S1J 产品概述

S1J 为 TWGMC(台湾迪嘉)提供的一款通用整流二极管,采用独立式 SMA(DO-214AC)封装,面向开关电源、适配器、整流与保护电路等常规功率整流应用。器件具有较高的反向耐压与良好的浪涌承受能力,适合在苛刻环境下作为经济可靠的整流与保护元件使用。

一、主要规格

  • 类型:通用整流二极管(独立式,单只)
  • 封装:SMA(DO-214AC)
  • 最大重复峰值逆向电压 (Vr):600 V
  • 正向电流(连续整流):1 A
  • 正向压降 (Vf):典型 1.1 V @ IF = 1 A
  • 非重复峰值浪涌电流 (Ifsm):30 A(脉冲,单次)
  • 反向漏电流 (Ir):典型 5 μA(在额定 Vr 下)
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 品牌:TWGMC(台湾迪嘉)

二、产品特性

  • 高耐压:600 V 逆向耐压,适用于中高压整流场合。
  • 低正向压降:1 A 工作点下正向压降约 1.1 V,有助于降低导通损耗与发热。
  • 良好的浪涌能力:30 A 非重复峰值浪涌电流,可应对开机或短时过载脉冲。
  • 宽温度工作范围:-55 ℃ 至 150 ℃,适应工业级温度环境。
  • 小尺寸表面贴装封装(SMA),利于自动化贴装与节省 PCB 面积。

三、典型应用场景

  • 开关电源二次整流与续流路径
  • 线性电源、适配器与充电器的整流与保护
  • 极性保护、反接防护电路
  • 电机驱动、继电器回路的续流与抑制
  • 工业电源、照明与电源模块的通用整流需求

四、封装与热管理

SMA(DO-214AC)封装在表面贴装平台上具有良好的机械强度与散热通道。尽管器件正向电流标称为 1 A,但在实际电路设计中需考虑结温上升和散热条件,建议:

  • 在 PCB 设计时为二极管散热增加铜箔面积(导热垫或散热岛),并考虑热环流通路径以降低结温;
  • 在高占空比或连续大电流工作条件下,按实际结温计算允许连续电流并进行必要的热降额;
  • 浪涌脉冲(Ifsm)为非重复峰值能力,不可作为长期过载使用依据。

五、使用建议与可靠性

  • 反向漏电流会随温度显著上升,长期高温工作会增加漏电并影响性能,必要时在规格边界上留裕量;
  • 在并联使用多只二极管时需确保电流均分(通常不推荐并联用于功率扩展,若必须并联需加阻阻止不均流);
  • 建议遵守制造商提供的回流/波峰焊工艺规范,避免超出最大回流温度或时间;若使用无铅工艺,请参照相应的温度曲线;
  • 存储与工作环境应避免潮湿、高腐蚀性气氛与机械冲击。

六、示例电路与注意事项

  • 作为输出整流:S1J 可作为整流桥单元的单个二极管或作为单相整流二极管使用,注意反向峰值电压应大于电路中可能出现的最大反向电压。
  • 作为续流二极管:在开关器件关断时承受较大反向电压与脉冲电流,需校验 Ifsm 与能量吸收能力;若连续高频或大电流续流场景建议选择肖特基或快恢复类型以降低损耗。
  • 极性标记:器件一端带有阴极标识(通常为带状标记),安装时注意方向。

七、包装与订购信息

  • 封装形式:SMA 单只独立式(托盘或卷带视供应商版本)
  • 标记:常见型号标注为“S1J”或厂商代码,具体外观与标记以实物与包装为准
  • 订购建议:按需留出温度与电流裕量;若用于关键电源或高频大电流场合,建议样品评估并与厂商确认详细电气热参数与可靠性数据。

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
