LBAT54TW1T1G 产品概述
一、产品简介
LBAT54TW1T1G（品牌：LRC/乐山无线电）为三路独立肖特基二极管，采用SC-88小型贴片封装（SOT-323 相当），适用于体积受限的便携与消费电子产品中作为快速整流、保护与电源切换元件。器件针对低压、低电流应用做了优化，兼顾低压降与低漏电流的要求。
二、主要电气参数
- 三个独立通道，便于并行或分路使用。
- 典型正向压降（Vf）：约 0.40 V @ 10 mA。
- 直流反向耐压（Vr）：30 V。
- 额定整流电流：200 mA（连续）。
- 反向电流（Ir）：2 μA（在指定 Vr 条件下）。
- 非重复峰值冲击电流（Ifsm）：600 mA。
三、产品特点与优势
- 低正向压降：在中、小电流工作点能显著降低功耗与发热，适合电源二选一（ORing）与整流应用。
- 低反向漏电：2 μA 级别漏电有利于待机与低功耗系统。
- 良好的浪涌能力：600 mA 峰值冲击电流支持短时突发电流。
- 小型封装：SC-88 便于高密度布板，适合便携设备与空间受限场合。
- 三通道设计：单芯片实现多路保护或整流，节省板面积与装配成本。
四、典型应用场景
- 电源路径 ORing 与反向保护（低压差切换）。
- 小信号快速整流、检波电路。
- USB、移动设备与便携式电源管理模块。
- 功率保护、反向防护与二次保护电路。
- 低功耗/待机电路中作为低漏电隔离元件。
五、封装与热管理建议
SC-88（SOT-323）为小体积塑封，热阻相对较高。连续工作时建议：
- 保证 PCB 铜箔面积以利散热，必要时在 GND 或电源平面扩展散热垫。
- 在接近额定整流电流（200 mA）工作时进行温升评估并做适当降额。
- 高峰值冲击（Ifsm）为短时能力，不适宜长期以峰值电流工作。
六、使用、装配与可靠性建议
- 建议按典型回流焊工艺进行贴装，遵循厂商推荐的温度曲线以避免封装应力。
- 在高湿/高温环境下应注意防潮处理，焊接前如有需要进行烘干。
- 制作 PCB 封装元件放置与焊盘时参考 SC-88 推荐尺寸，保证良好焊点与热传导。
- 处理时注意静电防护（ESD），以免损伤肖特基结。
- 常见供货形式为卷带（Tape & Reel），型号后缀 G 常表示卷带包装，便于自动贴装。
总结：LBAT54TW1T1G 以其低正向压降、低漏电与三通道小封装的组合，适合便携电源管理与小信号整流保护应用。选型时请结合具体工作电流、功耗与热设计进行系统级评估。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
