SMF24A_R1_00001 产品概述

一、产品简介

SMF24A_R1_00001 是强茂(PANJIT)推出的一款单向瞬态电压抑制二极管(TVS),用于对静电放电(ESD)和脉冲浪涌进行快速钳位保护。器件采用 SOD-123FL 小型表面贴装封装,针对 24V 工况设计,适合工业控制、通讯接口、电源线和其它需要抑制瞬态过电压的电子系统。其工作温度范围宽(-55℃ 至 +150℃),能在苛刻环境下长期工作。

二、主要参数(概要)

  • 极性:单向(Unidirectional)
  • 反向截止电压 Vrwm:24V
  • 击穿电压 VBR:29.5V
  • 钳位电压(典型):38.9V(在指定脉冲条件下)
  • 峰值脉冲电流 Ipp:5.1A @ 10/1000µs
  • 峰值脉冲功率 Ppp:200W @ 10/1000µs
  • 反向漏电流 Ir:1µA(典型/最大)
  • 工作温度:-55℃ ~ +150℃
  • 防护等级:符合 IEC 61000-4-2(ESD)标准
  • 封装:SOD-123FL
  • 类型:TVS(二极管型瞬态抑制器)

三、功能与特性

  • 精准钳位:在指定冲击(10/1000µs)条件下,器件将过压钳位在约 38.9V,有效保护后端电路免受高电压损害。
  • 低漏电流:反向漏电流仅约 1µA,适合对漏电敏感的电源和信号线应用,降低功耗和误动作风险。
  • 高能量吸收能力:单一脉冲能够承受 5.1A(10/1000µs)瞬态电流,对工业浪涌和雷击感应等场景具有良好防护能力。
  • 宽温区可靠性:-55℃ 至 +150℃ 的工作温度范围满足工业级和户外设备的环境要求。
  • 小型封装:SOD-123FL 提供低占板面积、适合自动化贴装的方案,便于在空间受限的设计中集成。

四、典型应用场景

  • 24V 电源线、分配线及连接器保护(工业自动化、楼宇控制)
  • 通讯接口防护(RS-232/RS-485、CAN 总线等 24V 及附近电压等级)
  • 继电器驱动、马达控制电路的浪涌抑制
  • 端口、外设插口(USB/以太网接口外围保护时若电压等级匹配)
  • 一般电子产品的端口和线缆入侵点的防护,尤其是易受到静电放电和雷电感应的环境

五、选型与使用建议

  • 极性匹配:器件为单向,适用于以地为参考的正向过压防护;若电路要求双向保护,应选用双向 TVS 或用两只单向器件背靠背配置。
  • Vrwm 与系统电压匹配:Vrwm 为 24V,应用于系统静态工作电压等于或低于 24V 的场景,确保正常工作不受击穿影响。
  • 钳位电压考虑:钳位电压 38.9V 表示在承受冲击时被保护节点会被钳位到此电平,选择时需确认后端器件能承受该峰值电压。
  • 布局与散热:将 TVS 靠近需保护的输入/接口引脚放置,短且宽的接地回流路径有助于降低钳位电压和提高能量吸收能力。SOD-123FL 为小型封装,需注意 PCB 铜皮面积和散热设计以便在多次浪涌下保持稳定性能。
  • 多次冲击与退化:尽管器件能吸收高能脉冲,频繁的大能量浪涌可能导致性能退化。关键设备应考虑冗余或配合熔断、限流器件进行级联保护以延长寿命。

六、封装与可靠性

SOD-123FL 封装适合自动化贴装,体积小、寄生电感低,适用于高速信号旁的保护应用。器件在工业温度范围内(-55℃ ~ +150℃)仍能维持低漏电、稳定击穿和钳位特性。符合 IEC 61000-4-2 表明其具备对静电放电事件的防护能力,具体的级别和测试条件请参考完整数据手册以获得精确指标。

七、结论与建议

SMF24A_R1_00001 是一款面向 24V 级别系统的高能量、低漏电单向 TVS 器件,适合为电源线与接口提供可靠的瞬态浪涌和静电防护。选型时应关注 Vrwm 与系统静态电压的匹配、钳位电压对后端器件的要求,以及 PCB 布局与散热设计。欲获得更详细的电气特性曲线(如动态电阻、钳位电流关系、脉冲重复次数影响等),建议参考厂方完整版数据手册或直接联系 PANJIT 技术支持。

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.
