SSL54B 产品概述
一、概述
SSL54B 是扬杰（YANGJIE）推出的一款独立式肖特基整流二极管，采用 SMB 表面贴装封装（DO-214AA）。该器件具有低正向压降和快速恢复特性，适合开关电源、高效整流与反向保护等场合，既满足高效率要求又兼顾可靠性。
二、主要参数
- 二极管配置：独立式（单只二极管）
- 正向压降（Vf）：450 mV @ 5 A
- 直流反向耐压（Vr）：40 V
- 直流正向整流电流：5 A
- 反向漏电流（Ir）：500 μA @ 40 V
- 非重复峰值浪涌电流（Ifsm）：100 A
- 工作结温范围：-55 ℃ ~ +150 ℃
- 封装：SMB（DO-214AA）
三、产品特点
- 低正向压降：450 mV @5 A，有助于降低整流损耗，提高系统效率。
- 耐浪涌能力强：100 A 峰值浪涌电流，适应开机冲击与突发负载。
- 宽温度范围：-55 ℃ 至 +150 ℃，适应工业级环境。
- SMB 封装：便于自动贴装与良好焊接强度，散热面积适中。
- 反向泄漏受控：在 40 V 下 Ir ≤ 500 μA，适合一般电源应用的反向稳态要求。
四、典型应用
- 开关电源（SMPS）输出整流与二次侧整流
- 电池充放电保护与反向保护电路
- DC-DC 转换器、适配器、电源模块
- 太阳能逆变、汽车电子（需确认温度与耐压匹配）
- 需高效整流与抗浪涌的工业电源场合
五、封装与热管理
SMB 表面贴装封装方便自动化生产，建议在 PCB 设计时为阴极/阳极两侧留充足的铜箔面积以增强散热并降低结温。关键的热设计要点包括短低感应封装走线、增加热铜平面及必要时开通热通孔（thermal vias），保证在 5 A 工作电流下保持安全的结温和可靠性。
六、设计与使用建议
- 在高频整流场景下，肖特基的低正向压降可显著降低损耗，但请注意反向漏流随温度上升而增加，需评估系统在高温下的静态功耗。
- 对于浪涌要求较高的系统，应结合 Ifsm 与周期/次数限制选择合适的箝位或预充电策略。
- 焊接工艺需遵循供应商回流曲线，避免过热造成器件性能退化。器件极性通过封装标记（阴极带）识别。
七、可靠性与质量保证
SSL54B 面向工业与消费市场研发生产，符合扬杰出货检验流程。建议在量产前进行样片验证（含温度极限、热循环及浪涌测试），并在关键应用场景下完成长期老化验证与电气可靠性评估。

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.
