SMF36CA(GOODWORK 固得沃克)产品概述

一、产品简介

SMF36CA 是 GOODWORK(固得沃克)推出的一款双向瞬态电压抑制器(TVS),用于对电源线和信号线上瞬态过压的保护。该器件在反向截止电压 Vrwm 为 36V 的条件下工作,具有高能量吸收能力和宽工作温度范围,适用于工业、通信和汽车电子等需要稳健浪涌保护的场合。

二、主要电气参数

  • 钳位电压(Vc):58.1 V(在规定峰值脉冲电流下的典型钳位水平)
  • 击穿电压(Vbr):40 V
  • 反向截止电压(Vrwm):36 V
  • 峰值脉冲功率(Ppp):200 W(瞬态条件下)
  • 峰值脉冲电流(Ipp):3.4 A(对应于标称脉冲试验条件)
  • 反向漏电流(Ir):最高 1 μA(在 Vrwm 条件下)
  • 极性:双向(适合交流或差分线路的双向浪涌保护)
  • 工作结温度:-55 ℃ ~ +150 ℃(Tj)
  • 封装:SOD-123FL(低轮廓贴片封装)

注:在给定 Ipp=3.4 A、Vc=58.1 V 时,瞬态功率约为 58.1×3.4 ≈ 197.5 W,接近标称 200 W 能量能力,体现了器件在规定冲击条件下的稳定钳位性能。

三、特性与优势

  • 双向结构:可直接用于交流、双向差分或正负电源线路,无需分立反向器件。
  • 高脉冲吸收能力:200 W 峰值脉冲功率,能有效吸收短时雷击或开关干扰能量。
  • 低漏电流:典型漏电 ≤1 μA,适合对静态功耗敏感的系统。
  • 宽温度范围:-55 ℃ 至 +150 ℃ 的结温范围,适合苛刻环境与工业级应用。
  • 体积小、易贴装:SOD-123FL 表面贴装封装,适合自动化回流焊工艺,便于高速贴片生产。

四、典型应用场景

  • 36V 级直流电源总线保护,如工业控制电源、通信设备电源。
  • PoE(以太网供电)供电线路的浪涌与ESD保护。
  • 车载电子系统中的瞬态抑制(需核对汽车级认证及额外要求)。
  • PLC、驱动模块、传感器接口等工业设备的输入保护。
  • 线路基板近端保护:电源插座、外部接口处的首级浪涌吸收器。

五、设计与使用建议

  • 放置位置:应尽量靠近被保护端口或电源入口,缩短受保护线路的串联路径以降低感性耦合。
  • PCB 布局:保护器两端走线应最短且加粗,必要时在器件附近设置散热铜箔以改善热耗散。
  • 焊接工艺:SOD-123FL 支持常规回流焊接工艺;为避免热应力影响,建议按制造商回流曲线与焊接规范操作。
  • 并联或备份:在高能量或重复冲击场景,可根据系统冗余要求并联多个器件或在前端增加熔断/限流元件以保护 TVS 本体。

六、器件选型与注意事项

  • 确认系统最大静态工作电压不超过 Vrwm(36V),以避免常态导通或异常发热。
  • 在特定应用(如汽车)使用前,请核对是否需要满足额外认证或更高脉冲能量等级。
  • 参考 GOODWORK 提供的完整规格书获取更详尽的脉冲测试条件(脉冲波形、测试标准)与热性能数据,以完成可靠性评估与热设计。

SMF36CA 以其稳定的钳位性能、较高的瞬态能量承受能力及紧凑封装,适合对 36V 级线路进行高可靠性的浪涌与瞬态过压防护。若需更详细的电气特性曲线、封装尺寸或样片支持,请联系 GOODWORK(固得沃克)或查询官方规格说明书。

Sourcing availability signal

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
