SS310BQ 肖特基整流二极管产品概述

SS310BQ是扬杰科技(YANGJIE)推出的SMB封装肖特基整流二极管,针对中低压、中小功率整流场景优化设计,具备低导通损耗、高可靠性、宽温适应性等核心特点,是工业级、消费电子及汽车辅助电源等领域的高性价比选型。

一、产品核心身份与品牌背景

扬杰科技作为国内功率半导体领域的龙头企业,专注于功率二极管、MOSFET、IGBT等器件的研发与制造,产品覆盖消费电子、工业控制、汽车电子等多领域。SS310BQ是其肖特基整流二极管系列的典型型号,采用表面贴装SMB(DO-214AA)封装,定位为中低压中小功率整流/续流应用的核心器件,可替代进口同类产品(如ON Semiconductor SS310、Toshiba SS310等)。

二、关键电气性能参数解析

SS310BQ的核心参数针对实际应用场景做了针对性优化,关键性能如下:

(1)正向导通特性

  • 额定整流电流(IF):3A(连续直流),满足多数中小功率电源的整流需求;
  • 正向压降(Vf):800mV@3A(测试条件:TA=25℃),远低于普通硅整流二极管(通常≥1V),显著降低导通损耗,提升电源转换效率(尤其适用于低功耗设计)。

(2)反向阻断特性

  • 直流反向耐压(VR):100V,覆盖中低压整流场景(如12V/24V系统的升压后整流);
  • 反向漏电流(Ir):1μA@100V(TA=25℃),漏电流极小,反向阻断可靠性高,减少待机功耗与反向发热。

(3)瞬态与温度特性

  • 非重复峰值浪涌电流(Ifsm):80A(单次,持续时间8.3ms),可承受电路启动、瞬态过流等冲击,提升系统抗干扰能力;
  • 工作结温范围:-55℃~+175℃,宽温特性使其适用于极端环境(如汽车发动机舱、户外工业设备),满足工业级与汽车级部分应用的温度要求。

三、封装与物理特性

SS310BQ采用SMB(DO-214AA)表面贴装封装,具备以下优势:

  • 体积紧凑:典型尺寸为3.5mm(长)×2.5mm(宽)×1.5mm(高),无引脚设计,可显著节省PCB布局空间,适配高密度集成电路;
  • 贴装兼容性:适配自动化SMT生产线,生产效率高,适合批量制造;
  • 环境适应性:封装采用耐高温环氧树脂,具备良好的抗机械应力、防潮、防腐蚀能力,长期工作可靠性高。

四、典型应用场景

结合参数特性,SS310BQ广泛应用于以下领域:

(1)开关电源与适配器

  • AC-DC适配器(手机、笔记本、平板充电器)的次级整流;
  • DC-DC转换器(如Buck/Boost电路)的续流二极管,低压降提升转换效率。

(2)LED驱动电源

  • 小功率至中等功率LED照明(球泡灯、面板灯、路灯)的整流/续流,宽结温适应不同环境温度(如户外照明)。

(3)消费电子与通信设备

  • 机顶盒、路由器、智能家电等设备的电源模块,SMB封装满足小型化设计需求。

(4)工业控制与汽车电子

  • 小型PLC、传感器模块的辅助电源(100V耐压覆盖工业低压场景);
  • 车载充电器、仪表盘辅助电源(宽温特性适配汽车发动机舱环境)。

五、产品优势与选型建议

(1)核心优势

  • 高效节能:低正向压降降低导通损耗,提升电源效率;
  • 高可靠性:小漏电流+宽结温+强浪涌能力,长期工作稳定性好;
  • 小型化设计:SMB封装适配高密度集成;
  • 国产替代:扬杰成熟工艺,成本低于进口同类器件,供应稳定。

(2)选型注意事项

  • 参数降额:实际应用需对IF(降额30%-50%)、VR(降额20%-30%)设计,避免过载;
  • 静电防护:肖特基二极管对静电敏感,生产、存储需采取ESD防护;
  • 散热设计:连续工作时需通过PCB铜箔或散热片控制结温,避免超过175℃上限。

六、总结

SS310BQ作为扬杰科技推出的SMB封装肖特基整流二极管,凭借低损耗、高可靠性、宽温适应性等特点,成为中低压中小功率整流/续流应用的优选器件,可广泛覆盖消费电子、工业控制、汽车电子等领域,是进口同类产品的高性价比国产替代选项。

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
