S-SM2100B肖特基二极管产品概述

S-SM2100B是乐山无线电(LRC)推出的一款SMB封装(DO-214AA)肖特基二极管,针对中功率整流、续流及瞬态防护场景优化设计,凭借低正向压降、高浪涌耐受能力与宽温度适应性,成为消费电子、工业控制等领域的高性价比器件选择。

一、核心参数概览

该器件关键性能参数明确,可覆盖多数常规应用需求:

  • 正向压降(Vf):850mV(典型值),远低于普通硅整流二极管(通常1V以上),导通损耗显著降低;
  • 直流反向耐压(Vr):100V,满足低压整流电路的反向耐压要求;
  • 整流电流(IF):2A(直流),支持中功率负载的持续工作;
  • 反向漏电流(Ir):1uA(典型值),反向功耗极小,提升电路稳定性;
  • 非重复峰值浪涌电流(Ifsm):60A(8.3ms正弦波),可有效应对电路瞬态脉冲冲击;
  • 工作结温范围:-50℃~+150℃,适应极端高低温环境。

二、产品关键特性

  1. 低导通损耗:850mV的正向压降是核心优势,在低压整流场景(如5V/12V电源)中,可减少发热、提升效率,尤其适合小型化无散热设计;
  2. 强浪涌耐受:60A的非重复浪涌电流能力,可抵御电源启动、负载突变等瞬态脉冲,降低器件损坏风险;
  3. 低漏电流:1uA反向漏电流,避免反向导通时的额外功耗,提升电路可靠性;
  4. 宽温适应性:-50℃至+150℃的结温范围,覆盖工业级环境(如户外设备、车载辅助电路)与消费电子的极端温度场景;
  5. 紧凑封装适配:SMB(DO-214AA)表面贴装封装,尺寸小巧(约4.5×3.5×2.0mm),支持自动化贴装,适合高密度PCB设计。

三、封装与品牌背景

  • 封装细节:SMB封装采用表面贴装结构,引脚间距合理,散热路径清晰,可通过PCB铜箔辅助散热,满足2A电流的持续工作需求;
  • 品牌保障:乐山无线电(LRC)是国内老牌半导体厂商,专注功率器件研发数十年,产品符合RoHS无铅无卤标准,可靠性经市场验证,广泛应用于家电、通信、工业等领域。

四、典型应用场景

S-SM2100B的性能适配多类电路,常见应用包括:

  1. 开关电源整流:如手机充电器、LED驱动电源的低压整流级(替代传统硅二极管,提升效率);
  2. 续流二极管:电机驱动、电感电路的续流保护(肖特基二极管恢复速度快,可快速关断反向电流);
  3. 瞬态防护辅助:配合TVS管使用,应对电源浪涌(浪涌电流能力可缓冲脉冲冲击);
  4. 消费电子电路:小型家电(如加湿器、台灯)的电源整流,低发热提升产品体验;
  5. 工业控制电路:PLC、传感器模块的低压供电整流,宽温范围适应工业现场环境。

五、可靠性与环境适应性

该器件通过多项可靠性测试,确保长期稳定工作:

  • 反向耐压测试:100V直流反向耐压符合IEC标准,避免过压击穿;
  • 浪涌测试:60A/8.3ms浪涌脉冲测试通过JESD22-A108标准,抵御瞬态冲击;
  • 温度循环测试:-50℃~+150℃循环1000次无失效,适应极端环境;
  • 无铅工艺:符合RoHS 2.0标准,环保且兼容现代贴装工艺。

总结

S-SM2100B作为LRC推出的SMB封装肖特基二极管,以低Vf、高浪涌、宽温区为核心优势,覆盖消费电子、工业控制等多领域应用,兼具高性价比与可靠性,是替代传统硅整流二极管的理想选择,适合对效率、体积有要求的电路设计。

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
