SS36肖特基二极管产品概述

SS36是钜兴(JUXING)品牌推出的独立式肖特基二极管,采用SMA(DO-214AC)表面贴装封装,针对中低压整流、续流等场景优化设计,核心参数覆盖3A直流整流电流、60V反向耐压,兼具低正向压降、宽温范围等肖特基二极管典型优势,适用于消费电子、工业控制、车载电子等多领域。

一、核心参数精准梳理

SS36的关键参数匹配中小功率应用需求,具体如下:

  • 正向特性:正向压降(Vf)仅700mV(@3A直流电流),远低于传统硅整流管(如1N4007)的导通损耗,可有效降低电源转换中的热损耗,提升整体效率;
  • 反向特性:直流反向耐压(Vr)60V,反向漏电流(Ir)500μA(@30V反向电压),反向特性稳定,可减少待机功耗,提升电路可靠性;
  • 电流能力:直流整流电流3A(连续工作),非重复峰值浪涌电流(Ifsm)70A(脉冲时间≤8.3ms),可应对开机瞬间、负载突变等脉冲冲击,避免器件损坏;
  • 温度范围:工作结温覆盖-55℃至+150℃,满足工业级宽温环境需求,适应极端温度场景(如车载、户外设备)。

二、封装与物理特性

SS36采用SMA(DO-214AC)表面贴装封装,具备以下特点:

  • 小型化设计:封装尺寸紧凑,节省PCB空间,适合便携式设备、高密度电路板的集成;
  • 贴装兼容性:表面贴装引脚设计,支持自动化贴片生产,焊接工艺成熟,良率高;
  • 热 dissipation:封装结构利于热量传递,配合PCB散热焊盘可有效降低结温,保障高电流下的工作稳定性。

三、典型应用场景解析

SS36的参数特性使其适配多类应用场景:

  1. 开关电源次级整流:如手机充电器、小型适配器、LED驱动电源等,低Vf可减少导通损耗,提升电源效率(如12V/2A电源中,Vf700mV比1V压降减少约0.3W损耗);
  2. 直流-DC转换器:如车载电子(行车记录仪、车载充电器)、便携式设备(移动电源),宽温范围可适应车载环境的温度波动;
  3. 续流二极管:如电机驱动电路、继电器续流回路,肖特基二极管的快速恢复特性可减少反向尖峰电压,保护电路元件;
  4. 小功率电源保护:如过流后的续流回路、电压钳位电路,70A浪涌能力可应对瞬间脉冲,避免器件击穿。

四、性能优势总结

相比同功率段的传统硅整流管,SS36具备以下核心优势:

  • 低损耗高效:700mV低Vf减少导通热损耗,无需额外散热片即可满足中小功率需求;
  • 宽温可靠:工业级温度范围,适应极端环境,降低环境温度对器件性能的影响;
  • 抗冲击强:70A浪涌电流能力,提升电路抗脉冲干扰能力;
  • 体积紧凑:SMA封装适合小型化设备,符合电子设备轻薄化趋势;
  • 性价比高:均衡的参数与成熟工艺,成本优势明显,适合批量应用。

五、选型与使用注意事项

为保障SS36的稳定工作,需注意以下要点:

  1. 电压降额:实际应用中反向耐压建议降额至70%(即≤42V),避免过压损坏;
  2. 电流降额:直流电流需结合环境温度降额(如25℃时≤2.4A,100℃时≤1.8A),避免结温过高;
  3. 焊接规范:回流焊温度≤260℃(时间≤10秒),手工焊温度≤350℃(时间≤3秒),防止热损伤;
  4. 散热设计:PCB散热焊盘面积建议≥10mm²,或增加铜箔厚度,降低结温至150℃以内。

综上,SS36是一款参数均衡、可靠性高的肖特基二极管,可满足消费电子、工业控制、车载电子等多领域的中小功率整流/续流需求,是低成本、高性能应用的优选器件。

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.
