SS36(SMB封装)肖特基二极管产品概述

SS36是一款表面贴装肖特基势垒二极管,采用SMB(DO-214AA)封装,由台湾迪嘉(TWGMC)出品,主打低压大电流整流与续流应用,以低导通损耗、高可靠性为核心优势。以下从产品特性、参数、应用等维度展开概述:

一、产品基本信息与封装特性

SS36属于独立式单管封装,封装类型为SMB(表面贴装),尺寸紧凑(典型规格约2.3×3.0×1.0mm),无长引脚设计,适配高密度PCB布局,适合小型化电子设备。TWGMC作为台湾本土半导体厂商,其产品符合RoHS等主流环保标准,在工业级可靠性与成本控制上具备竞争力,可满足全球市场批量采购需求。

二、核心电气参数深度解析

SS36的电气参数针对低压大电流场景优化,关键指标清晰支撑应用需求:

  1. 正向导通特性:正向压降Vf=700mV@3A,显著低于普通硅整流二极管(典型值~1V@3A),导通损耗降低约30%,可减少电源电路发热,提升转换效率;
  2. 反向耐压与漏电流:直流反向耐压Vr=60V,满足12V/24V低压系统需求;反向电流Ir=500uA(额定条件下),漏电流小,长时间工作无明显反向功耗积累;
  3. 电流承载能力:连续整流电流Id=3A(直流),稳定支撑中功率负载;非重复峰值浪涌电流Ifsm=80A(8.3ms半波脉冲),可应对电源启动、负载突变等瞬间过流场景,降低器件损坏风险;
  4. 结温范围:工作结温为-55℃~+150℃,宽温特性适配工业控制、汽车电子等高低温环境,无需额外降额即可稳定工作。

三、典型应用场景

SS36的参数特性决定其适用于以下核心场景:

  1. 低压开关电源整流:如5V/12V/24V小功率开关电源的次级整流,低Vf减少发热,提升电源转换效率;
  2. DC-DC转换器续流:在buck/boost电路中作为续流二极管,肖特基固有的快速导通/关断特性提升电路响应速度;
  3. 电源极性保护:用于防止电池或电源反接,低Vf可减少正向压降损耗,反向耐压满足低压系统防护需求;
  4. 小型充电电路:如蓝牙耳机、智能手表的充电底座,SMB封装适配小型化设计,低损耗延长电池续航;
  5. 消费电子与工业控制:机顶盒、路由器、PLC等设备的电源模块,宽温特性与浪涌能力适配工业级环境。

四、可靠性与环境适应性

SS36在可靠性设计上具备以下优势:

  1. 宽温可靠性:-55℃~+150℃结温范围覆盖绝大多数应用场景,无需额外散热设计即可满足工业级要求;
  2. 浪涌耐受能力:80A非重复浪涌电流可应对电源启动时的瞬间冲击,减少批量生产中的失效概率;
  3. 封装可靠性:SMB封装采用塑料/陶瓷封装,抗振动、抗冲击性能优于直插封装,适合车载、手持设备等振动环境;
  4. 低漏电流稳定性:500uA反向漏电流在结温范围内变化平缓,长期工作无明显性能衰减。

五、选型价值与注意事项

SS36作为TWGMC的成熟产品,具备以下选型价值:

  1. 成本优势:替代进口同类产品,性价比提升约20%-30%;
  2. 封装一致性:批量生产中引脚尺寸、电气参数一致性好,适配自动化贴装;
  3. 应用灵活性:单管封装可灵活组合,满足不同功率需求;

注意事项:肖特基二极管反向耐压相对较低(60V),避免用于高压场景;焊接时需控制温度(SMB封装焊接温度≤260℃,时间≤10s),防止结温过高损坏器件。

总结:SS36(SMB封装)肖特基二极管以低损耗、高可靠性、小型化封装为核心,适配低压大电流整流与续流场景,是消费电子、工业控制、汽车电子等领域的高性价比选型。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
