BAT54-AU_R1_000A1是台湾强茂(PANJIT)推出的1对共阳极肖特基二极管,属于小功率整流/钳位专用器件。该产品以低正向压降、低反向漏电流为核心优势,搭配紧凑SOT-23封装,主要面向便携式电子、低电压电源管理、高速信号保护等场景,兼顾性能与空间效率,是替代传统硅二极管的高性价比选择。
产品正向压降(Vf)典型值为600mV@100mA,显著低于普通硅整流二极管(通常0.7V~0.8V)。这一特性在低电压(如3.3V、5V)系统中尤为关键:
采用行业标准3脚SOT-23封装,尺寸仅约2.9mm×2.5mm×1.1mm,体积小巧,适合高密度PCB布局(如智能手环、蓝牙耳机的主板)。引脚布局符合通用规范(典型:引脚2为共阳极,引脚1/3为阴极),便于焊接与电路设计。
适用于5V以下电源的二次整流(如USB Type-C充电电路、3.3V传感器供电),低Vf特性提升电源效率,减少发热。
可用于音频信号、USB数据信号的过压钳位:反向漏电流小不影响信号完整性,30V耐压可有效抑制瞬态过压(如静电放电)。
如蓝牙耳机、智能手表、TWS耳机的充电电路:小封装节省空间,200mA电流满足充电需求,宽温范围适配日常使用环境。
工业级宽温范围(-55℃~+125℃)适配工业传感器、PLC小信号整流,低漏电流保障信号精度。
与同类型产品相比,BAT54-AU_R1_000A1具备以下优势:

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
