TWGMC SB10100L 产品概述

一、产品简介

TWGMC(台湾迪嘉)SB10100L 是一款独立式肖特基/整流二极管,封装为 TO-277,面向中功率整流与保护应用。器件额定整流电流为 10A,直流反向耐压 100V,适合用于需要较大电流且要求低正向压降的电源前端与输出整流场合。

二、主要电气参数

  • 二极管类型:独立式整流/肖特基(SB 前缀常用于肖特基整流器件)
  • 额定整流电流(IF):10A
  • 典型正向压降(Vf):0.75V @ 10A(在额定电流下的典型能量损耗指标)
  • 直流反向耐压(Vr):100V
  • 反向电流(Ir):300µA(典型值,通常在指定 Vr 和环境温度下测量)
  • 工作结温范围:-55℃ ~ +150℃

根据 Vf 与 IF,可估算在 10A 连续工作时的正向损耗约为 7.5W(P = Vf × IF),这对散热设计提出了明确要求。

三、热特性与散热设计

TO-277 封装针对功率器件提供良好的散热基底,实际应用中仍需考虑下列要点:

  • 连续 10A 工作时产生较高的功耗(约 7.5W),建议采用合适的散热片或将器件固接至具散热能力的金属面/散热结构。
  • 反向漏流会随温度显著上升,高温时 Ir 可增大,应在系统热预算中予以考虑。
  • 工作结温应严格控制在额定范围内,长时间接近上限会影响可靠性与寿命。具体热阻与散热方案请参见厂方数据手册。

四、典型应用场景

  • 开关电源输出整流、整流桥替代件(并联或单独使用以提升电流)
  • DC-DC 转换器输出侧整流与自由轮回路
  • 反向保护、OR-ing 电路(并联用于冗余与电流分享时需注意均流)
  • 充电器与电源管理模块中需要 100V 级耐压与 10A 整流能力的场合

五、封装与安装建议

  • 封装:TO-277,适合通过机械固定与散热片接触进行散热。具体引脚排列、安装孔位与外形尺寸请以产品数据手册为准。
  • 焊接与装配:推荐采用良好导热的螺栓固定或导热垫紧密接触散热器,避免直接在高温环境下进行长时间回流焊接,防止封装材料应力。
  • PCB布局:若直接焊接于 PCB,需保证铜箔面积与散热过孔足够,以降低结壳温差。

六、可靠性与注意事项

  • 反向电流随温度上升,系统需对高温条件下的漏电及功耗进行评估。
  • 若用于并联以增加电流容量,应采用电阻或热耦合等方式保证均流,避免单管过载。
  • 在脉冲或高浪涌条件下,应评估瞬态功耗与单脉冲额定值,必要时配合浪涌抑制器件使用。
  • 出于安全与一致性考虑,具体设计前建议参考并遵循 TWGMC 官方数据手册与可靠性测试报告。

七、订购信息与标识

  • 型号:SB10100L
  • 品牌:TWGMC(台湾迪嘉)
  • 封装:TO-277
  • 在采购与替换时,请核对完整的规格书、封装图与测试条件,确保 Vf、Ir 的测试条件与系统要求一致,以避免选型误差。

如需更详细的温度特性曲线、结壳热阻、极限脉冲数据与封装尺寸,请向供应商索取完整数据手册以便做精确的热与电气设计。

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
