M1是晶导微电子推出的一款独立式通用整流二极管,采用SMA(DO-214AC)贴片封装,以高可靠性、宽温适配、紧凑体积为核心优势,覆盖小功率低压整流场景的核心需求,是消费电子、小型家电、工业辅助电路等领域的优选器件。
M1定位于通用型小功率整流二极管,区别于快恢复、肖特基等特殊二极管,专注于基础整流功能的稳定实现。其基础特征清晰:
M1的电气参数针对低压小功率场景优化,核心参数满足多数实用需求:
正向压降(Vf)为1.1V@1A,在1A额定整流电流下压降稳定,既保证整流效率(压降越低,功耗越小),又适配常见5V/12V低压电源系统的压降预算;额定整流电流(IF)为1A,可满足小功率负载(如12V/0.5A适配器、5V/1A充电模块)的持续工作需求。
直流反向耐压(Vr)达50V,覆盖多数低压电路的反向偏置需求(如市电整流后滤波前的反向电压通常不超过30V);反向电流(Ir)仅5uA@50V,漏电流极小,反向偏置时功耗可忽略,适合对静态功耗敏感的电池供电设备。
工作结温范围为**-55℃+150℃**,远超常规民用器件(通常0℃+125℃),可适配户外设备(如太阳能小夜灯)、工业控制辅助电路(如低温环境下的传感器供电)等高低温场景,无需额外温度补偿。
M1采用SMA(DO-214AC)贴片封装,该封装具备以下优势:
晶导微电子作为国内功率半导体领域的主流厂商,M1产品通过多重品质管控:
M1的参数与封装特性,使其适用于以下核心场景:
M1通用二极管以1A额定电流、50V反向耐压、宽温适配为核心,结合紧凑SMA封装与可靠品质,是低压小功率整流场景的高性价比选择。其灵活的电路应用特性与稳定的参数表现,可满足电子设计工程师对基础整流器件的多数需求。
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.
