SS84 产品概述
一、产品简介
GOODWORK（固得沃克）SS84 为独立式肖特基整流二极管，封装为 SMC（DO‑214AB）。该器件在高电流场合具有很小的正向压降与快速恢复特性，可替代普通整流二极管，以降低功耗并提高系统效率，适用于开关电源、DC‑DC 转换、整流及续流保护等场景。
二、主要电气参数
- 正向压降（Vf）：约 550 mV @ If = 8 A
- 额定整流电流：8 A（连续）
- 直流反向耐压（Vr）：40 V
- 反向漏电流（Ir）：100 μA @ 40 V
- 非重复峰值浪涌电流（Ifsm）：175 A
- 工作结温范围：-65 ℃ ~ +150 ℃
- 封装：SMC（DO‑214AB）
三、关键特性与优势
- 低正向压降：550 mV@8A 有效降低导通损耗，尤其在高电流条件下提升效率并减少发热。
- 低反向漏流：100 μA@40V 在高温或高压工况下仍能保持较低泄漏，有利于节能与静态功耗控制。
- 强浪涌承受能力：175 A（峰值）满足启动、短时过载或脉冲负载的冲击要求。
- 宽温区与高可靠性：结温支持高达 150 ℃，适配工业与汽车类温度环境（需按规范降额使用）。
- SMC 封装：热阻较小，便于散热设计与自动贴装工艺。
四、典型应用场景
- 开关电源整流与续流二极管（快速整流、降压/升压模块）
- DC‑DC 转换器输出整流、同步整流替代件
- 电池管理与充电系统的保护与整流
- 汽车电子（符合 12 V/24 V 系统中对 40 V 等级的使用需求）
- 通信电源、工业电源与电机驱动等需要高电流/低压降场合
五、散热与封装注意
- SMC（DO‑214AB）为大体积金属化封装，有利于通过铜箔散热；建议在 PCB 布局中采用大面积散热铜箔与多孔过孔连接底层散热层。
- 连续 8 A 工作时需进行热仿真与结‑环境温差评估，并按器件 SOA 与结温限制进行电流降额。
- 浪涌能量集中时需关注峰值热冲击，若系统存在频繁浪涌，应选择更高 Ifsm 或外加限流保护。
六、使用与可靠性建议
- 焊接建议遵循封装厂商的回流焊温度曲线，避免长时间高温升降；SMC 支持波峰/回流焊，但应控制热循环次数。
- 储存与防潮：未封装前防潮包装，避免湿气引发焊接问题。
- 在汽车或工业应用请留有安全裕量，按最高结温 150 ℃进行热管理与降额策略。
- 建议在设计中加电流检测与过温保护，防止长期高温导致寿命下降。
七、订购信息与标识
型号示例：GOODWORK SS84 — 封装 SMC（DO‑214AB）。订购时请确认批次、测试报告与 RoHS/REACH 等合规证书以满足项目要求。若需替代品或并联、散热方案咨询，可提供进一步的电热仿真与选型支持。

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.
