HER108是MDD品牌推出的轴向引线式高效率整流二极管,采用DO-41标准封装,针对中小功率高频整流场景优化设计,兼具高速性能与高压耐受能力,是开关电源、工业控制等领域的常用器件。
HER108的型号明确其“高效率整流器(High Efficiency Rectifier)”定位,品牌为MDD,封装形式为DO-41轴向插装结构——该封装体积小巧(直径约2.7mm,长度约5.2mm),引线便于手工/机器焊接,兼容多数PCB板插件工艺,成本可控且安装便捷,适合批量生产场景。
HER108的参数围绕“高速、高压、低损耗”核心设计,具体表现为:
HER108的性能匹配多类电路需求,常见应用包括:
HER108的核心竞争力体现在:
HER108结温上限150℃,实际使用需注意PCB散热(如增加铜箔面积),避免结温超额定值;反向耐压1kV为直流值,脉冲电压下需降额至80%使用,保障长期可靠性。MDD作为成熟品牌,该器件一致性与稳定性已通过多数工业级应用验证。
整体来看,HER108是性价比突出的高速高压整流二极管,适用于消费电子、工业控制、汽车电子等多领域中小功率高频整流场景,能有效提升电路效率与可靠性。

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.
