SS16HE(DOWO 東沃)产品概述

一、产品简介

SS16HE 是 DOWO(东沃)推出的一款肖特基势垒二极管,额定反向耐压 60V、连续整流电流 1A,采用 SOD-123HE 表面贴装封装。该器件结合肖特基二极管固有的低正向压降与快速恢复特性,适合各类功率整流、续流保护与电源管理场合,尤其在空间受限的 SMD 应用中表现出色。

二、主要参数

  • 型号:SS16HE(DOWO / 东沃)
  • 封装:SOD-123HE(表面贴装)
  • 正向压降:Vf = 700 mV @ IF = 1.0 A
  • 直流反向耐压:Vr = 60 V
  • 连续整流电流:IF = 1 A
  • 反向漏电流:Ir = 500 μA @ Vr = 60 V
  • 非重复峰值浪涌电流:Ifsm = 30 A(单次峰值)
  • 工作结温范围:Tj = -55 ℃ ~ +175 ℃

三、关键特性

  • 低正向压降:在 1A 工作点上 Vf≈0.7V,有利于降低整流与保护电路的能量损耗。
  • 低反向恢复与快速响应:肖特基结构使器件在开关与续流场合产生较小的开关损耗。
  • 宽温度适应性:-55℃ 至 +175℃ 的结温范围,适合工业级与高温环境应用。
  • 良好的浪涌承受能力:30A 的非重复峰值浪涌电流,能承受短时启动/冲击电流。
  • 紧凑封装:SOD-123HE 适合高密度 PCB 布局和自动化贴装。

四、典型应用

  • 开关电源整流与续流二极管(降压、升压、反激等拓扑)
  • 充电器、适配器与电源模块的输出整流与保护
  • 逆接保护与防反接开关应用
  • 汽车电子中非敏感信号与电源路径(需考虑高温下漏电流上升)
  • 太阳能逆变器、小功率电源与消费类电子电路

五、设计与装配建议

  • 散热设计:SOD-123HE 为小型封装,热阻相对较大。建议在 PCB 板上增加铜箔面积并做热流通道,必要时通过过孔将热量传导到内层或底层散热区。
  • 电流与温度考虑:在靠近额定电流工作或高环境温度下,应适当降额使用,注意漏电流随温度上升而增加,可能影响高阻抗或待机电路。
  • 浪涌能力:30A Ifsm 为非重复峰值,适用于短时冲击,应避免反复超出额定导致封装或结温损伤。
  • 焊接工艺:遵循器件的回流焊工艺规范和潮湿敏感度等级(MSL)要求,常规无铅回流峰值温度范围可参考行业通用曲线,避免超过器件极限温度。
  • PCB 封装与焊盘:遵循 SOD-123HE 的推荐焊盘尺寸与焊膏量,保证焊点可靠性与热传导。

六、可靠性与存储

  • 储存与防潮:建议按厂家出货包装和防潮要求储存,长期暴露会影响可焊性与可靠性。
  • 可靠性测试:适合做高低温循环、热冲击与浪涌测试验证,确认在目标应用的寿命要求下满足性能稳定性。
  • 安全选型提示:若电路对漏电流极为敏感,或需在更高电压/更大电流场合工作,可选择更高耐压或更低漏电规格的替代型号。

总结:SS16HE 为一款兼具低压降、快速响应与宽工作温度的 60V/1A 肖特基二极管,SOD-123HE 封装适合空间受限的表贴电源与保护电路。设计时需关注散热与温度对漏电流的影响,合理降额与 PCB 热管理可确保长期稳定运行。若需器件数据手册、封装图或回流曲线,请参考 DOWO 官方资料以获取完整规范。

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
