RBR3LAM60ATR 肖特基整流二极管产品概述

RBR3LAM60ATR是罗姆(ROHM)推出的表面贴装型肖特基整流二极管,针对中低压、中等电流场景优化设计,平衡了正向压降、反向耐压与电流容量,广泛适配消费电子、工业控制、汽车电子辅助系统等领域的高效电源与信号处理需求。

一、核心电气参数解析

作为肖特基二极管,RBR3LAM60ATR的关键参数突出“低损耗、高可靠性”导向:

  1. 正向压降(Vf):660mV@3A——相比普通硅整流二极管(典型Vf≥1V@3A),低Vf可显著降低导通损耗,提升电源转换效率,尤其适合DC-DC电路、LED驱动等高效能场景。
  2. 直流反向耐压(Vr):60V——满足12V/24V等主流低压电源架构的反向耐压需求,避免电路反向偏置时的击穿风险。
  3. 整流电流(If):3A(直流)——持续工作电流达3A,峰值电流典型值≥6A,覆盖中等功率应用的电流需求。
  4. 反向电流(Ir):100uA@60V——反向漏电流极低,待机或低负载状态下减少功耗,延长电池供电设备续航,同时提升电路稳定性。

二、封装与物理特性

该器件采用SOD-128表面贴装封装,具备三大优势:

  • 紧凑尺寸:典型封装尺寸约2.7mm(长)×1.6mm(宽)×1.0mm(高),适配高密度PCB设计,可缩小智能手机、小型工业模块等终端产品体积。
  • 散热性能:罗姆优化热传导路径,SOD-128热阻(RθJA)约50℃/W,满足3A电流下的散热需求,避免热积累导致性能下降。
  • 工艺兼容性:符合回流焊标准,引脚强度高,可承受多次焊接循环,适配自动化生产流程。

三、性能优势与适用场景

RBR3LAM60ATR的设计特性使其在多场景具备竞争力:

  1. 高效电源转换:低Vf+低Ir组合可将DC-DC降压转换器效率提升3%-5%(如12V转5V/3A电路),减少电源模块发热与功耗。
  2. 空间受限应用:SOD-128小封装适配智能手机充电电路、汽车传感器模块(胎压监测、座椅控制)等空间紧张场景。
  3. 电池供电设备:低反向漏电流降低待机功耗,延长智能穿戴、便携式医疗设备续航时间。
  4. 工业控制电路:60V耐压+罗姆典型工业级温度范围(-55℃~150℃),适配PLC模块电源整流、信号钳位等恶劣环境场景。

四、可靠性与环保合规

罗姆通过多项测试保障该器件可靠性:

  • 反向耐压稳定性:采用玻璃钝化芯片工艺,提升反向电压下的性能一致性,避免长期使用参数漂移。
  • 环境适应性:符合RoHS、REACH环保标准,无铅封装适配绿色制造;宽温范围(-55℃~150℃)满足工业级环境需求。
  • 抗浪涌能力:具备瞬态过流耐受能力,应对电路浪涌冲击,提升终端产品抗干扰性。

五、典型应用电路参考

  1. DC-DC降压续流:12V转5V/3A降压电路中,作为续流管减少压降损失,效率提升至90%以上。
  2. LED驱动整流:3串LED(每串12V)整流电路中,60V耐压覆盖反向电压,3A电流适配中等功率LED阵列(台灯、背光)。
  3. 消费电子电源路径:智能手机USB充电电路中,作为电源路径整流二极管,小封装适配主板高密度设计。
  4. 工业信号钳位:PLC输入输出模块中,抑制瞬态过压,保护敏感元件。

综上,RBR3LAM60ATR凭借低损耗、小封装、高可靠性,成为中低压中等电流场景下肖特基二极管的优选方案,适配多领域终端产品的高效、小型化需求。

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
