA（描述中亦见 500µA 的条目，实际数值与温度、批次相关，请以厂商数据手册为准）
- 非重复峰值浪涌电流（Ifsm）：150A（单次脉冲峰值）
- 工作结温范围：-55℃ ~ +150℃
三、关键特性与优势
- 低正向压降：在高电流工况下能有效降低导通损耗，提升整体转换效率。
- 快速开关特性：肖特基结构固有的低存储电荷使其在高频开关场合表现良好。
- 宽温度范围：-55℃ 至 +150℃ 结温，适应工业级环境。
- 紧凑封装（SMA）：利于表面贴装设计，便于自动化装配并节省电路板空间。
四、典型应用场景
- 开关电源（SMPS）输出整流或同步整流替代器件。
- DC-DC 降压/升压转换器的续流/整流二极管。
- 车载电源与保护电路（符合 60V 等级的车规或工业电源）。
- 电池管理与充电器中的保护与整流。
- 逆变器、太阳能微型逆变器以及通信电源模块等需要高效率整流的场合。
五、封装与热管理建议
DO-214AC（SMA）为表面贴装封装，热量需通过焊盘与铜箔传导至 PCB。建议：
- 在焊盘下方或周围扩大铜箔面积，并增加热过孔（via）以提升散热能力。
- 在 5A 连续工作情形下评估结-焊盘热阻与 PCB 温升，必要时采用散热片或多层铜平面。
- 按厂商给出的回流焊曲线进行焊接，以保证可靠性与焊点质量。
六、选型与使用注意事项
- 反向漏电随温度显著上升，若工作环境偏高温需参考高温下 Ir 规格并预留裕量。
- 非重复峰值浪涌（Ifsm）仅适用于短时脉冲，宜避免长期重复大浪涌。
- 若应用对正向压降极度敏感，可比较同系列不同型号以降低 Vf（在特定电流点选择更低 Vf 的器件）。
- 采购时核对厂商数据手册，确认 Ir、Vf、Ifsm 等参数的测试条件与保证值，以免因批次或测试条件差异导致性能偏差。
七、总结
SS56（DOWO，DO-214AC）是一款面向中高电流与50~60V 等级电源应用的肖特基整流二极管，兼顾低导通损耗与快速开关特性，适合用于开关电源、DC-DC 转换器及各类电源保护场合。选型时应关注反向漏电在实际温度下的表现与 PCB 散热设计，以确保可靠运行与长寿命。若需更精确的电特性曲线或封装图纸，请参考制造商最新数据手册。

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.
