扬杰YANGJIE SS515B肖特基二极管产品概述

扬杰电子(YANGJIE)推出的SS515B是一款独立式肖特基二极管,采用SMB(DO-214AA)标准表面贴装封装,凭借低导通损耗、宽环境适应性、强抗浪涌能力等核心优势,成为中等功率电子电路中整流、续流的高性价比器件,广泛应用于开关电源、车载电子、LED驱动等场景。

一、产品基本定位与封装

SS515B属于独立式肖特基二极管,无并联/串联集成结构,单个器件独立封装,便于电路灵活布局。其采用的SMB(DO-214AA)封装为表面贴装形式,尺寸紧凑(典型尺寸约3.5×2.5×1.5mm),适配自动化贴片生产,可有效节省电路板空间,尤其适合便携式充电器、车载控制模块等小型化电子设备的设计需求。

二、核心电气参数解析

SS515B的关键参数针对中等功率应用优化,具体特性如下:

  • 正向压降(Vf):900mV@5A,正向电流5A时电压降仅0.9V,比传统硅整流二极管(通常≥1V)低10%以上,显著减少导通损耗,提升电路效率;
  • 直流反向耐压(Vr):150V,长期反向耐压额定值满足12V/24V等低压电源的反向截止需求,避免击穿损坏;
  • 整流电流(If):5A,长期连续正向电流额定值,直接满足中小功率电路的整流、续流需求,无需额外降额;
  • 反向漏电流(Ir):100uA@150V,反向电压150V时漏电流仅100微安,漏电流小则反向截止发热少,器件可靠性更高;
  • 非重复浪涌电流(Ifsm):100A,单次非重复浪涌电流最大值,可抵御电路启动瞬间、瞬态干扰的大电流冲击;
  • 工作结温范围:-55℃~+150℃,覆盖极端高低温环境,适应车载、户外等复杂工况,无需额外散热即可稳定工作。

三、典型应用场景

结合参数特性,SS515B主要应用场景包括:

  1. 开关电源与DC-DC转换器:低Vf减少导通损耗,肖特基固有的短反向恢复时间(典型特性)降低开关损耗,提升电源转换效率,适配高频开关电路;
  2. 车载电子系统:宽结温范围适应汽车高低温环境,100A浪涌能力抵御启动大电流,可用于车载充电器、中控电源模块;
  3. LED驱动电路:正向压降与中功率LED匹配,5A电流满足LED阵列需求,小漏电流减少反向漏电对LED的影响;
  4. 小型家用电器电源:如智能充电器、路由器电源等,SMB封装节省空间,5A电流覆盖多数小家电功率范围;
  5. 续流二极管:用于电感负载电路(电机驱动、继电器),短反向恢复时间减少电感放电电压尖峰,保护电路元件。

四、产品优势与价值

SS515B的核心优势转化为实际设计价值:

  • 高效节能:低Vf+小Ir双维度降损,电源转换效率提升3%~5%,适合能效要求高的应用;
  • 宽温可靠:结温覆盖极端环境,故障率低,适配车载、户外等恶劣工况;
  • 抗冲击耐用:100A浪涌能力避免瞬态冲击损坏,延长电路寿命;
  • 生产适配:SMB贴装支持自动化生产,提升效率、降低人工成本;
  • 品牌保障:扬杰电子经过严格可靠性测试(温度循环、浪涌测试),品质稳定,供货周期短。

五、总结

SS515B肖特基二极管凭借平衡的电气性能、紧凑封装、可靠环境适应性,成为中等功率电路的高性价比选择。无论是追求效率的开关电源,还是适应恶劣环境的车载系统,均能提供稳定高效的整流/续流解决方案,满足多样化应用需求。

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
