LBAT54HT1G 产品概述

一、产品简介

LBAT54HT1G 是东沃(DOWO)推出的一款小型肖特基/整流用途二极管,采用 SOD-323 封装,面向空间受限的消费电子、通信接口和电源前端保护等场合。器件尺寸小、响应快,适合对反向漏流和正向压降有一定限制但不需要高功率处理的低/中电流应用。

二、主要电气参数

  • 正向压降 Vf:1 V @ 100 mA(典型工作点)
  • 额定整流电流:300 mA(连续)
  • 非重复峰值浪涌电流 Ifsm:600 mA(单次浪涌耐受)
  • 直流反向耐压 Vr:30 V(最大反向电压)
  • 反向电流 Ir:2 μA @ 25 V(典型/测试条件)
  • 封装:SOD-323(小型表面贴装)

以上参数表明 LBAT54HT1G 在 30 V 及以下电压、亚安培电流水平具有良好整流与保护能力;较低的反向漏流适合高阻输入或低功耗电路。

三、典型应用场景

  • 电源输入的极性保护与反向保护
  • 小电流整流(开关电源次级、低功耗充电回路)
  • 信号线浪涌或瞬态抑制(与限流/滤波元件配合)
  • TTL/CMOS 接口保护、二极管钳位与电平移位

四、设计与使用要点

  • 封装小,布板时应将器件靠近被保护端口放置,以缩短回路并提升瞬态抑制效率。
  • 由于连续额定电流为 300 mA,长期工作在接近极限电流时需注意热量积累和降额;若有较大平均功率,建议并行或选用更大封装器件。
  • Ifsm 为 600 mA,仅适用于短时浪涌或瞬态情况,不适合频繁或长期的大电流冲击。
  • 反向漏流 2 μA@25 V 表明在多数低功耗场合可接受,但对极低漏流要求的设计应评估是否满足系统待机损耗目标。

五、封装与可靠性

SOD-323 为常见小型贴片封装,适合自动贴装与高密度 PCB 设计。东沃出品一般满足商业级可靠性要求,推荐按生产数据表进行回流焊工艺控制,避免超出建议焊接温度与时间,以保证长期可靠性。

六、选型建议

如目标应用为 300 mA 级别或以下、工作电压 ≤30 V 且要求小封装、快速响应与较小反向漏流,LBAT54HT1G 为性价比较高的选择。若需更低正向压降或更大平均/峰值电流,请参考更大封装或专用肖特基器件,并关注器件热阻与系统热管理设计。

如需完整电气特性曲线、封装尺寸和回流焊工艺说明,请参考东沃官方数据手册或向供应商索取样片/规格书以便工程验证。

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
