SS515B 产品概述

一、产品简介

SS515B 是晶导微电子推出的一款高压肖特基整流二极管,采用 SMB(DO-214AA)封装。器件为单向肖特基结构,面向中大电流整流与开关电源回路保护,兼顾低正向压降与较高耐压能力,适用于工业与消费类电源设计。

二、主要参数

  • 正向压降 (Vf):0.85V @ 5A
  • 额定整流电流:5A(连续)
  • 直流反向耐压 (Vr):150V
  • 反向漏电流 (Ir):300µA @ 150V
  • 非重复峰值浪涌电流 (Ifsm):150A(短时浪涌)
  • 工作结温范围:-55℃ ~ +150℃
  • 封装:SMB

三、关键特性

  • 低正向压降:在高电流条件下仍保持较低Vf,有助于降低导通损耗与系统发热。
  • 高耐压设计:150V 反向耐压适合较宽电压余量的电源与工业应用。
  • 良好浪涌承受能力:短时浪涌电流150A,可应对启动或瞬态冲击。
  • 宽温区可靠性:-55℃~+150℃的结温范围,适应恶劣环境工作。

四、典型应用

  • SMPS整流与次级整流
  • DC-DC 转换器输出整流
  • 续流/自由轮二极管
  • 逆接保护与电池管理系统
  • 工业电源与汽车电子(需根据系统温度与漏电要求评估)

五、封装与热管理建议

SMB 封装利于自动贴装与较好散热。典型建议:在PCB上提供大面积铜箔和热铜垫,必要时加装散热板或多层热过孔,以降低结温。注意:在5A 连续工作且 Vf≈0.85V 时,器件功耗约为4.25W,需合理计算并保证热阻和环境散热能力。

六、使用注意事项

  • 反向漏电随结温上升显著增加,高温工况需评估泄漏对系统的影响。
  • 峰值浪涌仅为短时能力,不可作为长期过载工作条件。
  • 布局时尽量缩短高电流回路环路,减小寄生电感与纹波。
  • 具体热阻及浪涌测试波形/条件以晶导微电子正式数据手册为准,设计前建议参考原厂完整规格表并留有余量。

SS515B 提供在中高压与中大电流场景下的可靠整流解决方案,兼顾成本与性能,适合要求稳定性与耐久性的电源设计。若需更详细的电气特性曲线与封装尺寸,请参阅晶导微电子产品资料或联系供应商获取样片与评估报告。

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.

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
