SM8S36CA 产品概述

一、产品简介

SM8S36CA 是 FUXINSEMI(富芯森美)推出的一款高可靠性双向 TVS(瞬态电压抑制)二极管,专为汽车及工业环境下的瞬态浪涌保护设计。器件采用结钝化优化和钝化各向异性整流器工艺(passivated anisotropic rectifier),在高温及严苛电气环境下仍能保持低漏电、低正向压降和强大的浪涌承受能力,结温上限 TJ = 175℃,满足汽车级应用要求。

二、关键电气参数

  • 极性:双向(Bidirectional),安装时无极性要求,适用于交流或极性可变的电源线保护。
  • 反向截止电压 VRWM:36 V(典型工作耐压)。
  • 击穿电压 VBR:40 V(标称)。
  • 钳位电压 VCL:58.1 V(在峰值脉冲条件下)。
  • 峰值脉冲电流 Ipp:114 A(器件对瞬态电流的承受能力)。
  • 峰值脉冲功率 Ppp:6.6 kW(短时脉冲能量吸收能力)。
  • 反向漏电流 Ir:10 µA(在额定反向电压下低漏电,有利于车辆低功耗需求)。
  • 工作温度范围:-55 ℃ ~ +175 ℃(适配高低温循环环境)。

三、结构与工艺优势

器件采用结钝化与钝化各向异性整流器技术,提升了表面稳定性与击穿一致性,显著降低漏电及噪声。DO-218AB 封装提供优良的热散能力和机械强度,适合于高能量冲击环境下长期可靠工作。低正向压降特点在双向工作模式下尤其有利,可减少导通时的功耗与热量产生。

四、典型应用

  • 汽车电源总线与子系统防护:发动机ECU、车身控制模块、车载充电器、传感器供电线等。
  • 负载突降与反向电压保护:感性负载开关引起的尖峰电压、负载断开瞬态抑制(load-dump)。
  • 工业控制与通信设备:保护敏感模拟/数字接口免受雷击或开关瞬态。
  • 其他需高能量吸收且要求高可靠性的场合。

五、封装与可靠性

封装:DO-218AB,利于机械焊接与散热管理;适配波峰/回流焊或机械固定安装。器件设计满足汽车级耐久性与热循环要求,工作结温上限 175 ℃,适合引擎舱等高温工况。

六、选型与使用建议

  • 确保 VRWM(36 V)高于系统最大工作电压并留有安全裕量,避免费禁用状态下频繁进入击穿区。
  • 双向器件适用于无固定极性的线路或需同时抑制正负向瞬态的场合;若系统极性固定,可考虑单向器件以获得更低钳位。
  • 布局时尽量将器件靠近受保护点并保证良好接地回路,短而粗的地线能提升吸收能力与降低环路感应。
  • 注意热设计:高能脉冲会产生热量,必要时结合散热片或良好的 PCB 散热铜箔以保障重复浪涌能力。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

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
