LBAV170LT1G开关二极管产品概述

LBAV170LT1G是乐山无线电(LRC)推出的一款1对共阴极快速开关二极管,采用小型化SOT-23表面贴装封装,以低功耗、宽温适应性和快速开关特性为核心优势,广泛适用于小功率电子设备的信号切换、电源整流及保护电路。

一、产品核心定位

该器件针对小功率、高密度PCB设计场景优化,核心定位清晰:

  • 共阴极结构(双二极管共享阴极、阳极独立),可实现双路独立开关/整流功能;
  • 3μs反向恢复时间兼顾开关速度与成本,适配大多数中高速信号处理需求;
  • 150mW低额定功耗,降低系统待机损耗,适合便携式设备等对功耗敏感的场景。

二、关键参数详解

LBAV170LT1G的核心参数精准匹配小功率应用,具体意义如下:

参数类别 数值 实际应用价值 二极管配置 1对共阴极 双二极管共享阴极,阳极独立,可实现信号选通、双路续流等功能 正向压降(Vf) 1V(典型) 导通电压低于普通整流管,减少导通损耗,适合低电压电源系统 直流反向耐压(Vr) 85V 反向截止时可承受85V直流电压,满足12V~48V电源的过压防护需求 整流电流(If) 215mA 直流导通额定电流,适配5V/100mA、12V/50mA等小功率电源的整流/续流 耗散功率(Pd) 150mW 最大允许功耗,需通过PCB铜箔散热(如增加引脚焊盘面积)控制结温不超150℃ 反向电流(Ir) 5nA(典型) 反向漏电流极小,保证反向绝缘性,降低电池供电设备的待机损耗 反向恢复时间(Trr) 3μs 开关从导通到截止的恢复时间,属于快速恢复范畴,避免反向浪涌电流冲击 工作结温(Tj) -65℃~+150℃ 宽温范围,适应工业级环境(车载、户外设备)或极端温度场景

三、封装与引脚配置

采用SOT-23表面贴装封装,尺寸约1.6mm×2.9mm×1.1mm,特点突出:

  • 小型化设计:适合高密度PCB布局,减少设备体积(如智能手环、蓝牙耳机);
  • 引脚配置(共阴极):
    引脚1 → 阳极1(D1阳极);
    引脚2 → 共阴极(D1、D2阴极共接);
    引脚3 → 阳极2(D2阳极);
    (注:SOT-23封装仅3个有效引脚,无空脚,简化焊接与布局)

四、典型应用场景

结合参数特性,该器件主要应用于以下场景:

1. 小型电源电路

  • 5V/12V小功率电源整流(如USB辅助电源、智能穿戴充电电路);
  • 开关电源续流(配合MOS管实现电感续流,减少反向浪涌)。

2. 高速信号切换

  • 中速信号选通(如音频切换、数据总线切换);
  • 脉冲整形(利用3μs恢复时间滤除信号毛刺,提升信号质量)。

3. 保护电路

  • 过压保护:信号电压超85V时反向击穿,钳位电压保护后端IC;
  • ESD防护:小封装适合IC引脚防护,漏电流低不影响信号传输。

4. 便携式设备

  • 手机、蓝牙耳机的电源管理模块(功耗低、体积小);
  • 智能穿戴的传感器信号处理(宽温适应人体佩戴环境)。

五、可靠性与环境适应性

该器件通过LRC可靠性测试,满足:

  • 宽温稳定性:-65℃~+150℃工作结温,可在低温户外或高温车载环境稳定工作;
  • 耐浪涌能力:反向耐压+快速恢复时间,承受短时间浪涌电压(如电源启动瞬间);
  • 环保合规:符合RoHS标准,无铅封装,适配绿色电子产品设计。

六、品牌与制造背景

乐山无线电(LRC)是国内领先的分立半导体制造商,拥有50+年器件研发生产经验,产品覆盖二极管、三极管等品类。LBAV170LT1G采用LRC成熟工艺,品质稳定,供货周期短,广泛应用于消费电子、工业控制领域。

总结:LBAV170LT1G以共阴极结构、快速开关、小封装和宽温特性为核心,是小功率开关/整流场景的高性价比选择,尤其适合对体积、功耗有要求的便携式设备及工业应用。

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
