DS110W 产品概述

一、产品简介

DS110W 是 BLUE ROCKET 提供的一款独立式整流二极管,采用 SOD-123FL 小型贴片封装,面向空间受限的电源和保护电路设计。器件额定直流整流电流为 1A,适合中低功率的整流与保护场合;非重复峰值浪涌电流 Ifsm 为 30A,具备较好的浪涌承受能力。工作结温范围为 -55℃ 至 +125℃,可满足一般工业和民用环境温度要求。

二、主要电气参数

  • 正向压降 (Vf):850 mV @ 1 A — 在 1A 工作电流下典型正向压降约 0.85V,属于常规硅整流二极管水平。
  • 直流反向耐压 (Vr):100 V — 可用于 100V 及以下的整流与阻断场景。
  • 反向电流 (Ir):200 μA @ 100 V — 在接近额定耐压时有一定反向漏流,应在高阻抗或高精度测量电路中谨慎使用。
  • 整流电流:1 A 连续 — 适合持续工作电流不超过 1A 的电路。
  • 非重复峰值浪涌电流 Ifsm:30 A — 在瞬态冲击或启动浪涌时具备较好的吸收能力。

以上参数为器件选型的关键参考,具体应用时请结合实际工作温度和散热条件核对。

三、封装与热性能

SOD-123FL 为小型扁平贴片封装,优点是体积小、适合高密度安装;但相对热阻较大,热量主要通过焊盘和 PCB 散发。由于器件连续电流为 1A,建议在 PCB 设计时为二极管周围留出适当的铜面积或添加热沉通道,以降低结温上升,保证长期可靠性。SOD-123FL 也适合自动贴装及回流焊工艺,具体焊接工艺请参照封装厂商的回流规范。

四、典型应用场景

  • 开关电源的次级整流(低功率模块)
  • 电源反接保护与极性保护
  • 二极管 steering、耗散路径或钳位电路
  • 通用整流与续流场合(非高精度低漏流要求)
  • LED 驱动(小功率)、电池充放电路径保护等

需注意:在要求非常低正向压降或极低反向漏电的场合,DS110W 的 Vf 与 Ir 特性可能不是最优选择。

五、设计与布局建议

  • PCB 布局:为二极管焊盘增加散热铜箔,必要时在焊盘下方采用过孔连接底层散热层,减小结温。
  • 过流/浪涌保护:尽管 Ifsm 达 30A,但该值为非重复峰值浪涌能力,不能作为长期过载使用依据。设计中应考虑熔断器或限流电路保护。
  • 漏电考量:在高阻抗检测或漏电敏感电路中,100V 时 200 μA 的反向漏流可能影响测量,应在选型时评估。
  • 焊接工艺:采用标准回流焊流程,遵循 SOD-123FL 的热循环限制,避免重复高温导致封装应力。

六、可靠性与注意事项

  • 温度范围:-55℃ 至 +125℃ 的结温范围覆盖多数工业与民用应用,但长期在高温接近上限工作将影响器件寿命,建议控制结温在安全裕度内。
  • 包装与手册:具体引脚标识、封装外形尺寸和回流曲线请参阅厂商完整数据手册与包装说明,用于精确的 PCB 焊盘设计与制造流程验证。
  • 应用局限:若系统对效率、热耗或低漏电有严格要求,可考虑低 Vf 或肖特基型号替代;若需要更高耐压或更大连续电流,应选用相应规格器件。

七、总结

DS110W 是一款面向通用整流和保护应用的 1A SOD-123FL 封装二极管,具备 100V 耐压、0.85V 正向压降(1A)及 30A 瞬态浪涌承受能力。适合体积受限且对中等功率整流有需求的设计,但在高精度、低漏电或超高效能场合需慎重评估。建议在最终设计中结合实际热设计与电路保护方案,确保器件在安全工况下长期稳定工作。

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.
