SS26F 产品概述

一、概述

SS26F 是 UMW(友台半导体)推出的一款通用肖特基/快速恢复二极管,适用于中等功率整流与保护场合。该器件在2A工作电流条件下正向压降仅约0.7V,反向耐压达60V,兼具较低的导通损耗与良好的浪涌承受能力,适合开关电源、整流桥、电池保护及反向防护等通用场合。

二、主要参数

  • 正向压降 (Vf):700 mV @ 2A
  • 直流反向耐压 (Vr):60 V
  • 最大整流电流:2 A
  • 反向漏电流 (Ir):500 μA @ 60 V
  • 非重复峰值浪涌电流 (Ifsm):50 A(脉冲、短时)
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 封装:SMAF(表面贴装)

(以上参数以典型/额定测试条件为准,设计时应参考完整数据手册以获取温度、电流波形等对应的极限值与曲线。)

三、特性与优势

  • 低正向压降:在2A工作点时约0.7V,减小导通损耗与发热,有利于提高效率。
  • 良好浪涌能力:50A 非重复峰值脉冲浪涌容许短时承受大电流冲击,适合瞬态冲击较大的电路。
  • 宽温度范围:-55℃至+150℃的工作结温,适应工业级环境。
  • 通用封装:SMAF 封装兼容常规SMT工艺,便于自动贴装与回流焊接。

四、封装与安装要点

  • SMAF 表面贴装,建议按制造商推荐的PCB焊盘尺寸设计以保证热阻最低、焊点可靠。
  • 回流焊接兼容性良好,焊接温度曲线应遵循标准回流工艺,避免超过封装允许的峰值温度和时间。
  • 为降低结温并提升可靠性,在PCB布局中应提供适当的散热铜箔并增大焊盘面积,必要时配合热 vias 引下散热。

五、典型应用

  • 开关电源整流与续流二极管
  • 电池充放电保护与反向防护
  • 适配器与充电器输出整流
  • 继电器与电机驱动回路的自由轮回路
  • 通用电源管理与浪涌抑制电路

六、热管理与可靠性提示

  • 在高环境温度或连续2A工作条件下需关注结-壳及结-环境热阻,必要时进行电流降额或增加散热。
  • 反向漏电流会随温度上升明显增加,长期高温下务必验证系统漏电接受度。
  • Ifsm 为非重复峰值浪涌电流,仅限短时脉冲,不能作为重复或持续电流使用依据;设计时应考虑浪涌能量和脉冲宽度。

七、选型与使用建议

  • 若关注更低正向压降或更小反向漏电,可参考同类系列中规格更优的型号;若工作电压超出60V,请选择更高Vr等级的器件。
  • 系统级设计时,务必核对数据手册中的电气特性曲线、热阻与封装机械图以确保可靠性。
  • 对于关键应用,建议进行整板温升与浪涌试验验证,确认在实际工作工况下的性能与寿命。

以上为 SS26F 的关键性能与应用要点,更多详细特性(如电气特性曲线、封装尺寸、典型波形、可靠性测试数据)请参阅 UMW 官方数据手册以获得完整规范与额定条件。

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
