SS210HE 肖特基二极管产品概述

SS210HE是东沃(DOWO)电子推出的一款小功率表面贴装肖特基整流二极管,属于其SS系列肖特基产品线,以100V直流反向耐压、2A最大整流电流为核心参数,搭配SOD-123HE紧凑封装,针对消费电子、LED驱动、小型开关电源等场景设计,兼顾效率与小型化需求。

一、产品核心身份与定位

SS210HE定位于中低压小功率肖特基整流应用,填补了“100V耐压+2A电流+小封装”的市场空白。其型号命名规则清晰:“SS”代表肖特基二极管(Schottky Rectifier),“210”中“2”对应2A整流电流、“10”对应100V反向耐压,“HE”为封装后缀(对应SOD-123HE)。产品主打高性价比与高可靠性,适配批量标准化应用场景。

二、关键电气性能参数

SS210HE的核心电气参数围绕肖特基二极管的“低损耗、快速开关”特性设计,关键指标如下:

  • 直流反向耐压(V₍R₎):100V(最大额定值,连续工作电压需降额);
  • 最大整流电流(I₍F₎):2A(环境温度25℃时的连续峰值电流);
  • 正向压降(V₍F₎):典型值0.55V(@I₍F₎=2A,25℃),最大值0.65V(同条件);
  • 反向漏电流(I₍R₎):典型值10μA(@V₍R₎=100V,25℃),最大值50μA(同条件);
  • 反向恢复时间(t₍rr₎):典型值10ns(肖特基二极管无明显恢复拖尾,适合高频应用);
  • 工作温度范围:-55℃~+150℃(符合工业级温度要求)。

三、封装设计与物理特性

SS210HE采用SOD-123HE表面贴装封装,是SOD-123系列的紧凑升级款,物理特性适配高密度PCB设计:

  • 封装尺寸:长3.8mm×宽2.5mm×高1.1mm,引脚间距1.27mm;
  • 封装材料:环氧树脂塑封(符合RoHS 2.0、无卤素标准),耐湿热与机械冲击;
  • 极性标识:封装顶部的色环为阴极(负极),焊接时需注意正向导通方向(阳极接低电位、阴极接高电位);
  • 焊接兼容性:支持回流焊(峰值温度260℃,持续时间≤30s)、波峰焊(峰值温度240℃,持续时间≤5s)。

四、典型应用场景

结合SS210HE的参数与封装特性,其典型应用集中在低压小功率高频电路:

  1. 小型开关电源:AC-DC适配器(5V/2A、12V/1A)的次级整流、DC-DC转换器的续流二极管;
  2. LED驱动电源:低压LED灯带(12V/2A)、小功率LED球泡的整流与续流;
  3. 消费电子:手机充电器、平板电源、蓝牙耳机充电盒的内部整流电路;
  4. 车载电子:12V车载系统的小功率辅助电源(如点烟器适配器、行车记录仪电源);
  5. 工业控制:小型PLC、传感器模块的低功耗电源电路。

五、核心优势与价值

SS210HE的核心竞争力体现在以下三点:

  1. 低损耗效率:正向压降仅0.55V(典型值),比普通硅整流管低40%以上,可有效降低电源功耗,提升转换效率(尤其在5V、12V低压系统中);
  2. 高频适配性:反向恢复时间<10ns,无恢复拖尾,适合100kHz~500kHz的高频开关电源,避免开关损耗;
  3. 小型化优势:SOD-123HE封装比传统DO-214AC(SMA)封装体积小30%,可节省PCB空间,适配超薄、小型化产品设计;
  4. 高可靠性:符合工业级温度范围,塑封材料耐老化,批量应用故障率低,适合长期稳定工作场景。

六、选型与应用注意事项

为确保SS210HE的稳定工作,应用时需注意以下要点:

  1. 电压降额:实际工作反向电压建议不超过80V(留20%裕量),避免过压损坏;
  2. 电流降额:连续工作电流建议≤1.5A(环境温度≥85℃时需进一步降额至1A以内),脉冲峰值电流(I₍FSM₎)最大30A(8.3ms单脉冲);
  3. 散热设计:PCB铜箔需预留足够面积(建议≥2mm²),避免局部过热;高温环境下可增加散热片;
  4. 极性焊接:严格区分阳极(无标识端)与阴极(色环端),反接会导致反向击穿;
  5. 存储条件:未焊接器件需存储在常温干燥环境(温度-10℃~+40℃,湿度≤60%),避免受潮影响焊接性能。

SS210HE凭借“高耐压、大电流、小封装、低损耗”的综合优势,成为小功率肖特基应用的高性价比选择,适配多领域的标准化设计需求。

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.
