SS1045-SMB 产品概述
一、概述
SS1045-SMB 是 GOODWORK（固得沃克）推出的一款独立式肖特基整流二极管，封装为 SMB（DO-214AA）。该器件在10A工作电流时正向压降典型为 550mV，直流反向耐压 45V，反向电流仅 100nA，整流电流标称 10A，兼具低正向压降和快速恢复特性，适用于中大电流、高效率电源及保护电路。
二、主要性能特点
- 低正向压降：Vf = 550mV @ 10A，减小导通损耗，提升效率并降低发热。
- 中等耐压：Vr = 45V，适合常见的12V/24V车载与工业电源系统以及部分开关电源拓扑。
- 低漏电流：Ir = 100nA（典型），在待机或高温下有利于减少静态损耗（注：实际漏电随温度上升）。
- 大电流能力：整流电流 10A，适合整流、自由轮回和功率保护用途。
- SMB 封装：适用于表贴工艺，具有良好的热扩散路径与焊接强度。
三、典型应用场景
- 开关电源（SMPS）整流输出与同步整流替代件。
- 车载电源与负载保护（12V/24V 系统）。
- 电机驱动与 MOSFET 自由轮二极管（freewheeling）。
- 续流、反接保护、电池管理与太阳能微逆变器。
- 高效率整流桥与点对点功率传输场合。
四、封装与热管理建议
SMB（DO-214AA）为体积适中、焊点可靠的表贴封装。为保证 10A 连续工作可靠性，建议在 PCB 设计中：
- 增大焊盘面积并使用多层铜平面以增强散热。
- 在焊盘下或周围布置若干过孔（热通孔），将热量传导到内层或底层散热铜箔。
- 保持良好焊点，避免长期高温堆积导致热应力。
切记评估整机环境温度和散热路径，依据功耗计算热升以决定是否需要散热片或额外冷却。
五、焊接与使用注意
- 遵循常规回流焊温度曲线，避免长时间高温暴露以防封装性能退化。
- 表面贴装时注意器件极性标识，防止反装。
- 储存与搬运注意防潮和静电保护（ESD）。
- 在高温或高电流应力下，定期验证漏电流与正向压降是否在规格范围内。
六、选型参考与替代方案
在选型时，应综合考虑正向压降、耐压、漏电、最大平均整流电流及封装散热能力。若系统工作电压高于45V，应选用更高 Vr 的肖特基或其他整流方案；若需更低 Vf，可考虑特殊工艺或并联多只器件以分散热量；若对反向漏电高度敏感，可选漏电更低的型号并关注温度特性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
