SS12A是扬杰科技(YANGJIE)推出的一款小功率贴片肖特基整流二极管,采用SMA(DO-214AC)封装,以低正向压降、高可靠性为核心特点,广泛适配低压直流电源、便携式电子等场景的整流需求。
扬杰科技作为国内功率半导体龙头企业,专注于分立器件的研发生产,SS12A是其针对1A级小功率整流市场推出的标准化产品,主打“低成本+高性能”平衡,满足消费电子、工业控制等领域的通用需求。该产品为独立式结构,无内部并联单元,一致性与稳定性表现优异,适合批量集成应用。
SS12A的关键参数围绕“低压、低损耗、高可靠性”设计,具体如下:
正向压降(Vf):500mV@1A
肖特基二极管的核心优势,远低于传统硅整流二极管(通常1V以上),可显著降低导通损耗,减少电路发热,尤其适合5V、12V等低压电源系统。
直流反向耐压(Vr):20V
额定反向耐受电压,明确产品电压应用上限;实际使用建议保留20%裕量(≤16V),避免过压击穿。
额定整流电流(IF):1A
连续正向工作电流的额定值,满足多数小功率场景(如USB充电、小型家电电源)的需求;峰值电流(IFSM)通常可达30A(8.3ms单脉冲),可应对瞬间浪涌。
反向漏电流(Ir):500μA@20V
反向电压下漏电流极小,降低反向损耗,提升电路效率,同时减少反向发热对器件的影响。
工作结温范围:-55℃~+125℃
宽温范围覆盖工业级与部分汽车电子场景,可适应低温(如北方户外设备)与高温(如密闭电源盒)环境。
SS12A采用SMA(DO-214AC)贴片封装,具备以下特点:
SS12A的参数特性使其适配以下主流场景:
为保障产品性能与寿命,使用时需注意以下要点:
综上,扬杰SS12A是一款性价比突出的小功率肖特基整流二极管,凭借低Vf、宽温、小封装等优势,可满足多数通用整流场景的需求,是消费电子、工业控制等领域的优选器件之一。
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.
