SS310肖特基二极管产品概述

SS310是扬杰科技(YANGJIE)推出的一款独立式肖特基整流二极管,凭借低正向压降、中等电流能力及紧凑封装,成为消费电子、低压电源等领域的常用器件。以下从核心参数、封装特性、应用场景等维度展开详细说明。

一、产品基本定位

SS310属于低压肖特基整流二极管,核心定位为中低功率(3A级)的整流/续流应用,适配100V以内的反向电压场景。作为独立式器件,无需并联其他元件即可单独工作,简化电路设计,适合批量自动化生产。

二、核心电气参数深度解析

SS310的关键参数直接决定其应用范围,各参数的实际意义及优势如下:

1. 正向压降(Vf):850mV@3A

正向压降是二极管导通时的电压损耗,SS310在额定电流3A下仅为850mV,远低于普通硅整流二极管(典型值1.0V以上)。该特性可显著降低导通损耗,减少器件发热,提升系统整体效率(如开关电源转换效率可提高1%-2%),尤其适合对功耗敏感的便携设备。

2. 直流反向耐压(Vr):100V

反向耐压是二极管可承受的最大反向电压,SS310的100V额定值满足低压直流/交流整流场景(如12V/24V车载系统、低压开关电源次级整流),避免反向击穿风险。

3. 直流整流电流(If):3A

3A的持续整流电流能力,支持中功率负载需求(如5V/3A快充适配器、小型家电电源),且在脉冲电流下仍保持稳定性能,无需额外降额设计即可满足常规应用。

4. 反向漏电流(Ir):100uA@100V

反向漏电流是二极管反向截止时的漏电流,SS310在额定反向电压下仅100uA,属于低漏电流设计。该特性可减少反向功耗,避免器件发热老化,提升系统长期可靠性。

三、封装形式与物理特性

SS310采用SMC(DO-214AB)表面贴装封装,是目前分立器件中常用的紧凑封装之一,具有以下优势:

  • 体积小巧:封装尺寸约为3.5mm×2.5mm×1.1mm,可大幅节省PCB空间,适配高密度电路设计(如小型快充适配器、路由器电源模块);
  • 贴装便捷:符合SMT自动化生产要求,可通过贴片机快速贴装,降低生产人工成本;
  • 散热性能:封装采用高热导材料,配合PCB铜箔可有效散发布尔基效应产生的热量,避免局部过热。

四、典型应用场景

SS310的参数特性使其广泛应用于以下领域:

1. 低压开关电源次级整流

如手机/平板快充适配器(5V/3A)、笔记本电脑电源适配器(次级低压整流),低Vf可提升转换效率,减少适配器发热;

2. DC-DC转换器续流二极管

在12V转5V、24V转12V等降压DC-DC模块中,肖特基二极管的快速恢复特性(肖特基固有优势)可适配高频开关(100kHz-1MHz),提升模块响应速度;

3. 车载低压电路整流

12V/24V车载系统(如车载充电器、行车记录仪电源)的输入整流,100V反向耐压可应对汽车点火时的电压波动(峰值≤80V),3A电流能力满足车载设备负载需求;

4. 小型家电电源整流

如加湿器、路由器、智能音箱等设备的电源输入整流,紧凑封装适配小型化设计,低功耗特性延长设备使用寿命。

五、品牌与可靠性保障

SS310由扬杰科技(国内功率半导体龙头企业)生产,具备以下可靠性优势:

  • 工艺控制:采用成熟的肖特基工艺,严格控制晶圆掺杂、金属接触层等关键环节,确保参数一致性;
  • 测试验证:经过温度循环(-55℃~150℃)、湿度测试(85℃/85%RH)、反向耐压老化等可靠性测试,符合RoHS环保标准;
  • 市场验证:广泛应用于国内主流消费电子厂商,累计出货量超千万级,性能稳定可靠。

综上,SS310以其低功耗、高可靠性、紧凑封装等特点,成为中低功率低压整流/续流场景的高性价比选择。

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.
