LBAT54WT1G 肖特基二极管产品概述

一、产品基本定位与品牌背书

LBAT54WT1G是乐山无线电(LRC) 推出的低功耗表面贴装肖特基二极管,属于BAT54系列衍生型号,针对低压小电流电路的整流、续流等场景优化设计。LRC作为国内半导体行业老牌厂商,拥有成熟的功率器件制造工艺,产品可靠性符合工业级标准,广泛应用于消费电子、电源管理等领域。

二、核心电气参数及实际意义

该型号的关键参数直接决定了适用场景,具体解析如下:

  1. 正向特性:正向压降(Vf)典型值400mV(远低于普通硅二极管的700mV),直流整流电流200mA。低Vf可显著降低整流/续流过程中的自身功耗,尤其适合3.3V、5V等低压电源系统,减少发热并提升电源效率。
  2. 反向特性:直流反向耐压(Vr)30V(覆盖大部分低压电路反向偏置需求),反向漏电流(Ir)仅2uA(极小漏电流避免反向状态下的能量损耗,适合电池保护、低待机电路)。
  3. 瞬态与温度特性:非重复峰值浪涌电流(Ifsm)600mA(单次脉冲10ms内),工作结温范围-55℃至+125℃。600mA浪涌能力可应对启动瞬间电流冲击;宽温范围确保极端环境(工业高温、户外低温)下稳定工作。

三、封装形式与物理优势

采用SOT-323(SC-70)超小型表面贴装封装,尺寸约1.6mm×0.8mm×0.6mm,具有三大优势:

  • 高密度集成:小尺寸大幅节省PCB空间,适配智能手机、可穿戴设备等对空间严苛的产品;
  • 贴片兼容性:符合标准SMD工艺,支持回流焊、波峰焊自动化生产,降低制造成本;
  • 散热适配:针对200mA额定电流设计,配合PCB散热焊盘可满足长期工作的散热需求。

四、典型应用场景

结合参数特性,该型号主要适用于:

  1. 低压电源整流:5V/1A以下USB适配器、DC-DC降压转换器输出整流;
  2. 开关电路续流:MOSFET/三极管驱动电路的续流二极管,减少开关损耗;
  3. 电池保护电路:锂电池充放电回路反向截止,低漏电流延长待机时间;
  4. 便携电子设备:智能手机、蓝牙耳机、智能手环的电源管理模块;
  5. 工业低压控制:PLC、传感器模块的辅助电源电路(适应宽温环境)。

五、产品优势与替代价值

相较于进口同类产品(如某品牌BAT54),LBAT54WT1G优势明显:

  • 性价比突出:国内厂商定价更具竞争力,适合大规模量产;
  • 参数一致性好:批量生产中Vf、Ir等关键参数波动小,提升电路稳定性;
  • 本土化服务:LRC国内销售与技术支持网络完善,快速响应客户需求。

六、应用注意事项

为确保可靠性,使用时需注意:

  1. 浪涌限制:600mA为非重复峰值电流,不可持续工作,避免瞬态电流超额定值;
  2. 结温控制:长期工作结温≤125℃,近200mA电流时需辅助散热(如PCB散热焊盘);
  3. 焊接规范:回流焊温度≤260℃,焊接时间≤30秒,避免热应力损坏;
  4. 反向电压限制:直流反向电压≤30V,瞬态反向电压≤36V(额定值1.2倍)。

总结

LBAT54WT1G凭借低功耗、小封装、宽温特性,在低压小电流电路中应用广泛,是消费电子、电源管理等领域替代进口产品的优质选择,兼具性价比与可靠性。

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
