SS10100 产品概述

一、产品简介

SS10100 是 DOWO(东沃)推出的一款高可靠性、低损耗的快恢复/整流二极管,封装为 DO-214AB(SMC)。器件为独立单颗二极管,专为低压高频逆变器和续流(freewheeling)场合设计,兼顾高浪涌承受能力与高速开关特性,适用于对开关损耗和热稳定性有较高要求的电源与电机驱动系统。

二、主要参数

  • 二极管配置:1个独立式
  • 正向压降(Vf):0.95 V @ 10 A
  • 直流反向耐压(Vr):100 V
  • 连续整流电流(Io):10 A
  • 反向电流(Ir):100 µA @ 100 V
  • 工作结温范围(Tj):-55 ℃ ~ +175 ℃
  • 非重复峰值浪涌电流(Ifsm):120 A(单次脉冲条件)
  • 封装:DO-214AB(SMC)
  • 品牌:DOWO(东沃)

三、关键特性

  • 低功耗:在大电流工作时保持较低的正向压降,减小导通损耗,有利于提高系统效率。
  • 极快开关速度:适用于高频开关环境,能有效降低开关过渡损耗和反向恢复引起的电磁干扰。
  • 高正向浪涌能力:Ifsm 达 120 A,能承受启动或短时故障产生的高浪涌电流。
  • 高频操作良好:在开关频率较高的逆变器和开关电源中表现稳定,适合续流回路使用。
  • 宽工作结温:-55 ℃ ~ +175 ℃,提高系统在极端环境下的可靠性与寿命。
  • 保护环设计:内置保护环(guard ring)增强过压与边缘场分布,提升击穿稳健性与可靠性。

四、典型应用

  • 低压高频逆变器和逆变模块的快速整流与续流二极管
  • 电机驱动与变频器的续流/回收回路
  • 开关电源(SMPS)中的输出整流与同步备用件
  • UPS、太阳能逆变器等需承受短时浪涌的电力电子设备

五、封装与热特性

SS10100 采用 DO-214AB(SMC)表面贴装封装,便于自动化贴装与波峰/回流焊接。该封装具有良好的散热面和机械强度,适合较高的稳态电流。实际应用中应注意散热路径设计:保证焊盘良好导热、必要时并联散热片或在 PCB 下方配置散热岛,以便在满载或高环境温度下维持器件结温在安全范围内。

六、安装与使用建议

  • 焊接工艺:遵循 JEDEC/IPC 回流焊温度曲线,避免过高峰值温度和过长保温时间以防损伤器件。
  • 电流降额:在高环境温度或散热不足时,应按厂商电流-温度降额曲线降额使用,避免长期在额定电流边界工作。
  • 浪涌保护:尽管 Ifsm 能承受短时浪涌,仍建议在设计中考虑浪涌限制或适当的软启动电路,避免重复超过峰值浪涌。
  • 反向电压裕量:为保证长期可靠性,实际应用中应留有足够的反向电压裕量,避免长时间接近最大 Vr 工作。

七、可靠性与注意事项

  • 长期在高温、高电压或强振动环境下使用前,应做可靠性验证(热循环、功率循环和电应力测试)。
  • 反向漏电流在高温下会增加,关键应用需关注 Ir 随温度的变化并留有安全裕量。
  • 存储与搬运时防潮防静电,遵循元件防潮等级要求与 ESD 防护规范。

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
