SS38 肖特基二极管（晶导微电子）产品概述
一、产品简介
SS38 为晶导微电子推出的一款功率肖特基整流二极管，SMA 封装，面向中功率开关电源与整流应用。器件以低正向压降和快速响应为特点，适合在需要提高转换效率与减小功耗的场合替代普通整流二极管。
二、主要参数与性能
- 正向压降（Vf）：0.85V @ If = 3A
- 直流反向耐压（Vr）：80V
- 整流电流（IF）：3A（连续）
- 反向电流（Ir）：300µA @ 80V
- 非重复峰值浪涌电流（Ifsm）：80A
- 工作结温范围：-55℃ ~ +150℃
- 封装：SMA
- 品牌：晶导微电子（Jingdao）
三、关键特性与优点
- 低正向压降：在大电流工况下减少导通损耗，提升系统效率并降低发热。
- 低反向恢复：肖特基结构本征优势，适合高频开关电源和快速切换电路，减少开关损耗与电磁干扰。
- 耐冲击能力强：80A 峰值浪涌电流能承受短时突发电流，提升可靠性。
- 宽温度范围：-55℃~150℃ 的工作结温支持工业级环境。
四、典型应用场景
- 开关电源（SMPS）输出整流与取样回路
- DC-DC 变换器与同步整流替代
- 二极管保护（极性保护、反向电压保护）
- 电池充放电路径、太阳能逆变器辅助整流
- 电机驱动、汽车电子低压整流（需符合系统级要求）
五、封装与热管理
SMA 封装支持自动贴片与回流焊加工，适合批量生产。实际使用时需关注PCB散热：高整流电流条件下建议增大铜箔面积、添加散热铜柱或热过孔以降低结温并保证长期可靠性。
六、使用与选型建议
- 在选型时注意正向压降随电流和温度上升的变化，必要时参照器件完整数据表。
- 对于高温或高反向电压工况，应关注反向漏电随温度上升的增加，评估对系统功耗的影响。
- 若应用要求更低漏电或更高耐压，可考虑更高规格的肖特基或硅整流器。
七、可靠性与注意事项
为保证长期稳定性，建议遵循晶导微电子提供的焊接曲线与储存条件，避免长时间在高温高湿环境下暴露。实际电路设计中应考虑浪涌保护与过热保护措施，确保器件不超过额定结温与峰值电流。
如需器件完整电气特性曲线、封装机械尺寸或环境与可靠性试验数据，请参考晶导微电子官方数据手册或联系供应商获取最新资料。
Request for quote
Send RFQ
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.
