该二极管为东芝(TOSHIBA) 推出的小信号肖特基二极管,型号全称1SS396(TE85L,F)。作为针对低压小电流场景优化的器件,其采用SOT-346超小型表面贴装封装,尺寸紧凑,适配高密度PCB设计,广泛应用于便携式电子、低功耗逻辑电路等领域。
正向压降(Vf):典型值600mV@100mA
肖特基二极管的核心优势之一——相比普通硅二极管(典型Vf≥700mV),更低的导通压降可直接减少功率损耗,尤其适合3.3V/1.8V等低电压供电的电路,提升电源效率(如便携式设备的电池续航)。
反向耐压(Vr):额定直流反向耐压40V
满足大多数低压电子系统的反向截止需求(如避免电源反接损坏电路),无需额外串联高压器件,简化设计流程。
平均整流电流(If(AV)):100mA
可稳定承载小功率直流信号的整流任务,适配低功耗设备(如智能手环、蓝牙耳机)的电流需求,无需降额使用即可满足长期工作。
反向漏电流(Ir):典型值5uA@40V
漏电流极小——反向截止时仅微量电流泄露,保证电路反向特性稳定,适合对漏电流敏感的精密电路(如传感器信号调理、逻辑电平转换)。
浪涌耐受能力:非重复峰值浪涌电流(Ifsm)1A
可短暂承受突发大电流冲击(如电源上电瞬间的浪涌、静电放电),提升电路可靠性,减少器件损坏风险。
该器件采用SOT-346超小型表面贴装封装,尺寸约为1.6mm×0.8mm×0.8mm,相比传统插件封装或较大尺寸贴片封装(如SOT-23),可节省约50%的PCB空间,尤其适合手机、智能手表等轻薄化便携式设备的高密度布局。
同时,SOT-346封装符合RoHS环保标准,无铅无卤,适配现代电子产业的环保要求,可直接用于出口产品设计。
该器件凭借“低功耗、小体积、高可靠性”的特点,成为低压小电流场景下肖特基二极管的优选方案,适配当前电子设备轻薄化、低功耗的设计趋势。

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.
