SM3200A整流二极管产品概述

一、产品定位与核心特性

SM3200A是乐山无线电(LRC)推出的通用型表面贴装整流二极管,主打中低压、中小功率应用场景,核心特性聚焦“高效导通、高可靠性、宽温适配”,通过紧凑的SMA封装实现性能与空间的平衡,满足消费电子、工业控制等领域的整流需求。

二、关键电气参数深度解析

SM3200A的参数设计针对典型应用场景做了针对性优化,核心参数及意义如下:

  1. 正向压降(Vf):[email protected]
    低正向压降是其核心优势——额定连续电流3A下,导通损耗仅约2.61W(P=Vf×If),显著低于传统硅整流二极管(通常Vf≥1V@3A),可有效提升电源转换效率,降低散热需求。
  2. 直流反向耐压(Vr):200V
    200V反向耐压覆盖多数低压应用(如110V交流整流峰值≈155V、12V-48V直流系统反向防护),避免反向过压导致的器件失效。
  3. 连续整流电流(If):3A
    额定连续电流3A,可稳定承载中小功率电源的输出/输入整流(非市电全波整流,需匹配耐压),满足单路3A以内的负载需求。
  4. 反向漏电流(Ir):500μA@200V
    反向漏电流控制在500μA以内,远低于行业平均水平,长期工作漏电流损耗低,反向绝缘性可靠,减少发热与失效风险。
  5. 工作结温范围:-40℃~+150℃
    宽温设计适配高低温环境(如汽车舱内、户外小型设备),无需额外温度补偿电路,降低系统复杂度。
  6. 非重复峰值浪涌电流(Ifsm):80A
    80A浪涌能力可承受启动瞬间、负载突变等大电流冲击(如电容充电浪涌),提升系统抗过载能力,减少器件损坏。

三、封装与可靠性设计

SM3200A采用SMA表面贴装封装(行业标准尺寸:约2.9mm×5.0mm×1.1mm),具备以下优势:

  • 贴装兼容性:支持自动化SMT贴装,适合大规模量产,节省PCB布局空间;
  • 热学性能:封装引脚与散热路径优化,可快速将结温传导至PCB,配合合理散热设计满足结温要求;
  • 可靠性保障:采用LRC成熟芯片工艺,经高温老化、浪涌测试、温度循环等验证,批量一致性达行业领先。

四、品牌与品质背书

SM3200A由国内半导体龙头乐山无线电(LRC) 生产,LRC拥有超50年分立器件制造经验,产品符合RoHS环保标准,通过ISO9001、IATF16949等认证,广泛应用于国内外知名家电、电源厂商,品质稳定性经市场验证。

五、典型应用场景

结合参数特性,SM3200A适用于以下场景:

  1. 消费电子电源:手机/平板充电器(5V/3A)、笔记本适配器(19V/2.3A)的输出/辅助电源整流;
  2. LED驱动电源:小功率LED路灯、室内照明驱动的整流桥(单管并联可提升电流);
  3. 工业控制模块:PLC、传感器模块的低压直流电源整流、反向防护;
  4. 汽车电子辅助电路:车载USB充电、仪表盘电源的整流(适配-40℃~85℃环境);
  5. 小型家电控制板:豆浆机、加湿器等的电源整流电路。

总结:SM3200A以“低导通损耗、高可靠性、紧凑封装”为核心竞争力,是中小功率整流场景的高性价比选择,尤其适合对效率、抗浪涌及宽温性能有要求的应用。

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
