S1M是晶导微电子推出的通用型独立式整流二极管,采用SMA(DO-214AC)贴片封装,专为1A级小功率直流整流场景设计,核心参数匹配常规电子设备的电源转换需求。其关键参数可快速概括为:
在1A额定整流电流下,正向压降稳定在1.1V,既避免了过高压降导致的导通损耗(适合低功耗场景),又保证了足够的导通可靠性——连续工作时的功率损耗约1.1W,可通过常规PCB铜箔实现有效散热。
直流反向耐压达1kV,可覆盖常规高压辅助电源、部分工业控制电路的反向阻断需求;反向漏电流仅5μA@1000V,远低于同类器件平均水平(通常10μA以上),能减少反向功耗,提升电路在待机状态下的稳定性。
非重复峰值浪涌电流(Ifsm)为30A,可有效应对电源启动瞬间的脉冲电流、负载突变(如LED灯突然全亮)等异常工况,降低器件因过流损坏的风险。
工作结温范围覆盖-55℃至+150℃,符合工业级器件标准,可在高低温环境(如户外设备、车载辅助电路)中稳定工作,无需额外散热措施即可满足常规场景需求。
S1M采用SMA(DO-214AC)贴片封装,具有以下核心优势:
S1M因参数均衡、体积小巧,广泛应用于以下场景:
手机、平板、蓝牙耳机等小型设备的电源适配器整流(将交流220V转换为低压直流的前级整流);
小功率LED台灯、灯带的辅助整流电路(1A电流满足5-10颗LED串联的功率需求);
洗衣机、空调、微波炉等家电的辅助电源(如待机电源、传感器供电电路);
小型PLC、传感器模块的低压直流电源整流(宽温特性适应工业环境的温度波动);
汽车中控、仪表盘的小功率辅助电源(需应对车载-40℃~85℃的温度范围)。
作为晶导微电子的主流整流器件,S1M具有以下选型优势:
S1M凭借均衡的性能、紧凑的封装与稳定的可靠性,成为小功率整流场景的高性价比选型,可广泛替代进口器件,降低终端产品成本。

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.
