DSK110 产品概述

一、产品简介

DSK110 是 MDD 品牌推出的一款肖特基整流二极管(独立式封装),采用 SOD123FL 表面贴装封装。该器件设计用于通用整流与开关保护场合,额定直流整流电流为 1A,反向耐压 100V,正向压降在 1A 电流时约为 850mV,适合对开关损耗与正向压降有中等要求的电源与保护电路。

二、主要电气参数

  • 正向压降 (Vf):0.85 V @ IF = 1A
  • 直流反向耐压 (Vr):100 V
  • 平均整流电流 (IF(AV)):1 A(常规整流工作)
  • 反向电流 (Ir):200 μA @ VR = 100 V
  • 工作结温范围:-55 ℃ ~ +150 ℃
  • 配置:独立式(单只封装)
  • 封装:SOD123FL(小型低剖面贴片封装)

三、产品特性与优势

  • 低正向压降:在 1A 工作点 Vf≈0.85V,可在整流和开关应用中减少功率损耗(相较于普通整流二极管更低)。
  • 中等反向耐压:100V 额定值适用于 12V~48V 以及更高工况的电源系统。
  • 稳定的工作温度范围:-55℃ ~ +150℃,适用于宽温环境的工业与汽车电子(请按具体应用做热设计)。
  • 紧凑封装:SOD123FL 占板面积小,适合高密度 PCB 布局,良好的焊接可靠性与制造兼容性。

四、典型应用场景

  • 开关电源(SMPS)次级整流
  • DC-DC 转换器、同步整流替代
  • 续流/回流保护(free-wheeling)
  • 电池充放电与保护电路
  • 逆接保护与二极管 OR-ing
  • LED 驱动与一般整流场合

五、设计与使用建议

  • 热管理:虽然 SOD123FL 有一定散热能力,但在接近 1A 连续工作时建议留足铜面或加热沉(在焊盘处铺设散热铜或通孔)。考虑按功率损耗 P = Vf × IF 估算结温并做适当降额。
  • 反向泄漏:在高温或高电压条件下,Ir(200 μA @100V)会增加,若电路对漏电敏感(如高阻输入或电池系统),应评估是否需要更低漏电规格器件或并联/屏蔽处理。
  • 开关冲击:肖特基二极管反向恢复时间短,但仍建议在高 dv/dt 场合加合适的限流或阻尼元件以抑制瞬态尖峰。
  • PCB 布局:走线尽量短且宽,阳极/阴极焊盘分散热面积,避免热集中。关键回路附近保持足够的地/电源回流路径。
  • 焊接与可靠性:按常规回流焊工艺处理,避免超出器件最高结温,存储与回流前注意防潮处理(若为高湿敏等级)。

六、注意事项与资料索取

  • 本概述基于典型参数,具体极限值、热阻、脉冲电流规格、封装尺寸与焊盘推荐请参照 MDD 官方数据手册。
  • 在关键或苛刻应用(高温、高压脉冲或安全相关电路)中,建议做样机测试与长时可靠性评估。
  • 如需完整规格书、封装图、推荐焊盘或样品支持,请联系 MDD 厂家或经销商索取 DSK110 数据手册与技术支持。

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
