SM1100A 产品概述

一、产品简介

SM1100A 是乐山无线电(LRC)推出的一款独立式肖特基二极管,采用 DO-214AC(SMA)封装,专为中小功率整流和保护场合设计。器件以肖特基势垒为基础,响应速度快、损耗低,适用于工业与消费类电源应用。

二、主要参数

  • 型号:SM1100A
  • 品牌:LRC(乐山无线电)
  • 封装:DO-214AC(SMA),表面贴装独立器件
  • 正向压降(Vf):0.85 V(典型值,通常在 1 A 条件下测得,测量条件请参见厂方资料)
  • 直流反向耐压(Vr):100 V(最大额定反向电压)
  • 整流电流(IF):1 A(平均整流电流)
  • 工作结温范围:-40 ℃ ~ +150 ℃

三、特性与优势

  • 低正向压降:在额定电流下具有较低的压降,有助于降低整流损耗与温升。
  • 快速响应:肖特基结构使器件无恢复时间,适合开关电源和高频整流。
  • 宽温度工作区:-40 ℃ 到 +150 ℃ 的结温范围,满足多种工业工作环境。
  • 可靠封装:DO-214AC(SMA)提供良好的机械强度与热传导性能,便于自动贴装与回流工艺。

四、典型应用

  • 开关电源输出整流与续流;
  • 二极管保护(反向极性保护、浪涌钳位);
  • 直流-直流转换器、汽车电子(在额定参数内使用);
  • 电池充放电管理、电源模块的效率优化场合。

五、封装与热管理

DO-214AC(SMA)封装在保证机械强度的同时,具有相对较好的散热能力。建议设计时:

  • 在焊盘处保留足够的铜箔面积以增强散热;
  • 对于较高的功耗工况,采用多层板与过孔通热处理以降低结-环境温升;
  • 尽量缩短电流回路长度,减小寄生电感与发热集中。

六、安装与可靠性建议

  • 遵循厂方的焊接温度曲线与回流工艺规范,避免过高的峰值温度与重复加热;
  • 储存与装配应避免潮湿与机械冲击,必要时依据湿敏等级(MSL)采取干燥措施;
  • 设计中预留适当电流裕量与热裕度,以保证长期稳定性与寿命。

七、订购信息与资料获取

订购时请指明型号 SM1100A、品牌 LRC、封装 DO-214AC(SMA)。如需详细的电气特性曲线、温升测试、封装尺寸与焊接规范,请联系乐山无线电或参考其最新数据手册,以获得完整的参数与应用指导。

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
