SS36(FOSAN)肖特基二极管 产品概述

一、产品简介

SS36 为 FOSAN(富信)供应的一款肖特基整流二极管,封装为 SMA(表面贴装),额定直流整流电流 3A,最大反向耐压(Vr)60V。典型正向压降为 700mV@3A,非重复峰值浪涌电流(Ifsm)80A,室温下反向漏电流为 100μA@60V。器件工作结温范围宽(-65℃ 至 +130℃),适合多种中小功率电源及保护应用。

二、主要性能特点

  • 低正向压降:约 0.7V@3A,能减少整流损耗与发热,提升效率。
  • 快速开关特性:肖特基结构几乎无反向恢复,适合高频开关电源和快速整流场景。
  • 良好浪涌能力:非重复峰值浪涌电流达 80A(注意为脉冲规格,受波形与环境影响)。
  • 漏电流随温度上升显著增加:室温下 Ir≈100μA@60V,但高温条件下会大幅上升,需注意热设计。
  • 宽温度工作范围与常用 SMA 贴片封装,便于自动化贴装与批量生产。

三、典型应用场景

  • 开关电源后级整流、同步降压替代品或混合整流方案;
  • 负载反向保护、阻止回流或电池反接保护;
  • 电机驱动或继电器的自由轮二极管(中低压场合);
  • LED 驱动、汽车电子(在 60V 极限内)、太阳能逆变器辅助回路;
  • 各类直流降压/升压模块的快速整流与续流应用。

四、热管理与布局建议

  • 在最大额定电流 3A 连续工作时,器件功耗约 P = Vf × I ≈ 0.7V×3A ≈ 2.1W,SMA 封装对散热依赖 PCB 铜箔,需足够的铜面积(下方与两侧焊盘加大铜厚且多层过孔连接散热层)。
  • 对于高脉冲或高环境温度工作,应适当降额使用或采用更大封装(如 SMC)以保证可靠性。
  • 布局时减少环路面积,正负极走线加宽,焊盘应符合制造商推荐的 land pattern,遵循回流焊温度曲线避免过热损伤。

五、选型与使用注意事项

  • 若电路长期在高温或高反向电压下工作,应注意漏电流随温度呈指数上升,必要时选用更高耐压或低漏电型号。
  • Ifsm 为非重复峰值脉冲,不能作为连续冲击能力;频繁大电流冲击会导致老化或损坏。
  • 并联使用以提高电流能力时需注意电流均流问题,建议增加小阻抗或匹配器件并进行热均衡设计。
  • 在需要极低正向压降或更高功率散热要求的场合,可考虑封装更大、额定更高的肖特基替代品。

六、可靠性与测试建议

  • 在设计验证阶段进行热仿真与实测(结温、焊点温度、铜面积影响);
  • 测试项目建议包括正向压降随温度/电流曲线、反向漏电流随温度/电压曲线、脉冲浪涌能力验证以及长期温度循环试验。
  • 储存与焊接按制造商资料卡执行,避免潮湿引起焊接缺陷或焊点脆裂。

总结:SS36(FOSAN)以其低正向压降、快速切换和中等浪涌能力,适合许多中小功率整流与保护场合。但在高温、高功率或频繁冲击的应用中需重视热管理与降额设计。如需器件详细电气曲线、封装尺寸和推荐 land pattern,请参阅 FOSAN 官方数据手册或联系供应商获取完整资料。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
