SS110肖特基二极管产品概述

一、产品基本定位

SS110是一款独立式肖特基整流二极管,由国产品牌钜兴(JUXING)推出,采用DO-214AC(SMA)表面贴装封装。作为小功率整流/续流核心器件,其核心优势在于低正向压降(VF) 与快速开关特性,兼顾性能、成本与封装密度,广泛适配低压直流电路、开关电源、小型电子设备等场景。

二、核心电气参数详解

SS110的参数针对实用场景优化,关键指标的实际意义需明确:

1. 正向导通特性

  • 正向压降(VF):850mV @ 1A:肖特基二极管的典型低VF特性(远低于普通硅整流管的1V以上),可显著降低导通损耗——以12V系统为例,单管导通损耗比普通管减少约15%,提升电源效率;
  • 持续整流电流(IF):1A(直流):最大持续正向电流,选型时需保留1.2~1.5倍裕量(如实际负载电流≤0.8A),避免过载发热。

2. 反向截止特性

  • 直流反向耐压(VR):100V:可承受的最大反向直流电压,实际应用中需确保电路反向电压(含瞬态尖峰)不超过此值;
  • 反向漏电流(IR):500μA @ 100V:反向工作时的漏电流,处于肖特基二极管的合理范围(比快恢复二极管略高,但不影响小功率场景可靠性)。

3. 瞬态与结温特性

  • 非重复峰值浪涌电流(IFSM):25A:可承受的单次峰值浪涌电流(持续时间≤10ms),适配开机瞬间、负载突变等瞬态冲击;
  • 工作结温范围:-65℃ ~ +150℃:宽温设计,覆盖工业级(-40℃+85℃)与部分汽车级(-55℃+125℃)应用,满足高低温场景需求。

三、封装与物理特性

SS110采用DO-214AC(SMA)表面贴装封装,是小功率二极管的主流封装之一,特点如下:

  • 尺寸紧凑:典型尺寸约2.7mm×1.5mm×1.0mm,适合高密度PCB布局(如智能手机、小型电源模块);
  • 焊接性佳:引脚采用镀锡工艺,兼容回流焊、波峰焊,焊接可靠性高;
  • 绝缘耐温:封装材料为环氧树脂,可承受焊接高温(峰值≤260℃),长期工作无开裂风险。

四、典型应用场景

SS110的低VF、快速开关特性适配多种实用场景:

  1. 开关电源续流:DC-DC变换器(Buck/Boost电路)的续流二极管,低VF减少电源损耗,提升转换效率(如12V转5V电源效率可提升2%~3%);
  2. 低压直流整流:12V/24V电池充电电路、小型适配器的整流桥分支(单管或多管并联);
  3. 反向保护:便携式设备(充电宝、智能手环)的电池反接保护,防止反接损坏电路;
  4. 继电器续流:工业控制电路中继电器线圈的续流二极管,抑制线圈断开时的反向尖峰电压,保护驱动芯片;
  5. 信号钳位:通信设备(路由器、交换机)的信号接口钳位,快速响应瞬态过压,避免芯片损坏。

五、可靠性与环境适应性

SS110通过多项可靠性测试,满足工业级要求:

  • 环境合规:符合RoHS标准(无铅、无镉),适配环保型产品设计;
  • 浪涌耐受:25A非重复浪涌电流可抵御开机、负载突变等冲击,降低失效风险;
  • 长期稳定:反向漏电流稳定(500μA@100V),连续工作1000小时以上无明显参数漂移。

六、选型与使用注意事项

为确保稳定工作,需注意以下要点:

  1. 参数裕量:实际电流≤0.8A、反向电压≤80V,避免过载;
  2. 散热设计:SMA封装散热有限,需在PCB引脚周围铺3~5mm²铜箔,降低结温;
  3. 焊接工艺:回流焊峰值≤260℃(持续≤30s)、波峰焊≤250℃(持续≤5s),防止封装开裂;
  4. 反向保护:若电路存在反向尖峰(如电感电路),需并联压敏电阻/TVS管,避免击穿。

综上,SS110是一款性价比高、适配性强的小功率肖特基二极管,适合对效率、体积有要求的中低端电子设备设计。

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.
