DSS320是伯恩半导体(BORN) 推出的一款中功率表面贴装整流二极管,专为小体积、高可靠性、宽温适应的低压整流场景设计。伯恩半导体作为专注功率器件研发的厂商,其产品以工业级/汽车级品质把控为核心,DSS320继承了品牌在芯片设计、封装工艺上的成熟经验,适合消费电子、工业控制、汽车电子等多领域的电源转换需求。
DSS320的关键参数围绕“低压大功率、低损耗、宽温可靠”设计,具体如下:
该参数为器件允许的最大反向耐受电压,200V的额定值可覆盖12V/24V/48V 等主流低压系统(如汽车电源、工业传感器电源),且留有裕量应对电路瞬态尖峰电压(如开关电源过冲),避免反向击穿损坏。
指25℃环境下可持续工作的平均整流电流,满足小功率电源适配器(手机快充、笔记本电源)、LED驱动电源的整流需求。注意:环境温度高于25℃时需降额使用(如100℃时电流能力约2A,参考官方 datasheet)。
额定反向电压下,反向漏电流仅100μA(25℃时),远低于同类产品平均水平。低漏电流意味着反向损耗极低,可提升电源转换效率,尤其适合便携设备(无线耳机充电盒、智能手表充电器)。
这是芯片允许的结温范围,宽温特性适配极端环境:低温端-55℃满足北方户外设备、车载低温启动;高温端+150℃支持工业现场高温作业(烤箱、注塑机辅助电源),无需额外散热即可稳定工作。
DSS320采用SOD-123FL 表面贴装封装,核心优势如下:
DSS320的参数与封装特性适配多领域低压整流需求,典型应用包括:
为确保长期可靠工作,需注意以下要点:
DSS320凭借200V/3A参数、100μA低漏电流、-55℃~+150℃宽温、SOD-123FL小封装 等优势,成为低压整流场景的高性价比选择。其适配多领域需求,可靠性经伯恩成熟工艺验证,是设备小型化、高效化设计的理想器件。
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.
