LBAW56WT1G 产品概述

一、产品简介

LBAW56WT1G 是一款为高速开关与小信号整流设计的双二极管器件,采用 1 对共阴极(common‑cathode)结构,单芯片内集成两颗二极管,封装为 SOT‑323,品牌为 LRC(乐山无线电)。器件特点为正向压降低、恢复时间短、反向漏电小,适合移动终端、开关电源和高速逻辑接口等场合。

二、主要电气参数

  • 二极管配置:1 对共阴极(双二极管)
  • 正向压降(Vf):典型 1.25 V(在规定的测试电流下)
  • 直流反向耐压(Vr):70 V(器件耐压等级)
  • 直流正向电流(If):200 mA(连续工作)
  • 非重复峰值浪涌电流(Ifsm):500 mA(脉冲)
  • 反向电流(Ir):典型 2.5 μA(在 Vr 下)
  • 反向恢复时间(Trr):典型 6 ns(高速开关特性)
  • 工作结温范围(Tj):−55 ℃ ~ +150 ℃

以上为本型号的典型与代表性参数,具体测试条件(如温度、脉冲宽度、测量电流)以器件数据表为准。

三、封装与热特性

LBAW56WT1G 采用 SOT‑323 小封装,体积小、适用于高密度贴片PCB。由于封装本身热阻较大,长时间高电流工作时应注意散热设计:建议在封装下方和引脚周围保留适当铜箔面积以改善散热;若连续工作电流逼近 200 mA,应评估 PCB 温升并保证结温在额定范围内。

四、典型应用场景

  • 高速开关电路:载波切换、逻辑线驱动与门阵列保护等需要快速恢复的场合。
  • 小信号整流与采样:便携设备与传感前端的微电流整流与保护。
  • 电平转换与夹位:用于电压隔离、双向限幅。
  • 保护电路:短时浪涌吸收、输入保护(结合限流器件使用)。
    其低漏电和短恢复时间使其在高频率切换与低功耗系统中具有优势。

五、设计与使用注意事项

  • 测量条件:正向压降与反向电流随测试电流和温度变化明显,设计时应留足裕量。
  • 脉冲能力:若电路中存在较大浪涌或重复脉冲,应校核 Ifsm 与结温升高,必要时加入限流或散热措施。
  • 焊接工艺:SOT‑323 兼容标准回流焊曲线,但要避免超过厂商给定的最高回流温度与时间。
  • ESD 与极性:尽管为小信号器件,仍需在装配与测试过程中注意极性标识与静电防护。
  • PCB 布局:共阴极结构在布局时方便实现共用接地(或共阴端)走线,但要注意回流电流路径与寄生电容对高速性能的影响。

六、与同类器件比较

LBAW56WT1G 与常见的 BAW56 类双二极管在电气特性上高度接近:均提供共阴极结构、约 70 V 反向耐压、200 mA 级别的连续电流以及纳秒级恢复时间。LBAW56WT1G 优势在于由 LRC 出货,适配国内供应链需求,且封装为 SOT‑323,有利于高度集成的便携式产品设计。

七、采购建议与替代型号

  • 采购信息:型号 LBAW56WT1G,品牌 LRC,封装 SOT‑323。批量采购时建议向供应商确认封装标识、最低供货量与包装(卷装/托盘)。
  • 替代型号:如需通用替代,可参考 BAW56 系列或其他厂家的同等级双二极管,但在替换前应核对 Vf、Vr、Trr、Ifsm 及封装针脚兼容性。

总结:LBAW56WT1G 是一款面向高速切换与小信号整流的双二极管产品,具有低正向压降、低漏电与短反向恢复时间等优点,适合便携设备、接口保护与高速逻辑电路。设计时应关注散热、脉冲能力与 PCB 布局,以确保长期可靠工作。若需更详细的参数表与典型波形图,请参阅厂商数据手册或联系供应商获取样片测试资料。

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.
