LBAT40HT1G — 肖特基二极管产品概述
一、产品简介
LBAT40HT1G 是乐山无线电（LRC）出品的一款低正向压降肖特基整流二极管，采用 SOD-323 小外形封装，专为低功耗和快速开关应用设计。凭借较低的正向压降和极小的反向漏电，适合移动电源、便携设备以及各种低电流电源路径保护场合。
二、主要参数
- 正向压降 (Vf)：典型 600 mV @ If = 200 mA
- 直流反向耐压 (Vr)：40 V
- 连续整流电流 (If)：350 mA
- 反向电流 (Ir)：典型 1 μA（常温、标称 Vr 条件下）
- 非重复峰值浪涌电流 (Ifsm)：1.5 A（单次脉冲）
- 封装：SOD-323
这些参数表明器件适合中低电流、高频率切换场合，同时在 40 V 以下工况能提供可靠的反向阻断能力。
三、产品特点
- 低正向压降：在 200 mA 工作点上约 0.6 V，减少功率损耗和发热，提升系统效率。
- 小封装：SOD-323 占板面积小，有利于高密度 PCB 布局和便携设备小型化。
- 漏电小：反向电流约 1 μA，适合待机与低功耗场景。
- 快速响应：肖特基结构无恢复时间，适合高频整流与保护电路。
四、典型应用
- 电源反接/极性保护二极管（输入端或电源路径）
- 移动设备和便携式电源的低压降整流与续航优化
- 开关电源输出整流（低至中等电流）
- 信号钳位、保护回路及高频整流场合
五、封装与组装注意事项
SOD-323 为热阻较高的小体积封装，长时间大电流会引起结温上升，设计 PCB 时应注意散热路径与铜箔面积。推荐合理布线，加大焊盘和散热铜箔；回流焊温度曲线按元件供应商推荐执行，避免过猛的热循环导致可靠性下降。建议在 PCB 布局阶段预留测试点以便量测 Vf 与漏电。
六、可靠性与选型建议
在选型时，注意工作环境温度与实际电流波形（连续与脉冲）。若电路存在较高瞬态浪涌或长期接近额定 If，建议选用更大尺寸或更高 Ifsm 的器件以提高可靠性。对极低漏电或更高耐压需求，可考虑其他系列或封装的肖特基/肖特基改良型器件。
七、订购信息与可替代型号
型号：LBAT40HT1G，品牌：LRC（乐山无线电），封装：SOD-323。常见替代选择可考虑满足相近 Vf、Vr 与 If 规格的同类肖特基器件，替换前请核对温度特性和浪涌能力以保证系统兼容。若需样片、数据手册或贴片封装图，请联系供应商或授权分销商获取完整资料。

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.
