SS26肖特基整流二极管产品概述

一、产品基本信息与定位

SS26是富信(FOSAN)品牌推出的SMA封装肖特基整流二极管,属于中低压、中小功率整流器件范畴。该器件以低正向压降、宽温适应性为核心特点,适配多种需要高效整流、续流的电子电路场景,是消费电子、电源领域的常用基础器件。

二、核心电性能参数详解

SS26的电性能参数精准匹配应用需求,关键指标如下:

  1. 正向压降(Vf):700mV(@2A直流电流)—— 肖特基二极管典型低损耗特性,相比普通硅整流管(如1N4007的Vf≈1V@1A)显著降低导通损耗,提升电路效率;
  2. 直流反向耐压(Vr):60V—— 满足多数低压电路的反向电压耐受需求,避免电路反向偏置时击穿;
  3. 持续整流电流(IF):2A—— 可稳定承载2A直流电流,支持中小功率设备的持续工作;
  4. 反向漏电流(Ir):100μA(@60V反向电压)—— 低漏损特性,减少待机状态下的功耗浪费;
  5. 非重复峰值浪涌电流(Ifsm):50A—— 单次突发电流冲击能力强,可应对电路启动、负载突变等场景的浪涌;
  6. 工作结温范围:-65℃~+150℃—— 宽温度适应性,可在极端低温(如户外低温环境)或高温(如电源内部发热环境)下稳定工作。

三、封装与物理特性

SS26采用SMA封装(DO-214AC),是一种贴片式小型封装,具有以下优势:

  • 尺寸紧凑:典型封装尺寸约2.4mm(宽)×5.8mm(长)×1.2mm(高),大幅节省PCB空间,适配小型化电子设备;
  • 自动化兼容:贴片封装支持高速SMT生产,降低组装成本;
  • 散热优化:封装结构利于热量传导,配合合理PCB布线可有效散发热量,保障结温不超过上限。

四、典型应用场景

SS26的参数特性使其适用于以下常见场景:

  1. 开关电源次级整流:如5V/12V输出的手机充电器、LED驱动电源,利用低Vf特性降低整流损耗,提升电源效率;
  2. 续流二极管:电机驱动电路、继电器线圈电路中,防止线圈断电时产生的反向电动势击穿其他器件;
  3. DC-DC转换器:降压(Buck)或升压(Boost)电路的整流环节,适配小功率(<2A)的电压转换需求;
  4. 消费电子辅助电路:充电宝、智能手表、蓝牙耳机等设备的电源管理模块;
  5. 汽车电子辅助电路:车载充电器、仪表盘电源等对宽温范围有要求的场景。

五、产品优势总结

相比同规格普通硅整流管,SS26具有明显优势:

  • 高效节能:低正向压降减少导通损耗,适合对效率要求较高的电源电路;
  • 低功耗待机:低反向漏电流降低待机状态下的能量消耗;
  • 可靠性高:宽结温范围+抗浪涌能力,适应复杂工作环境,减少器件损坏概率;
  • 小型化适配:SMA封装满足电子设备轻薄化趋势。

六、选型与使用注意事项

  1. 电压降额:实际电路中反向电压应不超过60V(直流),建议留10%-20%裕量,避免过压损坏;
  2. 电流降额:持续工作电流建议不超过1.8A(留10%裕量),防止过热导致结温超限;
  3. 散热设计:若工作在高电流、高温环境,需优化PCB布线(如增加焊盘散热面积),必要时配合散热片;
  4. 浪涌防护:非重复浪涌电流50A为单次冲击值,多次冲击需降额使用,或配合TVS管等浪涌防护器件。

SS26作为一款高性价比的肖特基整流二极管,凭借平衡的性能参数与紧凑封装,成为中小功率电子电路的优选器件之一,广泛应用于消费电子、电源、汽车电子等领域。

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
