SS115 肖特基整流二极管产品概述

SS115是伯恩半导体(BORN)推出的1A/150V表面贴装肖特基整流二极管,采用SMA(DO-214AC)封装,以低漏电流、宽温工作、浪涌耐受能力强为核心特点,广泛适配中低压小功率整流场景,是工业控制、消费电子、通信设备等领域的常用器件。

一、产品核心身份与定位

SS115属于肖特基势垒型整流管,区别于普通硅整流管的PN结原理,其通过金属-半导体接触形成势垒,具备正向压降低、反向恢复时间极短(通常ns级)的优势。结合伯恩半导体的封装工艺,实现了宽温、高可靠性与成本的平衡,定位为“小功率、宽温、高性价比”的整流解决方案。

二、关键性能参数深度解析

SS115的参数围绕“安全工作范围”与“效率提升”设计,核心参数如下:

1. 基本整流能力

  • 直流反向耐压(Vr):150V:可稳定承受150V以下反向偏置,避免击穿,满足多数中低压电源需求;
  • 连续整流电流(If):1A:25℃环境下长期通过1A正向电流,175℃结温时降额至约0.5A,适配小功率负载;
  • 非重复峰值浪涌电流(Ifsm):30A:承受单次≤8.3ms的30A浪涌(如开机、负载突变),避免瞬间损坏。

2. 低功耗设计

  • 反向漏电流(Ir):100μA@150V:比普通硅整流管(mA级)低一个数量级,大幅减少待机/空载功耗,提升电源效率。

3. 宽温可靠性

  • 工作结温范围:-55℃~+175℃:覆盖工业级宽温(-40℃~+85℃)及高温场景(如汽车发动机舱周边),极端温度下性能稳定。

三、SMA封装的设计优势

SS115采用SMA表面贴装封装(尺寸约1.0mm×2.3mm×3.0mm),具备三大优势:

  1. 小型化适配:适合高密度PCB(如手机充电器、路由器),节省空间;
  2. 焊接可靠性:镀锡引脚抗腐蚀,回流焊/手工焊兼容性好;
  3. 散热效率:封装与PCB热耦合良好,快速散发布尔基结热量,支持高结温工作。

四、典型应用场景

SS115的参数特性适配多种小功率整流场景:

  1. 消费电子电源:手机/平板充电器、机顶盒、LED台灯的辅助整流,低VF(0.5~0.8V)提升充电效率;
  2. 工业控制模块:PLC输入输出电路、传感器信号整流,宽温适应车间高低温;
  3. 通信设备:基站射频模块、交换机电源的小电流整流,低漏电流保证信号稳定;
  4. 汽车电子辅助电路:车载氛围灯、后视镜控制模块整流(需确认结温≤175℃);
  5. 小型开关电源:5V/1A适配器、12V小功率电源的整流桥臂,浪涌耐受避免开机冲击。

五、选型与替换参考

1. 同品牌替换

  • 更高耐压:SS120(1A/200V)、SS130(1A/300V);
  • 更低耐压:SS110(1A/100V);
  • 更大电流:SS215(2A/150V,同SMA封装)。

2. 跨品牌替换

需匹配封装(SMA)、电流(1A)、耐压(≥150V),例如:

  • 安森美MBR115(1A/150V,SMA);
  • 东芝1SS115(1A/150V,SMA)。

六、使用注意事项

  1. 焊接规范:回流焊温度≤260℃(时间≤10s),手工焊温度≤300℃(时间≤2s),避免高温损坏结体;
  2. 散热设计:PCB焊盘面积≥5mm²,避免集中发热超175℃;
  3. 电压降额:反向电压建议≤120V(降额20%),延长寿命;
  4. 浪涌防护:避免频繁超30A浪涌(每小时≤10次),防止可靠性下降。

SS115凭借平衡的性能与成本优势,成为小功率整流领域的经典器件,适用于对效率、宽温、可靠性有要求的多数场景。

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
