SS54L是JUXING(钜兴) 推出的独立式肖特基二极管,采用DO-214AC(SMA)表面贴装封装,属于中功率低压肖特基器件。其核心定位是为低压直流电路、开关电源等场景提供高效整流、续流及瞬态保护,凭借低正向压降、宽温耐受及抗浪涌能力,适配高密度贴装设计需求。
SS54L的电性能参数针对性满足低压中功率场景,核心参数及实际意义如下:
肖特基二极管的核心优势——远低于普通硅PN结二极管(0.6~0.7V),导通时功率损耗仅为( P=Vf \times If=450mV \times 5A=2.25W ),比硅二极管(3.5W)降低36%,显著提升电路效率,减少散热需求。
满足12V/24V等低压直流系统的反向阻断需求,避免电路反向击穿,适配电池组、太阳能充电等低压场景。
持续工作时的最大允许电流,覆盖常规中功率负载(如小型电机、LED阵列)的整流需求,无需额外并联器件。
反向状态下漏电流极小,减少待机损耗,提升电路稳定性(尤其适合低功耗设备)。
可耐受突发浪涌(如开机瞬间、负载突变、汽车启动冲击),增强电路抗干扰能力,避免器件损坏。
宽温环境下保持性能稳定,适应工业控制(-4085℃)、汽车舱内(-40125℃)等极端温度场景,无需额外散热降额。
SS54L采用DO-214AC(SMA)表面贴装封装,具备以下优势:
SS54L的参数特性使其广泛适配以下场景:
高频开关电源(如适配器、LED驱动)中,肖特基的低Vf和快速恢复特性(隐含优势)适合续流二极管,减少开关损耗,提升电源转换效率(可达90%以上)。
12V/24V电池组、太阳能充电控制器、电动车辅助电源等,40V耐压足够,5A电流覆盖常规负载,宽温范围适应户外环境。
车载充电器、LED尾灯驱动、CAN总线保护等,-55~150℃结温满足汽车舱内极端温度,110A浪涌耐受应对启动冲击。
手机充电器、智能手表充电底座、蓝牙音箱电源,低损耗提升续航,小封装适配便携设备设计。
防止电池过充/过放时的反向电流,浪涌能力保护电池免受瞬态冲击(如短路恢复瞬间)。
JUXING(钜兴)是国内专注功率器件的专业制造商,SS54L具备以下品质背书:
SS54L肖特基二极管凭借低损耗、宽温、抗浪涌、小封装四大核心优势,成为低压中功率整流场景的高性价比选择,广泛适配消费电子、工业控制、汽车电子等领域的设计需求,是工程师优化电路效率与可靠性的实用器件。
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.
