SMF36CA(MDD)产品概述

一、产品简介

SMF36CA 是 MDD 提供的一款双向瞬态电压抑制器(TVS 二极管),封装为 SOD-123FL。该器件专为抑制交流或双向脉冲瞬变而设计,能在正负方向上对过电压事件进行钳位保护,适用于空间受限且需双向保护的电源与信号线路中。

二、主要电气参数

  • 极性:双向
  • 反向截止电压 Vrwm:36 V
  • 击穿电压(Vbr):44.2 V
  • 钳位电压(典型):58.1 V(在额定脉冲条件下测得)
  • 峰值脉冲电流 Ipp:3.4 A
  • 峰值脉冲功率 Ppp:200 W
  • 反向漏电流 Ir:1 µA(在 Vrwm 条件下典型值)
  • 工作温度范围:-55 ℃ ~ +150 ℃
  • 封装:SOD-123FL
  • 类型:TVS(二极管)

三、性能特点与优势

  • 双向结构:可同时抑制正、负极性的瞬态脉冲,适用于交流或有反向浪涌的应用场景。
  • 低漏电流:Ir 典型仅 1 µA,有利于在待机或低功耗电路中减少能耗与误触发。
  • 良好钳位能力:钳位电压 58.1 V(典型)在发生浪涌时能迅速将过电压钳制到安全范围,配合 200 W 的瞬态功率处理能力可应对常见的雷击或开关干扰脉冲。
  • 宽温度适应:-55 ℃ 到 +150 ℃ 的工作温度区间,满足工业级应用环境需求。
  • 小型低剖面封装:SOD-123FL 便于在空间受限的 PCB 上布置,且电感、电容寄生参数较低,响应速度快。

四、典型应用场景

  • 开关电源输入及输出保护,特别是 24 V / 36 V 级别的工业电源线路(选型需考虑 Vrwm 与实际工作电压裕量)。
  • 通信端口、数据线、接口电路的浪涌与静电防护(双向信号线)。
  • 家用和工业设备的电源接口、继电器驱动和逆变器输入端的瞬态抑制。
  • 任何需要在有限空间内实现高效双向浪涌保护的电子产品。

五、安装与选型建议

  • Vrwm=36 V 表示器件在反向工况下的允许稳态电压,选型时应保证电路正常工作电压低于 Vrwm,并预留足够裕量以避免频繁触发。
  • 钳位电压与浪涌能量有关,若系统能承受的最大瞬态电压低于 58.1 V,应考虑并联更大功率或更低钳位电压的 TVS 器件。
  • 尽量将 TVS 器件布局靠近被保护端口并采用短、粗的连接走线以减小寄生电感,提高响应速度与散热能力。
  • 在高能量浪涌环境(如直击雷或高能开关电源)中,建议与输入滤波、电阻限流或气体放电管等器件配合使用以分担能量。

六、可靠性与采购关键信息

MDD 品牌的 SMF36CA 在工业温度范围内具有稳定的工作特性。采购时建议确认供应商提供的完整数据手册、浪涌测试条件(例如脉冲波形 8/20 µs 或其他)以及封装引脚图,以便在具体设计中准确评估钳位电压与峰值电流对应关系。若用于汽车或更苛刻的场景,请核实器件是否满足相关认证(如 AEC-Q 等)或选择相应等级的器件。

总结:SMF36CA(SOD-123FL)是一款适合中等能量双向瞬态抑制的 TVS 器件,体积小、漏电低、耐温范围广,适用于多种需要双向保护且空间受限的应用。

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
