BAT54CT 产品概述
一、概述
BAT54CT 为双路肖特基（二极管对）器件，采用共阴极（两只二极管共阴极端）配置，适用于低电压快速整流与保护场合。该器件由 YANGJIE（扬杰）提供，封装为 SOT-523，体积极小，适合空间受限的便携设备与高密度电路板使用。典型特性为低正向压降、快速响应与较低反向漏电，适配 100mA 级别的工作电流场景。
二、主要电气参数
- 二极管类型：肖特基，1对共阴极
- 正向压降（Vf）：1.0V @ If = 100mA（单只）
- 直流反向耐压（Vr）：30V（最大）
- 连续整流电流（Io）：200mA（总或单路按厂方定义）
- 反向漏电流（Ir）：2µA @ Vr = 25V（典型/最大值）
- 非重复峰值浪涌电流（Ifsm）：600mA（单脉冲）
这些参数表明 BAT54CT 在 100mA 级别负载下仍能保持较低的压降与有限的功耗，同时具备一定的浪涌承受能力。
三、封装与引脚说明
封装：SOT-523（极小型表贴）。
SOT-523 的热阻较大，散热能力受限，因此在持续大电流或高占空比开关条件下需注意布局与散热。引脚排列按照共阴极配置，便于并联或作为 OR-ing、极性保护结构使用。
四、典型应用场景
- 电源反向保护、输入极性保护（低压移动设备、消费电子）
- 电源 OR-ing（多电源切换）与备用电源选择
- 快速开关整流与钳位（高频开关、信号线钳位）
- 电平位移、低电压整流与检测电路
- 小功率电源模块、便携设备与射频前端保护
五、选型与使用建议
- 热管理：SOT-523 为小型封装，长期接近 200mA 连续工作时需评估 PCB 散热路径与铜箔面积，必要时选用更大封装或并联器件。
- 浪涌应对：Ifsm = 600mA 表示能承受短时浪涌，但不适合作为频繁大电流冲击的主件。
- 漏电与导通压降：反向漏电 2µA（25V）适合大多数低功耗场合，但在超低泄漏要求的电路中需谨慎。正向压降 1V 在 100mA 时属常见肖特基表现，若需更低压降可选更高规格型号。
- 布局要点：将器件尽量靠近负载或电源输入布置，缩短走线，增大焊盘散热面积，避免热聚集影响可靠性。
六、总结
BAT54CT（YANGJIE，SOT-523）是一款面向低压、低功耗与空间受限应用的共阴极肖特基二极管对，具备 30V 反向耐压、1V@100mA 的正向压降、200mA 连续整流能力及 600mA 的短时浪涌承受力。合理的热设计与按需选型能使其在便携设备、电源保护与快速整流等场合发挥良好性能。

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.
