KBAT54S-7-F是KUU品牌推出的一款1对串联式肖特基二极管,采用SOT-23小型贴片封装,专为低压小电流场景设计,兼顾了小体积、低功耗与快速响应特性,广泛适用于便携式设备、射频电路等领域。
该器件属于通用型肖特基二极管范畴,核心为2只肖特基二极管串联的结构设计,封装采用行业标准SOT-23(典型尺寸1.6mm×1.0mm×0.8mm),具有以下封装优势:
KBAT54S-7-F的电性能参数针对低压小电流场景做了针对性优化,核心参数如下:
在100mA正向电流下,总正向压降为1V——这是2只肖特基二极管串联后的典型值(单管肖特基正向压降通常为0.3~0.5V)。该压降稳定,温度系数小(约-2mV/℃),可用于需要特定正向压降的钳位、偏置电路。
额定直流整流电流200mA:可稳定承载200mA的连续正向电流,适合小功率整流(如5V/100mA电源输出)、续流(如小电机驱动回路)等场景。
结合参数特性,KBAT54S-7-F的核心应用场景包括:
相比同类产品,KBAT54S-7-F具有以下设计优势:
反向漏电流仅2μA,在待机状态下几乎不消耗额外功率,尤其适合电池供电的便携式设备,可延长单次充电续航时间10%~15%(实际取决于电路设计)。
肖特基二极管无反向恢复时间,可避免高速电路中的开关损耗,提升信号完整性,适用于100MHz以上的高频应用。
为确保器件性能与寿命,使用时需注意以下几点:
肖特基二极管对静电敏感(人体静电可达到几千伏),生产、组装过程中需采用ESD防护措施:
KBAT54S-7-F作为一款1对串联式肖特基二极管,以小体积、低功耗、快速响应为核心优势,覆盖了便携式设备、低压电路保护、高速信号处理等多场景需求。其参数优化与成本效益使其成为消费电子、工业控制等领域的高性价比选型。
Request for quote
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
