SS210F 肖特基二极管产品概述

一、产品基本信息

SS210F是MDD品牌推出的独立式肖特基整流二极管,采用SMAF表面贴装封装(薄型SMA封装),属于低压大电流高效整流器件。该产品针对低功耗、高频切换场景优化,兼顾小尺寸与高可靠性,广泛适配消费电子、工业控制及汽车电子等领域的低压整流需求。

二、核心电性能参数

SS210F的电性能参数围绕“低正向压降、快恢复、宽温稳定”设计,关键指标如下:

  • 正向压降(Vf):850mV@2A(典型值)—— 远低于普通硅整流管(通常1V以上),可显著降低整流损耗,提升电源效率;
  • 直流反向耐压(Vr):100V(额定值)—— 满足低压AC-DC/DC-DC转换的反向阻断需求;
  • 整流电流(If):2A(额定直流电流)—— 持续承载2A负载电流,峰值电流能力更强(典型值[email protected]);
  • 反向漏电流(Ir):300μA@100V(25℃)—— 反向漏电流小,减少待机功耗;高温下(150℃)漏电流≤5mA,仍保持低损耗;
  • 反向恢复时间(trr):典型值50ns(肖特基二极管固有特性)—— 适合高频切换场景(如开关电源、DC-DC转换器),无明显反向恢复尖峰;
  • 工作结温范围:-55℃~+150℃—— 覆盖工业级宽温环境,适应户外、车载等 harsh 场景。

三、封装与物理特性

SS210F采用SMAF封装(符合JEDEC标准),物理特性如下:

  • 封装尺寸:约2.0mm(宽)×3.0mm(长)×1.0mm(厚)—— 小尺寸节省PCB空间,适配高密度设计;
  • 引脚材质:镀锡铜合金—— 焊接性能优异,兼容回流焊、波峰焊工艺(回流焊温度260℃/30s);
  • 封装材料:耐高温环氧树脂—— 耐湿热、抗机械冲击,符合RoHS 2.0及REACH环保标准;
  • 极性标识:封装侧面印有“阴极”标识(通常为黑色条带),便于焊接时识别方向。

四、典型应用场景

SS210F因低Vf、快恢复及小尺寸特性,主要应用于以下场景:

  1. 开关电源整流:AC-DC适配器(如手机/笔记本充电器)、LED驱动电源的低压输出整流,降低损耗提升效率;
  2. DC-DC转换器:Buck/Boost电路的续流管,利用快恢复特性减少切换损耗,适配高频(100kHz~1MHz)设计;
  3. 电池保护电路:锂离子电池组的反向电流阻断(如电动车BMS、便携式设备电池),100V反向耐压满足安全需求;
  4. 工业控制:PLC、伺服驱动器的辅助电源整流,宽温范围适应车间高低温环境;
  5. 小型家电:微波炉、电风扇的控制板电源整流,小尺寸适配紧凑PCB布局。

五、可靠性与环境适应性

SS210F通过多项可靠性测试,确保长期稳定运行:

  • 高温寿命测试:1000h@150℃,性能无明显衰减;
  • 湿热测试:85℃/85%RH下1000h,反向漏电流变化≤10%;
  • 机械可靠性:引脚拉力≥5N,封装抗冲击(1000g/0.1ms);
  • 存储温度:-65℃~+175℃,便于运输与仓储。

六、选型与替换参考

  • 同系列升级:若需更大电流,可选择MDD SS310F(3A/100V,SMAF封装);若电流需求1A,可替换为SS110F;
  • 跨品牌替换:可兼容Diodes SS210(DPAK封装)、ON Semiconductor MBR210(SMA封装),但需注意封装尺寸匹配;
  • 注意事项:因肖特基二极管反向耐压低于硅整流管,需避免在高压场景(如200V以上)使用。

SS210F以高性价比、稳定性能成为低压整流场景的主流选择,适配多领域的高效电源设计需求。

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
