SS54 肖特基二极管 产品概述
一、产品简介
SS54 为 GOODWORK(固得沃克) 出品的独立式肖特基整流二极管，封装为 SMA (DO-214AC)。该器件面向中大电流整流及开关电源应用，额定直流整流电流 5A，反向耐压 40V，典型正向压降为 0.55V（在 5A 条件下）。器件工作结温范围宽（-65℃ ~ +150℃），适应多种工业与消费类电子环境。
二、主要参数
- 二极管配置：独立式（单只肖特基二极管）
- 正向压降（Vf）：0.55V @ 5A
- 直流整流电流（Io）：5A
- 非重复峰值浪涌电流（Ifsm）：120A（单次浪涌）
- 直流反向耐压（Vr）：40V
- 反向电流（Ir）：100µA（典型，随温度增大）
- 工作结温：-65℃ ~ +150℃
- 封装：SMA (DO-214AC)
- 品牌：GOODWORK（固得沃克）
三、产品特性与优势
- 低正向压降：0.55V@5A 能显著降低整流损耗与系统发热，提升效率。
- 高浪涌能力：120A 的非重复峰值浪涌电流，适合带有启动冲击或瞬态电流的应用。
- 宽温度范围：适用于低温启动与高温工作场景，可靠性高。
- 封装通用：SMA 封装便于自动化贴装、手工焊接与散热设计。
四、典型应用场景
- 开关电源（SMPS）输出整流与输入保护
- DC-DC 转换器与降压模块
- 电池充放电路径、逆向保护与电源切换
- 倍压整流、整流桥替代及快速恢复整流场合
- 电机驱动与瞬态抑制电路
五、布局与散热建议
- 在 PCB 上为 SMA 封装预留标准焊盘，并加大铜箔面积以提升散热（尤其是在持续 5A 工作时）。
- 按照 Vf 约 0.55V、Io 5A 估算稳态耗散约 2.75W，需结合铜箔厚度与通孔散热评估结温。
- 注意反向泄漏随温度上升显著增加，高温场合应验算功耗与热阻，避免热失控。
六、可靠性与使用注意
- 非重复峰值浪涌为短时能承受能力，非长时间工作电流；频繁浪涌或高温下会缩短寿命。
- 反向电流在高温下升高，应在高温设计裕量中考虑漏电对系统的影响。
- 焊接工艺按 SMA 标准要求控制回流曲线，以保护器件性能。
GOODWORK SS54 以其低压降、高浪涌承受力与通用封装，适合需要高效率整流与紧凑布局的电源管理设计。购买与替换时请核对封装与电气参数以确保系统兼容性。

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.
